Physician Trust and Home Remedy Use Among Low-Income Blacks and Whites with Hypertension: Findings from the TRUST Study

Introduction: Home remedies are used for the treatment of hypertension despite unsubstantiated claims of their effectiveness. Home remedy use is often attributed to mistrust towards healthcare providers. Few studies examine the relationship between home remedy use and physician trust. The objective of this study was to examine and compare the association between home remedy use and trust in physicians in a cohort of low-income Blacks and Whites with hypertension living in an inner city in Alabama. Methods: A cross-sectional examination was conducted among 925 Black and White patients receiving care at an urban hospital. Data was collected from in-person surveys. Trust in physicians was self-reported using the Hall General Trust Scale which included questions about honesty, confidentiality, and trust. Home remedy use was self-reported using the Brown and Segal scale which included questions about home remedy use and types of home remedies used. Covariates included demographic factors such as age, race, gender, and health outcomes. Data were analyzed using linear regression. Results: Twenty-eight percent of Black and 15% of White participants reported home remedy use (p = 0.001). Black home remedy users (38.9) and non-users (39.3) had similar trust scores (p = 0.582). Whites home remedy users (32.9) reported lower trust in physicians than White non-users (37.7) (p = 0.026). Conclusions: Black home remedy users, non-users, and White non-users reported similar trust scores; the lowest trust scores were found among White home remedy users. Home remedy use was higher among Black participants. Future studies should examine the context of mistrust and home remedy use among Whites.
