Association between the Body Roundness Index and spirometric parameters among U.S. Adolescents from NHANES 2007–2012
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.

| description | 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. |
