Ethnic Determinants of Health and Medication Use for Depression Among US Latinx Adults

BACKGROUND: Medication use for depression among US Latinx adults is low (34%) and commonly associated with systems-related and individual-related cultural factors. Social determinants of health (SDH) include economic, environmental, educational, community, and healthcare systems factors. Ethnic determinants of health (EDH) are SDH factors specific to an ethnic group and described by an ethnic and disparities framework. OBJECTIVE: To assess relationships between EDH factors and depression medication use among non-Latinx White (NLW) and Latinx adult populations using data from a weighted national sample for hypothesis building. METHODS: Weighted responses to 2015–2018 National Survey on Drug Use and Health surveys from NLW, Latinx, and Latinx adult respondents from Puerto Rico, Mexico, and other Latinx countries were compared. Bivariate analyses were conducted using 2-way cross tabulation and a Wald chi-square test of association. EDH variables were characterized within the construct domains of systems-related geographic location, education, and economic stability, and individual-related cultural factors. RESULTS: Prescription medication use for depressive symptoms is 16.6% (P < 0.05) lower among a national sample of Latinx compared with NLW adults with major depressive episode (MDE). Many differences among systems-level EDH variables between Latinx and NLW populations with MDE were also found between populations with depression medication use. Of note, seeing a primary care provider or psychologist or social worker was significantly different among populations with MDE but not for those with depression medication use. Individual-related cultural EDH variables of overall health and serious psychological distress were significantly worse for Latinx than NLW populations with depression medication use. However, stigma, healing beliefs, and religious beliefs were not different between populations with MDE or depression medication use. Differences between certain Latinx populations with depression medication use were found with limited English proficiency and living in poverty. EDH variables for environment-physical characteristics or community and interpersonal levels of analysis were not represented within the NSDUH survey. CONCLUSION: Seeing a primary care provider or behavioral health specialist, depression severity, and overall health status appear to be important factors related to depression medication use among Latinx adults. Given the limitations of these analyses, multivariate analyses of EDH factors and other Latinx populations are warranted.
