Many studies in the literature have examined older adults' past and current lifestyles in either positive or negative association with their life satisfaction levels. Health capabilities naturally decline with aging and can consequently be related to older adults' life satisfaction levels. Thus, the present study sought to examine the effects of age difference, lifestyles, and health capabilities on older adults' life satisfaction levels. A total of 290 older adults from three clinical research centers in the United States completed a self-administered questionnaire on their lifestyles and life satisfaction levels, and their health capability assessments were evaluated. There was a significant effect of advancing age on life satisfaction levels among older adults. Additionally, engagement in exercise or physical activity significantly influenced life satisfaction levels. However, there were no statistical effects of vital signs and functional assessments of health capabilities on life satisfaction among older adults. The findings suggest that advancing age itself is the strongest factor in older adults' life satisfaction. Additionally, engagement in exercise and physical activity can enhance life satisfaction levels as a supplemental factor among older adults. These findings can be beneficial to optimize life satisfaction levels through appropriate programs to encourage positive lifestyles among older adults.
