Establishment of a Latin American dataset to enable the construction of gestational weight gain charts for adolescents.

Gestational weight gain is an important indicator for monitoring nutritional status during pregnancy. However, there are no gestational weight gain references created for adolescents or national datasets to enable the construction of such graphs up to date. This manuscript aims to describe the creation of a Latin American dataset to construct gestational weight gain references for adolescents aged 10-19 years old. Gestational weight gain data from studies conducted in nine countries (Argentina, Brazil, Chile, Colombia, Mexico, Panama, Paraguay, Peru, and Uruguay) collected between 2003 and 2021 were harmonized. Data on height, weight, and gestational age in at least two gestational trimesters were included. Pregnant adolescents should be free of diseases that could affect weight, and newborns should weigh between 2,500-4,000 g and be free of congenital malformations. The final dataset included 6,414 individuals after data cleaning. Heterogeneity between the countries was assessed by calculating standardized site differences for GWG and z scores of height-for-age. Several imputation procedures were tested, and approximately 10% of the first-trimester weights were imputed. The prevalence of individuals with underweight (1.5%) and obesity (5.3%) was low, which may lead to problems when modeling the curves for such BMI categories. Maternal height and gestational weight gain did not show significant differences by country, according to the standardized site differences. A harmonized dataset of nine countries with imputed data in the first trimester of pregnancy was prepared to construct Latin American gestational weight gain curves for adolescents.

Gestational weight gain charts for Latin American adolescents.

Monitoring gestational weight gain (GWG) throughout pregnancy among adolescents is important for detecting individuals at risk and timely intervention. However, there are no specific tools or guidelines for GWG monitoring of this group. We aimed to construct GWG charts for pregnant adolescents (10-19 years old) according to pre-pregnancy body mass index (BMI) using a pooled dataset from nine Latin American countries. Datasets from Argentina, Brazil, Chile, Colombia, Mexico, Panama, Paraguay, Peru, and Uruguay collected between 2003 and 2021 were combined after data cleaning and harmonization. Adolescents free of diseases that could affect GWG and who gave birth to newborns weighing between 2,500-4,000 g and free of congenital malformations were included. Multiple imputation techniques were applied to increase the sample size available for underweight and obesity categories. Generalized Additive Models for Location, Scale, and Shape were used to construct the charts of GWG according to gestational age. Internal and external validation procedures were performed to ensure that models were not over-adjusted to the data. The cohort included 6,414 individuals and 29,414 measurements to construct the charts and 1,684 individuals and 8,879 measurements for external validation. The medians (and interquartile ranges) for GWG at 40 weeks according to pre-pregnancy BMI were: underweight, 14.9 (11.9-18.6); normal weight, 14.0 (10.6-17.7); overweight, 11.6 (7.7-15.6); obesity, 10.6 kg (6.7-14.3). Internal and external validation showed that the percentages above/below selected percentiles were close to those expected, except for underweight adolescents. These charts describe the GWG throughout pregnancy among Latin American adolescents and represent a significant contribution to the prenatal care of this group. GWG cut-offs based on values associated with lower risks of unfavorable outcomes for the mother-child binomial should be determined before implementing the charts in clinical practice.

Correlation of body mass index and waist to height ratio with cardiovascular risk factors in Colombian preschool and school children.

Objective: To analyze the agreement between body mass index (BMI) and waist-to-height Ratio (WHtR) to identify preschool and school children with cardiovascular risk factors (CRFs). Methods: Three-hundred-twenty-one kids were divided into preschool (3-5 years) and school children (6-10 years). BMI was used to classify children as overweight or obese. Abdominal obesity was defined with a WHtR ≥0.50. Fasting blood lipids, glucose and insulin were measured, and the homeostasis model assessment of insulin resistance (HOMA-IR) was calculated. The presence of CRFs and multiple non-waist circumference (non-WC) metabolic syndrome factors (MetS-Factors) [high HOMA-IR, high triglycerides and low high-density lipoprotein cholesterol (HDL-C)] were analyzed. Results: One-hundred-twelve preschool and 209 school children were evaluated. WHtR ≥0.50 classified abdominal obesity in more than half of the preschool children, exceeding those classified with overweight+obesity by BMI (59.5% vs. 9.8%; p<0.001). There was no agreement between WHtR and BMI to identify preschool kids with CRFs and multiple non-WC MetS-Factors (kappa: 0.0 to 0.23, p>0.05). There were similar proportions of school children classified with abdominal obesity by the WHtR and overweight+obesity by the BMI (18.7% vs. 24.9%; p>0.05). There was substantial agreement between WHtR and BMI to identify school children with high total cholesterol values, low-density lipoprotein cholesterol (LDL-C), triglycerides, non-HDL-C, insulin, HOMA-IR, low HDL-C values, and the presence of multiple non-WC MetS-Factors (kappa: 0.616 to 0.857, p<0.001). Conclusion: In preschool children WHtR ≥0.5 disagree with BMI results, but in school kids, it has good agreement with the BMI to classify the children´s nutritional status and to identify those with CRFs.

Objetivo: Analizar el grado de acuerdo entre el índice de masa corporal (IMC) y la relación/cintura estatura (rCE) para identificar niños con factores de riesgo cardiovascular (FRC). Métodos: Estudio transversal analítico con 112 niños preescolares (3-5 años) y 209 escolares (6-10 años). El sobrepeso y la obesidad se clasificaron con el IMC y la obesidad abdominal con la rCE ≥0.50. Se tomaron muestras sanguíneas en ayuno para análisis de glucosa, insulina, lípidos y cálculo del índice HOMA-IR. Se analizó la presencia de FRC y de múltiples factores del síndrome metabólico (Factores-SinMet) diferentes a la cintura [HOMA-IR elevado, triglicéridos elevados y colesterol de alta densidad (HDL-C) bajo]. Resultados: rCE ≥0.50 clasificó con obesidad abdominal a más de la mitad de los niños preescolares, excediendo el número de niños clasificados con sobrepeso+obesidad por IMC (59.5% vs 9.8%; p<0.001). No hubo acuerdo entre el IMC y la rCE para identificar niños preescolares con FRC o múltiples Factores-SinMet diferentes a la cintura (kappa: 0.0 a 0.23, p>0.05). Fueron similares las proporciones de niños escolares clasificados con obesidad abdominal por la rCE o con sobrepeso+obesidad por el IMC (18.7% vs. 24.9%; p>0.05). Hubo acuerdo sustancial entre la rCE y el IMC para identificar niños escolares con valores elevados de colesterol total, colesterol de baja densidad, triglicéridos, colesterol no-HDL, insulina, HOMA-IR, valores bajos de HDL-C y la presencia de múltiples Factores-SinMet diferentes a la cintura (kappa: 0.616 a 0.857, p<0.001). Conclusión: En niños preescolares la aplicación de rCE ≥0.5 no presenta acuerdo con el IMC, pero en escolares presenta un acuerdo sustancial con el IMC en la clasificación del estado nutricional y en la identificación de niños con FRC.

