Thiazide use is associated with reduced risk for incident lower extremity fractures in men with spinal cord injury

摘要

Objective To determine the association between thiazide use and lower extremity fractures in patients who are men with a spinal cord injury (SCI). Design Cohort study from fiscal years 2002 to 2007. Setting Medical centers. Participants Men (N=6969) with an SCI from the Veterans Affairs (VA) Spinal Cord Dysfunction (SCD) Registry, including 1433 users of thiazides and 5536 nonusers of thiazides. Intervention Thiazide use versus nonuse. Main Outcome Measure Incident lower extremity fractures. Results Among the men, 21% in the VA SCD Registry (fiscal years 2002-2007) included in these analyses used thiazide diuretics. There were 832 incident lower extremity fractures over the time period of this study: 110 fractures (7.7%) in 1433 thiazide users and 722 fractures (13%) in 5536 nonusers of thiazides. In unadjusted and adjusted models alike, thiazide use was associated with at least a one-quarter risk reduction in lower extremity fracture at any given point in time (unadjusted: hazard ratio (HR)=.75; 95% confidence interval (CI),.59-.94; adjusted: HR=.74; 95% CI,.58-.95). Conclusions Thiazide use is common in men with SCI and is associated with a decreased likelihood for lower extremity fractures.
