Long-Term Oral Bisphosphonate Therapy and Fractures in Older Women: The Women's Health Initiative.

ABSTRACT:

Objectives

To examine the association between long-term bisphosphonate use and fracture in older women at high risk of fracture.

Design

Retrospective cohort.

Setting

Women's Health Initiative.

Participants

Older women who reported at least 2 years of bisphosphonate use in 2008-09 (N = 5,120).

Measurements

Exposure data were from a current medications inventory. Outcomes (hip, clinical vertebral, wrist or forearm, any clinical fracture) were ascertained annually. Using multivariate Cox proportional hazards models, the association between duration of bisphosphonate use (3-5, 6-9, 10-13 years) and fracture was estimated, using 2 years as the referent group.

Results

On average participants were 80 years old and were followed for 3.7 ± 1.2 years. There
