Is Obesity Associated with an Increased Risk for Airway Hyperresponsiveness and Development of Asthma?

Table 1 Demographics of Total Evaluated and Included Patients

*Characteristics*	*Number (%)*
Number of subjects evaluated	1,372
Number of subjects included	861 (63%)
Number of subjects excluded	511
Reasons of exclusion
COPD	293
Smoking history (>10 pk-yr)	168
Restrictive lung disease	38
Congestive heart failure	12
Number of subjects with bronchial hyperresponsiveness	401 (47%)
Number with obesity >30 kg/m²	337
Mean FVC (% predicted) in subjects with AHR	89.67 ± 14.88

AHR = airway hyperresponsiveness; COPD = chronic obstructive pulmonary disease; FEV₁ = forced expiratory volume in 1 second; FVC = forced vital capacity.
