Feasibility of a mHealth intervention to increase physical activity and health literacy among Chinese new retirees

Released from the hectic work environment, many new retirees now have time to attend to their own health. This study tested an exploratory mHealth intervention with a design based on Social Cognitive Theory to promote active aging among the newly retired. A convenience sample of 14 community living healthy elderly aged 50 to 62 that retired from full-time jobs in the previous three years was recruited. Participants were given a Mi Smart Band 4 (similar to a Fitbit band) for self-monitoring of physical activities. They attended five health workshops delivered face to face by professionals in health technology, sport, and Chinese medicine. Data on physical activity was gathered from the smartphones that synchronized with Mi Smart Band 4. Focus group interviews were administered before and after the intervention. Results indicated that all participants achieved their steps goal during the program period. The sample on the whole overachieved their steps goal by 22 percent. Participants reported a significant increase in knowledge, skill, and behaviors related to physical exercise as well as Chinese medicine acupuncture points. Participants gained confidence in doing exercise. The health intervention was found feasible and effective in promoting physical exercise and enhancing self-efficacy among newly retired participants. Health organizations should grasp this time window to promote physical activity with the “young-old” cohort.
