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.

[Adolescent pregnancy: maternal characteristics and their association with birth weight of the newborn]. / Embarazo adolescente: características maternas y su asociación con el peso al nacer del neonate.

UNLABELLED: In Colombia, adolescent pregnancy is a public health problem, with serious implications for the health and nutrition of the binomial mother-child. OBJECTIVE: assess socio-demographic, economic, food security, health and maternal nutritional status characteristics by anthropometric measures in a group of pregnant adolescents in Medellin-Colombia on their third trimester of pregnancy and associate them with the newborns weight. METHODS AND MATERIALS: A cross sectional analytical study was made with 294 pregnant women (week 27 to 40), who participating in prenatal control program of the public hospital network in Medellin-Colombia. We sought Association of weight at birth with the explanatory variables. RESULTS: underweight in pregnant women was presented in families that had lower income wages than the Standard Minimum Wage Income--SMWI-, adolescents who were younger than 15 years old and those who had a gynecological age less than five years. In newborns, the highest proportion of small children for pregnancy age was found in mothers who presented infections, low pregnancy weight and low family income less than the minimum wage. For those whose earnings was less than the minimum income the newborn weight decreased 118g (CI 95%: -2.5 a - 234.7), in addition, for each kilogram that increased the pre-pregnancy weight, newborn weight increased in 10,26g (CI 95%: 1.98 a-18.5). CONCLUSIONS: low-weight pregnancy and low-weight newborns are associated with low family income. Pre-pregnancy weight, body mass index in the third trimester of pregnancy and mother's presence of urinary tract and vaginal infections were associated with the newborn's weight.

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.

Validation of the NOVA score for the consumption of ultra-processed foods by young women of Medellín, Colombia.

Ultra-processed foods (UPFs) are associated with deterioration in dietary quality and the development of chronic diseases. The NOVA score, developed in Brazil to assess UPF consumption quickly and inexpensively, is adapted and validated here using a sample of 203 young women from Medellín, Colombia. Food consumption was evaluated using 24-hour dietary recall and with the NOVA-UPF score. Food items were classified using the NOVA categories. The energy consumed from UPFs and its percentage of the total energy consumed was estimated. The association between the NOVA-UPF score and the percentage of energy from UPF (%UPF/E) was evaluated. Both variables were categorized into quintiles and concordance was estimated using prevalence and bias-adjusted kappa (PABAK). A regression model was used to assess the association between the NOVA-UPF score and critical nutrients. The mean NOVA-UPF score among study participants was 4.5, with 27% of the total energy they consumed coming from UPFs. There was a positive, linear association between the NOVA-UPF score and %UPF/E (p < 0.001) and substantial agreement (PABAK = 0.75) in the classification of participants between UPF energy quintiles and NOVA-UPF score quintiles. The NOVA-UPF score was positively and significantly associated with sodium, total fat, and saturated fat intake. We conclude that the adapted NOVA-UPF score may help monitor the consumption of UPFs among young women in Medellín.

Dietary intake assessment in a group of breastfeeding women in two populations of Antioquia, Colombia, 2021-2022 / Evaluación de ingesta dietética en un grupo de mujeres lactantes en dos poblaciones de Antioquia, Colombia, 2021-2022

Objectives: To describe the prevalence of the risk of under or overnutrition and the food intake pattern vis à vis the recommendations of the Ministry of Health and Social Protection and the Colombian Family Welfare Institute. Material and methods: Descriptive cross-sectional study carried out in healthy women receiving care in two hospitals of eastern Antioquia, with food and nutrition security in accordance with the Latin American and Caribbean Food Security Scale (ELCSA), in the first trimester of breastfeeding, assessed between 2021 and 2022. The clinical record was used as the source of information. The sociodemographic, clinical, anthropometric characteristics, as well as dietary and micronutrient intake, were measured. Descriptive statistics were used. The prevalence of deficient or excessive energy intake and the food consumption score (FCS) are presented. The EVINDI v5, PC-SIDE v1.0, Stata 16.1 and Jasp 0.16.4 software packages were used. Results: Overall, 30 breastfeeding women were included. The prevalence of the risk of deficient energy intake was 43 %, while the risk of excessive intake was 16 % and the risk of protein deficiency was 98 %. Intake exceeding the reference value for saturated fats was 86 %, and 72 % for simple carbohydrates. The consumption pattern was characterized by exceeding the recommendations for sugars (FCS = 1.29), milk and dairy products (FCS = 1.09), grains, roots, plantains and tubers (FCS = 1.04). Recommendations for the intake of fats (FCS = 0.70), meats, eggs, legumes, nuts, seeds (FCS = 0.49), fruits and vegetables (FCS = 0.41 were not met. Conclusions: The food intake pattern identified is far from meeting the national guidelines, limiting macro and micronutrient intake and contributing to the intergenerational malnutrition cycle. Additional research in the country is essential in order to identify other intake patterns and drive political action.

