Gastroenterology:腹内脂肪含量差异与代谢综合征风险

2019-03-14 MedSci MedSci原创

研究认为不同族裔和种族群体在腹内脂肪含量存在广泛差异,并导致代谢综合征风险差异

近日研究人员通过比较了5个不同种族群体中腹部脂肪含量,以考察脂肪储存是否与代谢综合征和其他肥胖相关疾病相关。

研究收集了1794名年龄在60-77岁的多民族群体参与者数据(非洲人、白人欧洲人、日本人、拉丁美洲人或夏威夷土著人),其体重指数17.1-46.2 kg/m2。采用双能x线吸收计量法和腹部磁共振成像对受试者腹部脂肪含量进行评估,评估了成人体重变化与腹壁多脂症的关系以及由腹壁多脂症引起的代谢综合征的发生率。

躯干、内脏和肝脏脂肪含量在不同种族间有显著差异,其中日裔美国人最高,非裔美国人中最低,其他群体中居中。与非洲裔美国人相比,美国日裔男性和女性的平均内脏脂肪面积分别为高出45%和73%,然而在美国日裔男性和女性中肝脏脂肪的平均测量值分别高出61%和122%。21岁以后,参与者内脏和肝脏脂肪与体重增加有关。与白种人相比,非裔美国人、日裔美国人和夏威夷土著女性在代谢综合征患病率方面的差异是由于内脏脂肪和肝脏脂肪共同占比导致的,而与脂肪总量无关。

研究认为不同族裔和种族群体在腹内脂肪含量存在广泛差异,并导致代谢综合征风险差异。
