Improving nutritional status in obese children with asthma may improve clinical outcomes, according to a cross-sectional, observational study published in Clinical & Experimental Allergy.

Researchers found that mean total carotenoids were lowest in obese children with asthma, lower than both healthy weight patients with asthma and obese control patients. In addition, total carotenoids positively correlated, and the n-6/n-3 polyunsaturated fatty acid ratio inversely correlated, with the forced expiratory volume in 1 second, only in obese patients with asthma.

This was the first study to evaluate the associations among serum carotenoid and fatty acid concentrations, metabolic markers, and pulmonary function in obese-related asthma in children.
