New Data Analysis Shows Possible Link between Childhood Obesity and Allergies – 2
Narrator: This is NIH Health Matters. A new study shows that obese children and adolescents are at increased risk of having some kind of allergy, especially to a food. Dr. Darryl Zeldin at the National Institute of Environmental Health Sciences explains that data from a cross sectional study showed risk, not causes.
Zeldin: And what that means is that we take a snapshot of the U.S. population at a single point of time. So because we don’t know whether the timing of the exposure is before or after the health outcome, in this case allergy, we can’t really determine causality.
Narrator: For details on this, and more about medical research, visit www.nih.gov. Health Matters is produced by the National Institutes of Health, part of the US Department of Health and Human Services.