Malnutrición asociada con factores sociodemográficos en adultos mayores de Medellín (Colombia) / Malnutrition Associated with Sociodemographic Factors in Older Adults in Medellin, Colombia / Má nutrição associada a fatores sociodemográficos em idosos em Medellín-Colômbia

Introducción: los adultos mayores (AM) presentan riesgo de malnutrición (exceso o déficit de peso) debido a cambios fisiológicos, alimentarios, psicológicos y sociales derivados del envejecimiento. Objetivo: estimar la frecuencia de malnutrición por antropometría y el Mini Nutritional Assessment (MNA) en AM de Medellín (Colombia) y explorar su asociación con factores sociodemográficos. Materiales y métodos: estudio trans- versal con 1187 adultos ≥60 años, derivado del proyecto Propuesta técnica para el desarrollo del perfil de seguridad alimentaria y nutricional 2015, realizado en hogares de zona urbana y rural. Se tomaron como variables independientes las sociodemográficas, y como dependientes, las antropométricas y el MNA. La asociación entre malnutrición y variables sociodemográficas se determinó por modelos de regresión logística binaria y multinomial. Resultados: 65.2 % fueron mujeres, la edad promedio fue 70.0 ± 8.0 años; 61.5 % de estrato socioeconómico bajo, 65.9 % con nivel educativo primaria o inferior. Según el índice de masa corporal, 57.6 % presentó malnutrición, 20.8 % déficit de peso y 36.8 % exceso de peso. Según el MNA, 41.4 % tenía riesgo de desnutrición, y 5.4 %, desnutrición. Ambas condiciones se presentaron con mayor frecuencia en mujeres (OR = 2.0; IC95 %: 1.5-2.6), edades ≥75 años (OR = 1.7; IC95 %: 1.2-2.4), estrato socioeconómico bajo (OR = 3.2; IC95 %: 1.5-6.8), del área rural (OR = 1.7; IC95 %: 1.1-2.5), con estudios de primaria (OR = 2.1; IC95 %: 1.1-4.4) o sin educación (OR = 3.4; IC95 %: 1.5-7.5). Conclusión: la malnutrición en AM de Medellín es elevada y constituye un problema de salud pública, más frecuente en mujeres, edades avanzadas, zonas rurales, estratos socioeconómicos bajos y niveles educativos inferiores; condiciones que deben tenerse en cuenta para la implementación de políticas públicas

Introduction: Older adults (OA) are at risk of malnutrition (overnutrition or undernutrition) due to physio- logical, feeding, psychological, and social changes associated with aging. This study aimed to estimate the frequency of malnutrition using anthropometry and the Mini-Nutritional Assessment (MNA) among OA in Medellin, Colombia, and explore the association of malnutrition with sociodemographic factors. Methods: A cross-sectional study derived from the Technical Proposal for the Development of the Food and Nutrition Security Profile, 2015 was performed with 1187 adults aged ≥60 years old among urban and rural households. The sociodemographic characteristics were considered as independent variables, and anthropometric and MNA data were defined as dependent variables. To establish the association between malnutrition and sociodemographic variables, binary and multinomial logistic regression models were used. Results: The average age of the participants was 70.0 ± 8.0 years old; 65.2% were women; 61.5% were of low socioeconomic status; and 65.9% attained primary education or lower. Based on body mass index, 57.6% had malnutrition, 20.8% were undernutrition, and 36.8% were overweight/obese. According to the MNA, 5.4% had malnutrition, while 41.4% were at risk of malnutrition. Both conditions occurred more frequently in women (OR = 2.0; 95% confidence interval [CI]: 1.5­2.6), aged ≥75 years old (OR = 1.7; 95% CI: 1.2­2.4), with low socioeconomic status (OR = 3.2; 95% CI: 1.5­6.8), from rural areas (OR = 1.7; 95% CI: 1.1­2.5), with primary education (OR = 2.1; 95% CI: 1.1­4.4) or no education (OR = 3.4; 95% CI: 1.5­7.5). Conclusion: Malnutrition among OA in Medellin, Colombia, is high, especially among women living in rural areas with low socioeconomic status and education level. The study findings indicate a public health problem. These conditions must be considered in the implementation of public policies

Introdução: os idosos (AM de adultos mayores) estão sob risco de má nutrição (excesso de peso ou desnu- trição) devido às alterações fisiológicas, dietéticas, psicológicas e sociais decorrentes do envelhecimento. O objetivo deste estudo foi estimar a frequência de má nutrição por antropometria e pelo Mini Nutritional Assessment (MNA) em AM de Medellín-Colômbia e explorar sua associação com fatores sociodemográficos. Materiais e métodos: estudo transversal com 1187 adultos ≥ 60 anos, derivados do projeto Proposta técnica para elaboração do perfil de Segurança Alimentar e Nutricional 2015, realizado em domicílios de áreas urbanas e rurais. Variáveis sociodemográficas foram consideradas como variáveis independentes e as variáveis antropométricas e MNA como variáveis dependentes. A associação entre a má nutrição e as variáveis sociodemográficas foi determinada por modelos de regressão logística binária e multinomial. Resultados: 65.2% eram mulheres, idade média 70.0 ± 8.0 anos; 61.5% de estrato socioeconômico baixo, 65.9% com nível de escolaridade fundamental ou inferior. De acordo com o índice de massa corporal (IMC), 57.6% apresentaram desnutrição, 20.8% magreza e 36.8% excesso de peso. Segundo o MNA, 41.4% estavam em risco de desnutrição e 5.4% já apresentavam desnutrição. Ambas as condições ocorreram com maior frequência em mulheres (or = 2.0; Ic 95%: 1.5-2.6), idade ≥ 75 anos (or = 1.7; Ic 95%: 1.2-2.4), baixo nível socioeconômico (or = 3.2; Ic 95%: 1.5-6.8), da zona rural (or = 1.7; Ic 95%: 1.1-2.5), com ensino fundamental (or = 2.1; Ic 95%: 1.1-4.4) ou sem escolaridade (or = 3.4; Ic 95%: 1.5-7.5). Conclusão: a má nutrição em AM de Medellín é alta, constituindo um problema de saúde pública, mais frequente em mulheres, idades avançadas, áreas rurais, estratos socioeconômicos baixos e níveis educacionais mais baixos; condições que devem ser levadas em conta para a implementação de políticas públicas

Handgrip strength in older adults from Antioquia-Colombia and comparison of cutoff points for dynapenia.

