Comparison of major depressive disorder onset among foreign-born Asian Americans: Chinese, Filipino, and Vietnamese ethnic groups

Using a nationally representative sample of 1280 Asian Americans, we examined the extent to which major depressive disorder (MDD) onset differs by ethnicity and its associated factors for each of the three ethnic groups: Vietnamese, Filipino, and Chinese. We employed the Kaplan–Meier method to estimate the survival and hazard functions for MDD onset by ethnicity, and cox proportional hazards models to identify socio-demographic and immigration-related factors associated with MDD onset. Approximately 7% of the entire sample had experienced MDD onset in their lifetime. Filipino immigrants showed the highest survival function, followed by Vietnamese immigrants over time. Those who were never-married or divorced were more likely to experience MDD onset when compared to their married or cohabiting counterparts. Those who immigrated at a younger age were more likely to experience MDD onset than were those who immigrated at an older age. However, there were ethnic variations in terms of the risk factors that were associated with MDD onset across these three ethnic groups. Findings from this study signal the importance of understanding the differing experiences of MDD onset by ethnicity.
