Being obese and overweight in adolescence may increase the risk of developing kidney cancer in later life, reports a new study. The findings of the study are published in the International Journal of Cancer.
Being overweight has been linked with a higher risk of developing a form of kidney cancer called renal cell carcinoma (RCC) among adults, but it's unclear if this risk is present during adolescence.
In a study of adolescents who were followed for 37 years, researchers observed a trend for higher RCC risk with increasing body mass index during adolescence, where a one-unit increase in body mass index conferred a six percent increased the risk of RCC.
"This is, to our knowledge, one of the first studies to show that overweight and obesity in adolescence, in a large cohort, is associated with a substantially increased risk of developing renal cancer later in life," said co-author Dr. Pernilla Sundqvist, of University Hospital Örebro, in Sweden.
"New data supporting a link between adolescent overweight/obesity--alone and in combination with low physical working capacity--and renal cancer adds further important evidence supporting the implementation of early interventions within the rapidly growing group of overweight and obese teenagers."
