Abstract
The purpose of this study was to investigate the relationship between different levels of physical activity (light, moderate, and vigorous), physical health, happiness, and depression among older adults with diabetes. Using data from the National Social Life, Health and Aging Project (NSHAP) Wave 3, the results indicate that moderate and/or vigorous physical activity is more effective than light physical activity for promoting physical health and happiness and lowering depression of older adults with diabetes. This study suggests that activity professionals and therapists working with older adults with diabetes need to encourage their participation in physical activity as well as adjust a level of physical activity intensity that is tailored to participants' needs and expectations.
