Weight Likely Cause for One-Fourth of Asthma Cases in Kids With Obesity (image) Duke University Medical Center Share Print E-Mail Caption A study including health data for more than 500,000 children in the US suggests obesity might be to blame for about a quarter (23 to 27 percent) of asthma in children who are obese. This could mean about 10 percent of all kids ages 2 to 17 with asthma -- almost 1 million children in the US -- might have avoided the illness by maintaining a healthy weight, according to researchers at Duke University and collaborators with the National Pediatric Learning Health System (PEDSnet).
