Description/Overview: The Asian Women’s Health Research Network (ASIA-WH) was initiated in 2007 by women’s health researchers in three countries including the U.S., South Korea, and Taiwan. Then, researchers from Japan joined the ASIA-WH later in 2013. The ASIA-WH aims at promotion of collaborative research among researchers who are working on Asian women’s health across the countries. The network has provided a channel for global communication and collaboration, and the researchers have collaborated in publications, grant writing and submission, cross-cultural pilot studies, and research conference presentations. This symposium presents three different studies on Asian women’s physical activity that have been conducted by current members of the ASIA-WH during the past several years. The first study explored the factors influencing physical activity of older women with Type 2 diabetes in South Korea. A drastically increasing number of South Korean older women (aged 65 years and older) and their high prevalence rate of Type 2 diabetes necessitate this study. The second study explored the relationships between Asian American midlife women’s physical activity and their sleep-related symptoms while considering other covariates. Physical activity has been suggested as a good strategy to reduce midlife women’s sleep-related symptoms. Thus, this study aimed to examine the association in Asian American midlife women to provide directions for development of future interventions to reduce the women’s sleep-related symptoms. The third study targeted to preliminarily evaluate a culturally tailored Web-based physical activity promotion program for Korean American midlife women. Despite an increasing number of Web-based programs to promote physical activity, very few programs have been tailored to a specific cultural group. Thus, this study showcases the development and preliminary evaluation process of a culturally tailored Web-based physical activity promotion program and to provide directions for future development of culturally tailored Web-based programs to promote physical activity among Asian American women.
