BACKGROUND: The evidence examining the joint effect of leisure-time physical activity (LTPA) participation and cognitive function status on all-cause mortality risk in stroke survivors is limited. This study examines the joint effect of LTPA participation and cognitive function status on all-cause mortality risk in a nationally representative sample of U.S. adult stroke survivors. METHODS: Study sample (N = 139) included older adult (≥ 60 years of age) participants in the 1999-2002 National Health and Nutrition Examination Survey. Cognitive function status was assessed using Digit Symbol Substitution Test scores (high > 36 correct and low ≤ 36 correct). Participation in any volume of moderate-to-vigorous LTPA during the previous month (yes/ no or unable) was assessed via questionnaire. RESULTS: Analysis of stroke survivors with high cognitive function reporting monthly participation in moderate-to-vigorous LTPA revealed a statistically significant decrease in risk of all-cause mortality when compared to a referent group of stroke survivors with low cognitive function reporting no LTPA (Hazards Ratio [HR] 0.39; 95% Confidence Interval [CI] 0.16-0.92; P = 0.0337). A similar statistically significant beneficial relationship was not revealed in those reporting LTPA participation with low cognitive function or in those reporting no LTPA with high cognitive function. CONCLUSIONS: In a nationally representative sample of U.S. older adult stroke survivors, the joint effect of high cognitive function and participation in LTPA was associated with a statistically significant protective effect against all-cause mortality risk.