Handgrip strength is a predictor of functional impairment and presence of morbimortality in older adults. However, appropriate reference values and cutoff points are required for its optimal use. This study describes handgrip characteristics in the older adult population of Antioquia-Colombia and compares the dynapenia handgrip cutoffs proposed for Colombians with international criteria. A cross-sectional study including 1592 older adults was done. Dynapenia prevalence by handgrip was analyzed using the following cutoffs: European Consensus of Sarcopenia (2018), Asian Working Group for Sarcopenia (2019), Chilean (2018), and Colombian (2019). Handgrip strength significantly decreased with aging, showing a positive and strong association with functional and health parameters. The highest prevalence of dynapenia was found with the Asian Consensus cutoffs (26.1%) and the lowest with the Colombian cutoffs (0.8%). Low agreement was found between the Colombian cutoffs with the European Consensus (kappa = 0.059; p < 0.001), the Asian Consensus (kappa = 0.039; p < 0.001) and the Chilean proposal (kappa = 0.053; p < 0.001). Dynapenia using the Chilean, European, and Asian cutoffs was associated with physical inactivity, presence of multimorbidity, slow gait speed, nutritional risk, and low calf circumference. Meanwhile, the Colombian cutoffs was only associated with slow gait speed and low calf circumference. The handgrip cutoffs proposed for Colombians seems to underestimate the dynapenia prevalence in older people from Antioquia. Furthermore, these cutoff points did not show associations with relevant functional and health parameters. The handgrip cutoffs proposed for Colombians should be used with caution.

Factores asociados al cumplimiento de las recomendaciones de actividad física de la Organización Mundial de la Salud, en los adultos de Antioquia - Colombia

Objetivo: Describir los factores asociados al cumplimiento de las recomendaciones de actividad física (AF) de la Organización Mundial de la Salud, en los adultos de Antioquia. Metodología: Se realizó un análisis transversal de la base de datos del "Perfil alimentario y nutricional de Antioquia". La AF se indagó en 2757 adultos (18-64 años), utilizando el "Cuestionario mundial de actividad física" de la Organización Mundial de la Salud. Se hicieron análisis bivariados y multivariados, explorando la relación de variables socioeconómicas, demográficas y de estado nutricional, con el cumplimiento de las recomendaciones de AF. Resultados: Se observó una mayor prevalencia de cumplimiento de las recomendaciones de AF en hombres que mujeres (60,8 vs. 48,0 %; p< 0,001) y en adultos jóvenes (18-29 años) que en mayores de 29 años (66,8 vs. 49,3 %; p< 0,001). Además, se presentó más alta proporción de cumplimiento de las recomendaciones de AF en personas de mayor estrato socioeconómico, mayor nivel educativo y residentes del área urbana. Ser mujer, pertenecer al estrato socioeconómico 1, poseer secundaria o un nivel de educación inferior, y tener como ocupación oficios del hogar se asociaron con una probabilidad menor de cumplir las recomendaciones de AF; por el contrario, ser una persona joven se asocia con un mayor cumplimiento. Conclusión: Son evidentes las desigualdades en el cumplimiento de las recomendaciones de AF por los adultos de Antioquia. Se deben priorizar las mujeres, las personas mayores de 30 años, de bajo estrato socioeconómico y de bajo nivel educativo en los planes y programas orientados a promover la práctica de la AF en el departamento.

Objective: To describe the factors associated with adherence to the World Health Organization's physical activity (PA) recommendations in adults from Antioquia-Colombia. Methodology: A cross-sectional analysis of the database of the "Food and nutritional Profile of Antioquia" was carried out. PA was inquired in 2,757 adults (18-64-year-olds), using the World Health Organization's "Global Physical Activity Questionnaire". Bivariate and multivariate analyses were performed, exploring the relationship between socioeconomic, demographic and nutritional status variables and adherence to PA recommendations. Results: A higher prevalence of adherence to PA recommendations was observed in men compared to women (60.8 vs. 48.0 %; p < 0.001) and in young adults (18-29) compared to in adults older than 29 years of age (66.8 vs. 49.3 %; p < 0.001). In addition, adherence to PA recommendations was higher in people with high socioeconomic status, a high educational level and residents of urban areas. Being a woman, belonging to socioeconomic stratum 1, having high school or a lower level of education, and having as an occupation household chores were associated with a lower probability of adherence to PA recommendations; while being young is associated with greater adherence. Conclusion: Inequalities in adherence to FA recommendations by adults in Antioquia are evident. Women and people over 30 years of age with low socioeconomic status and low educational levels should be prioritized in plans and programs aimed at promoting the practice of PA in the department.

Objetivo: Descrever os fatores associados ao cumprimento das recomendações de atividade física (AF) da Organização Mundial da Saúde, nos adultos de Antioquia. Metodologia: Realizou-se uma análise transversal da base de dados do "Perfil alimentar e nutricional de Antioquia". A AF indagou-se em 2757 adultos (18-64 anos), usando o "Questionário mundial de atividade física" da Organização Mundial da Saúde. Fizeram-se análises bivariadas e multivariadas, explorando a relação de variáveis socioeconômicas, demográficas e de estado nutricional, com o cumprimento das recomendações de AF. Resultados: Observou-se uma maior prevalência de cumprimento das recomendações de AF em homens do que em mulheres (60,8 vs. 48,0%; p>0,001) e em jovens adultos (18-29 anos) do que em maiores de 29 anos (66,8 vs. 49,3%; p>0,001). Além disso, apresentou-se proporção mais alta de cumprimento das recomendações de AF em pessoas de mais alto estrato socioeconômico, maior nível educativo e residentes da área urbana. Ser mulher, pertencer ao estrato socioeconômico 1, possuir grau de secundária ou um nível inferior de educação e ter como ocupação trabalhos do lar associaram-se com uma probabilidade menor de cumprir as recomendações de AF; pelo contrário, ser uma pessoa jovem associa-se com um maior cumprimento. Conclusão: São evidentes as desigualdades no cumprimento das recomendações de AF pelos adultos de Antioquia. Devem-se priorizar as mulheres, as pessoas maiores de 30 anos, de estrato socioeconômico baixo e de baixo nível educativo nos planos e programas orientados a promover a prática da AF no departamento.

