The last-decade incidence of myocardial infarction (MI) has diminished dramatically in most age groups but not in middle-aged women in Sweden. There has been a large influx of immigrants and it has been shown that immigrant wom en have a higher BMI and are less physically active than Swedish women. Thereby they have a higher risk for heart disease. The aim of the study was to examine post-migration diet ary changes, and knowledge about risks for heart diseases among Somali women. Furthermore, to examine the women’s perceptions of body image, self-esteem, and their knowledge about the positive effect of physical activity. The qualitative research method was used and eight Soma li women aged 40 years or more, who have lived in Sweden longer than ten years, were in terviewed with the help of a semi- structured questionnaire. The study revealed that S omali migrated women in Sweden had changed their diet and experienced weight increase. They reported low self-esteem and little motivation for physical activity. They understood t hat they had a higher risk for heart disease as compared to Swedish women and they had, in gener al, a preference for big body size. The women of this study are, in combination with other risk factors, at a high risk of myocardial infarction. They all revealed a general knowledge a bout the relationship between obesity and inactivity and enhanced risks for heart disease. Th ey had a preference for a larger female body image. They expressed low self-esteem, loneliness, and alienation from society. It is important to address the health issue among migrant Somali wo men in Sweden, but since this study had few informants, larger studies and more science is needed to further investigate the problem.
