Re: Effectiveness of home based early intervention on children’s BMI at age 2: randomised controlled trial

Thank you for your work and your article, it proved to raise a lot of debate and discussion within our unit.

As said in your article, obesity is intrinsically an intergenerational process. In clinical practice, we do see significant number of obese or overweight children and they tend to have parents who are obese or overweight. From the data reported in your article, it appears that the intervention group of children had a slightly lower weight and slightly longer length at 2 years of age, with a lower BMI when the 2 sets of parameters were put together. I wonder if you have any data on mother's, or perhaps even biological father's, weight and height, and thus their BMI in the 2 groups? I am curious that these factors could be potential confounders and they were not addressed in your article.
