Vitamin D Status of Hong Kong Chinese Infants

Abstract

Vitamin D deficiency is a common nutritional problem of weaning infants in many parts of the world. Hong Kong infants, who are fed with traditional rice-based weaning foods and live in crowded high rise flats, might be expected to suffer from this nutritional problem. Yet a study of 150 bottle fed infants revealed that the vitamin D intake from fortified milk and cereals was more than half of the recommended amount throughout the first 18 months and that the serum 25-OH vitamin D concentration of the infants at 18 months was normal. The effect of sunlight was also evident.
