Protective and high-risk social activities associated with homebound status among older adults in rural Japan

Becoming homebound can be devastating for older adults in rural communities. This study aimed to identify protective or high-risk social activities associated with homebound status among the rural young old (ages 65-74) and the oldest old (ages ≥ 75). We used data from a survey of older adults in a rural community of Japan in 2014. Questions covered sociodemographic characteristics, homebound status (i.e., going out less than once a week), physical and psychological status, and social activities. Using survey data, we conducted logistic regression analysis to identify protective and high-risk social activities associated with homebound status. Of the 1,564 participants, 51.0 % were the oldest old, and the mean age was 75.2 (±7.0) years. The prevalence of homebound status was 10.5 % total: 5.2 % among the young old and 15.7 % among the oldest old and highest among the female oldest old (19.4 %). The main protective social activity for the young and the oldest old was visiting friends' houses (adjusted odds ratio [AOR] 5.38, 95 % confidence interval [CI] 1.64-17.64 and AOR 3.49, 95 % CI 1.07-11.42, respectively). For the young old, specific high-risk social activities were advising family and friends (AOR 0.07, 95 % CI 0.01-0.62) and activities to support older adults (AOR 0.17, 95 % CI 0.03-0.84). For the oldest old, a protective social activity was participating in long-term care prevention programs (AOR 28.94, 95 % CI 1.90-441.63). To prevent rural older adults from becoming homebound, support should be provided according to protective and high-risk social activities for age groups, with particular attention to safe socialization amid the threat of COVID-19.
