To investigate how socio-economic position, demographic factors, degree of integration and dietary indicators are related to BMI/waist:hip ratio (WHR) and to weight dissatisfaction and slimming among South Asians in Oslo, Norway.

Cross-sectional study consisting of a health check including anthropometric measures and two self-administered questionnaires.

Oslo, Norway.

Pakistanis and Sri Lankans (n 629), aged 30–60 years, residing in Oslo.

BMI was positively associated with female gender (P = 0·004) and Pakistani origin (P < 0·001), and inversely associated with years of education (P = 0·011) and eating more hot meals (P = 0·016). WHR was positively associated with male gender (P < 0·001), age (P < 0·001) and a dietary pattern with high-fat foods (P = 0·005), and inversely associated with degree of integration (measured by a composite index, independent of duration of residence; P = 0·017). One-third of those with normal weight and most of those obese were dissatisfied with their weight. Among these, about 40 % had attempted to slim during the past year. Dissatisfaction with weight was positively associated with education in women (P = 0·006) and with integration in men (P = 0·026), and inversely associated with physical activity (P = 0·044) in men. Women who had made slimming attempts had breakfast and other meals less frequently than others (P < 0·05).

Weight dissatisfaction exists among South Asian immigrants. More research is needed regarding bodily dissatisfaction and the relationship between perception of weight and weight-change attempts among immigrants in Norway, in order to prevent and treat both obesity and eating disorders.
