Determinants of trust in health care in an older population.

OBJECTIVES

To explore differences in sociodemographic and psychological correlates of institutional trust in health care in an aging population of African Americans and non-Hispanic whites.

DESIGN

Cross-sectional survey data from the longitudinal Chicago Health and Aging Project.

SETTING

Population-based study of three communities in the Chicago area.

PARTICIPANTS

African Americans (n=2,284) and non-Hispanic whites (1,354) with a mean age of 79.3.

MEASUREMENTS

Demographic factors, socioeconomic status (SES), healthcare access, cynical hostility, perceived discrimination, depression, and institutional trust in health care.

RESULTS

African Americans reported substantially lower healthcare trust than non-Hispanic whites (P<.001). After adjustment for demographic variables and SES, only race (P<.001) and age (P=.008) were significantly associated with healthcare trust scores. The association between race and healthcare trust was slightly attenuated after adjusting for cynical hostility, depressive symptoms, and perceived discrimination (P<.001). Each of these variables was negatively associated with healthcare trust, and together these accounted for approximately 15% of racial differences in healthcare trust.

CONCLUSION

Psychological factors, not demographic characteristics, SES, or healthcare factors, appear to contribute the most to disparities in healthcare trust between older African Americans and non-Hispanic whites.
