Abstract:

vitamin a (va) is an essential micronutrient for the immune system and several researchs have shown a synergic relationship between vitamin a status and morbidity. the aim was to show the relationship between serum retinol level, conjunctival impression cytology (cic), anthropometric status, and morbidity in low income school children. 445 children (both genders) between 4 and 13 years old were assessed. serum retinol levels (hplc-r), creactive protein (nefelometry) and cic (icepo), anthropometric indicators (weight-height (wh), height-age (ha) according to national references values), morbidity (diarrhea, respiratory tract infections, measles, and parasitosis) two months prior to the evaluation, were determined. the poverty was 92.3%, wasting (wh ≤ p10) 7%, overweight (wh > p90) 10.8%, and stunting (ha = p3) 1.5%. 18% had one or more diarrhea episodes, 39.8% upper respiratory tract infections, 28.1% lower respiratory tract infections, and 32.8% intestinal parasitosis; 10.3% showed a high level of c-reactive protein (crp > 10mg/l). the average retinol level was 35.7 ± 9.2μg/dl, with 0.7% low level (< 20μg/dl), 27.4% of the children at risk of vitamin a deficiency (20-30μg/dl), and 9.5% deficient according cic. there was a significant correlation between serum retinol and cic, and a significant association between serum retinol and upper respiratory tract infections, but not between morbidity and cic. there was not a significant association between anthropometric indicators and vitamin a status and morbidity. in this study it was not possible to demonstrate the relationship between vitamin a status and diarrhea, measles, lower respiratory tract infections and parasitosis but the high prevalence of marginal serum retinol levels and morbidity in this group makes it susceptible to nutritional surveillance. an venez nutr 2008;21 (1): 5-13.
