Underweight men had significantly increased odds of fragility fractures (OR, 3.44; 95%\u2009CI, 1.03 to 11.47; p=0.044) and vertebral fractures (OR, 4.30; 95%\u2009CI, 1.36 to 13.58; p=0.013), compared with men of normal BMI. In contrast, overweight men had lower odds of overall fractures (OR, 0.50; 95%\u2009CI, 0.31 to 0.80; p=0.004) and vertebral fractures (OR, 0.48; 95%\u2009CI, 0.27 to 0.84; p=0.010).
