OA osteoarthritis, OP osteoporosis, BMI body mass index
*The multivariable-adjusted model was adjusted for sex, age, BMI, smoking status, alcohol drinking status, activity level, mean total energy intake, mean Ca intake, as well as Ca supplementation. The prevalence of osteopenia and OP in overweight (BMI ≥ 25 kg/m2) population was 25.6 % and 6.9 %, respectively
