Abstract: Disability is understood to arise from person-environment interactions. Hence, heterogeneity in local-area characteristics should be associated with local-area variation in disability prevalence. This study evaluated the associations of disability prevalence with local-area socioeconomic status and contextual features. Disability prevalence was obtained from the Canada census of 2001 for the entire province of Québec at the level of dissemination areas (617 in iduals on average) based on responses from 20% of the population. Data on local-area characteristics were urban-rural denomination, social and material deprivation, active and collective commuting, residential stability, and housing quality. Associations between local-area characteristics and disability prevalence were assessed using multilevel logistic regressions. Disability was associated with local-area socioeconomic status and contextual characteristics, and heterogeneity in these factors accounted for urban-rural differences in disability prevalence. Associations between contextual features and disability prevalence were confounded by local-area socioeconomic status. Some associations between local-area socioeconomic status and disability prevalence were moderated by contextual characteristics. The importance of this effect modification is greater when expressed in terms of the absolute magnitude of disability than in the relative likelihood of disability. Explanation of rural-urban differences by the contribution of other local-area characteristics is consistent with the conceptualization of urban-rural categories as the reflection of spatially varying ensembles of compositional and contextual factors. Although local-area socioeconomic status explains most variability in disability prevalence, this study shows that contextual characteristics are relevant to analyses of the spatial patterning of disability as they predict spatial variations of disability, sometimes in interaction with socioeconomic status. This study demonstrates that absolute and relative perspectives on effect modification may lead to differing conclusions.

Abstract: Disability is conceived as a person-context interaction. Neighborhoods are among the contexts potentially influencing disability. It is thus expected that neighborhood characteristics will be associated with disability prevalence and that such associations will be moderated by in idual-level functional status. Empirical research targeting the influences of features of urban environments is relatively rare. To evaluate the presence of contextual differences in disability prevalence and to assess the moderating role of in idual functional status on the association between neighborhood characteristics and disability prevalence. Multi-level analyses of in idual-level data obtained from the Canadian Community Health Survey and neighborhood-level data derived from the Canada census. A contextual component was observed in the variability of disability prevalence. Significant neighborhood-level differences in disability were found across levels of social deprivation. Evidence of person-place interaction was equivocal. The contextual component of the variability in disability prevalence offers potential for targeting interventions to neighborhoods. The pathway by which social structure is associated with disability prevalence requires further research. Analyses of particular functional limitations may enhance our understanding of the mechanisms by which socioenvironmental factors affect disability. Publicly available survey data on disability in the general Canadian population, while useful, has limitations with respect to estimating socioenvironmental correlates of disability and potential person-place interactions.