Objetivos: describir la prevalencia del riesgo de deficiencia o exceso en la ingesta de nutrientes y el patrón de consumo de alimentos de acuerdo con las recomendaciones establecidas por el Ministerio de Salud y Protección Social y el Instituto Colombiano de Bienestar Familiar. Materiales y métodos: se realizó un estudio transversal descriptivo en mujeres sanas que fueron atendidas en dos hospitales del oriente antoqueño, con seguridad alimentaria y nutricional (SAN) según la Escala Latinoamericana y Caribeña de Seguridad Alimentaria (ELCSA), en el primer trimestre de lactancia, evaluadas entre los años 2021 y 2022. La fuente de información fue la historia clínica. Se midieron las características sociodemográficas, clínicas, antropométricas y la ingesta dietética y de micronutrientes. Se empleó estadística descriptiva. Se presenta la prevalencia de déficit o exceso de ingesta calórica y el índice de relación de consumo (IRC). Se utilizaron los software EVINDI v5, PCSIDE v1.0, Stata 16.1 y Jasp 0.16.4. Resultados: se incluyeron 30 mujeres lactantes. La prevalencia de riesgo de deficiencia en la ingesta usual de energía fue 43 % y exceso 16 %; el riesgo de deficiencia proteica fue 98 %. El consumo superior al valor de referencia para grasa saturada fue 86 % y carbohidratos simples 72 %. El patrón de consumo se caracterizó por superar las recomendaciones para azúcares (IRC = 1,29), leche y derivados (IRC = 1,09), cereales, raíces, plátanos y tubérculos (IRC = 1,04). No cumplieron las recomendaciones en la ingesta de grasas (IRC = 0,70), carnes, huevos, leguminosas, frutos secos y semillas (IRC = 0,49), frutas y verduras (IRC = 0,41). Conclusiones: el patrón alimentario identificado dista de las guías nacionales, lo que limita el consumo de macro y micronutrientes, y contribuye al círculo intergeneracional de la malnutrición. Es fundamental realizar nuevas investigaciones en el país para identificar otros patrones de consumo e impulsar acciones de política al respecto.

Food and nutrient intake of adolescent women in Medellín, Colombia.

Nutritional imbalance in adolescent girls causes alterations in health, reproductive cycles, and fetal outcomes of future generations. To evaluate the dietary pattern and prevalence of inadequate nutrient intake, a 24-hour multi-step food recall was carried out among 793 adolescent women (14-20 years old) from Medellin, Colombia. Their dietary pattern was characterized by lower than recommended intakes of fruits and vegetables (CRI 0.4, AMD 0.2), dairy (CRI 0.5, AMD 0.2), and proteins (CRI 0.8, AMD 0.3), while starches (CRI 1.2, AMD 0.4), fats (CRI 1.1, AMD 0.6), and sugars (CRI 1.0, AMD 0.5) were at similar or higher levels than recommendations. A high risk of deficiency was found in the usual intake of energy (53.0%), protein (39.8%), calcium (98.9%), folates (85.7%), iron (74.4%), thiamine (44.3%), vitamin C (31.3%), zinc (28.3%), vitamin A (23.4%), cyanocobalamin (17.3%), and pyridoxine (10.9%). A low risk of deficiency was noted in usual fiber intake (0.5%), and a higher than recommended intake was noted in saturated fat (100.0%) and simple carbohydrates (68.8%). Anecdotally, a large proportion of respondents saw decreases in their food consumption during the COVID-19 pandemic. These results suggest an urgent need for nutrition education programs to emphasize the importance of adequate nutrition among adolescent women.

Maternal Diet May Modulate Breast Milk Microbiota-A Case Study in a Group of Colombian Women.

