Abstract

BACKGROUND: Cancer caregiving has been associated with worsening health among caregivers themselves, yet demographic and psychosocial predictors of their long-term health decline are less known. This study examines changes in caregivers' physical health 2 to 8 years after their family members' cancer diagnosis and prospective predictors of that change. METHODS: Caregivers (n = 664; mean age, 53.2 years) participated in a nationwide study at 2 (T1), 5 (T2), and 8 (T3) years after their family members' cancer diagnosis. Physical health (12-item Medical Outcomes Study Short Form Health Survey Physical Component Scale) was assessed T1 through T3 as outcome. Predictors were self-reported at T1, including caregiver demographics (age, sex, education, income, relationship to patient, and employment status), patient cancer severity (from medical records), and caregiver psychosocial factors (caregiving stress, caregiving esteem, social support, and depressive symptoms). Latent growth modeling tested predictors of caregivers' initial physical health and their physical health change across time. RESULTS: At T1, caregivers reported slightly better physical health than the US population (M = 51.22, P = .002), which declined over the following 6 years (Mslope = -0.27, P < .001). All demographic factors, patient cancer severity, and T1 caregiving stress were related to caregivers' initial physical health (P ≤ .03). Higher depressive symptoms were unrelated to caregivers' initial physical health, but were the only significant predictor of caregivers' more rapid physical health decline (B = -0.02, P = .004). CONCLUSION: Findings highlight the unique contribution of caregivers' depressive symptoms to their physical health decline. Assessing and addressing depressive symptoms among caregivers early in the cancer survivorship trajectory may help to prevent premature health decline among this important yet vulnerable population.
