Vitamin A status and nutritional intake of carotenoids of preschool children in Ijaye Orile community in Nigeria.

This study was carried out to determine the vitamin A status and nutritional intake of carotenoids of 213 children between the ages of 6 months and 6 years in a rural community in Nigeria. There were 109 males and 104 females. A total of 57 (26.8 per cent) children were deficient in serum retinol levels (< 10 microg/dl) while 102 (47.9 per cent) had low levels (10-19 microg/dl). The highest prevalence of serum retinol deficiency was in the 6-12 months age group, most of whom were breastfeeding and there was poor correlation between duration of breastfeeding and serum retinol levels. The prevalence of night-blindness was 1.5 per cent; however, none of the children had xerophthalmia. Chronically malnourished children had lower mean serum retinol levels than well nourished children. There was a high consumption of carotenoid-containing food, but despite this there was a high prevalence of vitamin A deficiency. We therefore suggest that measures to combat vitamin A deficiency should include vitamin A supplementation on a short-term basis. On a long-term basis parents should be educated on the importance of the consumption of locally available sources of provitamin A and pre-formed vitamin A rich foods, and the avoidance of overcooking. Parents should also be encouraged to grow more beta-carotene containing foods.
