Comparison of the mean (95% confidence interval) annual unadjusted percentage rates of change in forearm BMD, grip strength, balance and gait velocity between men and women divided into three different age-change categories. A significant age-by-gender interaction was detected for BMD (p < 0.01). All p-values represent differences after adjusting for covariates: *p < 0.001, 70+ and 60–70 versus 50–60 years, †p < 0.001, 70+ versus 60–70 years, ‡p < 0.05, 70+ versus 50–60 years, **p < 0.05, 60–70 versus 50–60 years.
