This is the first study to evaluate directly visceral fat area (VFA) using a visceral fat (VF) meter by the abdominal bioelectrical impedance analysis (A-BIA) method in obstructive sleep apnea (OSA) patients diagnosed with polysomnography (PSG). The purpose of this study is to clarify (1) whether VFA measurement using a VF meter by the A-BIA method is possible even in a private clinic without burdening patients and staff and (2) how much VFA affects OSA compared to body mass index (BMI). Even without a computed tomography scan, which is the gold standard for VFA measurement, a VF meter could analyze patients by the A-BIA method and easily measure VFA. Therefore, it could be used safely even in a private sleep clinic, with very little burden on the patients and the medical staff. We investigated the association between OSA and VFA in 133 OSA patients. Multiple regression analysis revealed that VFA (β = 0.28; P = 0.020) was a stronger coexisting factor for OSA than age, male gender, or BMI (β = 0.26; P = 0.032) in all OSA patients. In the OSA patients with VF accumulation, only VFA was a significant component of OSA severity (β = 0.36; P = 0.006). The A-BIA method instrument could become a useful device for the evaluation of VF accumulation in OSA patients in private sleep clinics. VF accumulation should be recognized as an important risk factor as well as a known risk factor for OSA.

这是第一项使用内脏脂肪 (VF) 计通过腹部生物电阻抗分析 (A-BIA) 方法直接评估诊断为多导睡眠图 (PSG) 的阻塞性睡眠呼吸暂停 (OSA) 患者的内脏脂肪面积 (VFA) 的研究。本研究的目的是阐明 (1) 即使在不给患者和工作人员带来负担的情况下，使用 A-BIA 方法使用 VF 测量仪测量 VFA 是否可行，以及 (2) 与体重指数相比，VFA 对 OSA 的影响有多大(BMI)。即使没有作为 VFA 测量黄金标准的计算机断层扫描，VF 计也可以通过 A-BIA 方法分析患者并轻松测量 VFA。因此，即使在私人睡眠诊所也可以安全使用，对患者和医务人员的负担很小。我们在 133 名 OSA 患者中调查了 OSA 和 VFA 之间的关联。多元回归分析显示 VFA (β = 0.28;在所有 OSA 患者中，P = 0.020）是比年龄、男性或 BMI（β = 0.26；P = 0.032）更强的 OSA 共存因素。在 VF 积累的 OSA 患者中，只有 VFA 是 OSA 严重程度的重要组成部分（β = 0.36；P = 0.006）。A-BIA 方法仪器可以成为评估私人睡眠诊所 OSA 患者 VF 积累的有用设备。VF 积累应被视为 OSA 的一个重要风险因素以及已知的风险因素。