There is increasing evidence that the diet and nutritional status of women during pregnancy and lactation can modulate the microbiota of their milk and, therefore, the microbiota of the infant. An observational, descriptive, and cross-sectional study was carried out in a group of lactating women. Dietary intake during gestation and the first trimester of lactation was evaluated, and the microbiota was analyzed by 16S ribosomal RNA (rRNA) sequencing using the Illumina platform. Globally, Streptococcus spp. (32%), Staphylococcus spp. (17.3%), Corynebacterium spp. (5.1%) and Veillonella spp. (3.1%) were the predominant bacterial genera. The consumption of simple carbohydrates in gestation (rho = 0.55, p ≤ 0.01) and lactation (rho = 0.50, p ≤ 0.01) were positively correlated with Enterobacter spp. In lactation, a negative correlation was observed between the intake of simple carbohydrates and the genus Bifidobacterium spp. (rho = -0.51 p ≤ 0.01); furthermore, a positive correlation was identified between the intake of folic acid and Akkermansia spp. (rho = 0.47, p ≤ 0.01). Amplicon sequence variants (ASVs) associated with the delivery mode, employment relationship, the baby's gender, birth weight, the Body Mass Index (BMI) of the breastfeeding woman, and gestational weight gain were recovered as covariates in a linear mixed model. The results of this research showed that the maternal nutritional status and diet of women during gestation and lactation could modulate the microbiota of breast milk.

Exploring the potential of meeting adolescent girls' nutrient needs in urban Colombia using food-based recommendations.

During adolescence, many young people gain greater food choice agency but also become increasingly exposed and susceptible to environmental pressures that influence their food choices. This coincides with increased nutritional needs, especially for girls. In urban Colombia, adolescent diets are often high in undesirable foods and low in nutritious foods, contributing to overweight and micronutrient deficiencies. This study aimed to explore the potential of improving diet quality using food-based recommendations (FBRs) within the parameters of local food systems and adolescents' existing dietary patterns to inform context-specific programmatic responses to malnutrition. We applied linear programming analysis to dietary data from 13- to 20-year-old girls in Medellin to identify problem nutrients, local micronutrient sources, and promising FBRs. Iron and, to a lesser extent, calcium targets were difficult to meet using optimized diets based on local foods, especially for 13- to 17-year-olds. High habitual consumption of foods with excessive salt, fat, or sugar provided >5% of micronutrients in optimized diets. Otherwise, significant micronutrient sources included legumes, meat, dairy, bread, potatoes, and fruit. FBRs met targets for 10 micronutrients but only 32%-39% recommended nutrient intake for iron. FBRs, including occasionally consumed foods and supplements, met all intake targets for less cost, indicating a need to increase access to nutrient-dense products.

Mobilizing adolescents and young women to promote healthy diets in urban settings of Colombia and Vietnam: Lessons from two action-research programs.

Adolescent and young women face grave nutrition challenges, but limited evidence exists on solutions to improve their diets. Action-research was done over 3 years (2020-2022) in secondary cities of Colombia (Medellin) and Vietnam (Thai Nguyen) to identify nutrient deficits in adolescent and young women diets; elaborate food-based recommendations to improve their nutritional status using Optifood linear programming; and engage respondents in incorporating suggested recommendations to their diet using a Social Innovation Challenge approach. A total of 1001 respondents were interviewed in Vietnam, 793 in Colombia. The probability of nutrient inadequacy in both locations was highest for iron and calcium, followed by the risk of deficiency for several other vitamins and minerals. Social Innovation Challenge teams (11 in Vietnam, 9 in Colombia) were created and supported in developing solutions to improve diets and tackle those deficiencies. Awards and resources were transferred to the most promising solutions to enable their implementation. Pre/post measurements of the interventions' impact using the Global Diet Quality Score as outcome metric showed significant improvement in the diets of Challenge participants. After introducing a series of companion articles that offer detailed results on those various steps, this paper draws strategic lessons from an action-research perspective.

Effect of an action-research nutrition intervention on the Global Diet Quality Score of Colombian adolescents.

Strategies to address the nutritional needs of adolescent girls and young women often focus on supplementation. In this study, an action-research approach involving a nutrition education and entrepreneurship intervention was carried out among adolescent girls and young women in poor neighborhoods of Medellín, Colombia. The intervention group significantly increased its intake of several nutrients, including energy, protein, total fat, saturated fat, monounsaturated fat, polyunsaturated fat, cholesterol, dietary fiber, calcium, zinc, and vitamins A, B2, B3, B9, and C. A significant increase was observed in the intake of the Global Diet Quality Score (GDQS) healthy food groups (other fruits, other vegetables, legumes, high-fat dairy products), accompanied by a decrease in the consumption of some unhealthy food groups (sweets and ice creams). A multivariate regression controlling for age, socioeconomic status, occupation, Household Hunger Scale, mean probability of adequacy, physical activity, and body self-perception showed that the nutrition intervention improved the total GDQS by 33% in the intervention group-a substantial improvement notwithstanding the study group's precarious social and economic conditions. We conclude that nutrition education and entrepreneurship models based on this approach may improve the dietary profile of this population and reduce future pressures from nutrition-related chronic diseases.

