| Summary: | Abstract Background Obesity is an important factor affecting pulmonary function. The Body Roundness Index (BRI) is a new method of assessing body and visceral adiposity, but its association with spirometric parameters in adolescents has not been previously reported. Methods Cross-sectional data were obtained from the 2007 to 2012 National Health and Nutrition Examination Survey (NHANES), with participants having complete data on BRI and spirometric parameters. A generalized linear regression was conducted to explore the independent relationship between BRI and spirometric parameters. Smoothing curve fitting, subgroup analysis, and interaction tests were also performed. Results A negative correlation was observed between BRI and pulmonary function. In the fully adjusted model, an increase of one unit in BRI was associated with an increase of 0.08 L in FVC, an increase of 0.04 L in FEV1, an increase of 5.17 L/min in PEF, and a decrease of 0.62% in FEV1/FVC. Conclusion The results suggest an inverse association between BRI and pulmonary function. However, the clinical significance of this finding warrants further study. Clinical trial number Not applicable. |
