Equations for Prediction of Body Adiposity in Patients With Chronic Kidney Disease Undergoing Hemodialysis.

OBJECTIVES: The prevalence of obesity in the population has increased and excess body adiposity is one of the main nutritional disorders in patients with chronic kidney disease (CKD) on hemodialysis (HD). The objective of this study was to develop equations using anthropometric measurements to predict the total and abdominal body adiposity of patients with CKD on HD. METHODS: This is a cross-sectional study evaluating 323 patients with CKD on HD in city in northeastern Brazil. Measurements and anthropometric indicators were correlated with percentage of body fat (%BF) and visceral fat (VF, in kg) measured by dual energy X-ray absorptiometry. Multiple linear regression models based on different combinations of anthropometric measurements were adjusted to develop the equations, with subsequent cross-validation. RESULTS: Of the 323 patients, 62.2% were male and 46.5% were aged between 40 and 59 years. The equation selected to estimate %BF included weight, height, waist and hip circumferences, and triceps and suprailiac skin folds, presenting high predictive capacity (R2 = 0.771). The equation selected to estimate VF included weight, height, waist circumference, hip circumference, and sum of skin folds (R22 = 0.796). CONCLUSIONS: The proposed equations efficiently predicted the %BF and VF (kg) of patients with CKD on HD, thereby serving as viable indicators in clinical practice.

Clinical-epidemiological characteristics and survival of cases of severe acute respiratory syndrome (SARS) due to COVID-19, according to the COVID-19 vaccination schedule in Brazil, 2021-2022: a prospective study.

OBJECTIVE: To analyze the clinical and sociodemographic characteristics and survival of individuals with severe acute respiratory syndrome due to COVID-19 according to the COVID-19 vaccination schedule, Brazil, 2021-2022. METHODS: This was a cohort study based on data from the Influenza Epidemiological Surveillance Information System; the Kaplan-Meier and Survival Tree methods were used to analyze survival. RESULTS: Among the 559,866 hospitalized cases, a higher proportion of vaccinated individuals was found among female (15.0%), elderly people aged ≥ 80 (34.5%), people from the Southeast region (15.7%), those who did not undergo respiratory support (21.2%) and those who did progress to death (15.2%); the survival curve showed that risk of death for unvaccinated individuals was higher in all age groups (p-value < 0.001); elderly people aged ≥ 80, who did not undergo mechanical ventilation and who had a booster dose had lower risk when compared to their peers who had two doses or were unvaccinated (hazard ratio = 0.64; 95%CI 0.62;0.67). CONCLUSION: Lowest risk of death was found in vaccinated individuals, especially those who had two doses or a booster dose as well. MAIN RESULTS: Prevalence was found to be high among unvaccinated individuals. Risk of death was lower among those vaccinated with a booster dose, compared to those not vaccinated, in all age groups analyzed. IMPLICATIONS FOR SERVICES: The number of hospitalizations of unvaccinated individuals with severe acute respiratory syndrome was high, which increases the demand for health services to care for these individuals. PERSPECTIVES: It is necessary to promote widespread vaccination of the entire population of Brazil, in addition to the regular provision of booster doses for the different population groups.

Proposition of an Energy Intake Estimating Scale through Item Response Theory.

BACKGROUND: Traditional methods for assessing individual energy consumption often involve lengthy and intricate procedures. This study aims to introduce an Energy Consumption Estimation Scale, utilizing Item Response Theory (IRT) for adolescents aged 18-19 years. METHODS: This psychometric investigation applies IRT to 93 items extracted from a validated food frequency questionnaire. The study encompasses a representative sample of 2515 adolescents from the São Luís birth cohort in Brazil. The latent trait, energy intake, is derived using IRT and subsequently validated through hierarchical multiple linear regression modeling. Significance was established at p < 0.05. RESULTS: A Samejima's model was successfully fitted (CFI and TLI > 0.9 and RMSEA < 0.08), effectively capturing variations across all energy consumption levels. Factors associated with the latent trait demonstrate consistent behavioral patterns. Adolescents with higher energy intake exhibited increased consumption of dairy products, artificially sweetened beverages, and seasonal fruits and vegetables. CONCLUSIONS: The proposed Energy Consumption Estimation Scale demonstrates a reliable measurement of energy intake and serves as a practical and concise alternative for assessing energy consumption among adolescents. These findings suggest the potential for adapting similar models for different age groups and incorporating diverse food items based on the obtained results.

