Abstract
This study investigated the association of race/ethnicity, dietary intake, and physical activity with depression and potential other barriers associated with the use of mental health services among depressed people. We used the nationally representative data, 2011-2016 National Health and Nutrition Examination Survey. Depression status was defined using a Patient Health Questionnaire. Multivariable logistic regressions were conducted on depression status and the use of mental health specialists among depressed adults, accounting for the complex sampling design. The prevalence of depression was 8.3% with substantial racial/ethnic differences (8.0% for white, 3.1% for Asian, 9.2% for black, 7.6% for Mexican Hispanics, 13.0% for other Hispanics). Good/acceptable diet and a high level of physical activity were negatively associated with depression. Among depressed people, no significant racial/ethnic differences were observed in using mental health specialists. Prevalence for depression was lower among people who have good or acceptable diet and moderate physical activity. These modifiable factors as well as race/ethnicity should be incorporated into psychotherapeutic interventions to improve depression.