Inseguridad alimentaria en hogares donde habitan adultos mayores. Medellín, Colombia / Food Insecurity in Households Inhabited by Older Adults, Medellín, Colombia / Insegurança alimentar em lares onde habitam idosos: Medellin, Colômbia

Resumen Objetivo: Determinar la inseguridad alimentaria y algunas características sociodemográficas asociadas a ella, en hogares de Medellín (Colombia) en los que habitaban adultos de 60 años o más. Metodología: Estudio transversal, de muestreo aleatorio estratificado, por nivel socioeconómico y localización geográfica (urbano-rural). Este estudio se basó en 935 hogares, en los cuales habitaba por lo menos un adulto mayor. La seguridad alimentaria se midió con la Escala Latinoamericana y Caribeña de Seguridad Alimentaria. Se utilizaron la prueba chi cuadrado (χ2) y odds ratio (or), con intervalos de confianza, para determinar la asociación de la seguridad alimentaria con las demás variables; además, se elaboró un árbol de clasificación, con el propósito de determinar la importancia relativa de las variables para explicar la seguridad alimentaria. Resultados: El 19,2 % de los hogares estaba conformado únicamente por adultos mayores. El 63 % de los hogares evaluados presentaron jefaturas femeninas. La inseguridad alimentaria fue del 55 %, con mayores proporciones en zonas rurales, estratos bajos y cuando se presenta mayor número de personas por hogar (p < 0,05); la inseguridad alimentaria fue más baja en hogares integrados solo por adultos mayores (or = 0,58; p < 0,001), con jefes de hogar de 60 años y más (or = 0,64; p = 0,003) y hogares que no contaban con programas de ayuda alimentaria dirigidos a adultos mayores (or = 0,33; p < 0,001). Conclusión: Este estudio evidencia una alta frecuencia de inseguridad alimentaria en hogares donde viven adultos mayores; además, la edad, el sexo del jefe del hogar y el que este esté conformado solo por adultos mayores son aspectos determinantes de la inseguridad alimentaria.

Abstract Objective: To determine food insecurity and certain associated sociodemographic characteristics in households inhabited by adults aged 60 years or older in Medellín (Colombia). Methodology: Cross-sectional study using stratified random sampling according to socioeconomic status and geographic area (urban-rural). This study examined 935 households that had at least one older adult. Food security was measured with the Latin American and Caribbean Food Security Scale. The chi-square test (χ2) and odds ratio (OR) with confidence intervals were used to determine the relationship between food security and the other variables; additionally, a classification tree was created to identify the relative importance of the variables in explaining food security. Results: Only 19.2% of the households were comprised entirely of older adults. 63% of the examined households presented female headships. Food insecurity was 55%, with higher rates in rural areas, lower socioeconomic strata, and households with more people (p < 0.05); food insecurity was lower in households composed entirely of older adults (OR = 0.58; p < 0.001), households with heads of household aged 60 years or older (OR = 0.64; p = 0.003), and households without food aid programs for older adults (OR = 0.33; p < 0.001). Conclusion: This study suggests a significant prevalence of food insecurity in households headed by older adults; furthermore, the head of household's age, gender, and whether the home is exclusively composed of older adults are all determinants of food insecurity.

Resumo Objetivo: Determinar a insegurança alimentar e algumas características sociodemográficas associadas a ela, em lares de Medellin (Colômbia) nos quais habitam adultos com idades a partir de 60 anos. Metodologia: Estudo transversal, de amostragem aleatória estratificado, por nível socioeconômico e localização geográfica (urbano-rural). Este estudo foi baseado em 935 lares, nos quais habitava pelo menos um idoso. A segurança alimentar foi medida com a Escala Latino-americana e Caribenha de Segurança Alimentar (ELCSA). Foram utilizadas o teste qui-quadrado (X²) e odds ratio (OR), com intervalos de confiança para determinar a associação da segurança alimentar com as outras variáveis; além disso, foi elaborada uma árvore de classificação com o propósito de determinar a importância relativa das variáveis para explicar a segurança alimentar. Resultados: Um total de 19,2% dos lares estava formado somente por idosos. 63% dos lares avaliados apresentavam chefes de famílias do sexo feminino. A insegurança alimentar foi de 55% com maiores proporções em zonas rurais, de baixa renda e quando se apresentou um maior número de pessoas por lar (p < 0,05); a insegurança alimentar foi mais baixa em lares integrados somente por idosos (OR =0,58; p < 0,001), com chefes de família de 60 anos ou mais (OR = 0,64; p = 0,003) e lares que não contavam com programas de ajuda alimentar dirigidos a idosos (OR = 0,33; p < 0,001). Conclusões: Este estudo evidencia uma alta frequência de insegurança alimentar em lares onde vivem idosos; além da idade, o sexo do chefe de família e o fato de que esteja formado somente por idosos são aspectos determinantes da insegurança alimentar.

Enfermedades cardiometabólicas y la mortalidad por el COVID-19 en el inicio de la pandemia en Colombia / Cardiometabolic Diseases and Mortality due to COVID-19 During the Pandemic's Onset in Colombia / Doenças cardiometabólicas e mortalidade por COVID-19 no início da pandemia na Colômbia

Resumen: el escenario de la pandemia actual derivada del COVID-19, infección causada por el virus denominado SARS-CoV-2, ha permitido develar la interacción entre enfermedades infecciosas y enfermedades crónicas no transmisibles, de manera que ha aportado hallazgos que sugieren un aumento en las tasas de mortalidad por COVID-19. El objetivo de este artículo es describir las características sociodemográficas y de morbilidad en los fallecimientos ocurridos en Colombia por COVID-19 al 19 de mayo del 2020. Es un estudio descriptivo a partir de reportes del Instituto Nacional de Salud, sobre fallecimientos de casos positivos por COVID-19, del 6 de marzo al 19 de mayo del 2020. La información sobre factores preexistentes se obtuvo de reportes del periódico El Tiempo en notas de prensa publicadas al respecto. Se realizó análisis descriptivo en Excel y SPSS v25. Se identificaron 613 fallecimientos en el periodo. El mayor número de muertes ocurrió en Bogotá D. C. (35,0 %), seguida de Valle de Cauca (10,4 %), Cartagena (8,6 %), Amazonas (7,2 %) y Meta (5,6 %). La edad promedio de las defunciones fue 67,26 ± 16,28 años, siendo el grupo de edad de 60-79 años en el que más muertes se presentaron, con el 50,7 % de los casos. El 60,8 % de las defunciones ocurrió en personas de sexo masculino, y un 80,1 % tenían alguna morbilidad: 36,2 % padecía hipertensión, 19,2 % diabetes mellitus, 17,1 % EPOC, 16,5 % alguna enfermedad cardiovascular, 11,1 % obesidad y un 16,2 % padecía otro tipo de enfermedad sin especificar. El antecedente de morbilidad por patologías cardiometabólicas asociadas con factores alimentarios y nutricionales favorece la mortalidad en personas infectadas por COVID-19 en Colombia.

