Bone density estimates and risk factors for osteoporosis in young women

The bone mineral density [BMD] of the calcaneus was estimated in 185 young women from the United Arab Emirates, using SAHARA ultrasound. All participants completed a questionnaire on factors potentially associated with osteoporosis. In all, 29 [15.7%] of the women were classified as having osteopenia and none as having osteoporosis. Participants with osteopenia were more likely to have had a later onset of menarche, irregular periods, lower body mass index, and a positive family history of osteoporosis. Only late menarche and low body mass index, however, were independent predictors of osteopenia
