| Summary: | In northern countries, endogenous synthesis of vitaminD is thought to be limited to the months of Aprilthrough September.1 During the winter months, di-etary or supplemental vitamin D intake at values similar to the recommended intake of 200 IU/day (5 µg/day) is not enough to prevent vitamin D deficiency in young women.2 Vitamin D deficiency is well documented among Canadian women3–7 and young children4,8–11 and has been reported at levels as high as 76 % of women and 43 % of children (3–24 months) in northern Manitoba4 and 48.4%–88.6 % of Aboriginal women and 15.1%–63.5 % of non-Aboriginal women in the Inuvik zone of the former Northwest Terri-tories.3 Vitamin D dependent rickets in children and osteo-malacia in adults are the most commonly reported features of deficiency.12 We sought to determine whether maternal or infant vitamin D deficiency at birth is associated with BMC of Canadian infants. |
