The relationship reached a plateau around a BMI of 30 kg\/m2, with little additional increment with further increases in BMI (all P for interaction &amp;lt; .0001, obese vs nonobese). Increasing BMI was linearly associated with decreases in strength index in both women and men. MOFs were ascertained in 3721 women and 276 men (1027 female and 75 male hip fractures). Higher BMI was associated with a lower risk of MOF in women in multivariable models, but this association was largely explained by their higher BMD. Protective association of higher BMI with hip fracture were stronger and only partially explained by BMD (hazard ratio [95% confidence interval] 0.79 [0.73\u20130.99] for obese I and 0.67 [0.46\u20130.98] for obese II).
