Study Finds Surprising Side Effect of Obesity

The New York Times’ Well blog reports on a new study in the AJM that has found a link between body mass index (BMI) and waistline to the risk of hearing loss. Researchers evaluated BMI, waistline and physical activity of 68,421 women who were part of the Nurses’ Health Study II and asked them to report on hearing loss. After controlling for age, smoking, diabetes, hypertension and other risk factors, researchers showed that the higher the BMI the greater the risk for hearing loss. This relationship was linear and also held true for waistline, where those with a larger waistline had a greater risk. Experts suggest that “obesity might compromise blood flow to the inner ear.”
