Physical growth curves of indigenous Xavante children in Central Brazil: results from a longitudinal study (2009–2012)

Abstract Background: The nutritional profile of Indigenous children in Brazil is comparable to those observed in some of the least developed regions of the world. Aim: Weight and height growth curves were characterised based on longitudinal data from a local Indigenous population experiencing the double burden of child under-nutrition and adult obesity. Subjects and methods: Anthropometric data were collected in six waves from 2009–2011 for children <10 in two proximate Xavante villages in Central Brazil. Prevalence rates for stunting, wasting and thinness were calculated using WHO references. Weight and height data were adjusted for generalised additive mixed models to generate growth curves. Results: Prevalence rates of stunting and wasting were high, but cases of thinness and excess weight were negligible. Weight and height began close to WHO medians, but fell substantially before 12 months. Boys but not girls were able to catch-up in weight before age 10. From 3–10 years, height for both sexes remained between −2 and 0 z-scores. Conclusion: Impaired Xavante growth before 1 year followed by inconsistent recovery before 10 years reflects health and wellbeing disparities with regard to the Brazilian national population and a complex epidemiology of growth involving rapid nutritional change.

Estado nutricional e autopercepção da imagem corporal de idosas de uma Universidade Aberta da Terceira Idade

The study aimed to estimate the association between nutritional status and body self-image dissatisfaction in elderly women attending the Food, Nutrition and Elderly Course at UnATI/UERJ. A cross-sectional study was conducted, with semi-structured interviews with all elderly (≥60 years), obtaining information regarding body image perception (scale of nine Stunkard silhouettes), socioeconomic, health and demographic indicators, and BMI. The data were analyzed using the Chi-square test and linear regression (significance level=5%). It was found that 50.0% had normal weight; 6.0% were in the category of underweight; and 44.0% were overweight (p=0.425). Regarding the perception of body image, 74.0% (n=37;p=0.0049) were dissatisfied with the body, mainly by excess (89.2%). Of those who expressed dissatisfaction with low weight, most were eutrophic. On the other hand, between the ones dissatisfied by excess, 30.2% are not overweight. Silhouettes 2 and 3 were identified as ideal for half of the respondents, although the self-perception of 62.0% of the elderly had been the silhouettes 4 and 5. The belly and limbs, especially lower body parts are the least liked by the older (78.0%). The silhouettes rating scale of the actual image increases as BMI (p<0.001). The opposite occurs regarding the ideal image (p<0.001). Individuals with high BMI tend to be more dissatisfied with their body image and this may be related to weight excess. This fact deserves deeper understanding of the determinants and meanings of this complex relationship dissatisfaction between body, beauty, health and aging.

High cholesterol dietary intake during pregnancy is associated with large for gestational age in a sample of low-income women of Rio de Janeiro, Brazil.

The association between the quality of maternal dietary fat intake during pregnancy and the infants birthweight (BW) remains controversial. Our goal was to investigate the association between maternal dietary fat intake during pregnancy and the rate of large for gestational age (LGA) newborns. This study employed a cross-sectional analysis of 297 pairs of mothers/children attending a public maternity at Rio de Janeiro, Brazil. BW for gestational age according to the Intergrowth 21st was defined as follows: adequate for gestational age (AGA ≤ 90th percentile) and LGA (>90th percentile). The statistical analysis was a Poisson regression with robust estimations of the standard errors. Maternal dietary fat intake variables comprised lipids (% total energy); saturated (mg/1000 kcal), monounsaturated (mg/1000 kcal) and polyunsaturated (mg/1000 kcal) fats; and cholesterol (mg/1000 kcal), all of which were obtained with a Food Frequency Questionnaire. The mean BW was 3338 g (SD = 446.9), and the rate of LGA newborns was 13.1%. The mean maternal total energy intake was 2880 kcal (SD = 1074), cholesterol was 154.3 mg/1000 kcal (SD = 68.1) and monounsaturated fat was 6.9 mg/1000 kcal (SD = 2). Mothers of LGA newborns reported higher cholesterol dietary intake (195.8 vs. 148 mg/1000 kcal; P < 0.001), pre-pregnancy body mass index (25.1 vs. 23.5 kg/m2 ; P = 0.026) when compared with mothers of AGA newborns. Women with cholesterol intake within the fourth quartile were 2.48 (95% confidence interval: 1.31-4.66) times more likely to have an LGA infant compared with those in the 1-3 quartiles. Dietary intake of cholesterol during pregnancy influences LGA even after adjusting for other confounders.

