Sense of belonging to community and avoidable hospitalization: a population-based cohort study of 456,415 Canadians

A sense of belonging to a community is a dimension of subjective well-being that is of growing population health interest. We evaluated sex-stratified associations between community belonging and risk of avoidable hospitalization. Adult men and women from the Canadian Community Health Survey (2000-2014) were asked to rate their sense of community belonging (N = 456,415) and were also linked to acute inpatient hospitalizations to 31 March 2018. We used Cox proportional hazards models to assess the association between community belonging and time to hospitalization related to ambulatory care sensitive conditions (ACSCs) and adjusted for a range of sociodemographic, health, and behavioural confounders. Compared to those who reported intermediate levels of belonging, both very weak and very strong sense of belonging were associated with greater risk of avoidable hospitalization for women (HR 1.29, 95% CI 1.12, 1.47, very weak; HR 1.15, 95% CI 1.03, 1.27, very strong), but not for men (HR 1.12, 95% CI 0.97, 1.29, very weak; HR 1.08, 95% CI 0.98, 1.19, very strong). This study suggests that community belonging is associated with risk of ACSC hospitalization for women and provides a foundation for further research on community belonging and population health.
