“…The tendency towards overweight observed among the Caboclo adolescents sampled is in accordance with the national and international surveys (WHO, 2005;Popkin, 2007), and in agreement with other studies, which have shown an increase in prevalence of overweight in adolescents from some rural groups in Brazil (Dutra et al, 2006;Leite et al, 2007;Sampei et al, 2007). This should serve as an alert for the possible effects of poor economic and socio-ecologic conditions in the development of overweight/obesity and associated diseases later in life (Ziol-Guest et al, 2009).…”

Anthropometric Measurements of Adolescents From Two Amazonian Ecosystems: Variations According to Seasonality

et al. 2009

This paper aims to describe the nutritional status of Caboclo adolescents living in two areas of the Amazon Basin. Two cross-sectional studies, the first in the dry and the second in the wet season, were carried out in two Amazonian ecosystems: the forest and black water ecosystem, and the floodplain and white water ecosystem. Measurements of weight, stature, arm circumference and triceps, subscapular and suprailiac skinfolds were performed on 247 adolescents (10-19 years of age). Nutritional status was classified using body mass index according to international criteria and the prevalence of underweight and overweight was estimated. Linear mixed effects models were used with the anthropometric measurements as dependent variables and time interval, place of residence, sex, age and stature variation as independent variables. During the wet season, the prevalence of overweight among girls was higher in the forest (42%) than in the floodplain (9%). Longitudinal linear regression models showed that the arm circumference measurement was influenced both by seasonality and location, revealing that the increment between dry and wet seasons was less pronounced in the floodplain. At the time of the study, overweight already constituted a major public health concern among girls living in the forest area. In order to develop adequate public health policies for this important segment of the Amazon population further studies are necessary to investigate the role of environment and seasonality on the growth and nutritional status of adolescents.

“…Studies conducted in the last two decades among different ethnic groups in the Brazilian Amazon and Central Brazil have demonstrated high prevalences of chronic undernutrition in children, often affecting more than a quarter of those below five years of age [4-6]. The results of the First National Survey of Indigenous People's Health and Nutrition, which evaluated the Brazilian indigenous population in 2008-2009, confirmed the scenario previously outlined by local case studies, pointing to height-for-age deficit as a highly prevalent nutritional disorder among indigenous children [7].…”

BackgroundThe aim of this study was to characterize the nutritional status of Xavante Indian children less than 10 years of age in Central Brazil and to evaluate the hypothesis of an association between child nutrition and socioeconomic differentiation in this population.MethodsA cross-sectional study was conducted in July 2006 that included all children under the age of 10 from the Xavante village Pimentel Barbosa in Mato Grosso, Brazil. The data collected included weight, height, and sociodemographic information. Sociodemographic data were used to generate two indices ("income" and "wealth") and to determine the proportion of adults in each household. Descriptive analyses were performed for weight-for-age (W/A), height-for-age (H/A), and weight-for-height (W/H) using the NCHS and the WHO growth references. Univariate and multivariate analyses were conducted using H/A and W/A as a response variables.ResultsOf a total of 246 children under the age of ten residing in the village, 232 (94.3%) were evaluated. Following the NCHS reference, 5.6% of children under the age of ten presented low W/A and 14.7% presented low H/A. Among children under the age of five, deficit percentages for weight and height were 4.5% and 29.9%, respectively, following the WHO curves. Among children < 2 years of age, H/A index variability was found to be directly related to child's age and inversely related to the proportion of adults in the household. Maternal BMI was positively associated with growth for children from 2 to 4 years of age, explaining 11.5% of the z-score variability for the H/A index. For children 5 years of age and older, the wealth index and maternal height were positively associated with H/A. No significant associations were found using W/A as the dependent variable.ConclusionThis study demonstrated that undernutrition, in particular linear growth deficit, is a notable health issue for Xavante children. These findings contrast with the nutritional profile observed among Brazilian children nationally, which is characterized by a sharp decline in child undernutrition in recent decades, even in the poorest regions of the country. This discrepancy calls attention to the persistent health disparities that exist between indigenous and non-indigenous people in Brazil.

“…Recent studies on the nutritional status of Indian children in this age group have showed prevalences ranging from 10% to 60%. 5,6,7,8,9,10 According to estimates, the prevalence of anemia in children under five years old in Latin America is around 40%, thus characterizing anemia as a serious public health problem. Among indigenous children, this value is even higher.…”

Objective: To evaluate the nutritional status of indigenous children of the Aruak and Karibe linguistic families from the Upper Xingu, Central Brazil, and study the relationship between hemoglobin levels and children's gender, age and nutritional status. In total, 470 children under age ten were studied in 2001/2002. Methods: For children under five years old, the diagnosis of undernutrition was based on the heightfor-age and weight-for-age indices, with a cutoff value of two standard deviations below the mean values expected for the age and gender reference - WHO, 2006. A diagnosis of overweight was made when the weight-for-height indice was two standard deviations above the mean expected for the same reference; children between five and ten years old were classified as being underweight, overweight or obese according to their body mass index (BMI) by gender and age, as proposed by Cole et al. The diagnosis of anemia was based on hemoglobin concentrations below 11.0 g/dl for children between 6 and 59 months old or below 11.5 g/dl for children between 60 and 120 months old. Results/conclusion: Growth deficit was highly prevalent among the Indian children. Low weight-for-height was a very rare condition and overweight was significant among the younger and the older children. About 70% of the children were anemic, and age seems to be the main factor associated with low hemoglobin concentrations.
