Item The effects of loneliness on depressive symptoms among older adults during COVID-19: longitudinal analyses of the Canadian longitudinal study on aging(2023) Wister, Andrew; Li, Lun; Levasseur, Mélanie; Kadowaki, Laura; Pickering, JohnObjectives: This paper examines the longitudinal effects of changes in the association between loneliness and depressive symptoms during the pandemic among older adults (65+). Methods Baseline (2011–2015) and Follow-up 1 (2015–2018) from the Canadian Longitudinal Study on Aging (CLSA), and the Baseline and Exit waves of the CLSA COVID-19 study (April–December, 2020) (n = 12,469) were used. Loneliness was measured using the 3-item UCLA Loneliness Scale and depression using the CES_D- 9. Results Loneliness is associated with depressive symptoms pre-pandemic; and changes in level of loneliness between FUP1 and the COVID Exit survey, adjusting for covariates. No interaction between loneliness and caregiving, and with multimorbidity, on depressive symptoms were observed, and several covariates exhibited associations with depressive symptoms. Discussion Strong support is found for an association between loneliness on depressive symptoms among older adults during the pandemic. Public health approaches addressing loneliness could reduce the burden of depression on older populations.Item Examination of the healthy caregiver effect among older adults: findings from the Canadian longitudinal study on aging(2023) Li, Lun; Wister, Andrew; Mitchell, BarbaraIntroduction: The Healthy Caregiver Hypothesis (HCH) suggests that caregiving is associated with beneficial health impacts for family caregivers. However, mixed results have been reported, particularly when different levels of caregiving intensity were examined. This study analyzes the relationship between caregiving intensity and three health indicators (functional health, chronic illness, and self-rated general health) among Canadian older adults over 3 years. Methods: We drew upon a subsample of 11,344 participants aged 65 years and older from the Baseline and Follow-up 1 data of the Canadian Longitudinal Study on Aging and used linear mixed models to test the hypothesis based on different levels of caregiving intensity. Results: Older adults who provided low-intensity care recently or continuously reported better functional health and self-rated health than noncaregivers. In contrast, older adults with low-intensity caregiving responsibility reported more chronic conditions over time compared to noncaregivers, but this association was not found for high-intensity caregivers. Discussion/Conclusion: This study elucidates the HCH by incorporating caregiving intensity to understand patterns of better functional health and perceived health but more chronic conditions. The findings yielded from different health indicators suggest the impact of caregiving on health may be domain specific.Item Multimorbidity resilience and health behaviors among older adults: a longitudinal study using the Canadian longitudinal study on aging(2022) Wister, Andrew; Li, Lun; Whitmore, Carly; Ferris, Jennifer; Klasa, Katarzyna; Linkov, IgorThere has been a growing interest in examining why some individuals adapt and bounce back from multimorbidity (resilience) better than others. This paper investigates the positive role of protective health behaviors on multimorbidity resilience (MR) among older adults focusing on older persons with two or more concurrent chronic conditions, and separately for three multimorbidity chronic illness clusters.Item Transition into the caregiver role among older adults: a study of social participation and social support based on the Canadian Longitudinal Study on Ageing(2023) Li, Lun; Wister, Andrew; Lee, Yeonjung; Mitchell, BarbaraObjectives Older adults (65 years and older) are increasingly providing care for their spouses, family members, and nonkin others (e.g., friends and neighbors). However, available knowledge of older caregivers is limited to spousal caregivers and their psychological outcomes. Other caregiver role types or social outcomes among older caregivers are less well studied. Thus, this study examines the social participation and social support among older caregivers by comparing 3 types of older caregivers, including spousal caregivers, nonspouse family caregivers, and nonkin caregivers. Methods Participants for this study were drawn from the Baseline and Follow-up 1 data from the Canadian Longitudinal Study on Aging. A total of 3,789 older adults became caregivers during the 2 data collection time points. Linear mixed models were applied to examine the change of social participation and social support among the three caregiver role types over the course of survey. Results The study finds that after transitioning into the caregiving role, spousal caregivers, and nonkin caregivers experienced a decline in social participation, and spousal caregivers also received less social support over time. When comparing the 3 caregiver role types, spousal caregivers reported the greatest decline in social participation and social support. Discussion This study adds to the relatively limited knowledge of older caregivers by presenting the changes in social participation and social support after transitioning into 3 types of caregiver roles. The results indicate the need to provide support for caregivers, particularly spousal and nonkin caregivers, to help them maintain social relationships and networks for participation and support.
