E-health Interventions on Promoting Multiple Health Behaviors in Diverse Populations



Evidence has indicated a high prevalence of physical inactivity and unhealthy diet among diverse populations, especially young adults and older adults.  Such unhealthy lifestyles can result in numerous negative consequences for both individuals and societies.  Interventions focused on multiple health behavior changes (MHBC) e.g. physical activity (PA) plus fruit-vegetable consumption (FVC), have been shown to have advantages over those targeting only a single health behavior (PA or FVC), and have therefore gained popularity over the last decade.  Despite the increasing use of Internet technology and the apparent promise of e-health MHBC interventions, there are several remaining questions, e.g. when is the best timing for MHBC intervention delivery?  What are the underlying mechanisms behind a successful MHBC?


As a Post-doctoral Research Fellow in the Department of Sport, Physical Education and Health, I have joined a research team to address these research questions.  Our research team has developed and evaluated several web-based/ smartphone-based MHBC interventions using psychological theories (e.g., Health Action Process Approach, HAPA) and behavioral change techniques (BCTs) to promote PA and FVC among diverse Chinese populations, including college students, discharged patients with cardiac diseases, and Hong Kong Chinese community-dwelling older adults.  We have also primarily investigated the psychological mechanisms of a successful MHBC (e.g., medication and moderation analysis).  Our research may bear considerable theoretical and practical implications for future MHBC interventions and health promotion programmes.  Relevant findings have been published in a series of high-impact peer-reviewed journals and international conferences.


Currently, we are conducting a project to examine the effects of a blended online and offline MHBC intervention on Hong Kong older adults and we intend to investigate more mediators in the MHBC process.