Breastfeeding experiences from the perspective of the breastfeeding woman: qualitative study / Experiencias en lactancia materna, vivencia desde la mujer que amamanta: estudio cualitativo

Objectives: To understand the breastfeeding experience from the perspective of a group of women who breastfeed for the first time. Materials and Methods: Qualitative study from an ethnographic perspective, focusing on a group of women from the eastern region of the Department of Antioquia (Colombia). Intentional sampling until data saturation was used. The group included 16 first-time breastfeeding mothers aged 18 or older, with children under 24 months of age and who were breastfeeding or had breastfed exclusively for at least three months. Semi-structured interviews and participant observations were carried out. Data were analyzed by triangulation and open and axial coding. The results are presented in the form of category descriptions. Results: Four categories were identified in relation to the breastfeeding experience: exhaustion and pain dispelled by love, breastfeeding and the new order of things, emotions of a woman embodied in a mother, and breastfeeding as a social act. Conclusions: Protection of breastfeeding requires special attention to the woman as a subject beyond the act of breastfeeding, giving priority to her physical and emotional health as essential elements that must be kept in mind by healthcare professionals. Studies to assess the effects of creating support groups that foster the exchange of insights to help the breastfeeding woman are required.

Objetivos: comprender las experiencias sobre la lactancia materna desde la perspectiva de las mujeres, en un grupo de madres lactantes primerizas. Materiales y métodos: estudio cualitativo, bajo la perspectiva de etnografía, enfocado en un grupo de mujeres de la región oriente del departamento de Antioquia (Colombia). Por muestreo intencional y hasta la saturación de los datos se seleccionaron 16 mujeres lactantes primerizas, de 18 años o más, con hijos menores de 24 meses y que se encontraran amantando o hubiesen amantado de forma exclusiva al menos durante tres meses. Se realizaron entrevistas semiestructuradas y observación participante; el análisis de los datos se desarrolló por triangulación y codificación abierta y axial. Los resultados se presentan a través de la descripción de categorías. Resultados: se identificaron cuatro categorías frente a la experiencia del amamantamiento: el agotamiento y el dolor que se disipan con amor, la lactancia y el nuevo orden de las cosas, las emociones de una mujer en el cuerpo de una madre y  la lactancia: un acto social. Conclusiones: proteger la lactancia materna requiere poner especial cuidado a la mujer como sujeto, más allá del amamantamiento, dando prioridad a su salud física y emocional como elementos esenciales que deben ser considerados por los profesionales en salud. Se requieren estudios que evalúen los efectos de la creación de grupos de apoyo que propicien el intercambio de saberes para acompañar a la mujer lactante.

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.

Eating behavior in a group of overweight pregnant women in two municipalities of Antioquia, Colombia: qualitative study / Comportamiento frente a la alimentación en un grupo de gestantes con exceso de peso en dos poblaciones en Antioquia, Colombia: estudio cualitativo.

Objective: To describe eating behaviors in a group of overweight pregnant women. Material and methods: Qualitative study from the focused ethnography perspective that included pregnant women over the age of 18 years, with overweight or obesity or excess weight gain during pregnancy, who attended the pre-natal care program at two public healthcare institutions belonging to the government-subsidized regime under the General Social Security System in two municipalities of the Department of Antioquia (Colombia). Thirteen individual semi-structured and three group interviews were carried out. Analysis was based on triangulation and open and axial coding. Results: Overall, 22 pregnant women participated in the study. Five determinants of eating behavior in this population were found: low socioeconomic level that limits access to a variety of foods, social support network, health condition during previous pregnancies or during the current gestation, generic dietary and nutritional recommendations provided by healthcare staff and, finally, knowledge of the participants regarding diet and the implications of maternal overweight for the health of the mother and the child. Conclusion: It is imperative to provide dietary and nutritional education and care based on the particular characteristics that influence the adoption of changes in eating behaviors among overweight pregnant women; prenatal care professionals must be trained to promote standardized criteria and care that is tailored to the social reality of the pregnant woman.

