Abstract
OBJECTIVES
The association between obesity parameters and lung function indicators in the general Chinese rural adult population remains unclear.
METHODS
In total, 8,284 Chinese adults aged 20 years to 80 years old from Xinxiang were recruited. Obesity-related parameters, including body mass index (BMI), waist circumference (WC), hip circumference (HC), waist-to-hip ratio (WHR), waistto-height ratio (WHtR), body fat percentage (BFP), basal metabolism, and visceral fat index, and lung function parameters such as forced vital capacity and forced expiratory volume in first second were measured.
RESULTS
The total prevalence of obesity defined by BMI, WC, WHR, WHtR, and BFP was 23.2%, 58.2%, 66.7%, 69.2%, and 56.5%, respectively. Spearman correlation analyses showed significant correlations between all obesity-related parameters and lung function. Linear regression analyses further demonstrated that BMI, WHtR, BFP, and general obesity defined using those indicators were negatively associated with lung function, while WC, WHR, and central obesity defined accordingly were positively associated with lung function. 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.
CONCLUSIONS
Obesity is closely related to lung function in the general Chinese adult population. Weight control and loss are important strategies to improve lung function and respiratory health.
Summary
Korean summary
Key Message
This cross-sectional sduty clarify the relationship between several obesity parameters and lung function indicators on rural adult population in central China using big data and stratified analyses. Specifically, the obesity group has a lower level of lung function than the non-obesity group, and there is an opposite effect of general obesity and central obesity on lung function.
