Factors that influence self-reported general health status among different Asian ethnic groups: evidence from the Roadmap to the New Horizon: Linking Asians to Improved Health and Wellness study.

Little is known about the determinants of self-reported general health status among different Asian ethnic subgroups. Using a community-based participatory research approach, we designed, administered, and analyzed a cross-sectional survey of 705 Asians (292 Chinese, 226 Korean, 187 Vietnamese) in the Portland, Oregon region to describe associations between general health status and several sociodemographic and health-related factors in pooled and ethnic-group-stratified samples. Ethnic variation existed in all covariate distributions, except employment, public-service use, language use, health status, visiting healthcare providers, sleep habits, and use of prayer, meditation, yoga or acupuncture. Acculturation measures were strong predictors of poor/fair health in logistic regression models regardless of ethnicity. Ethnic variation in outcome status existed for all remaining covariates. Most health-related research overlooks the heterogeneity within the Asian population. These findings highlight substantial variability in the associations between self-reported general health status and sociodemographic and health-related measures between Asian ethnic groups.