Objetivo: describir el comportamiento, frente a la alimentación, de un grupo de gestantes con exceso de peso. Materiales y métodos: estudio cualitativo, desde la perspectiva de etnografía enfocada. Se incluyeron mujeres gestantes mayores de 18 años con sobrepeso u obesidad, o ganancia excesiva de peso en el embarazo, y que asistieron al programa de control prenatal de dos instituciones públicas de salud pertenecientes al régimen subsidiado por el Estado en el Sistema General de Seguridad Social, en dos municipios del departamento de Antioquia (Colombia). Se realizaron 13 entrevistas semiestructuradas individuales y tres entrevistas grupales. Análisis por triangulación y codificación abierta y axial. Resultados: participaron 22 mujeres gestantes. Se encontraron cinco factores que condicionan el comportamiento alimentario de esta población: el nivel socioeconómico bajo que limita el acceso a una alimentación variada, la red social de apoyo, el estado de salud en los embarazos previos o en la gestación actual, las recomendaciones genéricas brindadas por el personal de salud sobre alimentación y nutrición, y, por último, los conocimientos de las participantes sobre alimentación y las implicaciones del exceso de peso materno en la salud madre-hijo. Conclusión: es imperante que la atención y educación alimentaria y nutricional sean brindadas desde las particularidades que inciden en la adopción de cambios del comportamiento alimentario de las mujeres embarazadas con exceso de peso; los profesionales del control prenatal deben contar con capacitación que promueva la unificación de criterios y una atención adaptada a la realidad social de la gestante.

[Factors related to birth weight: a comparison of related factors between newborns of Spanish and Colombian immigrant women in Spain]. / Peso al nacer: una comparación de sus factores relacionados entre los recién nacidos de madres españolas y madres colombianas residentes en España.

The objective of this study is to establish differentials in birth weight (BW) and related factors, in term newborns (NB) of Spanish (SP) and Colombian (CO) immigrant mothers living in Spain, between 2001-2005. Data on the NB population of SP and CO mothers was retrieved from the National Statistical Bulletin of Birth in Spain. We analysed the association with BW (Low birth weight -LBW- insufficient weight -IW- macrosomia), by the nationality of the mother; taking into account variables such as the intergenesic interval, maternal age, number of live children, maternal occupation and sex of NB. The analysis was based on frequencies and the estimation of simple and adjusted odds ratios (OR) by means of logistic regression with 95% confidence intervals (95% CI). A higher prevalence of LBW was found in SP mothers (3.4%) than in their CO counterparts (2.1%). In SP mothers a higher risk of LBW (aOR 1.89, 950% CI 1.65- 2.16) and IW (aOR 1.49, 95% CI 1.51- 1.57) was observed. In CO mothers a higher percentage of macrosomia was found (8.0%). Also, a higher percentage of LBW was observed in female new borns (SP4.1%; CO 2.7%) as well as IW (PI (SP 25.6%; CO 19.6%) (p < 0.001). Mothers aged > 40 years and having 4 or more children were associated with LBW in both nationalities. As a conclusion, NB of Colombian mothers presented a lower prevalence of LBW and IW, which could be explained by the healthy migrant effect.

Height-based equations as screening tools for elevated blood pressure in the SAYCARE study.

This study evaluated the accuracy of four height-based equations: blood pressure to height ratio (BPHR), modified BPHR (MBPHR), new modified BPHR (NMBPHR), and height-based equations (HBE) for screening elevated BP in children and adolescents in the SAYCARE study. We measured height and BP of 829 children and adolescents from seven South American cities. Receiving operating curves were used to assess formula performance to diagnose elevated BP in comparison to the 2017 clinical guideline. Sensitivity, specificity, and positive and negative predictive values (PPV, NPV) were calculated for the four screening formulas. The diagnostic agreement was evaluated with the kappa coefficient. The HBE equation showed the maximum sensitivity (100%) in children, both for boys and girls, and showed the best performance results, with a very high NPV (>99%) and high PPV (>60%) except for female children (53.8%). In adolescents, the highest sensitivity (100%) was achieved with the NMBPHR for both sexes. Kappa coefficients indicated that HBE had the highest agreement with the gold standard diagnostic method (between 0.70 and 0.75), except for female children (0.57). Simplified methods are friendlier than the percentile gold standard tables. The HBE equation showed better performance than the other formulas in this Latin American pediatric population.

Factors associated with fetal macrosomia.

