Brief Summary

This study aims to examine within-person variations of different contexts (time, physical, psychosocial and affective) of active life engagement, and how these variations predict a set of physiological indicators and health-related outcomes among community-dwelling older people. Specifically, this study has the following objectives. Objective 1: To investigate within-person variations in different contexts (i.e., time, physical, psychosocial, and affective) of active life engagement and interactions of these contexts. Objective 2: To examine how within-person variations in different contexts (i.e., time, physical, psychosocial, and affective) of active life engagement and interactions of these contexts may associate with a set of cardiovascular indicators measured on daily basis. Objective 3: To examine how within-person variations in different contexts (i.e., time, physical, psychosocial, and affective) of active life engagement and interactions of these contexts may associate with a set of health-related outcomes (e.g., physical functioning, depression, health-related quality of life).
