Child, Vitamin E Deficiency, Risk FactorsAbstract
Objective: Brazilian national data show a significant deficiency in pediatric vitamin E consumption, but there are very few studies evaluating laboratory-proven nutritional deficiency. The present study aimed to settle the prevalence of vitamin E deficiency (VED) and factors associated among school-aged children attended at a primary health unit in Ribeirão Preto (SP).
Methods: A cross-sectional study that included 94 children between 6 and 11 years old. All subjects were submitted to vitamin E status analysis. To investigate the presence of factors associated with VED, socioeconomic and anthropometric evaluation, determination of serum hemoglobin and zinc levels, and parasitological stool exam were performed. The associations were performed using Fisher's exact test.
Results: VED (α-tocopherol concentrations <7 μmol/L) was observed in seven subjects (7.4%). None of them had zinc deficiency. Of the total of children, three (3.2%) were malnourished, 12 (12.7%) were anemic, and 11 (13.5%) presented some pathogenic intestinal parasite. These possible risk factors, in addition to maternal-work, maternal educational level, and monthly income, were not associated with VED.
Conclusions: The prevalence of VED among school-aged children attended at a primary health unit was low. Zinc deficiency, malnutrition, anemia, pathogenic intestinal parasite, maternal-work, maternal educational level, and monthly income were not a risk factor for VED.