Assessment of the Brazilian Version of the Epworth Sleepiness Scale Using Item Response Theory: A Psychometric Study.

There seems to be a consensus that adolescents worldwide are not getting enough sleep. This study aimed to evaluate the psychometric properties of the Epworth Sleepiness Scale (ESS) in adolescents using the item response theory. A psychometric study was conducted with 2206 adolescents aged 18 and 19 years in the city of São Luís, Maranhão, Brazil. The dimensionality of the ESS was assessed by principal component analysis. A Samejima's graded response model (SGRM) was fitted to it. The findings of this study showed a good internal consistency and the unidimensionality of the ESS. Considering the latent trait continuum, we obtained three levels, with anchor items. For the item 'Sitting still in a public place', the adolescents presented a small possibility of dozing in level 1, and a medium and great possibility in level 2. The item 'Sitting around talking to someone' presented small, medium, and great possibilities of dozing in level 3. The ESS with five items showed satisfactory psychometric properties. In addition, the results from the SGRM showed that adolescents with high levels of sleepiness are likely to nod off or sleep sitting up while talking to someone. This study allows us to understand excessive daytime sleepiness in adolescents.

Temporal trends and projections of caesarean sections in Brazil, its administrative macro-regions, and federative units. / Tendências temporais e projeções de cesariana no Brasil, macrorregiões administrativas e unidades federativas.

Trend studies on the model of birth in Brazil show a scenario of successive linear increases in cesarean rates. However, they ignore possible changes in the temporal evolution of this delivery modality. Thus, this study aimed to evaluate possible inflection points in cesarean rates in Brazil, its macro-regions, and federated units, as well as to estimate projections for 2030. A time series with information on cesarean sections from 1994 to 2019 from the SUS Department of Informatics was used. Autoregressive integrated moving average and joinpoint regression models were used to obtain cesarean rate projections and trends, respectively. Caesarean rates showed a significant upward trend over the 26 study years at all levels of aggregation. On the other hand, when considering the formation of segments, a stabilization trend was observed both in the country and in the South and Midwest regions, starting in 2012. Rates tended to increase in North and Northeast and significantly decrease in Southeast. Projections show that in 2030, 57.4% of births in Brazil will be cesarean, with rates higher than 70% in Southeast and South regions.

Os estudos de tendência sobre a via de nascimento no Brasil têm revelado um cenário de sucessivos aumentos lineares nas proporções de cesariana. Entretanto, a possibilidade de mudanças na evolução temporal da via cirúrgica não tem sido considerada. Dessa forma, objetivou-se verificar possíveis pontos de inflexão na proporção de cesarianas no Brasil, macrorregiões e unidades federativas, bem como estimar suas projeções para o ano de 2030. Utilizou-se a série temporal com as cesarianas notificadas no Departamento de Informática do SUS no período de 1994 a 2019. Foram utilizados modelos autorregressivos integrados de médias móveis e de regressão joinpoint para obtenção de projeções e de tendências das proporções de cesariana, respectivamente. As proporções de cesarianas apresentaram tendência significativa de aumento ao longo dos 26 anos de estudo em todos os níveis de agregação. Por outro lado, quando se considera a formação de segmentos, observa-se tendência de estabilização no país e nas regiões Sul e Centro-Oeste, a partir de 2012. Norte e Nordeste apresentaram tendência de aumento e o Sudeste, de queda significativa. Projeções indicam que no ano de 2030, 57,4% dos nascimentos no país ocorrerão por via cirúrgica e que nas regiões Sudeste e Sul, serão observadas proporções superiores a 70%.

Racial and regional inequality in the temporal trend of stunting and excess weight in Brazilian children under five years of age. / Desigualdade racial e regional na tendência temporal do déficit de estatura e excesso de peso de crianças brasileiras menores de cinco anos.

