  1. BMI, waist and hip circumferences shown are those measured at enrollment. For the differences of means between the groups the p-values were assessed using the t test. For the differences in the frequency distribution between the groups the p-values were assessed with the chi-square test.
  2. The superscripts indicate the p-values as follows: ap > 0.05, bp < 0.05, cp < 0.01, dp < 0.001 and ep < 0.0001. *The sum of the percent of None, Father and Mother less the percent of both parents gives 100%.
