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.

NHANES 2007-2012中美国青少年体圆度指数和肺活量测定参数之间的关系

背景：肥胖是影响肺功能的重要因素。身体圆度指数（BRI）是一种评估身体和内脏脂肪的新方法，但其与青少年肺活量测定参数的关联此前尚未报道。方法：从2007 - 2012年全国健康与营养调查（NHANES）中获得横断面数据，参与者具有完整的BRI和肺活量测定参数数据。采用广义线性回归来探讨BRI与肺活量测定参数之间的独立关系。并进行平滑曲线拟合、亚组分析和交互作用检验。结果：BRI与肺功能呈负相关。在完全调整模型中，BRI每增加1个单位，FVC增加0.08 L， FEV1增加0.04 L， PEF增加5.17 L/min， FEV1/FVC降低0.62%。结论：BRI与肺功能呈负相关。然而，这一发现的临床意义值得进一步研究。临床试验号：不适用。
