BackgroundPrevious research has shown two-way associations between rental tenure, poorer housing quality, and health outcomes, but little research has looked at relative housing contributions to health outcomes.AimsWe investigated whether tenure and/or dwelling condition were associated with housing-sensitive hospitalizations and whether any association differed by income.MethodUsing a data set of housing characteristics matched to hospitalization records, rental tenure data, and income quintiles, we modeled differences in housing-sensitive hospitalization rates by ecological-level tenure and housing condition, controlling for age-group and mean temperatures.ResultsThere were clear associations between income, tenure, and house condition, and winter-associated hospitalization risk. In the adjusted model, the largest risk differences were associated with neighborhoods with low income (risk ratio [ RR] = 1.48) and high rental tenure ( RR = 1.41). There was a nonsignificant difference for housing condition ( RR = 1.04).DiscussionRental tenure and poor housing condition were risks for housing-sensitive hospitalization, but the association with income was stronger. Higher income households may be better able to offset quality and tenure-related health risks. This research illustrates the inverse housing law: Those most vulnerable, with most need for good-quality housing, are least likely to have it. Income inequity is inbuilt in tenure, quality, and health burden relationships.ConclusionThese findings suggest that measures to address health inequities should include improvements to both tenure security and housing quality, particularly in low-income areas. However, policymakers aiming to reduce overall hospitalization rates should focus their efforts on reducing fuel poverty and improving the affordability of quality housing.
