Abstract:

Background

The body roundness index (BRI) is an emerging anthropometric indicator that has been increasingly associated with various cardiometabolic conditions, including hypertension and diabetes. However, its association with obstructive sleep apnea (OSA) and its potential as a predictive tool remain poorly understood.

Objective

This study aimed to investigate the association between BRI and OSA risk and to evaluate its predictive performance for OSA in adults.

Methods

A cross-sectional analysis was conducted among 638 outpatients suspected of OSA at Shenzhen University Affiliated South China Hospital between January 2024 and March 2025. All participants underwent overnight polysomnography, and OSA was defined as an apnea-hypopnea index (AHI) ≥ 5 events per hour. Anthropometric measurements—including height, weight, waist circumference, and neck circumference were collected to calculate BRI, BMI, a body shape index (ABSI), and weight-adjusted waist index (WWI). Multivariable Logistic regression models were used to assess the association between BRI and OSA after adjusting for potential confounders. Receiver operating characteristic (ROC) curves were constructed to compare the diagnostic accuracy of each index, with subgroup analyses performed by sex.

Results

Of the 638 participants, 552 (86.5%) were diagnosed with OSA. The multivariable Logistic regression revealed a significant dose-response relationship between BRI and OSA risk (Ptrend<0.001). After adjusting for confounding factors, the risk of OSA in the highest quartile group of BRI (Q4: >5.744) was 6.955 times (95%CI=2.960-16.344) that of the lowest group (Q1: ≤3.931). The ROC analysis demonstrated that BRI achieved an area under the curve (AUC) of 0.740 (95%CI=0.682-0.799) for OSA detection, with an optimal cut-off value of 4.199 yielding 73.4% sensitivity and 68.6% specificity. In comparison, the AUC for ABSI, WWI, and BMI were 0.633, 0.676, and 0.717, respectively. DeLong test results confirmed that BRI's AUC was greater than those of ABSI and WWI (P<0.05). In men, the AUC of BRI in diagnosing OSA was 0.774. In women, the AUC of BRI in diagnosing OSA was 0.654.

Conclusion

BRI serves as a significant influencing factor for the prevalence of OSA among Chinese adults, demonstrating good predictive efficacy. Consequently, BRI can be utilized as an economical and effective tool for the early screening of OSA.

摘要: 背景 身体圆度指数(BRI)是一种新兴的人体测量指标,近年来被认为与多种疾病如高血压、糖尿病相关,但其与阻塞性睡眠呼吸暂停(OSA)患病的关系及预测价值目前尚不明确。目的 探讨BRI与OSA患病风险的相关性及其预测价值。方法 采用横断面研究设计,纳入2024年1月—2025年3月深圳大学附属华南医院门诊疑似OSA患者638例,通过整夜睡眠监测确诊OSA(呼吸暂停低通气指数≥5次/h)。采集人体测量指标(身高、体质量、腰围、颈围)等,计算BRI、BMI、身材指数(ABSI)及体质量校正腰围指数(WWI)。采用多因素Logistic回归分析探究BRI与OSA的关联性,通过受试者工作特征(ROC)曲线比较各指标对OSA的预测效能,并分性别进行亚组分析。结果 638例研究对象中,确诊OSA 552例,非OSA 86例。多因素Logistic回归分析结果显示,随BRI四分位数升高,OSA患病风险显著递增(P趋势<0.001);调整混杂因素后,BRI最高分位数组(Q4:>5.744)的OSA风险为最低组(Q1:≤3.931)的6.955倍(95%CI=2.960~16.344)。ROC曲线显示,BRI诊断OSA的ROC曲线下面积(AUC)为0.740(95%CI=0.682~0.799),最佳截断值为4.199(灵敏度为73.4%,特异度为68.6%),ABSI、WWI、BMI诊断OSA的AUC值分别为0.633、0.676、0.717,DeLong检验结果显示,BRI预测OSA的AUC大于ABSI、WWI(P<0.05)。在男性中,BRI诊断OSA的AUC为0.774;在女性中,BRI诊断OSA的AUC为0.654。结论 BRI是中国成人OSA的患病影响因素,其预测效能较好,BRI可作为OSA早期筛查的经济、有效工具。
