VITAMIN-D DEFICIENCY IN A MANITOBA COMMUNITY

Objective: Using a cross-sectional survey, to investigate the vitamin D status of a random sample of 80 mother-child pairs (child age 3-24 m onths) in a Manitoba community with a high incidence of rickets. Metho d: A questionnaire on feeding habits, gestational history, maternal di et and vitamin supplements was administered to mothers in their homes with the assistance of a local interpreter. Venous blood was collected from both mother and child for serum 25-hydroxyvitamin D levels. Resu lts: Of 91% babies initially breastfed, 36% received no formula or mil k after weaning and 40% received no vitamin supplements. 24% of mother s took no vitamin supplements during pregnancy and lactation. Knowledg e about rickets was poor. In 43% of children and 76% of mothers, serum 25-hydroxyvitamin D levels were below normal range. Conclusions: Vita min D levels are low in this population due to lack of fortified dairy products and vitamin D supplements. A public health program should in clude counselling on rickets and vitamin D supplementation for all inf ants and pregnant or lactating women.
