Social Integration and Sleep Quality during the COVID-19 Pandemic: Prospective Evidence from a Study of Retired Older Adults.

BACKGROUND: Growing evidence has documented the adverse impact of the global COVID-19 pandemic on sleep quality among older adults. Given the negative consequences of poor sleep, it is critical to identify factors that provide older adults with resilience against worsening sleep quality. Social integration may represent one such resilience factor. PURPOSE: This study evaluated the association of social integration and sleep quality during the COVID-19 pandemic. METHODS: 113 retired older adults completed assessments of their social integration after the onset of the COVID-19 pandemic, and of their sleep quality before and after the onset of the COVID-19 pandemic. RESULTS: Higher levels of social integration were associated with better sleep quality during the COVID-19 pandemic, even when statistically controlling for pre-pandemic sleep quality. Sex-stratified analyses showed that this association was driven by women in our sample. CONCLUSIONS: Social integration may confer resilience against poor sleep quality, especially in older adult women. Additional research is warranted to assess candidate mechanisms and moderators of the link between social integration and sleep quality.

Coping strategies moderate the effect of perceived stress on sleep and health in older adults during the COVID-19 pandemic.

Stress in the context of the COVID-19 pandemic may have a significant impact on health, including sleep health. Older adults may be particularly vulnerable. This study examined associations between perceived stress and sleep health, mental health, physical health, and overall perceived health outcomes among older adults. We also examined whether specific coping strategies moderate these associations. Older adults (n = 115; Mage  = 68.62) reported perceived stress, coping strategies, global sleep quality, depressive symptoms, and perceived mental, physical, and overall health before and during the COVID-19 pandemic. Stress-health relationships were modelled with hierarchical linear regression. Higher perceived stress was associated with greater depressive symptoms and poorer mental health concurrently and longitudinally. Coping strategies moderated the association of perceived stress with physical health and overall perceived health. For example, higher perceived stress was associated with poorer overall perceived health among those with lower problem-focussed coping, but not among those with higher problem-focussed coping. Older adults may benefit from prevention and intervention strategies targeting stress management. Furthermore, identifying people with low problem-focussed coping might be a useful strategy to prevent worsening health in future public health crises.
