Chen et al. Respond to “Obesity and Asthma”.

The authors respond to a commentary by Stephen C. Redd and Ali H. Mokdad on their paper about the status of overweight and obesity as possible causes of asthma. They commend Redd and Mokdad for their perspective on the relation between obesity and asthma incidence in women in Canada. They recognize the importance of establishing the link between obesity and asthma to the prevention and control of both diseases. In addition, the authors note a higher risk of asthma among women who lost or gained weight.
