Financial strain among Mexican American adult child caregivers of the oldest old

BACKGROUND As more adults assume caregiving responsibilities for their aging parents, a key question emerges: Does coresidence increase financial strain for adult child caregivers? OBJECTIVE To examine whether coresiding with an oldest-old parent (aged 80+) is associated with higher financial strain among adult child caregivers. METHODS This study uses data from the Hispanic Established Population for the Epidemiologic Study of the Elderly (2010–2011), a population-based survey of Mexican Americans in five southwestern US states (N = 659). Logistic regression and propensity score–matched logistic models are used to examine the association between coresidence and caregiver financial strain, accounting for selection into coresidence. RESULTS Coresiding caregivers had more than twice the odds of experiencing financial strain compared to non-coresiding caregivers (OR = 2.17 [95% CI: 1.22–3.82], p = 0.007). This relationship remained robust in the matched sample (OR = 2.02 [95% CI: 1.06–4.02], p = 0.038). Poor parental health independently increased the odds of caregiver financial strain in both the full (OR = 3.63 [95% CI: 1.38–12.5], p = 0.019) and the matched sample (OR = 2.20 [95% CI: 1.01–5.36], p = 0.061). CONCLUSIONS These findings suggest that coresidence often functions less as a financial buffer and more as a conduit for high-intensity care, thereby elevating caregiver financial strain. Policies aimed at promoting caregiver financial autonomy – including tax credits, paid family leave, and expanded home- and community-based services – should take into account the distinct vulnerabilities of coresiding caregivers.
