Tuesday April 24, 2012 (foodconsumer.org) -- Scientists at Medical Corps, Israeli Defense Force in Israel conducted a study and found overweight in adolescence is associated with increased risk of future urothelial cancer.

The study posted online April 18, 2012 showed that the body mass index at age 17 equal to or greater than 85th standard percentile was associated with 42 percent increased risk of urothelial cancer.

By another overweight, people are overweight if their body mass index is equal to or greater than 25 kg/m2\. Those who were overweight by this definition were 36 percent more likely to develop urothelial cancer.

Obesity has been associated with a variety of malignancies. The current study may be the first, according to the authors, to find the association between being overweight at a young age and future risk of urothelial cancer.

The study led by Adi Leiba and colleagues involved 1,110,835 Israeli adolescents who were examined for fitness for military duty between 1967 and 2005\. The body mass index for the participants were measured at age 17 and during the 18-year follow-up, 661 people developed urothelial cancer of the bladder, ureter, or renal pelvis.

Interestingly, urothelial cancer was less common in the more educated people and among those ho attended religious schools.

Urothelial cancer is a type of bladder cancer.