Inequalities in food consumption the Colombian households: Results from the National Survey of Nutritional Status / Desigualdades en el consumo de alimentos en hogares colombianos: Resultados de la Encuesta Nacional de Situación Nutricional / Desigualdades no consumo de alimentos em lares colombianos: Resultados da Enquete Nacional de Situação Nutricional

Abstract Introduction: adverse socioeconomic conditions may cause food intake characterized by inequality that derives in malnutrition increases. Objective. To identify inequalities in food consumption among the Colombian population according to socioeconomic status and the food security classification for households. Methods. The data were obtained from the 2005 National Survey of Nutritional Status, and the analysis used the first 24-hour recall n=39,413 Colombians. The statistical analysis took into account descriptive statistics and 95% confidence intervals. A multivariate analysis was performed through multinomial logistic regression models, with each of the food groups as a dependent variable. Finally, a latent class analysis was performed to understand the heterogeneity of the inequalities in food consumption in the households. Results. Low-socioeconomic status households showed higher consumption of cereals, tubers and plantains, non-alcoholic beverages, and fats. I contrast, higher socioeconomic status households showed higher consumption of dairy products, fruit, vegetables, and sugars/sweets. The food security classification found that food-secure households had a higher consumption of meat, dairy, vegetables, fruit, and sugars/sweets. Households classified as food-insecure showed a higher consumption of cereals, tubers and plantains, and non-alcoholic beverages. The consumption of tubers and plantains showed a clear social gradient, in higher socioeconomic status there was lower consumption probability of those products. Conclusion. There are inequalities in food consumption in Colombia according to socioeconomic status and the food security classification; therefore, people and families with the most unfavorable socioeconomic status have diets with less nutritional value.

Resumen Objetivo: Identificar las inequidades en el consumo de alimentos según nivel socioeconómico y clasificación de seguridad alimentaria de los hogares colombianos. Métodos: Los datos provienen de la Encuesta Nacional de la Situación Nutricional de 2005, y se utilizó el primer recordatorio de 24 horas n=39,413 colombianos. El análisis estadístico tuvo en cuenta estadística descriptiva e intervalos de confianza del 95%. Se realizó un análisis de regresión logística multinomial, con cada uno de los grupos de alimentos como una variable dependiente. Finalmente, se realizó un análisis de clases latentes para capturar la heterogeneidad de las inequidades en el consumo de alimentos en los hogares. Resultados: Los hogares clasificados con un nivel socioeconómico bajo mostraron un mayor consumo de cereales, tubérculos/plátanos, bebidas no alcohólicas y grasas. Por otro lado, se observó que un nivel socioeconómico alto conllevó un mayor consumo de lácteos, frutas, verduras y azúcares/postres. Según clasificación de seguridad alimentaria, los hogares considerados en seguridad tenían un mayor consumo de carne, lácteos, verduras, frutas y azúcares/postres. Los hogares clasificados en inseguridad alimentaria mostraron mayor consumo de cereales, tubérculos/plátanos, y bebidas no alcohólicas. El consumo de tubérculos y plátanos mostró un gradiente social, con menor probabilidad de consumo a mayor nivel socioeconómico. Conclusión: Existen inequidades en el consumo de alimentos en Colombia según nivel socioeconómico y clasificación de seguridad alimentaria, por tanto, las personas y familias en estado socioeconómico más desfavorable tienen dietas con menor valor nutricional.

Resumo Objetivo: Identificar as desigualdades no consumo de alimentos segundo o nível socioeconômico e classificação de segurança alimentar dos lares colombianos. Métodos: Os dados provêm da Enquete Nacional da Situação Nutricional de 2005, e se utilizou o primeiro lembrete de 24 horas n=39,413 colombianos. A análise estatístico levando em conta Estatísticas descritiva e intervalos de confiança de 95%. Realizou-se uma análise de regressão logística multinominal, com cada um dos grupos de alimentos como uma variável dependente. Finalmente, realizou-se uma análise de classes latentes para capturar a heterogeneidade das desigualdades no consumo de alimentos nos lares. Resultados: Os lares classificados com um nível socioeconómico baixo amostraram um maior consumo de cereais, tubérculos/ banana da terra, bebidas não alcoólicas e gorduras. Por outro lado, observou-se que um nível socioeconómico alto tem um maior consumo de lácteos, frutas, verduras e açúcares/sobremesas. Segundo a clasificação de segurança alimentar, os lares considerados em segurança tinham um maior consumo de carne, lácteos, verduras, frutas e açúcares/sobremesas. Os lares classificados em insegurança alimentar evidenciaram maior consumo de cereais, tubérculos/banana da terra, e bebidas não alcoólicas. O consumo de tubérculos e banana da terra evidenciou uma desigualdade social, com menor probabilidade de consumo no nível socioeconômico mais alto. Conclusão: Existem desigualdades no consumo de alimentos na Colômbia de acordo com o nível socioeconômico e classificação de segurança alimentar. Deste modo, as pessoas e famílias em condições socioeconômicos mais desfavoráveis têm dietas com menor valor nutricional.

Ecuaciones para estimar la talla de ancianos colombianos mediante la altura de la rodilla / Estimation equations for the height of Colombian elders using knee height

Introducción. La estatura en el anciano no refleja su talla real de adulto joven debido al envejecimiento de su columna vertebral, entre otros aspectos. Objetivo. Proponer ecuaciones para estimar la talla de los ancianos colombianos mediante la altura de la rodilla, según el grupo étnico y el sexo. Materiales y métodos. Se hizo un análisis secundario del estudio transversal SABE 2015, utilizando un diseño muestral probabilístico y multietápico en personas colombianas de 60 o más años. Se seleccionaron aleatoriamente dos grupos de la base de datos del estudio SABE: el grupo para el desarrollo de las ecuaciones y el grupo para su validación. Se hizo un análisis de regresión lineal múltiple para estimar la estatura mediante la altura de la rodilla en los grupos étnicos (indígenas, afrodescendientes y blancos-mestizos) por edad y sexo; los resultados se validaron en cada subgrupo de estudio. Resultados. Se diseñaron seis ecuaciones por sexo (hombres=3.665, mujeres=3.019) y etnia; los coeficientes de determinación ajustados (R2 ) de las ecuaciones en hombres de los tres grupos étnicos oscilaron entre 64 y 75 % y, los errores estándar, entre 3,09 y 3,93 cm. En las mujeres, los R2 de las tres ecuaciones fluctuaron entre 53 y 73 % y los EE, entre 2,96 y 3,90 cm. Conclusión. La ecuación con mejor capacidad para estimar la talla del anciano colombiano fue la obtenida para los afrodescendientes de ambos sexos, en tanto que en la población indígena se presentaron los menores coeficientes de determinación.

