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

Data are means and SDs for continuous and percentages and frequencies for categorical variables. Twenty men in the subcohort were underweight (BMI2) and were excluded from this table; 41 men 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.
