Table 1 BMI, self-evaluation of weight and ratings of the most similar shape, the most desirable shape, most respected shape in the country of origin and most healthy shape: Descriptive statistics (Means ± SD and results from t-tests) and regression coefficients from the multiple regression analysis (MRA) of shape ratings (dependent variables) on ethnic-cultural group (0 = European; 1 = Kiribati), centered BMI and interaction term (predictors)

From: Cultural differences in food and shape related attitudes and eating behavior are associated with differences of Body Mass Index in the same food environment: cross-sectional results from the Seafarer Nutrition Study of Kiribati and European seafarers on merchant ships
