The cultural construction of social support in Brazil: associations with health outcomes.

The association of social support and health outcomes has received considerable attention in recent years, but the cultural dimension of social support has not been extensively investigated. In this paper, using data collected in a Brazilian city, we present results indicating that those individuals whose reported access to social support more closely approximates an ideal cultural model of access to social support have lower blood pressure and report fewer depressive symptoms and lower levels of perceived stress. The cultural model of social support is derived using a combination of participant observation, semi-structured interviews, and the systematic ethnographic technique of cultural consensus modelling. These results are then used to develop a measure of an individual's approximation to that model of social support in a survey of four diverse neighborhoods in the city (n = 250). We call this approximation to the ideal cultural model of social support "cultural consonance" in social support. The association of health outcomes with cultural consonance in social support is independent of individual differences in the reporting of social support, and of standard covariates. In the case of blood pressure and perceived stress, it is independent of diet, and other socioeconomic and psychosocial variables. The association with depressive symptoms is not independent of other psychosocial variables. The implications of these results are discussed with respect to research on cultural dimensions of the distribution of disease.
