OBJECTIVE: This study examined differences in psychologic and physiological responses to caregiving stress in Hispanic and non-Hispanic white women dementia caregivers and noncaregivers. Dependent variables were perceived stress, depression, and salivary cortisol.
METHOD: Eighty-three women caregivers (20 Hispanic and 24 non-Hispanic white) and noncaregivers (19 Hispanic and 20 non-Hispanic white) completed the Perceived Stress Scale (PSS), Center for Epidemiological Studies-Depression Scale (CES-D), and collected three saliva samples daily for 3 consecutive days. A subsample of 17 Hispanic and 28 non-Hispanic white participants matched on age and education was used for the main analyses.
RESULTS: Caregivers had higher levels of 8 am, 5 pm, and 9 pm log cortisol as well as higher perceived stress than noncaregivers. Non-Hispanic whites had higher depression scores than noncaregivers, but there was no significant difference for Hispanics. Hispanics, regardless of caregiving status had flatter daytime cortisol slopes than the non-Hispanic whites. Multivariate regression analyses showed that both ethnicity and depressive symptoms independently predicted daytime cortisol slope.
CONCLUSIONS: Results support the relationship between chronic stress and hypothalamic-pituitary-adrenal axis dysregulation among women dementia caregivers and highlight the need to examine further the role of ethnicity and depressive symptoms in their physiological responses.
