Sex Specificity of Asthma Associated With Objectively Measured Body Mass Index and Waist Circumference: The Humboldt Study.

The article provides information on a study that investigates the possibility of sex specificity for the association of obesity and asthma using objective measures of body mass index (BMI) and waist circumference. Ever-asthma was defined as lifetime physician-diagnosed asthma, and recent asthma was defined as asthma diagnosed by a physician during the past 12 months. The study demonstrates that the increased risk of asthma associated with obesity was only significant in women but not in men even when BMI was objectively measured, and this association was robust to the anthropometric measures.
