Abstract
Objectives: The association between obesity parameters and lung function indicators in general Chinese rural adult population is still unclear. Methods: A total of 8,284 Chinese adults aged 20 to 80 years old from Xinxiang were recruited in this study. Obesity parameters including body mass index (BMI), waist circumference (WC), hip circumference (HC), waist hip ratio (WHR), waist height ratio (WHtR), body fat percentage (BFP), basal metabolism (BM), and visceral fat index (VFI) and lung function parameters such as forced vital capacity (FVC) and forced expiratory volume in 1 s (FEV1) were measured according to previous guidance. Results: The total prevalence of obesity defined by BMI, WC, WHR, WHtR, and BFP were 23.2%, 58.2%, 66.7%, 69.2%, and 56.5%. Levels of FVC and FEV1 in participants were 3.19 ± 0.72 (L) and 2.68 ± 0.64 (L), respectively. Obesity is obvious and more closely in relation to lung function in women. Lung function levels in the obesity group were lower than those in non-obesity group. Spearman correlation analyses showed that all of the above-mentioned obesity parameters were significantly correlated with lung function levels such as FVC and FEV1. Linear regression analyses further demonstrated that BMI, WHtR, BFP, and general obesity defined by them were negatively associated with lung function, while WC, WHR, and their defined central obesity were positively associated with lung function. In general, the results of the gender stratification analysis showed that the relationship between general obesity and lung function was more evident in women than in men, while the link between central obesity and lung function was more obvious in men than in women. Conclusion: Taken together, obesity status is closely related to lung function in general Chinese adult population. Weight control and loss is an important strategy to improve lung function and respiratory health status.
