Group-Based Medical Mistrust in Adolescents With Poorly Controlled Asthma Living in Rural Areas.

Abstract

Black youth and rural adolescents are two groups who experience asthma disparities. Racism and discrimination in health care likely lead to group-based (systems-level) medical mistrust for some adolescents. Group-based medical mistrust, one pathway by which racism drives health inequities, is associated with poorer outcomes for patients with chronic conditions. Despite its potential importance in adolescent asthma, previous research has not considered group-based medical mistrust in this population. To fill this gap, we characterize group-based medical mistrust among rural adolescents with poorly controlled asthma, examining demographic differences. We analyzed baseline data from a school-based clinical trial in which 164 adolescents (mean age = 16.3; 76.2% Black) completed the Group-Based Medical Mistrust Scale (GBMMS). Using linear regression, we tested associations with race, gender, and age, controlling for recent medical visits and insurance status. The total GBMMS mean score was 2.3 (SD = 1.22); subscale scores ranged from 2.3 to 2.4. Black adolescents reported significantly higher total GBMMS scores (β = .45, p = .003) and significantly higher scores on two GBMMS subscales: suspicion of health care providers (β = .56, p = .007) and lack of support from health care providers (β = .36, p = .007). Gender and age were not associated with GBMMS scores. Health care providers need to consider medical mistrust and its role in their clinical care. Together with their institutions, health care providers and researchers should work toward changing systems that perpetuate racism to build trust as a means of reducing asthma disparities among adolescents.
