Metabolic syndrome is a risk factor for age-related hearing impairment (ARHI). There are metabolic differences between abdominal adipose tissue present in subcutaneous and visceral areas. In this study, we investigated the association between abdominal fat composition, measured by computerized tomography (CT), and hearing thresholds.
We recruited 662 adults aged 40-82 years with normal or symmetrical sensorineural hearing loss who underwent fat measurement by CT. Linear regression models were used to address the association between risk factors, including abdominal fat composition, and average hearing levels at low and high frequencies.
After adjusting for age, systemic disease and other variables, a positive association between visceral adipose tissue (VAT) area and average hearing threshold was observed in women. In men, there was no significant association between abdominal fat composition and hearing threshold.
Our findings show an association between VAT and hearing impairment in women. A reduction in visceral adiposity may help to prevent hearing loss in women.
代谢综合征是与年龄相关的听力损伤（ARHI）的一个风险因素。腹部脂肪在皮下和内脏区域存在代谢差异。在这项研究中，我们研究了通过计算机断层扫描（CT）测量的腹部脂肪组成与听力阈值之间的关系。
我们招募了 662 名年龄在 40-82 岁之间、具有正常或对称感音神经性听力损失的成年人，这些人通过 CT 进行了脂肪测量。线性回归模型用于解决包括腹部脂肪组成在内的风险因素与低频和高频平均听力水平之间的关联。
在调整了年龄、系统性疾病和其他变量后，女性的内脏脂肪组织（VAT）面积与平均听力阈值之间存在正相关。在男性中，腹部脂肪组成与听力阈值之间没有显著关联。
我们的研究结果表明 VAT 与女性听力损伤之间存在关联。减少内脏脂肪可能有助于预防女性听力损失。
