Higher FSH Level Is Associated With Increased Risk of Incident Hip Fracture in Older Adults, Independent of Sex Hormones

J Clin Endocrinol MetabPublished Case-cohort study

Authors' conclusion

Higher FSH is associated with an increased risk of subsequent hip fracture. Our findings support a growing body of evidence for the direct pleiotropic effects of FSH on bone and for a role for FSH in aging and disability independent of sex hormone levels.

Main finding

As reported in the abstract

Incident hip fracture per sex-specific SD increase in FSH

HR, adjusted for age and sex

1.24

95% CI 1.04–1.48P = .02

HR, further adjusted for estradiol, testosterone and SHBG

1.20

95% CI 1.01–1.44P = .04

Observational data: associations, not effects.