Avaliação nutricional de idosos: desafios da atualidade

The majority of the public health problems in Brazil are related to nutritional status. Population aging is a reality and presents great challenges, especially for the health sector. Since nutrition plays a role in modulating the aging process, in the etiology of diseases and in the functional declines associated with aging, evaluation and nutritional monitoring of the elderly are necessary for proper care and planning of health promotion strategies. In this context, the present study aimed to reflect on the monitoring methods and proposed indicators of nutritional assessment of the elderly. It presents a summary of Ministry of Health recommendations which guide the care and nutritional assessment provided to the elderly by the National Health Service (SUS). The recommended procedures for the diagnosis and monitoring of the nutritional status of the elderly, though suggesting an increasing importance of monitoring food consumption indicators, end up emphasizing the use of anthropometric measures, especially the body mass index. The incorporation of other indicators in monitoring the elderly demonstrates progress in the recognition of the fundamental issues that need to be incorporated into professional practice and routine primary care. However, these indicators must be used by the professional as part of a critical, team-based approach, it being understood that no single indicator will meet the needs of all the elements of nutritional assessment, especially when it comes to the elderly.

Selection of quality indicators for nutritional therapy in pediatrics: a cross-sectional study conducted in Brazil

Background Quality indicators for nutritional therapy (QINT) are important in assessing care and monitoring of resources. Among the 30 indicators proposed by International Life Sciences Institute, Brazil, there is still no evaluation of the most pertinent for Pediatrics. Objective To list the 10 main quality indicators for nutritional therapies (QINTs) for Pediatrics. Methods This was a two-phase cross-sectional study. Firstly, a questionnaire was answered by physicians, nutritionists, nurses, and pharmacists, all with having experience in nutritional therapy (NT) with Pediatrics, in Rio de Janeiro, Brazil. Participants assessed four attributes of QINT by using the Likert scale. A Top 10 ranked QINT list for Pediatrics was established. To verify the consistency of the questionnaire, Cronbach’s Alpha coefficient was calculated. Secondly, the opinions of the participants on the results that were obtained were requested and the percentages of the positive responses were calculated. Results A total of 33 professionals participated in the first phase and 92% (n = 23 of 25) in the second phase approved the results of the selected indicators. Among the Top 10 QINTs, the three main ones were: #1: “Frequency of diarrhea in those patients on enteral nutrition” (mean = 13.194; α = 0.827); #2: “Frequency of dietary nutritional prescriptions upon the hospital discharge of the NT patients” (mean = 12.871; α = 0.822); #3: “Frequency of the NT patients who recovered their oral intake” (mean = 12.839; α = 0.859). Conclusion When considering the consistency and the concordance that were obtained, it can be suggested that the list of Top 10 QINTs as proposed in this study will help in the evaluation of NT quality indicators for Pediatrics.

Sleep duration of 24 h is associated with birth weight in nulli- but not multiparous women.

OBJECTIVES This study aimed to evaluate the association between nightly, napping, and 24-h sleep duration throughout pregnancy and birth weight z-score among nulli- and multiparous women. METHODS Nightly,napping, and 24-h sleep duration and birth weight z-score (calculated on thebasis of the International Fetal and Newborn Growth Consortium for the 21st century standards) were studied in a cohort of 176 pregnant women from Brazil. Linear mixed-effect analyses were performed to assess the longitudinal evolution of sleep duration and the best unbiased linear predictors of the random coefficients were estimated. The best unbiased linear predictor estimates of sleep duration intercept and slope were included in the linear regression models with birth weight z-score as the outcome. RESULTS The mean hours of nightly sleep decreased during pregnancy in nulliparous women (β = -0.55; 95% confidence interval [CI], -0.83 to -0.27) but the decrease was not statistically significant in multiparous women (β = -0.19; 95% CI, -0.30 to 0.01). Twenty-four hour sleep duration decreased during pregnancy in both multiparous (β = -0.50; 95% CI, -0.76 to -0.25) and nulliparous women (β = 0.77; 95% CI, -1.06 to -0.48). Napping sleep duration did not change in either group. Among the nulliparous women, both first-trimester 24-h sleep duration and its change throughout pregnancy were inversely associated with birth weight (β = -0.44; 95% CI, -0.68 to -0.21; β = -1.75; 95% CI, -3.17 to -0.30, respectively). No associations were detected in multiparous women for nightly and napping sleep duration. CONCLUSIONS Nulliparous women with greater decreases in sleep duration throughout their pregnancy gave birth to newborns with lower birth weight z-scores.