OBJECTIVE: To analyze the occurrence of racial and regional inequality in the temporal trend of the prevalence of stunting and overweight in Brazilian children under five years of age over the years 2008-2018. METHODS: An ecological time-series study with data from the Food and Nutrition Surveillance System on the prevalence of stunting and overweight in children under five years old according to race/skin color, region, and year. To assess differences between median prevalence per year of outcomes, the Kruskal-Wallis test was performed. Linear regression analyses were proposed to assess trends in the prevalence of outcomes over the years. RESULTS: In Brazil, black children tended to be overweight (ß=4.611; p=0.042). Among black children, there was an increase over the years in stunting in the Southeast (ß=3.960; p=0.014) and a decrease in the South (ß=-4.654; p=0.022). In Brazil and in most regions, the median prevalence of stunting was higher in black children than in white ones (12.86 vs. 11.54%, p<0.001). In the Southeast and South, black children also had the highest prevalence of overweight (15.48 and 15.99%, respectively). CONCLUSION: Children from less developed regions of Brazil and of black skin color/race were more vulnerable to a double burden of malnutrition.

OBJETIVO: Analisar a ocorrência de desigualdade racial e regional na tendência temporal das prevalências de déficit de estatura e excesso de peso de crianças brasileiras menores de cinco anos ao longo dos anos de 2008­2018. MÉTODOS: Estudo ecológico de série temporal com dados do Sistema de Vigilância Alimentar e Nutricional das prevalências de déficit de estatura e excesso de peso em crianças menores de 5 anos de acordo com raça/cor, região e ano. Para avaliar diferenças entre prevalências medianas por ano dos desfechos, realizou-se teste de Kruskal-Wallis. Análises de regressão linear foram propostas para avaliar tendências das prevalências dos desfechos ao longo dos anos. RESULTADOS: No Brasil, as crianças pretas apresentaram tendência de crescimento do excesso de peso (ß=4,611; p=0,042). Entre as crianças pretas, houve aumento ao longo dos anos do déficit de estatura no Sudeste (ß=3,960; p=0,014) e queda no Sul (ß=-4,654; p=0,022). No Brasil e na maioria das regiões, a prevalência mediana do déficit de estatura foi maior nas crianças pretas do que nas brancas (12,86 vs. 11,54%, p<0,001). No Sudeste e Sul, as crianças pretas também apresentaram as maiores prevalências de excesso de peso (15,48 e 15,99%, respectivamente). CONCLUSÃO: Crianças de regiões menos desenvolvidas do Brasil e pretas apresentaram maior vulnerabilidade para dupla carga de má nutrição.

Prevalence of metabolic syndrome in adolescents based on three diagnostic definitions: a cross-sectional study

ABSTRACT Objective: There is no consensus as to the best criterion for the evaluation of metabolic syndrome (MS), impairing the estimation of its prevalence. This study aims to compare MS estimates using three recommended definitions for adolescents based on a cross-sectional study nested in the Consortium of Brazilian Birth Cohorts in São Luís, Maranhão. Subjects and methods: A total of 2,515 adolescents aged between 18 and 19 years were evaluated. The criteria of International Diabetes Federation (IDF) and National Cholesterol Education Program Panel III (NCEP-ATP) modified by Cook and cols. (2003) and De Ferranti and cols. (2004) defined SM. To compare the estimates of MS prevalence, the chi-square, Fisher's exact and Cohen's Kappa index tests were used. Results: Among the 2,064 participants evaluated in the final sample. The prevalence of MS ranged from 4.2% (95% CI: 3.3-5.1) to 10.2% (95% CI: 8.8-11.4). When comparing the estimates of MS prevalence in the total sample and by sex, a statistically significant difference was observed. The agreement between the criteria ranged from 0.42 (CI 95%: 0.35-0.49) to 0.55 (CI 95%: 0.48-0.62) in the total sample, 0.33 (CI 95%: 0.24-0.42) to 0.59 (95%CI: 0.47-0.71) among boys and 0.39 (95% CI: 0.26-0.52) to 0.54 (95% CI: 0.44-0.64) among girls. Conclusion: Different criteria provide different estimates for the prevalence of MS in adolescents, reflecting the importance of establishing a consensus.

