Does Weight have an Impact on Asthma?

There were 3 articles in the June issue of the Journal of Allergy and Clinical Immunology(JACI) that investigated the effect of weight or BMI on asthma. Interesting implications could be garnered from these published articles. Abstracts of these articles can be seen at JACI online

Key implications taken from these articles include.

• Currently being overweight in children is associated with dyspnea and bronchial hyperresponsiveness(BHR) at preschool and school age.
• Being overweight does not have a lasting effect on childhood dyspnea and BHR if the child develops a normal weight. See abstract on Scholtens' article.
  
• There is an association between central obesity and the presence and severity of asthma thus, measuring waist circumference should be considered, in addition to weight and height to better assess obesity and asthma risk. See abstract
  
• There is a modest association between an increased BMI and reduced therapeutic effect of inhaled corticosteroid containing regimens indicating that there might be a reduced response to ICS-containing medications. See abstract.

Thus cut back on those carbs and calories, get your kids active and yank them away from TV and video games.
