Abstract Objective To explore the relationship between online social network use and social isolation and mild cognitive impairment (MCI) among older adults in the community. Methods From June 2019 to January 2020, 758 middle-aged and elderly people in Fuzhou community were selected as the research subjects. According to the diagnostic criteria of MCI, they were divided into MCI group (179 cases) and cognitive normal group (579 cases). According to the Lubben scale score, a total score of <12 score was divided into the social isolation group (125 cases), ≥12 score was divided into the non-social isolation group (633 cases). The montreal cognitive assessment scale, the instrumental daily living competence scale, the simplified geriatric depression scale (GDS-15), the social network scale, and the online social network use questionnaire were used to evaluate the participants. Results Compared with the cognitively normal group, the MCI group had lower educational level (P ＜ 0.01); GDS-15 score was higher (P ＜ 0.01). There were no significant differences in age, gender, marriage, living status, life style and disease history between the two groups (P ＞ 0.05). The use of online social network in the cognitive normal group was longer than that in the MCI group (P ＜ 0.01). The daily duration of the cognitive normal group was longer than that of the MCI group, but the difference was not statistically significant (P ＞ 0.05). The social isolation group was lower than the non-social isolation group in terms of the number of years of online social network use and the daily length, with highly statistical significance (all P ＜ 0.01). Logistic regression analysis showed that the service life of online social network was related to MCI (OR = 0.181, 95%CI: 0.086, 0.384). Online social network use over 10 years significantly reduced the risk of MCI (OR = 0.263, 95%CI: 0.117, 0.591). There was no connection between the daily time of online social network and MCI (P ＞ 0.05). Conclusion The use of online social networks can reduce the occurrence of social isolation in middle-aged and elderly people and have a protective effect on cognitive function. The longer the use of online social networks, the lower the risk of MCI.
