This cross-sectional survey of 406 older adults in Shanghai found that social isolation was common (44.3%) during COVID-19 and was directly linked to lower quality of life, with depression and nutritional status acting as significant mediating factors.
This cross-sectional study surveyed 406 community-dwelling older adults in Shanghai, China, between May and July 2022 to examine associations between social isolation, depression, nutritional status, and quality of life during the COVID-19 pandemic. The researchers found a 44.3% prevalence of social isolation. Regression and mediation analyses indicated that social isolation was directly associated with a lower quality of life (β=0.306). Depression (β=0.334) and nutritional status (β=0.058) were significant parallel mediators in this relationship. Risk factors for social isolation included living alone, loss of family or friends, and depression. The study is limited by its cross-sectional design, which prevents causal inference, potential bias from online administration, and a convenience sample not representative of all older adults.
