BACKGROUND: Obesity has proven to be associated with respiratory symptoms and @entity73 , which could increase the incidence of @entity260 after bariatric surgery. However, the component of @entity28 that has the most influence on pulmonary function has not been identified, especially in Asian-Pacific populations. METHODS: This cross-sectional study enrolled @entity28 Chinese @entity1 >or=18 years of age with a body mass index (BMI) >32 kg/m(2), who were being evaluated for bariatric surgery. All @entity1 performed pulmonary function test, and the results were analyzed according to various anthropometric measurements. Multiple-regression analyses were also conducted and adjusted for age, sex, and smoking history to determine the factors that impaired the pulmonary function of the @entity28 @entity1 . RESULTS: A total of 150 consecutive @entity1 were enrolled from July 2007 to August 2008. We found that body weight, BMI, waist circumference (WC), hip circumference, and waist-to-height ratio but not waist-to-hip ratio had a significant correlation with decreased forced vital capacity (FVC), forced expiratory volume in the first second (FEV1), @entity358 ( @entity358 ), vital capacity (VC), and increased diffusing capacity of the lung for @entity1223 to alveolar gas volume. After multiple linear regression analysis, only WC was associated with reductions in FEV1, FVC, @entity358 , and VC. CONCLUSIONS: Obesity is associated with a restrictive pattern of @entity73 in various anthropometric parameters measured in @entity28 Chinese adults in Taiwan. Among these parameters, WC had the greatest impact on pulmonary function, which could also implicate the rate of @entity260 and the need of more intensive care after bariatric surgery.