Introduction: The height in the elderly does not reflect their real size as young adults due to the aging of their spine, among other aspects. Objective: To estimate the equations to predict the height in Colombian elders according to their ethnic group and sex using the knee height measurement. Materials and methods: We conducted a secondary analysis of the SABE, 2015, crosssectional study using a multistage probabilistic sampling design in people aged 60 years and over in Colombia. We randomly selected two groups from the study's database: A development group and a validation group of the equations. Age and anthropometric characteristics were similar in both groups. We performed a multiple linear regression analysis to predict the height using knee height measurement in the different ethnic groups (Indigenous, Afro-descendant, and white-mestizo groups) by age and sex; the results were validated in each selected subgroup. Results: We designed six equations by sex (men=3,665; women=3,019) and ethnic group. The adjusted R2 of the equations in men from the three ethnic groups oscillated between 64% and 75% and the standard errors, between 3,09 and 3,93 cm while in women, the R2 s of the three equations ranged between 53% and 73% and the EEs, between 2,96 and 3,90 cm. Conclusion: The equation with the best predictive capacity of the height of Colombian elders was obtained for African descendants of both sexes. The lowest coefficients of determination were obtained for the indigenous population.

Intra-observer reliability of the anthropometric measurements in South American children and adolescents: the SAYCARE Study / Confiabilidad intraobservador de mediciones antropométricas en niños y adolescentes sudamericanos: Estudio SAYCARE

Introduction: the South American Youth/Child Cardiovascular and Environmental (SAYCARE) feasibility study aims to develop valid and reliable indicators to investigate health-related behavior and nutritional status in children and adolescents. Anthropometric measurements are one of the evaluated indicators in the study. The accuracy of the anthropometric data is very important and relies in the quality of the measurements. Objective: to describe the intra-observer reliability of ten anthropometric measurements: weight, height, circumferences (neck, arm, waist, hip) and skinfolds (triceps, subscapular, biceps and suprailiac) of children and adolescents from six South American cities: Lima, Medellin, Montevideo, Santiago, San Pablo and Teresina. Methods: prior to the study, fieldworkers from the seven centers participated in central training to ensure the application of standardized procedures in the anthropometric measurements. Intra-observer precision, technical error of measurement (TEM) and coefficient of reliability (R) were estimated for each measurement. Results: reliability of weight and height was above 99% in almost all cities. TEM for skinfold thickness was below 1.4 mm in children and 2.13 mm in adolescents, while reliability was above 95% in most of the skinfold measurements. TEM for circumferences was below 1.8 cm in children and 0.64 cm in adolescents, while reliability was above 99% in almost all circumferences. Conclusions: reliability of the anthropometric measurements in this study was high. In comparison with similar European or American studies, the reliability of the measurements taken in our study was, in most cases, similar or even higher

Uno de estos indicadores son las mediciones antropométricas. La precisión de los datos antropométricos es muy importante y se basa en la calidad con que se toman las mediciones. Objetivos: describir la confiabilidad intraobservador de diez mediciones antropométricas: peso, talla, circunferencias (cuello, brazo, cintura, cadera) y pliegues (trÍceps, subscapular, bÍceps y suprailIaco) de niños y adolescentes de seis ciudades de Sudamérica: Lima, Medellín, Montevideo, Santiago, San Pablo and Teresina. Métodos: previo al estudio, los trabajadores de campo de los seis centros participaron de un entrenamiento centralizado, para asegurar la aplicación de procedimientos estandarizados en la toma de las mediciones antropométricas. Para determinar la precisión intraobservador, se estimó el error técnico de medición (TEM) y el coeficiente de confiabilidad (R) para cada medición. Resultados: la confiabilidad de las medidas de peso y la talla estuvo por encima del 99% en casi todas las ciudades. El TEM para el grosor de los pliegues estuvo debajo de 1,4 mm en los niños y de 2,13 mm en los adolescentes, mientras que la confiabilidad fue superior al 95% en la mayoría de las mediciones de los pliegues. El TEM para las circunferencias estuvo por debajo de 1,8 cm en los niños y de 0,64 cm en los adolescentes, mientras que la confiabilidad fue superior al 99% en casi todas las circunferencias. Conclusiones: la confiabilidad de las mediciones antropométricas en este estudio fue alta. Comparada con estudios similares realizados en Europa y Estados Unidos, la confiabilidad de las medidas tomadas en nuestro estudio es, en la mayoría de los casos, similar o aún más elevada

Waist-to-height ratio may be an alternative tool to the body mass index for identifying Colombian adolescents with cardiometabolic risk factors.

INTRODUCTION: Background: there is limited information about the usefulness of the waist-to-height ratio (WHtR) to identify Colombian adolescents with cardiometabolic risk factors (CRF). Objective: to compare the utility of WHtR, body mass index (BMI), and waist circumference (WC) to identify adolescents with CRF. Methods: a study with 346 youths (aged 14.0 ± 2.3 years) was performed. Anthropometric measurements were collected and BMI, WC and WHtR were calculated. Fasting blood lipids, glucose and insulin were measured; the homeostasis model assessment of insulin resistance (HOMA-IR) was computed. The presence of multiple non-WC metabolic syndrome (MetS) factors (high HOMA-IR, high triglycerides and low high-density lipoprotein cholesterol [HDL-C]) was analyzed. The area under the curve (AUC) and the odds ratios (OR) were calculated. Results: the BMI, WC and WHtR were comparable at identifying adolescents with high HOMA-IR (AUC = 0.686, 0.694 and 0.641, respectively), low HDL-C (AUC = 0.623, 0.652 and 0.572, respectively) and multiple non-WC MetS factors (AUC = 0.694, 0.715 and 0.688, respectively). The OR of having multiple non-WC MetS factors was similar in overweight adolescents (1.65, 95% CI: 0.86-3.14) and those with WHtR ≥ 0.50 (3.76, 95% CI: 1.95-7.3). There were no OR differences of having multiple non-WC MetS factors among adolescent with obesity (9.88, 95% CI: 3.1-31.7), WC ≥ P90 (18.3, 95% CI: 4.0-83.5) and WHtR ≥ 0.55 (11.0, 95% CI: 3.0-4.4). Conclusions: WHtR, BMI and WC have similar capacities to identify Colombian adolescents with CRF. WHtR showed to be an alternative tool to BMI and WC measurements when screening adolescents for cardiometabolic risk.

