Maceió, AL, Brazil.Federal University of Alagoas. Faculty of Nutrition. Campus A.C. Simões. Maceió, AL, Brazil.Anemia is a major public health problem in preschool children in Alagoas, Brazil, especially in the younger population, because of a positive correlation between hemoglobin level and age. However, due to the lack of studies, it is not known how widespread this condition is among older children or how it is associated with socioeconomic status. The aim of this study was to investigate the prevalence of and factors associated with anemia in school children from the city of Maceió, Alagoas state, Brazil. The analysis was stratified to identify any effect modification according to whether they attend public or private schools

Food intake and nutritional status of preschool from maroon communities of the state Alagoas, Brazil

OBJECTIVE: To assess the dietary intake and the nutritional status of children from Alagoas maroon communities. METHODS: Cross-sectional study involving 724 children (12-60 months) from 39 Alagoas maroon communities. The nutritional status was investigated by anthropometric, biochemical (hemoglobin) and food consumption indicators. RESULTS: The prevalence of anemia, stunting and obesity were, respectively, 48.0, 9.7 and 6.0%. The children had a monotonous eating pattern and a considerable prevalence of inadequate intake of zinc (17.0%), folate (18.1%), iron (20.2%) and vitamins A (29.7%) and C (34.3%). Compared to the other socioeconomic classes, the E class children had lower average consumption (p<0.05) for energy, carbohydrate, vitamins A and C, folate, iron, zinc and phosphorus. CONCLUSIONS: Anemia is a serious Public Health problem. The prevalence of chronic malnutrition and obesity were similar to those observed for the children in the State as a whole, where a nutritional transition process is occuring. There was a high prevalence of inadequate food intake risk for zinc, folate, iron and vitamins A and C, suggesting the need for nutritional education actions

Health promotion initiatives at school related to overweight, insulin resistance, hypertension and dyslipidemia in adolescents: a cross-sectional study in Recife, Brazil

Abstract Background The emergence of diseases such as dyslipidemia, systemic arterial hypertension, insulin resistance and metabolic syndrome in children and adolescents has brought about a change in the epidemiologic profile of the pediatric population. As action to promote health in the school environment is a useful tool for changing the pattern of health/disease in the young population, the present study aimed to identify schools that promote healthy eating and physical activity and to study the relationship between these practices and the prevalence of overweight, hypertension, insulin resistance and hypercholesterolemia in adolescents. Methods A cross-sectional population-based study was conducted with 2400 adolescents aged from 12 to 17 years old and participating in the “Study of Cardiovascular Risk in Adolescents” (ERICA – Estudo de Riscos Cardiovasculares em Adolescente). The association between dependent (overweight, insulin resistance, hypertension and dyslipidemia) and independent variables (implementation of health promoting initiative in schools) was investigated using the chi-square test and prevalence ratio (PR) with a confidence index (CI) of 95%. Results The unsatisfactory implementation of a “health promoting environment” (PR = 1.02; CI 95%: 1.0; 1.04) and “partnerships with the health sector” (PR = 1.03; CI 95%: 1.01; 1.05) were linked to a high prevalence of overweight in adolescents. Hypercholesterolemia was found to be higher in the schools with unsatisfactory implementation of “healthy eating and health on the scholar curriculum” (PR = 1.71; CI 95%: 1.22; 2.44) and those lacking a “healthy-eating promoting environment” (PR = 1.29; CI 95%: 1.10; 1.54). Schools with unsatisfactory implementation of a “health-eating promoting environment” (PR = 1.36; CI 95%: 1.04; 1.79) and those lacking “partnership with the health sector” (PR = 2.12; CI 95%: 1.38; 3.24) had more adolescents with insulin resistance. There was no association between hypertension and any other component studied. Conclusion Schools which have implemented adequate health promotion in their curriculums showed a lower prevalence of overweight, insulin resistance and hypercholesterolemia in adolescents
