Abstract
INTRODUCTION: The associations of physical activity and depressive symptoms with cognitive decline are likely age dependent. Understanding the age differences can be helpful to prevent cognitive decline effectively. The study aimed to investigate the age differences in the associations of leisure-time physical activity (LTPA) and depressive symptoms with cognitive decline in older Taiwanese. METHODS: A total of 3545 participants, aged ?50 years, from 2003 (baseline) and 2007 (end-point) survey datasets were analysed. Cognitive decline was defined as a remarkable decrease on the Short Portable Mental Status Questionnaire. The long-term LTPA and depressive symptoms considered the pattern of change between the two time-points. Logistic regression analysis was conducted to evaluate the associations, stratified by age groups. RESULTS: The association between the long-term LTPA and cognitive decline was significant in the older group (aged ?70), but not in the younger group (aged 50-69). Compared to those with inactive LTPA in both time-points, participants in the older group were less likely to have a cognitive decline if they were active in both time-points (odd ratio, OR: 0.27, 95% confidence interval, 95%CI: 0.14, 0.52), activity increased (OR: 0.32, 95%CI: 0.15, 0.71), and activity decreased (OR: 0.47, 95%CI: 0.23, 0.96). Meanwhile, significant associations were observed between the long-term depressive symptoms with cognitive decline in both the younger and older groups. DISCUSSION: These findings highlight the existence of age differences in the associations of LTPA and cognitive decline. The benefit of LTPA and impact of depressive symptoms should be taken into consideration for different age groups.
