Abstract
OBJECTIVE: Minority stress may contribute to poor health by dysregulating stress response systems, including diurnal cortisol rhythms. However, few studies have examined the association between sexual and gender minority stress and diurnal cortisol in lesbian, gay, bisexual, and transgender (LGBT) individuals. The current investigation tested whether the daily experience of minority stressors is uniquely related to diurnal cortisol above and beyond general stressors. METHOD: One hundred and 21 sexual and gender minority young adults (aged 18-35, 54.5% female) completed initial and daily evening questionnaires for 7 consecutive days to document daily general stressors and LGBT stressors. A randomly selected subset (n = 58) also provided salivary cortisol samples at wake, 45-min postwake, 12-hr postwake, and bedtime. RESULTS: Controlling for covariates (sex assigned at birth, wake time, bedtime, and day of the week) and general stressors, individuals who reported more LGBT stressors across the week displayed elevated cortisol levels at wake, t(491) = 9.68, p = .002 and 45-min postwake, t(492) = 6.41, p = .011, relative to individuals who reported fewer LGBT stressors. In contrast, after controlling for covariates, the frequency of general stressors only predicted cortisol 12 hr postwake, t(785) = 2.02, p = .043. Diurnal cortisol was unrelated to within-person fluctuations in LGBT and general stressors. CONCLUSIONS: Results imply that the experience of everyday minority stressors is uniquely related to diurnal cortisol and may have implications for the mental and physical health of LGBT adults.
