Obesity-Related Factors Affect RCC Risk

Restricted access

Obesity and related health risks, including diastolic blood pressure and fasting insulin level, are confirmed as risk factors for renal cell carcinoma (RCC), according to a study in the open-access journal PLoS Medicine.

Using a Mendelian randomization framework, the researchers analyzed gene variants associated with 13 obesity-related factors, identified from large-scale genome-wide association studies. The variants were used as proxies for measures of obesity, blood pressure, lipids, type 2 diabetes, insulin, and glucose. These factors were analyzed for association with the development of RCC in 10,784 cases and 20,406 controls. For each risk factor, odds ratios (ORs) for
