This qualitative study was based on individual interviews with 75 Brazilian women in an impoverished peri-urban squatter community (favela) in southeastern Brazil. The purposes of the study were to describe women's role involvement in domestic and employment contexts; identify stresses and satisfactions of maternal, spousal, and employment roles; and assess personal and environmental role constraints and resources from the perspective of women's health. The analytic approach to the interview data was qualitative content analysis, through which thematic categories of maternal, spousal, and employment role satisfactions and stresses were identified by the researchers. Women's unrelenting work in the face of harsh social and economic environments was a broad theme woven throughout the women's descriptions of their lives. The confluence of role constraints affecting the participants' lives included poverty, marginalization, abuse, and lack of support and recognition by partners and society. In order to overcome great adversity and meet heavy role demands, these women relied on self, faith in God, family, and health resources. Implications for women's health promotion are discussed.
