“…Iron deficiency during pregnancy is generally associated with low birth weight and preterm birth. 23,28 In the case of the Xavante, the absence of a significant relation may be due to the fact that children tend to be born with adequate weight and only suffer growth deceleration in the third or fourth month of life 30 . However, mean hemoglobin levels in children showed a direct relationship with the mother's age, consistent with findings from other studies of non-Indigenous and Indigenous children 6,29 .…”

“…The recent history of the Xavante people is marked by rapid and profound changes in ecology, subsistence and dietary patterns, and physical activity 7,36 . These changes strongly affect children, especially those under 5 years of age, among whom almost 30% have linear growth deficits 21,30 . Diarrhea accounts for approximately 75% of hospitalizations caused by infections and parasitic diseases, which are responsible for 20% of all hospitalizations 19 .…”

ABSTRACT: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.

Anthropometric and hematological tests to diagnose nutritional deficiencies in schoolchildren of indigenous communities living in the Andean region of Ecuador

et al. 2017

A B S T R A C T ObjectiveTo carry out the anthropometric and biometric-hematological assessments in schoolchildren of the Andean region of Ecuador, in order to improve the diagnosis of nutritional deficiencies. MethodsThe study has been carried out in the San Juan School (Chimborazo, Ecuador), located at 3,240m of altitude, to 36 children of 5 and 6 years old. Anthropometric analyses (weight, height and body mass index), and hematocrit and hemoglobin concentrations were measured. The hemoglobin measurement was evaluated considering the normal value and the one adapted to the altitude of the area. Revista de NutriçãoRev. Nutri., Campinas, 30 (6) ResultsThe schoolchildren showed high prevalence of stunting (44%). The values of hematocrit (p=0.001) and hemoglobin (p=0.003) were higher in girls. It should be highlighted that using the normal value of hemoglobin, anemia was not detected. However almost a fifth of the schoolchildren studied were diagnosed with anemia when we applied the correction factors adapted to the altitude. ConclusionThe use of correction factors adapted to the altitude is considered essential to do the hematology test in populations that live in high altitude in order to avoid a false diagnosis. Moreover, it is necessary to establish the environmental factors related to the stunted growth of this population of the Andean region.Keywords: Anemia. Anthropometry. Biometry. Child development.

R E S U M O Objetivo Realizar avaliações antropométricas e biométrico-hematológicas em escolares da cordilheira dos Andes no Equador, a fim de melhorar o diagnóstico de deficiências nutricionais. Métodos O estudo foi realizado na escola San Juan (Chimborazo, Equador), localizada a 3240 metros acima do nível do mar, a 36 crianças de 5 e 6 anos de idade. Foram analisadas as medidas antropométricas (peso, altura e índice de massa corporal) e as concentrações de hemoglobina e hematócrito. A medida da hemoglobina foi avaliada considerando os valores absolutos e os corrigidos pela altura geográfica. Resultados A população escolar apresentou alta prevalência de altura baixa (44% I N T R O D U C T I O NCurrently, nutritional changes are a Public Health problem in Ecuador, affecting the schoolage population in particular. Undernutrition is one of the major causes of death in children [1]. Infant mortality, difficulty to access resources and education are important problems for the populations living in the Andean region [2][3][4][5]. In Ecuador, there are numerous indigenous communities living under these unfavorable conditions.Investigations on the nutritional status of the Ecuadorian population are scarce. The ELAN Ecuadorian Hospital Malnutrition study reported an undernutrition rate of 37.1% in 2012 [6]. The nutritional status of hospitalized patients was shown as not included within the therapeutic objectives [7]. When analyzing the diets of 110 Ecuadorian adults, it was noted that their daily needs of carbohydrates, vitamins D, E, and minerals, such as iron and calcium were not met [8]. H...

“…They are grouped by general subject such as growth and diet, health and disease and climate change. Some are review papers (Brond ızio et al, 2016;Dorea & Marques, 2016;Dufour et al, 2016) while others are research articles Ferreira et al, 2016;Marques et al, 2016;Silva et al, 2016;Urlacher et al, 2016;Vallinoto et al, 2016;Zhang et al, 2016). The papers present perspectives about ecology, public policy and traditional populations and also discuss theoretical issues such as adaptation, impacts of modernisation/westernisation on vulnerable populations and aspects of life history and health of different groups.…”

“…The papers present perspectives about ecology, public policy and traditional populations and also discuss theoretical issues such as adaptation, impacts of modernisation/westernisation on vulnerable populations and aspects of life history and health of different groups. Ferreira et al (2016) present an analysis of growth curves of Xavante children <10 yrs of age living in central Brazil. They noted that Xavante are one of the larger indigenous groups in Brazil; they have experienced rapid economic and environmental change in recent decades and are now dependent on market resources for dietary and other needs.…”
