Factors Associated With Poor Health Outcomes Among Vietnamese Americans After Hurricane Harvey, Houston, Texas,...

Immigrants typically experience poor health outcomes after disasters but are often excluded in disaster studies. We assessed physical and mental health outcomes among Houston-area Vietnamese American residents after Hurricane Harvey and hurricane-related characteristics associated with poor health outcomes.

We conducted in-person structured surveys among 120 Vietnamese Americans from November 2018 through February 2019. We used the physical and mental component scores of the 12-Item Short-Form Health Survey to assess health outcomes. We used descriptive statistics for health outcomes and hurricane-related effects and examined the associations between hurricane-related characteristics and health outcomes.

Overall mean (95% CI) physical and mental component scores were 39.8 (29.7-49.9) and 32.6 (27.6-37.6), respectively. The odds of poor physical health poststorm were significantly higher among participants reporting ≥5 versus <5 depressive symptoms (odds ratio [OR] = 3.04; 95% CI, 1.11-8.29; P = .03) and significantly lower among participants with versus without health insurance (OR = 0.25; 95% CI, 0.09-0.71; P = .01). The odds of experiencing poor mental health more than a year after the hurricane were significantly higher among those sustaining versus not sustaining a serious injury/illness because of the hurricane (OR = 3.34; 95% CI, 1.12-9.94; P = .03) and among those who were married/partnered versus not married/partnered (OR = 4.16; 95% CI, 1.32-13.07; P = .02). Receiving versus not receiving free health care services after the hurricane and having high versus low levels of acculturation protected against poor mental health (P < .05 for both).

Our findings highlight the inequalities of postdisaster health outcomes in this immigrant population and emphasize the need for improved disaster recovery programs that account for these factors.
