A multivariate logistic regression analysis was conducted to the effects of health status and health behaviors on depression, shown in Table 4. This analysis focused on those health- status and health-behavior variables that were found statistically significant in the previous analyses of differences in depressed and nondepressed participants. The results showed that country of origin, stillbirth experience, perceived health status, meal skipping, and physical activity were the significant predictors of depression,
explaining 25.5% of the variance (c2 ¼ 57.01, p < .001). Specifically,the country of origin also significantly affected depression: Chinese immigrants had about a 2.5 times greater risk for depression compared to Vietnamese immigrants. With respect to perceived health status, the odds ratio of having depression for immigrant women with a stillbirth experience compared to those with no such experience was 9.73 (95% CI [1.06, 88.95]). Participants who rated their health as poor were approximately 3.2 times more likely to become depressed than their counterparts with good perceived health status (95% CI [1.01, 10.33]). As for health behavior factors, immigrant women who skipped meals two to three times per week had 2.82 times the likelihood of being depressed than those who rarely skipped meals (95% CI [1.24, 6.42]). Participants who did not exercise had 2.76 times increased risk of developing depression than those who did (95% CI [1.57, 4.86]).