OBJECTIVE: To evaluate the clinical factors, as well as weight gain, in a group of pregnant women, associating them with fetal macrosomia in a public institution in Antioquia, Colombia, from 2010-2017. METHODS: A case-control study, using secondary information registries. Cases were defined using newborn weight of ≥ 4000g, while controls were defined as newborn weight between 3000-3999g. A proportion ratio (PR) was established to evaluate factors associated with macrosomia, and a generalized linear model (GLM) of Poisson regression with robust variance was used to evaluate the aspects that best explained macrosomia in the neonate. RESULTS: 122 pregnant women participated in the study, of which 611 were cases and 61 were controls. Of the participants, 44.3% had pre-pregnancy overweight and 48.4% had excess gestational weight gain. Statistically significant differences were found between the groups in the following variables: pre-pregnancy BMI (p = 0.004), gestational weight gain (p = 0.000), gestational diabetes (p = 0.000), and type of delivery (p = 0.004). According to the regression model, a macrosomic newborn is 3.5 times more likely in women with excessive gestational weight gain (95%CI 1.78-7.18) and twice more likely in women who have gestational diabetes (95%CI 1.51-2.76). Of women with pre-pregnancy excess weight, 63% had excess gestational weight gain. CONCLUSIONS: Within this cohort, pre-pregnancy BMI, excess weight gain in pregnancy, and the presence of gestational diabetes were associated with an increased risk of neonatal macrosomia. pre-pregnancy BMI and weight gain in pregnancy are modifiable risk factors that are responsive to nutrition interventions, which can minimize adverse perinatal outcomes.

Concentrations of Plasma Free Palmitoleic and Dihomo-Gamma Linoleic Fatty Acids Are Higher in Children with Abdominal Obesity.

Increased plasma free fatty acids (FFAs) are associated with cardiometabolic risk factors in adults with abdominal obesity (AO). However, this association remains controversial in children. This study analyzed plasma FFA concentration in children with and without AO. Twenty-nine children classified with AO were matched by age and sex with 29 non-obese individuals. Blood samples were collected after fasting for 10-12 h. Plasma concentration of glucose, insulin, triglycerides, total cholesterol, low-density lipoprotein cholesterol (LDL-C), and high-density lipoprotein cholesterol (HDL-C) were determined by automatized methods. FFAs were analyzed by gas chromatography. Children with and without AO had similar age (7.1 ± 2.6 vs. 7.2 ± 2.7 years; p > 0.05) but obese children showed higher (p < 0.05) body mass index (BMI) (+4.3 kg/m²), systolic blood pressure (+5.1 mmHg), and insulin (+27.8 pmol/L). There were no significant differences in plasma total FFA concentration between groups (1.02 ± 0.61 vs. 0.89 ± 0.37 mmol/L; p > 0.05). However, children with AO had higher palmitoleic acid (0.94 vs. 0.70 wt %; p < 0.05) and dihomo-gamma linoleic acid (DHGL) (2.76 vs. 2.07 wt %; p < 0.05). Palmitoleic and DHGL acids correlated (p < 0.05) with BMI (r = 0.397; r = 0.296, respectively) and with waist circumference (r = 0.380; r = 0.276, respectively). Palmitoleic acid correlated positively with systolic blood pressure (r = 0.386; p < 0.05) and negatively with HDL-C (-0.572; p < 0.01). In summary, children with AO have higher plasmatic concentrations of free palmitoleic and DHGL fatty acids, which correlate with cardiometabolic risk factors.

El patrón de consumo se caracterizó por superar las recomendaciones para azúcares (IRC = 1,29), leche y derivados (IRC = 1,09), cereales, raíces, plátanos y tubérculos (IRC = 1,04). No cumplieron las recomendaciones en la ingesta de grasas (IRC = 0,70), carnes, huevos, leguminosas, frutos secos y semillas (IRC = 0,49), frutas y verduras (IRC = 0,41). Conclusiones: El patrón alimentario identificado dista de las guías nacionales, lo que limita el consumo de macro y micronutrientes, y contribuye al círculo intergeneracional de la malnutrición. Es fundamental realizar nuevas investigaciones en el país para identificar otros patrones de consumo e impulsar acciones de política al respecto.

