The associations of social isolation with depression and anxiety among adults aged 65 years and older in Ningbo, China

Abstract

Abstract Social isolation was associated with emotional problems (depression and anxiety) among older adults, however, little is known in China. Thus, we conducted a cross-sectional study including 6,664 ≥ 65 years older adults in Ningbo, China. We collected data on social isolation, depression, and anxiety by specific scales. The relationship between social isolation and emotional problems was estimated by multivariate-adjusted logistic regression models. The population–attributable risk percentage (PAR%) was used to explore the contribution of social isolation to emotional problems. Overall, the percentage of participants who had experienced social isolation, depression, and anxiety was 12.67%, 4.83%, and 2.63%. Compared with the elderly without social isolation, the adjusted odds ratios (95% confidence interval) of depression and anxiety with social isolation were 1.77 (1.25–2.51) and 1.66 (1.05–2.63), respectively. The PAR analysis showed that 10.66% of depression and 9.03% of anxiety could be attributable to social isolation. In the gender subgroup, ORs and PAR% were only significantly observed in female participants. In Chinese older adults, social isolation has been linked to depression and anxiety, suggesting the importance of taking effective and feasible interventions to reduce social isolation and emotional problems, especially among females.
