To the Editor It was with great interest that we read the article by Peterson et al1 using the triponderal mass index for estimating body fat during adolescence.1 We note that total body fat percentage was considered in this article. We also note that the National Health and Nutrition Examination Survey dual-energy radiography absorptiometry data provide information on visceral fat. There is good evidence for the negative effects of visceral fat in adults2 as well as in children and adolescents.3 Therefore, being able to estimate the percentage of visceral and subcutaneous fat would likely be of clinical significance and potentially allows more accurate risk stratification of adolescents. Hence, comparing the predictive power of body mass index versus the triponderal mass index using visceral adiposity would be of great interest.
