Adolescent girls in Maine are at risk for vitamin D insufficiency

, : Adolescent girls in Maine are at risk for vitamin D insufficiency. Journal of the American Dietetic Association 105(6): 971-974

The objective was to determine the seasonal fluctuations in serum 25-hydroxyvitamin D (25-OHD) in a group of healthy adolescents living in a northern climate. Twenty-three 9- to 11-year-old girls participated in the study from September 2000 to March 2003. Serum 25-OHD and parathyroid hormone levels were measured each September and March. Dietary intake of vitamin D was assessed each summer and winter. Summer-sun exposure was evaluated using reports of time spent outdoors.
