Association of wider neck circumference and asthma in obese children.
Obesity is a well-established risk factor for asthma. Previous studies have reported that central obesity is associated with asthma.



To investigate the association between fat distribution, which is determined by anthropometric measures, including neck circumference (NC), and asthma in school-aged children.



Children diagnosed as having asthma were enrolled along with controls who were admitted to our outpatient department with allergic symptoms, such as rhinitis, urticaria and atopic dermatitis. Anthropometric measures, including height, weight, NC, waist circumference, and hip circumference, were obtained. Skin prick tests, blood eosinophil counts, and serum total IgE level measurements were performed.



A total of 196 children (92 male [46.9%]) were included. Asthma was present in 102 patients (52.1%). Ninety-one of the patients (46.4%) were overweight, and 45 patients (22.9%) were obese. The NC of children with asthma was significantly higher than that of children in the control group. Grades defined according to NC percentiles were also significantly different between groups. In children with asthma, the prevalence of children with an NC higher than the 90th percentile (grade 6) was more frequent when compared with controls. The median NC of obese-overweight children with asthma was significantly higher compared with obese-overweight controls without asthma. Results of multivariable logistic regression analysis revealed that the presence of an NC in the greater than 90th percentile was associated with asthma in obese-overweight children.



This study found that NC, which is a simple anthropometric measure, is associated with asthma in obese children.
