Goal: The American Heart Association/American Stroke Association has specific recommendations for secondary stroke prevention. The aim of this study was to compare health behaviors engagement between stroke survivors and propensity score-matched controls. Methods: We conducted a retrospective, cross-sectional, matched case-control study using data from the 2015 Behavioral Risk Factor Surveillance System (BRFSS) survey. We included older adults aged 50 or older who participated in the 2015 BRFSS survey and completed the interview. Each case was matched to 3 controls (1:3) based on propensity scores to increase the power of the analyses. Stroke survivors were compared with controls on their physical activity, smoking, alcohol use, body mass index (BMI), last flu immunization, last physical checkup, last blood cholesterol check, heavy drinking, and vegetable and fruit consumption. We used binomial logistic regression to assess health behaviors among stroke survivors compared with controls. Results: The final study sample consisted of 13,249 stroke survivors and 39,747 controls without stroke after propensity score matching. Multivariable analyses revealed that there were significant differences between stroke survivors and matched controls in terms of BMI, physical activity, smoking status, alcohol consumption, and vegetable and fruit consumption. For example, stroke survivors were 51% more likely to be smokers (adjusted odds ratio [AOR] 1.51, 95% confidence interval [CI], 1.32-1.73) and 14% less likely to consume alcohol (AOR.86, 95% CI.78-.95). Conclusion: Findings from our study indicate that compared with propensity score-matched controls, stroke survivors engage in poorer health behaviors with the exception of alcohol consumption.
