Weight, fat percentage and maternal bone mineral density are determinants of bone mineral density in adolescent and young adult females. Bol. Med. Hosp. Infant. Mex.

Introduction. Osteoporosis is a public health problem. It is important to characterize the factors which predispose to a low bone mineral density (BMD) since adolescence. Material and methods. Twenty eight mother-daughter pairs were studied. BMD was measured by dual X-ray absorptiometry in several anatomic sites, anthropometric measures were obtained. Pearson's córrelations and multiple linear regression models were fitted. Results. Weight was the factor most correlated with BMD in all anatomic sites. In multiple analysis, maternal BMD was the most determinant factor of spinal BMD (β =0.363, P =0.01); weight (β =0.018, P < 0.01) and fat percentage (β =-0.013, P =0.02) were in the hip. Conclusions. Heredity is the most determinant factor of spinal BMD; body size and composition are in the hip. Controlling for weight and height, a greater body fat percentage is associated with a lower BMD in young women.
