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

Abstract

Introduction: Growing evidence has documented the adverse impact of the global coronavirus pandemic on sleep quality. Older adults may be especially susceptible to declines in sleep quality for multiple reasons, including their elevated risk of social isolation and loneliness during the pandemic. Given the adverse health consequences of poor sleep, there is a need to identify resilience factors that help protect older adults against decreased sleep quality. Social integration is a plausible resilience factor because involvement in a broad range of social relationships is thought to promote psychological well-being (e.g., meaning, purpose in life), as well as reduce the intensity and duration of negative psychological states. Social integration may also assume increased importance during the coronavirus pandemic because of normative declines in overall social contact. This prospective study assessed the impact of the coronavirus pandemic on older adults' sleep quality and tested whether social integration moderated the impact of the pandemic on sleep quality. Methods: A sample of 115 retired older adults (mean age = 68.6, 58% female, 89% white) completed self-report assessments of their social integration (number of roles on Cohen's Social Network Index) and sleep quality (global score on Pittsburgh Sleep Quality Index) before and after the onset of the coronavirus pandemic (mean duration of follow-up = 2.3 years). Results: Multilevel analyses indicated that social integration moderated the impact of the coronavirus pandemic on sleep quality; there was no main effect of time. Older adults with low social integration had reduced sleep quality from Time 1 to Time 2 (b=.94, p=.02), whereas older adults with high social integration showed no changes in sleep quality over time (b=-.38, p=.37). Conclusion: Broader social networks confer resilience against pandemic-related declines in sleep quality among older adults. The level of social integration should be addressed when studying or treating sleep complaints during the coronavirus pandemic. Additional research is warranted to determine whether psychosocial interventions targeted towards older adults with low social integration can reduce observed differences in sleep quality.
