Social Frailty and Cognitive Impairment in Older Adults

I read the article published in this journal, which was written by Lee et al, with great interest.1 The authors conducted a long-term follow-up study to investigate the association between social frailty and cognitive impairment in older adults. The odds ratios (ORs) [95% confidence intervals (CIs)] of adults with social prefrailty and frailty for cognitive impairment were 1.30 (1.10–1.54) and 1.41 (1.16–1.71), respectively. Regarding the components of social frailty, social inactivity and loneliness were significantly associated with cognitive impairment.