Desigualdade de raça/cor e estado nutricional de crianças beneficiárias do Programa Bolsa Família no Maranhão e no Brasil / Race/color inequality and nutritional status of children beneficiary from the Bolsa FamíliaProgram in the state of Maranhão and in Brazil

Introdução: Segmentos populacionais não-brancos sofrem reconhecida desvantagem socioeconômica, além do componente da desigualdade racial que intensifica a vulnerabilidade desses grupos. Objetivo: Analisar o estado nutricional de acordo com raça/cor e região geográfica entre crianças maranhenses e brasileiras beneficiárias do PBF. Métodos: Estudo descritivo com dados do estado nutricional de crianças menores de cinco anos beneficiárias do PBF acompanhadas pelo Sistema de Vigilância Alimentar e Nutricional em 2017 no Brasil. Resultados: A raça/cor indígena apresentou as maiores prevalências de desnutrição em todas as regiões avaliadas e as menores prevalências de excesso de peso, exceto na Região Sul. As raças/cor preta e amarela apresentaram as maiores prevalências de desnutrição conseguintes. As raças/cor amarela e branca também figuraram com elevadas prevalências de excesso de peso. O Maranhão obteve prevalências de desnutrição e excesso de peso superiores e inferiores, respectivamente, ao Brasil em todas as raças/cor. Conclusões: Os resultados deste estudo apontam a existência de desigualdade de raça/cor no estado nutricional das crianças avaliadas. Destaca-se a maior vulnerabilidade das crianças indígenas à desnutrição.

Introduction: Non-white population segments suffer recognized socioeconomic disadvantage, in addition to the racial inequality component that intensifies the vulnerability of these groups. Objective: to analyze the nutritional status according to race/color and geographic region among children from Maranhão and Brazilian beneficiaries of the PBF. Methods: Descriptive study with data on the nutritional status of children under five years of age who are beneficiaries of the PBF followed by the Food and Nutritional Surveillance System in 2017 in Brazil. Results: The indigenous race/color had the highest prevalence of malnutrition in all regions evaluated and the lowest prevalence of overweight, except in the South region. The black and yellow races/color had the highest prevalence of malnutrition as a result. The yellow and white races/color also featured high prevalence of overweight. Maranhão had higher and lower prevalences of malnutrition and overweight, respectively, than Brazil in all races/color. Conclusions: The results of this study point to the existence of racial/color inequality in the nutritional status of the evaluated children. The greater vulnerability of indigenous children to malnutrition is highlighted.

Fatores associados ao elevado percentual de gordura corporal em indivíduos fisicamente ativos / Factors associated with the high body fat percentage in physically active individuals

Introdução: O exercício físico é praticado com diversos objetivos, destacando-se a promoção na mudança da composição corporal, com a redução de gordura e aumento de massa magra. Assim, compreender os fatores que podem estar associados nesta modificação se torna relevante. Objetivo: Analisar os fatores demográficos, estilo de vida, bioquímico, alimentares e de treinamento associados ao percentual de gordura corporal em praticantes de exercício físico em academias. Materiais e Métodos: Estudo transversal com 143 praticantes de exercícios físicos saudáveis, de ambos os sexos. Características sociodemográficas e estilo de vida foram obtidas através da aplicação de questionário. O consumo alimentar foi obtido através de registros alimentares de 24h, considerando as médias de três dias. A composição corporal foi avaliada por meio de avaliação antropométrica e pelo teste de bioimpedância elétrica. A análise estatística contemplou o teste de Shapiro Wilk para verificação da normalidade; o qui-quadrado e exato de Fisher foram usados para avaliar a associação entre as variáveis categóricas e a variável resposta e os testes de Mann-Whitney e t de Student para as contínuas. A regressão de Poisson com variância robusta foi usada para determinar as associações entre variáveis estudadas. O software Stata versão 14.0 foi usado para análise estatística, tendo sido adotado o valor de p <0,05. Resultados: A prevalência de gordura corporal elevada foi de 49,3% nos homens e 79,2% nas mulheres. Os fatores associados foram o maior consumo de proteína e fibras nas mulheres e a concentração de monócitos nos homens. Conclusão: Apesar de se tratar de público fisicamente ativo, observou-se elevado percentual de gordura entre os participantes do estudo e os fatores associados reforçam o caráter multietiológico deste indicador. (AU)

