Abstract

OBJECTIVE: This survey investigated the relationship between social isolation, depression, nutritional status and quality of life among community-dwelling older adults during COVID-19.
DESIGN: This was a cross-sectional survey study.
SETTING: Communities in Pudong New Area, Shanghai, China that have contracted with Renji Hospital, affiliated with Shanghai Jiao Tong University School of Medicine.
PARTICIPANTS: From May to July 2022, 406 community-dwelling older adults were selected by convenience sampling in Shanghai, China.
PRIMARY AND SECONDARY OUTCOME MEASURES: The Lubben Social Network Scale, Geriatric Depression Scale, 36-item Short Form Health Survey Scale and risk assessment of malnutrition were used in older adults. Mediation models were constructed to determine the mediating role of depression and nutritional status on social isolation and quality of life among older adults.
RESULTS: The prevalence of social isolation among older adults in the community was 44.3%. The total social isolation score in community-dwelling older adults was positively associated with the total malnutrition risk and quality of life scores, and negatively associated with depression (p<0.01). Logistic regression demonstrated that living alone, loss of families or friends during COVID-19 and depression were risk factors for social isolation among community-dwelling older adults (p<0.05). Social isolation could directly affect the quality of life (β=0.306). In addition, depression (β=0.334) and nutritional status (β=0.058) had a significant mediating effect on the relationship between social isolation and quality of life.
CONCLUSIONS: Our findings showed that the prevalence of social isolation among older adults increased during COVID-19. Depression and nutritional status played parallel mediating roles on the effect of social isolation on quality of life. Community workers and healthcare providers should develop intervention plans to improve the status of social isolation in older adults, eliminating existing and ongoing adverse effects.
