Does Childhood Obesity Increase the Risk of Adult Cancer?

Friday, August 3rd, 2012

New research published in the journal of Cancer Epidemiology. Biomarkers and Prevention and Obesity concluded that obesity in adolescents has a direct link to the incidence of urothelial (bladder and urinary tract) and colorectal cancers in adulthood when obesity is defined as a Body Mass Index (BMI) in the 85th percentile and above. This group of adolescent has a 1.42% greater chance (50% higher risk) of developing urothelial or colorectal cancer in adulthood than those beneath it.

Researchers conducted a longitudinal study of 1.1 million males in the Israel Defense Force using health information collected by the army for a follow-up period of 18 years. When controlled for factors such as year of birth and education, the researchers discovered a clear link between childhood BMI and those diagnosed with urothelial or colorectal cancer later in life. Although at this time the researchers have only found a link between childhood  BMI and these types of cancer later in life they believe further research may find a wider range of cancers including pancreatic cancer which they are currently researching. Further research will evaluate whether or not obesity is a direct risk factor for cancer or a confounding factor for a genetic variation and whether or not a successful weight loss program can reduce a child’s risk of developing urothelial and colorectal cancer in adulthood.
