Childhood Obesity Linked To Asthma

A Kansas State University graduate student has found a correlation between childhood obesity and asthma.

Sara Rosenkranz, doctoral student in human nutrition, Manhattan, conducted research that found that healthy children with higher levels of body fat and lower levels of physical activity had greater amounts of airway narrowing after exercise.

“Kids who are overweight and inactive are having — even at the age of 8 to 10 years old — a negative response to exercise challenge tests, which might be contributing to the increase that we’ve been seeing over the past several decades in asthma prevalence as well as obesity prevalence,” Rosenkranz said.

Rosenkranz worked with other K-State faculty and students to recruit 40 children in the 8- to 10-year-old age range to participate in exercise studies.

All of the children were healthy, meaning none of took medication or had a diagnoses or history of acute or chronic disease, including asthma.

For Rosenkranz’s project, the children completed pulmonary function tests, an exercise test that doctors often conduct to determine if children have asthma, and body composition tests.

The children also took questionnaires to determine if they were active or inactive compared to the standards of their age, gender and ethnicity.