INTRODUCCIÓN: Introducción: hay información limitada sobre la utilidad de la relación cintura-estatura (rCE) para identificar adolescentes colombianos con factores de riesgo cadiometabólicos (FRC). Objetivo: comparar la utilidad de la rCE, el índice de masa corporal (IMC) y la circunferencia de cintura (CC) para identificar adolescentes con FRC. Metodología: se evaluaron 346 jóvenes (14,0 ± 2,3 años). Se obtuvieron medidas antropométricas, IMC, CC, rCE, glucosa, insulina y lípidos sanguíneos en ayunas e índice HOMA-IR. Se analizó la presencia de múltiples factores del síndrome metabólico (MetS) diferentes a la CC (HOMA-IR alto, triglicéridos aumentados, concentración del colesterol de alta densidad [HDL-C] baja). Se calculó el área bajo la curva (AUC) y razón de ventajas (OR). Resultados: el IMC, CC y rCE fueron similares para identificar adolescentes con alto HOMA-IR (AUC = 0,686, 0,694 y 0,641, respectivamente), bajo HDL-C (AUC = 0,623, 0,652 y 0,572, respectivamente) y múltiples factores del MetS diferentes a la CC (AUC = 0,694, 0,715 y 0,688, respectivamente). La OR de tener esta última condición fue similar en adolescentes con sobrepeso (1,65, IC 95%: 0,60-3,14) y aquellos con rCE ≥ 0,50 (3,76, IC 95%: 1,95-7,3). La presencia de múltiples factores del MetS diferentes a la CC en adolescentes con obesidad (9,88, IC 95%: 3,1-31,7), CC ≥ P90 (18,3, IC 95%: 4,0-83,5) y rCE ≥ 0,55 (11,0, IC 95%: 3,0 a 4,4) fue similar. Conclusión: rCE, IMC y CC tienen capacidades similares para identificar adolescentes colombianos con FRC. El rCE demostró ser una herramienta alternativa al IMC y la CC cuando se tamizan adolescentes para identificar la presencia de FRC.

Reliability and validity of body weight and body image perception in children and adolescents from the South American Youth/Child Cardiovascular and Environmental (SAYCARE) Study.

OBJECTIVE: To assess the reliability and validity of body weight (BW) and body image (BI) perception reported by parents (in children) and by adolescents in a South American population. DESIGN: Cross-sectional study. BW perception was evaluated by the question, 'Do you think you/your child are/is: severely wasted, wasted, normal weight, overweight, obese?' BI perception was evaluated using the Gardner scale. To evaluate reliability, BW and BI perceptions were reported twice, two weeks apart. To evaluate validity, the BW and BI perceptions were compared with WHO BMI Z-scores. Kappa and Kendall's tau-c coefficients were obtained. SETTING: Public and private schools and high schools from six countries of South America (Argentina, Peru, Colombia, Uruguay, Chile, Brazil).ParticipantsChildren aged 3-10 years (n 635) and adolescents aged 11-17 years (n 400). RESULTS: Reliability of BW perception was fair in children's parents (κ=0·337) and substantial in adolescents (κ=0·709). Validity of BW perception was slight in children's parents (κ=0·176) and fair in adolescents (κ=0·268). When evaluating BI, most children were perceived by parents as having lower weight. Reliability of BI perception was slight in children's parents (κ=0·124) and moderate in adolescents (κ=0·599). Validity of BI perception was poor in children's parents (κ=-0·018) and slight in adolescents (κ=0·023). CONCLUSIONS: Reliability of BW and BI perceptions was higher in adolescents than in children's parents. Validity of BW perception was good among the parents of the children and adolescents with underweight and normal weight.

Malnutrición y su relación con aspectos de salud en adultos mayores / Malnutrition in relationship with aspects of health in elderly people

INTRODUCCIÓN: Los adultos mayores presentan riesgo de malnutrición por los cambios durante el envejecimiento en lo físico, síquico y social, además de las modificaciones en los hábitos de vida. OBJETIVO: Explorar la relación entre la malnutrición con aspectos de salud y hábitos de vida en un grupo de adultos mayores no institucionalizados. MATERIALES Y MÉTODOS: Estudio transversal en 178 adultos ≥ 60 años que asistieron a consulta odontológica en una universidad de la ciudad de Medellín-Colombia. Se incluyeron a quienes estuvieran en capacidad de responder los cuestionarios y sin limitaciones físicas que impidieran la toma de medidas antropométricas. Como variable dependiente se consideró la malnutrición según el Mini Nutritional Assessment; como variables independientes se incluyeron los aspectos demográficos, indicadores de salud bucal objetiva y subjetiva, percepción de salud, riesgo de depresión y hábitos de vida. Se utilizó un modelo de regresión logística para establecer la asociación del riesgo de malnutrición/malnutrición con las demás variables evaluadas. RESULTADOS: Según el Mini Nutritional Assessment, 31,5% de los adultos mayores presentaron riesgo de malnutrición/malnutrición, porcentaje significativamente más elevado en quienes no realizaban actividad física, con síntomas depresivos, con caries dental y un bajo índice de valoración de salud oral (p < 0.05). El modelo de regresión logística ajustado por sexo, edad, consumo de bebidas alcohólicas, hábito de fumar y actividad física, mostró que el riesgo de malnutrición/malnutrición se asoció con síntomas depresivos (OR=6,6 IC95%: 2,1-20,9), bajo índice de valoración de salud oral (OR=4,1 IC95%: 1,3-12,7), presencia de caries dental (OR=3,1 IC95%: 1,2-8,1) y número de medicamentos consumidos (OR=1,23 IC95%: 1,0-1,5). CONCLUSIÓN: La probabilidad de riesgo de malnutrición/malnutrición es más alta en adultos mayores con deterioro de la salud bucal, presencia de síntomas depresivos y número de medicamentos consumidos

INTRODUCTION: Older adults have risk of malnutrition because of changes in the ageing in physical, psychological and social aspects, also by modification in lifestyle. OBJECTIVE: To explore the relationship between malnutrition with aspects of health and lifestyle in a group of non-institutionalized elderly. MATERIALS AND METHODS: A cross-sectional study was conducted in 178 adults ≥ 60 years who attended dental appointments at University outpatient center of the city of Medellin. We included those who were able to answer the questionnaires and without physical limitations that would prevent the taking of anthropometric measurements. As dependent variable malnutrition, as assessed by the Mini Nutritional Assessment; as independent variables demographic aspects, indicators of objective and subjective oral health, health perception and depressive risk were considered. A logistic regression was used to establish the association of risk of malnutrition/malnutrition with independent variables. RESULTS: The percentage of people at risk of malnutrition/malnutrition was 31.5% according to Mini Nutritional Assessment. This percentage was significantly higher in adults who did not practice physical activity, with depressive symptoms, presence of dental caries and a low score of Geriatric Oral Health Assessment Index (p < 0.05). The crude logistic regression model and after adjusted for sex, age, alcohol consumption, smoking, physical activity, showed that the risk of malnutrition was associated with depressive symptoms (OR=6.6 95% CI: 2.1-20.9), low level of General Oral Health Assessment Index (OR=4.1 95% CI: 1.3-12.7), presence of dental caries (OR=3.1 95% CI 1.2-8.1) and drug number consumed (OR=1.23 95% CI: 1.0-1.5). CONCLUSION: The probability of risk of malnutrition/malnutrition was higher in older adults with impaired oral health, depressive symptoms and drug use

Development and validation of anthropometric equations to estimate body composition in adult women.

