Abstract
OBJECTIVES
To investigate the trajectories of social networks and interactions among older Japanese individuals during the COVID-19 pandemic.
STUDY DESIGN
We used data from a cohort of community-dwelling older individuals from the Otassha study's 2019-2022 survey. Participants comprised 606 older individuals who participated in the 2019 survey and were followed up at least once.
MAIN OUTCOME MEASURES
Social networks were assessed using the Lubben Social Network Scale-6 (LSNS-6), whereas social interactions were assessed by the frequency of face-to-face or non-face-to-face contact with non-resident family members and friends. Trajectories of the LSNS-6 and face-to-face and non-face-to-face interactions were identified using group-based semiparametric mixture modeling. The trajectories of change in the LSNS-6 from 2019 were also identified. The factors associated with the changes in trajectory patterns were examined using logistic regression analysis.
RESULTS
Three LSNS-6 trajectories were identified, with slightly decreasing patterns over time. Specifically, face-to-face interactions tended to decrease over time, whereas non-face-to-face interactions exhibited almost no change. The reduction in LSNS-6 in the decreased pattern failed to recover to its pre-pandemic level. The group of participants with the decreased pattern had a significantly higher proportion of people participating in group activities [odds ratio (95 % confidence interval): 2.27 (1.12-4.59)] and performing calisthenics twice a week than the group with the maintained pattern [2.08 (1.18-3.68)].
CONCLUSIONS
During the three years of the pandemic, no changes were observed in the social networks of community-dwelling older Japanese individuals.
