BMI may underestimate the socioeconomic gradient in true obesity
Van den Berg G, van Eijsden M, Vrijkotte GM, Gemke RJBJ
Body mass index (BMI) does not make a distinction between fat mass and lean mass. In children, high fat mass appears to be associated with low maternal education, as well as low lean mass because maternal education is associated with physical activity. Therefore, BMI might underestimate true obesity in children of low-educated mothers.
