Longitudinal Cohort Study of Depression and Anxiety Among Older Informal Caregivers Following the Initial COVID-19 Pandemic Response in Aotearoa New Zealand

Abstract

Objectives To assess the impact of providing care and conditions of care on psychological wellbeing among older informal caregivers following the initial period of COVID-19 pandemic restrictions in Aotearoa New Zealand. Methods Data were from population-based cohorts of older adults participating in the 2020 Health, Work and Retirement longitudinal survey ( n = 3839, 17.4% informal caregivers). Changes in symptoms of depression and anxiety over 2018–2020 surveys associated with sociodemographic factors, caregiving, cohabitation with the care recipient, assistance provided with activities of daily living, support in providing care, and opportunity cost of care were assessed. Results Increased depression, but not anxiety, was associated with providing informal care. Among caregivers, lower living standards and cohabitation were associated with increased depression. Lower living standards, unemployment, and lower help from friend/family networks were associated with increased anxiety. Discussion Economic hardship and social capital provide targets for supporting psychological wellbeing of older caregivers during periods of pandemic restrictions.
