Abstract
Although some studies have suggested a link between polypharmacy and poor mental health, less is known about the association between polypharmacy and depressive symptomology among U.S.-born older Mexican Americans. This study aimed to test the association between polypharmacy and depressive symptoms in U.S.-born older Latino Americans. Data came from the Sacramento Area Latino Study on Aging (SALSA 2008). A total of 691 U.S.-born older (age >= 65) Mexican Americans entered this analysis. Polypharmacy was the independent variable. Level of depressive symptoms was the outcome. Age, gender, socioeconomic status (education, income, and employment), retirement status, health (chronic medical conditions, self-rated health, and activities of daily living), language, acculturation, and smoking were the covariates. A linear regression model was used to analyze the data. We found a positive association between polypharmacy and depressive symptoms, which was above and beyond demographic factors, socioeconomic status, physical health, health behaviors, language, acculturation, and health insurance. Polypharmacy is linked to depressive symptoms in U.S.-born older Mexican Americans. More research is needed to test the effects of reducing inappropriate polypharmacy on mental well-being of first and second generation older Mexican Americans. There is also a need to study the role of drug-drug interaction in explaining the observed link between polypharmacy and depressive symptoms.
Highlights
Polypharmacy is associated with undesired physical health outcomes such as death [1]
Using data from the Sacramento Area Latino Study on Aging (SALSA)-2008 study, the current study showed that polypharmacy is associated with depressive symptoms in U.S.-born older Mexican Americans
Inappropriate polypharmacy should be prevented in Latino older Americans, and this may contribute to mental health promotion in this population
Summary
Polypharmacy is associated with undesired physical health outcomes such as death [1]. Given the serious consequences and the social and health care costs involved, epidemiologists have shown an increasing interest in understanding mental health correlates of polypharmacy across diverse populations [2]. This is important because polypharmacy has unequal correlates across ethnic groups [3]. Some studies have suggested a link between polypharmacy and poor mental health, less is known about the association between polypharmacy and depressive symptomology among U.S.-born older Mexican Americans. Aim: This study aimed to test the association between polypharmacy and depressive symptoms in U.S.-born older. Conclusion: Polypharmacy is linked to depressive symptoms in U.S.-born older Mexican Americans. There is a need to study the role of drug-drug interaction in explaining the observed link between polypharmacy and depressive symptoms
