[Bone mineral density of the lumbar spine, the femoral neck and femoral diaphysis in a Genevan population sample].
Bone mineral density (BMD) was measured by dual photon absorptiometry in the lumbar spine, femoral neck and midfemoral shaft in 209 women and 165 men aged 20 to 98 years recruited among the Geneva population. The prevalence of various factors (life style, calcium intake, body weight) which may be associated with a higher risk of osteoporosis was evaluated. Between the different skeletal sites, BMD was closely correlated. Nevertheless, BMD at one site failed to accurately predict BMD of another site. In each age class, BMD was dispersed over a wide range. Women and men had similar lumbar spine BMD. In women, BMD decreased after the fifth decade by 1.3, 1.0 and 2.6% year in the lumbar spine and femoral neck and shaft, respectively. Daily calcium intake from dairy products was 430 g and 750 g in women and men, respectively. Femoral shaft BMD was positively correlated with calcium intake. These BMD values obtained in a sample of the normal Geneva population should be of major help for the diagnosis of osteoporosis.