Objectives: To describe the prevalence of the risk of under or overnutrition and the food intake pattern vis á vis the recommendations of the Ministry of Health and Social Protection and the Colombian Family Welfare Institute. Material and methods: Descriptive cross-sectional study carried out in healthy women receiving care in two hospitals of eastern Antioquia, with food and nutrition security in accordance with the Latin American and Caribbean Food Security Scale (ELCSA), in the first trimester of breastfeeding, assessed between 2021 and 2022. The clinical record was used as the source of information. The sociodemographic, clinical, anthropometric characteristics, as well as dietary and micronutrient intake, were measured. Descriptive statistics were used. The prevalence of deficient or excessive energy intake and the food consumption score (FCS) are presented. The EVINDI v5, PC-SIDE v1.0, Stata 16.1 and Jasp 0.16.4 software packages were used. Results: Overall, 30 breastfeeding women were included. The prevalence of the risk of deficient energy intake was 43 %, while the risk of excessive intake was 16 % and the risk of protein deficiency was 98 %. Intake exceeding the reference value for saturated fats was 86 %, and 72 % for simple carbohydrates. The consumption pattern was characterized by exceeding the recommendations for sugars (FCS = 1.29), milk and dairy products (FCS = 1.09), grains, roots, plantains and tubers (FCS = 1.04). Recommendations for the intake of fats (FCS = 0.70), meats, eggs, legumes, nuts, seeds (FCS = 0.49), fruits and vegetables (FCS = 0.41) were not met. Conclusions: The food intake pattern identified is far from meeting the national guidelines, limiting macro and micronutrient intake and contributing to the intergenerational malnutrition cycle. Additional research in the country is essential in order to identify other intake patterns and drive political action.

Ingesta dietética y patrón alimentario de las mujeres en periodo de gestación y lactancia de los pueblos indígenas de Colombia. Problemática que requiere urgente atención

Objetivo: Analizar el patrón alimentario y el riesgo de deficiencia en la ingesta usual de energía y nutrientes de las mujeres gestantes y lactantes de algunos pueblos indígenas. Metodología: Estudio descriptivo transversal, con información del componente de ingesta dietética tomada del Estudio nacional de la situación alimentaria y nutricional de los pueblos indígenas de Colombia, realizado entre 2013 y 2019, que incluyó 1028 mujeres indígenas gestantes (319) y lactantes (709), de las regiones norte y sur del país. Resultados: Se encontró una proporción superior al 90 % (Desviación estándar = 0,04) de gestantes y lactantes con consumo inferior al recomendado de calorías (p= 0,038). Alrededor del 70 % de las gestantes y lactantes no consumió lácteos el día anterior a la encuesta, y 50 % no consumió frutas y verduras. Con respecto a los micronutrientes, se encontraron, en las gestantes y lactantes, altas prevalencias del riesgo de deficiencia en la ingesta de vitamina C (50,3 y 80,2 %), folatos (80,4 y 95,1 %), zinc (87,6 y 96,3 %), hierro (88,9 y 68,6 %) y calcio (87,5 y 98,5 %). Conclusión: El consumo de alimentos y nutrientes en las mujeres indígenas gestantes y lactantes es deficiente en nutrientes claves para mantener su estado de salud y proporcionar los nutrientes necesarios a su bebé, y su patrón alimentario se clasifica como no saludable.

Objective: To analyze the dietary pattern and deficiency risk in the usual energy and nutrient intake of pregnant and lactating women from some indigenous peoples. Methodology: Cross-sectional descriptive study, with information from the dietary intake component taken from the National Survey of the food and nutritional situation of indigenous peoples in Colombia, conducted between 2013 and 2019, which included 1,028 pregnant (319) and lactating (709) indigenous women from the northern and southern regions of the country. Results: A proportion higher than 90% (SD = 0.04) of pregnant and lactating women with lower than recommended calorie intake was found (p = 0.038). Around 70% of pregnant and lactating women had no any dairy products the day before the survey, and 50% did not eat fruits and vegetables. Regarding micronutrients, high prevalence of deficiency risk in the intake of vitamin C (50.3 and 80.2%), folate (80.4 and 95.1%), zinc (87.6 and 96.3%), iron (88.9 and 68.6%) and calcium (87.5 and 98.5%) was found in pregnant and lactating women. Conclusion: Food and nutrient intake in pregnant and lactating indigenous women is deficient in key nutrients to maintain their general health and provide the necessary nutrients to their babies. Their dietary pattern is considered unhealthy.

