The Association Between Community Dialogue and Loneliness in Rural Japanese Communities: A Cross-Sectional Study

Introduction This investigation explores the influence of community dialogue on loneliness within rural Japanese communities amidst the backdrop of globalization, urbanization, and technological shifts. Highlighting the significance of both informal and formal community dialogues, the study aims to bridge the gap in empirical evidence regarding the role of these interactions in enhancing social cohesion and mitigating loneliness, particularly in rural areas facing demographic changes and privacy concerns. Method A cross-sectional study was performed in Unnan City, Japan, targeting individuals over 40 who regularly visited a local rural hospital. The study employed the Japanese version of the University of California, Los Angeles (UCLA) Loneliness Scale and questionnaires regarding the frequency of community dialogue, alongside examining participants' health and demographic details from hospital records. Analysis methods included t-tests, Mann-Whitney U tests, and multivariate logistic regression to examine the association between community dialogue frequency and loneliness. Results Among the 647 respondents, the participants' mean age was 71.26 years, with a male rate of 46.3%. The multivariate logistic regression analysis revealed that higher frequencies of community dialogue significantly reduce the odds of experiencing loneliness. Specifically, compared to individuals with the least frequency of community dialogue, those with more frequent and most frequent dialogues were significantly more likely to report higher loneliness levels, with odds ratios of 2.62 (95% CI: 1.60-4.29, p<0.01) and 4.11 (95% CI: 2.47-6.85, p<0.01), respectively. Additionally, an increase in BMI was inversely related to loneliness (OR: 0.95, 95% CI: 0.91-0.99, p=0.023), and individuals with a higher comorbidity index (CCI≥5) showed a decreased likelihood of reporting higher loneliness (OR: 0.64, 95% CI: 0.43-0.96, p=0.031). Conclusion This study shows compelling evidence that more frequent community interactions are inversely associated with feelings of loneliness. These findings suggest that initiatives to increase community dialogue need a nuanced approach to mental health and social cohesion in rural settings. The research further reveals an intriguing relationship between body mass index, the severity of comorbidities, and loneliness, offering insights into the complex interplay between physical health and social well-being. The importance of this study lies in its potential to inform policies and programs designed to foster social connections respecting rural contexts, thereby addressing the challenge of loneliness in rural communities.
