Obesity is associated with a higher risk of osteoporosis.

Is it true that obesity is associated with a higher risk of osteoporosis?

No. Two large studies (a UK Biobank cohort and a Chinese cross-sectional study) report that osteoporosis prevalence and incidence fall as BMI rises, with obesity associated with lower risk, and a case-control study likewise found no osteoporosis association with obesity. A narrative review notes the relationship is complex and site-dependent, while one cohort's data suggest obesity is associated with osteoporosis and osteoporotic fractures.
