Positive effects of numerous cardiac rehabilitation programs have been largely documented. However, very few studies have addressed the low participation rates of underprivileged populations. Using Pierre Bourdieu’s sociocultural approach, this qualitative research helps to expand the knowledge base with regard to cardiac rehabilitation practices of men from socio-economically disadvantaged environments. Semi-structured interviews were conducted with 22 French-speaking males (average age : 51.7 years) in the urban Outaouais region, and having suffered a cardiovascular event. Results suggest that social and material deprivation shapes their relation to their bodies that is inconsistent with public health standards. Two main themes are expanded on: a) low disposition towards prevention practices and b) low disposition to participate in a cardiac rehabilitation program.