OBJECTIVE: To develop anthropometric equations to predict body fat percentage (BF%). METHODS: In 151 women (aged 18-59) body weight, height, eight- skinfold thickness (STs), six- circumferences (CIs), and BF% by hydrodensitometry were measured. Subjects data were randomly divided in two groups, equation-building group (n= 106) and validation group (n= 45). The equation-building group was used to run linear regression models using anthropometric measurements as predictors to find the best prediction equations of the BF%. The validation group was used to compare the performance of the new equations with those of Durnin-Womersley, Jackson-Pollock and Ramirez-Torun. RESULTS: There were two preferred equations: Equation 1= 11.76 + (0.324 x tricipital ST) + (0.133 x calf ST) + (0.347 x abdomen CI) + (0.068 x age) - (0.135 x height) and Equation 2= 11.37 + (0.404 x tricipital ST) + (0.153 x axilar ST) + (0.264 x abdomen CI) + (0.069 x age) - (0.099 x height). There were no significant differences in BF% obtained by hydrodensitometry (31.5 ±5.3) and Equation 1 (31.0 ±4.0) and Equation 2 (31.2 ±4.0). The BF% estimated by Durning-Womersley (35.8 ±4.0), Jackson-Pollock (26.5 ±5.4) and Ramirez-Torun (32.6 ±4.8) differed from hydrodensitometry (p <0.05). The interclass correlation coefficient (ICC) was high between hydrodensitometry and Equation 1 (ICC= 0.77), Equation 2 (ICC= 0.76), and Ramirez-Torun equation (ICC= 0.75). The ICC was low between hydrodensitometry and Durnin-Womersley (ICC= 0.51) and Jackson-Pollock (ICC= 0.53) equations. CONCLUSION: The new Equations-1 and 2, performed better than the commonly used anthropometric equations to predict BF% in adult women.

OBJETIVO: Desarrollar ecuaciones antropométricas para predecir el porcentaje de grasa corporal (%GC). MÉTODOS: En 151 mujeres (18-59 años) se midieron peso corporal, estatura, ocho pliegues cutáneos (PCs), seis perímetros (PEs) y el %GC por hidrodensitometría. Se formaron dos grupos al azar, desarrollo de ecuaciones (n=106) y validación (n= 45). En el grupo desarrollo ecuaciones se calcularon modelos de regresión lineal, con las medidas antropométricas como predictores, para encontrar la mejor ecuación de predicción del %GC. El grupo validación se utilizó para comparar el desempeño de las nuevas ecuaciones con las de Durnin-Womersley, Jackson-Pollock y Ramírez-Torun. RESULTADOS: Se seleccionaron dos ecuaciones: Ecuación-1= 11.76 + (0.324 x tríceps PC) + (0.133 x pantorrilla-medial PC) + (0.347 x abdomen PE) + (0.068 x edad-años) - (0.135 x estatura) y Ecuación-2= 11.37 + (0.404 x tríceps PC) + (0.153 x axilar PC) + (0.264 x abdomen PE) + (0.069 x edad-años) - (0.099 x estatura). No hubo diferencias significativas en el %GC obtenido por hidrodensitometría (31.5 ±5.3) y Ecuación-1 (31.0 ±4.0) o Ecuación-2 (31.2 ±4.0). Los %GC estimados por Durning-Womersley (35.8 ±4.0), Jackson-Pollock (26.5 ±5.4) y Ramírez-Torun (32.6 ±4.8) fueron diferentes del obtenido por hidrodensitometría (p <0.05). El coeficiente de correlación intraclase (ICC) fue alto entre hidrodensitometría y las Ecuaciones 1 (ICC= 0.77), 2 (ICC= 0.76), y Ramírez-Torun (ICC= 0.75). El ICC fue bajo entre hidrodensitometría y Durnin-Womersley (ICC= 0.51) y Jackson-Pollock (ICC= 0.53). CONCLUSIÓN: Las nuevas ecuaciones 1 y 2 presentaron mejor rendimiento que las ecuaciones tradicionales para predecir el %GC en mujeres adultas.

Development and validation of anthropometric equations to estimate body composition in adult women / Desarrollo y validación de ecuaciones antropométricas para estimar la composición corporal en mujeres adultas

Abstract Objective: To develop anthropometric equations to predict body fat percentage (BF%). Methods: In 151 women (aged 18-59) body weight, height, eight- skinfold thickness (STs), six- circumferences (CIs), and BF% by hydrodensitometry were measured. Subjects data were randomly divided in two groups, equation-building group (n= 106) and validation group (n= 45). The equation-building group was used to run linear regression models using anthropometric measurements as predictors to find the best prediction equations of the BF%. The validation group was used to compare the performance of the new equations with those of Durnin-Womersley, Jackson-Pollock and Ramirez-Torun. Results: There were two preferred equations: Equation 1= 11.76 + (0.324 x tricipital ST) + (0.133 x calf ST) + (0.347 x abdomen CI) + (0.068 x age) - (0.135 x height) and Equation 2= 11.37 + (0.404 x tricipital ST) + (0.153 x axilar ST) + (0.264 x abdomen CI) + (0.069 x age) - (0.099 x height). There were no significant differences in BF% obtained by hydrodensitometry (31.5 ±5.3) and Equation 1 (31.0 ±4.0) and Equation 2 (31.2 ±4.0).

The interclass correlation coefficient (ICC) was high between hydrodensitometry and Equation 1 (ICC= 0.77), Equation 2 (ICC= 0.76), and Ramirez-Torun equation (ICC= 0.75).

Design and Objectives of the South American Youth/Child Cardiovascular and Environmental (SAYCARE) Study.

OBJECTIVE: The purpose of this paper is to introduce the overarching study design of the South American Youth/Child Cardiovascular and Environmental (SAYCARE) study, which is an observational multicenter feasibility study held in seven South American cities: Buenos Aires (Argentina), Lima (Peru), Medellin (Colombia), Montevideo (Uruguay), Santiago (Chile), and São Paulo and Teresina (Brazil). Children and adolescents (3-17 years of age) were studied. METHODS: The data management systems, quality assurance monitoring activities, standardized operating procedure manuals, and training and study management are addressed in this paper. Various quality controls to ensure the collection of valid and reliable data are also discussed. RESULTS AND CONCLUSIONS: Data were obtained from 237 preschoolers and schoolchildren and 258 adolescents during the validation phase measurements. The results of the SAYCARE study are expected to provide higher accuracy in the assessment of cardiovascular disease risk factors, including eating behaviors, body composition, physical activity, sedentary behaviors, lipid profiles and cardiovascular health biomarkers, oral health, social conditions, environmental factors and home environment, and their determinants in children and adolescents from ages 3 to 17 in seven South American cities.
