Background: Musculoskeletal symptoms are common adverse effects of statins, yet little is known about the prevalence of musculoskeletal pain and statin use in the general population.
Methods: We conducted a cross-sectional study of the National Health and Nutrition Examination Survey 1999-2004. We estimated the prevalence of self-reported musculoskeletal pain according to statin use and calculated prevalence ratio estimates of musculoskeletal pain obtained from adjusted multiple logistic regression modeling.
Results: Among 5170 participants without arthritis, the unadjusted prevalence of musculoskeletal pain was significantly higher for statin users reporting pain in any region (23% among statin users, 95% confidence interval [CI], 19-27, compared with 18% among those not using statins, 95% CI, 17-20; P=.02) and in the lower extremities (12% among statin users, 95% CI, 8-16, compared with 8% among those not using statins, 95% CI, 7-9; P=.02). Conversely, among 3058 participants with arthritis, statin use was not associated with higher musculoskeletal pain in any region. After controlling for confounders, among those without arthritis, statin use was associated with a significantly higher prevalence of musculoskeletal pain in any region, the lower back, and the lower extremities (adjusted prevalence ratios: 1.33 [CI, 1.06-1.67]; 1.47 [CI, 1.02-2.13]; 1.59 [CI, 1.12-2.22], respectively). Among participants with arthritis, no association was observed between musculoskeletal pain and statin use on adjusted analyses.
Conclusion: In this population-based study, statin use was associated with a higher prevalence of musculoskeletal pain, particularly in the lower extremities, among individuals without arthritis. Evidence that statin use was associated with musculoskeletal pain among those with arthritis was lacking.
