Abstract

Part of our original analyses was performed with overweight and obese preschoolers only. This procedure may have created a subgroup of individuals with extreme values at baseline and this may likely be inappropriate.

Part of our original analyses was performed with overweight and obese preschoolers only. This procedure may have created a subgroup of individuals with extreme values at baseline and this may likely be inappropriate. It is conceivable that these subjects were in an extreme state when they were measured at baseline and that over time, one would expect them to regress back to a more normal state, independent of any intervention. We did not take into consideration the phenomenon called regression to the mean [1, 2]. As a result, we cannot make any affirmative statements about the effectiveness of our interventions since a) there were no differences in changes in BMI percentile among the three groups when all preschoolers were analyzed together; and b) in the subgroup of overweight and obese preschoolers, all three groups, including the controls, regressed back towards a more normal state, even though the changes observed in intervention Group A were not statistically significant.
