Abstract
- Introduction: Over 50% of US adults older than 75 live free of atherosclerotic cardiovascular disease (ASCVD) and diabetes (DM), yet data on incident statin use among this population are lacking. Our objective was to assess statin initiation by age among the Women’s Health Initiative cohort free of ASCVD and DM at baseline (1993). Hypothesis: Statin initiation is higher at older ages and differs by race/ethnicity. Methods: Exclusions were statin use at baseline, known ASCVD, DM, and no follow-up after baseline. Self-reported medication use was assessed in 1996 and 2008. Specific statin and dose prescribed at the time of initiation were identified using National Drug Codes and determined statin intensity, defined by the ACC/AHA guidelines. We estimated the adjusted association between age group ( Results: Over 12 years of follow-up, 27% of 99,631 women free of ASCVD and DM at baseline initiated a statin; initiation was lower with older age (Table). This association remained after adjustment for ASCVD risk factors and did not differ by race/ethnicity (p for interaction >0.5). Moderate intensity dose was most common at statin initiation overall, and moderate and high intensity dose were both lower with older age. Conclusion: Of women free of ASCVD and DM, women older than 75 were least likely to start a statin and most likely to start low intensity statin therapy at initiation than younger women. We identified a potential clinical gap for investigation: whether lower overall use of statins and lower intensity statin therapy among older women are associated with preventable ASCVD.
