Characteristics of the subcohort by BMI group in women of the InterAct study.

Data are means and SDs for continuous and percentages and frequencies for categorical variables. 152 women in the subcohort were underweight (BMI2) and were excluded from this table; 69 women in the subcohort had missing values for BMI and were excluded from this table.aData on WC and waist-hip ratio were not collected at the centre in Umea, Sweden (excluded from these summaries).bFamily history data were not collected at the centres in Italy, Spain, Oxford, or Heidelberg, so these countries have been excluded when calculating percentages of individuals with/without a family history of diabetes.
