Cancer caregiving predicts physical impairments: Roles of earlier caregiving stress and being a spousal caregiver
Menée aux Etats-Unis par enquête auprès de 1 517 aidants familiaux d'un conjoint atteint d'un cancer, cette étude évalue l'association entre leur expérience d'aidant, le stress subi et la survenue de problèmes de santé 5 et 8 ans après le diagnostic de cancer
BACKGROUND The objective of this study was to investigate associations between earlier caregiving experience and the development of physical impairments over the subsequent 6 years among family caregivers of patients with cancer. METHODS Family caregivers of cancer survivors participated in a nationwide survey 2 years after their relative's cancer diagnosis (T1) (N=1517) with follow-up at 5 years (T2) and 8 years (T3) postdiagnosis. Caregivers self-reported their demographics and levels of caregiving stress at T1. Caregiving status (“former” for those whose patient was remission, “bereaved” for those whose patient had died, and “current”) and the presence of 3 physical impairments (arthritis, chronic back pain, and heart-related diseases) at the time of assessment were measured at T1 through T3. RESULTS Caregiving stress was significantly related to concurrent presence of the 3 impairment markers at T1. Stressed caregivers also were more likely to develop heart diseases, and spousal caregivers were more likely than other caregivers to develop arthritis and chronic back pain several years after the initial caregiving experience (at T2 and T3). These effects were independent of age, sex, education, and income at T1, and they were also independent of caregiving status at each assessment. CONCLUSIONS The current findings suggest that the adverse long-term health effects of earlier caregiving stress and of being a spousal caregiver should be acknowledged and that caregiving-related stress management programs should be incorporated into routine health care for family caregivers of cancer patients.
