Celind J, et al. - To quantify the independent relationships between childhood body mass index (BMI) and pubertal BMI change, and the risk of colorectal cancer in males, authors delineated 37,663 males born between 1946 and 1961. They observed the relation of childhood BMI at 8 years of age with increased risk of colon cancer only if it was followed by a pubertal BMI increase above the median (but not with pubertal BMI change). They reported no association between childhood BMI and pubertal BMI change, and rectal cancer.
