Obesity and Physical Education.

D Peter Birkett   (6 December 2004)

Obesity and Physical Education. 6 December 2004
D Peter Birkett, physician private practice Send letter to journal: Re: Obesity and Physical Education. dpb1{at}columbia.edu D Peter Birkett	The paper by Datar and Strurm appears to contain a fallacy of over specific conclusions. They compared the effect on obesity of time in physical education to the effect of time sitting in a classroom. This cannot prove that physical education produces an effect on obesity. Not sitting in in a classroom might be producing the effect. D Peter Birkett MD
