Associations between smoking and drinking and low forearm bone mineral density in late adolescence.

<p>Odds ratios and 95% confidence intervals for low bone density (z-score below −1 at 17 years of age) are presented adjusted for menarche age and regular sports practice at 17 years of age (squares), and with additional adjustment for body mass index at 17 (diamonds) or for bone mineral density at 13 years of age (triangles).