Objetivo: Analisar o padrão alimentar e o risco de deficiência na ingestão usual de energia e nutrientes das mulheres gestantes e lactantes de alguns povos indígenas. Metodologia: Estudo descritivo transversal, com informação do componente de ingesta dietética tirada do Estudo nacional da situação alimentar e nutricional dos povos indígenas da Colômbia, realizado entre 2013 e 2019, que incluiu 1028 mulheres indígenas gestantes (319) e lactantes (709) das regiões norte e sul do país. Resultados: Encontrou-se uma proporção superior a 90% (Desvio-padrão = 0,04) de gestantes e lactantes com consumo inferior ao recomendado em calorias (p = 0,038).

Conclusão: O consumo de alimentos e nutrientes nas mulheres indígenas gestantes e lactantes é deficiente em nutrientes-chave para manter seu estado de saúde e proporcionar os nutrientes necessários para o bebê; seu padrão alimentar classifica-se como não saudável.

Factores asociados al estado nutricional en un grupo de mujeres lactantes de Antioquia, Colombia

Objetivo: Evaluar los factores asociados al estado nutricional de un grupo de mujeres en periodo de lactancia materna del departamento de Antioquia. Metodología: Estudio analítico transversal de fuentes secundarias, con información de 102 madres lactantes que viven en Antioquia, de una encuesta realizada en 2019. Se utilizó un modelo multivariado de regresión de Poisson, para ajustar la razón de prevalencias con el exceso de peso y la anemia; y un análisis de correspondencia múltiple, para evaluar los factores asociados al estado nutricional de las mujeres lactantes. Resultados: Se halló asociación positiva con el grupo de edad, la retención de peso excesiva en el posparto y el nivel socioeconómico. En el análisis de correspondencia múltiple, las mujeres constituyeron tres conglomerados: con mejores condiciones socioeconómicas y nutricionales; con mayor vulnerabilidad socioeconómica y malnutrición por déficit, y con vulnerabilidad socioeconómica y exceso de peso. Conclusiones: Las mujeres asumen la lactancia en medio de vulnerabilidad social y económica, inseguridad alimentaria, exceso de peso, anemia y riesgo de déficit de micronutrientes. Es necesario documentar el estado nutricional de las mujeres en etapa de lactancia, por medio de su inclusión en las encuestas poblaciones y, de acuerdo con ello, generar lineamientos de atención durante esta etapa.

Objective: To assess the factors associated with the nutritional status of a group of breastfeeding women in the department of Antioquia. Methodology: Analytical cross-sectional study using secondary sources, with data from 102 nursing mothers living in Antioquia based on a 2019 survey. We used a multivariate Poisson regression model to adjust the prevalence ratio with overweight and anemia, along with multiple correspondence analysis to evaluate the factors associated with the nutritional status of the breastfeeding women. Results: There was a positive association with age group, excessive postpartum weight retention, and socioeconomic status. The women represented three clusters in the multiple correspondence analysis: better socioeconomic and nutritional conditions; greater socioeconomic vulnerability and micronutrient malnutrition; and socioeconomic vulnerability and overweight. Conclusions: Women undertake breastfeeding amid social and economic vulnerability, food insecurity, overweight, anemia, and the risk of micronutrient deficiencies. It is necessary to document the nutritional status of breastfeeding women by including them in population surveys and, accordingly, by developing guidelines for care during this stage

Objetivo: Avaliar os fatores associados ao estado nutricional de um grupo de mulheres em período de aleitamento materno do departamento de Antioquia. Metodologia: Estudo analítico transversal de fontes secundárias, com informação de 102 mães lactantes que moram em Antioquia, de uma enquete realizada em 2019. Utilizou-se um método multivariado de regressão de Poisson, para ajustar a razão de prevalências com o excesso de peso e a anemia; e uma análise de correspondência múltipla, para avaliar os fatores associados com o estado nutricional das mulheres lactantes. Resultados: Achou-se associação positiva com o grupo de idade, a retenção de peso excessiva no pósparto e o nível socioeconômico. Na análise de correspondência múltipla, as mulheres constituíram três grupos: com melhores condições socioeconômicas e nutricionais; com maior vulnerabilidade socioeconômica e má nutrição por déficit; e, com vulnerabilidade socioeconômica e excesso de peso. Conclusões: As mulheres assumem o aleitamento no meio da vulnerabilidade social e econômica, insegurança alimentar, excesso de peso, anemia e risco de déficit de micronutrientes. É necessário documentar o estado nutricional das mulheres em etapa de aleitamento, por meio de sua inclusão nas enquetes populacionais e, em concordância com isso, gerar diretrizes de atenção durante essa etapa.
