Abstract
OBJECTIVE: To examine the sociodemographic factors associated with subclinical vitamin A deficiency in a representative sample of Colombian children. Subjects and methods A cross-sectional, descriptive study was conducted of data from the 2010 National Nutrition Survey of Colombia (ENSIN 2010) on 4,279 children aged 12 to 59 months. Plasma vitamin A levels were measured using high resolution liquid chromatography (HRLC), and sociodemographic factors (sex, age, ethnicity, SISBEN score, and geographic region) were collected using a structured survey. Prevalence rates and associations were established using a multivariate regression model. RESULTS: Vitamin A levels ranged from 7.5-93.7 μg/dL (mean=26.2; 95% CI, 25.9 to 26.5μg/dL). Vitamin A levels less than 20 μg/dL (subclinical deficiency) were found in 24.3% of children. Children belonging to ethnic groups of African ascent, those living in the Orinoquia and Amazonia regions, and those aged 12-23 months had the greatest subclinical vitamin A deficiencies (29.5%, 31.1%, and 27.6% respectively. Regression models showed that age ranging from 12 and 23 months (OR 1.32; 95% CI, 1.01 to 1.73), a SISBEN score 1 (OR 1.66; 95% CI, 1.18 to 2.34), an African ascent (OR 1.35; 95% CI, 1.05 to 1.74), and living in the Orinoquia and Amazonia regions (OR 2.38; 95% CI, 1.62 to 3.51) were factors associated to subclinical vitamin A deficiency. CONCLUSIONS: The study population shows a high prevalence of subclinical vitamin A deficiency, and comprehensive interventions involving nutritional and educational components are therefore recommended.
