Influence of Anthropometric Measurements in Lung Function in Patients With Asthma

BACKGROUND: Obesity is commonly regarded as a risk factor for asthma development, poor asthma control, and poor response to asthma therapy. METHODS: In a cross-sectional study, 85 asthmatics (37 male and 48 female) participated. Pulmonary function tests (PFTs) and anthropometric parameters were measured for each patient. RESULTS: Mean age and median duration were 43.9 ± 10.61 and 6 (3–14) years, respectively. Among anthropometric parameters, only waist-to-hip ratio (WHR) indicated significant correlation with PFTs in both sex (P < 0.05). There were negative associations between waist circumference, hip circumference and WHR with PFTs only in overweight and obese women (P < 0.05). CONCLUSIONS: Some anthropometric parameters affected lung function, and it seems that gender differentially contributes to this effect.