Anemia e níveis de hemoglobina em crianças indígenas Xavante, Brasil Central

RESUMO: Objetivo: Avaliar a prevalencia de anemia, os niveis medios de hemoglobina e os principais fatores nutricionais, demograficos e socioeconomicos associados em criancas Xavante, em Mato Grosso, Brasil. Metodos: Realizou-se inquerito em duas comunidades indigenas Xavante na Terra Indigena Pimentel Barbosa visando avaliar todas as criancas com menos de dez anos. Foram coletados dados de concentracao de hemoglobina, antropometria e aspectos socioeconomicos/demograficos por meio de avaliacao clinica e questionario estruturado. Utilizaram-se os pontos de corte recomendados pela Organizacao Mundial da Saude (OMS) para a classificacao de anemia. Analises de regressao linear com hemoglobina como desfecho e regressao de Poisson com variância robusta com presenca ou nao de anemia como desfechos foram realizadas (intervalo de confianca de 95% -IC95%). Resultados: Os menores valores medios de hemoglobina ocorreram nas criancas com menos de dois anos, sem diferenca significativa entre os sexos. A anemia atingiu 50,8% das criancas, prevalecendo aquelas com menos de dois anos 2 anos (77,8%). A idade associou-se inversamente a ocorrencia de anemia (razao de prevalencia - RP - ajustada = 0,60; IC95% 0,38 - 0,95) e os valores medios de hemoglobina aumentaram significativamente conforme o incremento da idade. Os maiores valores de escores z de estatura-para-idade reduziam em 1,8 vez a chance de ter anemia (RP ajustada = 0,59; IC95% 0,34 - 1,00). A presenca de outra crianca com anemia no domicilio aumentou em 52,9% a probabilidade de ocorrencia de anemia (RP ajustada = 1,89; IC95% 1,16 - 3,09). Conclusao: Elevados niveis de anemia nas criancas Xavante sinalizam a disparidade entre esses indigenas e a populacao brasileira geral. Os resultados sugerem que a anemia e determinada por relacoes complexas e variaveis entre fatores socioeconomicos, sociodemograficos e biologicos.Objective: To evaluate the prevalence of anemia, mean hemoglobin levels, and the main nutritional, demographic, and socioeconomic factors among Xavante children in Mato Grosso State, Brazil. Methods: A survey was conducted with children under 10 years of age in two indigenous Xavante communities within the Pimentel Barbosa Indigenous Reserve. Hemoglobin concentration levels, anthropometric measurements, and socioeconomic/demographic data were collected by means of clinical measurements and structured interviews. The cut-off points recommended by the World Health Organization were used for anemia classification. Linear regression analyses with hemoglobin as the outcome and Poisson regression with robust variance and with the presence or absence of anemia as outcomes were performed (95%CI). Results: Lower mean hemoglobin values were observed in children under 2 years of age, without a significant difference between sexes. Anemia was observed among 50.8% of children overall, with the highest prevalence among children under 2 years of age (77.8%). Age of the child was inversely associated with the occurrence of anemia (adjusted PR = 0.60; 95%CI 0.38-0.95) and mean hemoglobin values increased significantly with age. Greater height-for-age z-score values reduced the probability of having anemia by 1.8 times (adjusted PR = 0.59; 95%CI 0.34-1.00). Presence of another child with anemia within the household increased the probability of the occurrence of anemia by 52.9% (adjusted PR = 1.89; 95%CI 1.16-3.09). Conclusion: Elevated levels of anemia among Xavante children reveal a disparity between this Indigenous population and the national Brazilian population. Results suggest that anemia is determined by complex and variable relationships between socioeconomic, sociodemographic, and biological factors.

Excesso de peso em funcionários de unidades de alimentação e nutrição de uma universidade do Estado de São Paulo

ABSTRACT Objective To describe the prevalence and identify the factors associated with excess weight in restaurant employees at a public university in the city of São Paulo. Methods A socioeconomic and nutritional census was conducted with 174 individuals to obtain data on body mass, height, and socioeconomic status, using a structured questionnaire. The body mass index was determined, and the cut-off points recommended by the World Health Organization were used. Students t test, Fishers exact test, and the χ2 test were used to verify the differences between the means and prevalences. Poisson regression analyses with robust variance were performed, and the outcomes were excess weight or no excess weight. Results Most of the employees (57.5%) were women; 59.8% were non-white, 45.4% lived with a partner, 26.4% were smokers, and 50.6% were sedentary. There was a predominance of individuals with excess weight (60.9%), and most of them (64.0%) were women, non-white (66.3%), lived alone (58.8%), and were non-smokers (63.3%); furthermore, 62.8% of the subjects engaged in physical activities. There was a significant difference (p=0.03) regarding body mass index and gender, demonstrating more excess weight among the women. Excess weight was dependent on the age group and was more likely to occur in individuals over 50 years of age (adjusted prevalence ratio: 1.72; 95% confidence interval: 1.02 - 2.98). Conclusion There was a high prevalence of excess weight in these professionals, indicating the necessity for interventions to control this important risk factor for chronic non-communicable diseases.