Introduction: Physical exercise is practiced with several objectives, especially the promotion of changes in body composition, with fat reduction and increase in lean mass. Thus, understanding the factors that may be associated with this modification becomes relevant. Objective: To analyze demographic, lifestyle, biochemical, dietary, and training factors associated with the percentage of body fat in practitioners of physical exercise in gyms. Materials and Methods: Cross-sectional study with 143 healthy physical exercise practitioners, of both sexes. Sociodemographic characteristics and lifestyle were obtained through the application of a questionnaire. Food consumption was obtained through 24-hour food records, considering the averages of three days. Body composition was assessed using anthropometric assessment and the electrical bioimpedance test. The statistical analysis included the Shapiro Wilk test to verify normality, the chi-square and Fisher's exact test were used to assess the association between categorical variables and the response variable and the Mann-Whitney and Student t tests for the continuous variables. Poisson regression with robust variance was used to determine the associations between studied variables. Stata software version 14.0 was used for statistical analysis and a value of p <0.05 was adopted. Results: The prevalence of high body fat was 49.3% in men and 79.2% in women. The associated factors were the higher consumption of protein and fibers in women and the concentration of monocytes in men. Conclusion: Despite being a physically active public, a high percentage of fat was observed among the study participants and the associated factors reinforce the multi-etiological character of this indicator.

Malnutrition and associated factors among quilombola children under 60 months of age in two cities of the state of Maranhão, Brazil. / Desnutrição e fatores associados em crianças quilombolas menores de 60 meses em dois municípios do estado do Maranhão, Brasil.

OBJECTIVE: To evaluate the prevalence of malnutrition in children under 60 months of age living in quilombo remnant communities of two municipalities in the state of Maranhão and their associated factors. METHODS: This is a cross-sectional study conducted with a sample of 372 children in August 2015. Socioeconomic, demographic, maternal and child information were collected. The anthropometry followed the one proposed by the World Health Organization. Height-for-age and weight-for-height rates were calculated using Anthro software version 3.2.2. Poisson regression was performed with a robust variance for the association of malnutrition with the studied variables, using Stata software version 14.0. RESULTS: Child malnutrition was high for height-for-age (15.1%) and weight-for-height (7%). Children whose mothers had a short height (< 1.497 m) were more likely to have height-for-age deficits (p < 0.05). No variables were statistically associated with low weight-for-height. CONCLUSION: Child malnutrition persists as a public health problem in vulnerable regions, and maternal factors such as low maternal height may explain the short stature of the children. The need for actions to address this nutritional deviation is pointed out.

O objetivo deste artigo é avaliar a prevalência de desnutrição em crianças menores de 60 meses residentes em comunidades remanescentes de quilombos de dois municípios do estado do Maranhão e seus fatores associados. Estudo transversal com amostra de 372 crianças realizado em agosto de 2015. Foram coletadas informações socioeconômicas, demográficas, maternas e das crianças. A antropometria seguiu o proposto pela Organização Mundial da Saúde. Foram calculados os índices estatura para idade e peso para estatura utilizando o software Anthro versão 3.2.2. Foi realizada regressão de Poisson com variância robusta para a associação da desnutrição com as variáveis estudadas, utilizando o software Stata versão 14.0. A desnutrição em crianças foi elevada segundo a estatura-por-idade (15,1%) e peso-para-estatura (7%). Crianças cujas mães possuíam baixa estatura (< 1,497 m) apresentaram mais chances de possuírem déficit de estatura-para-idade (p < 0,05). Nenhuma variável se associou estatisticamente ao baixo peso-para-estatura. A desnutrição infantil persiste como problema de saúde pública em regiões vulneráveis e os fatores maternos como a baixa estatura materna podem explicar a baixa estatura dos filhos. Aponta-se para a necessidade de ações de enfrentamento deste desvio nutricional.

Abstract Objective: To evaluate the prevalence of malnutrition in children under 60 months of age living in quilombo remnant communities of two municipalities in the state of Maranhão and their associated factors. Methods: This is a cross-sectional study conducted with a sample of 372 children in August 2015. Socioeconomic, demographic, maternal and child information were collected. The anthropometry followed the one proposed by the World Health Organization. Height-for-age and weight-for-height rates were calculated using Anthro software version 3.2.2. Poisson regression was performed with a robust variance for the association of malnutrition with the studied variables, using Stata software version 14.0. Results: Child malnutrition was high for height-for-age (15.1%) and weight-for-height (7%). Children whose mothers had a short height (< 1.497 m) were more likely to have height-for-age deficits (p < 0.05). No variables were statistically associated with low weight-for-height. Conclusion: Child malnutrition persists as a public health problem in vulnerable regions, and maternal factors such as low maternal height may explain the short stature of the children. The need for actions to address this nutritional deviation is pointed out.
