BMC MED:睾酮治疗会对男性节食减肥产生什么影响?

2016-10-15 MedSci MedSci原创

对于节食减肥的肥胖男性,如果加入睾酮治疗,会对减肥效果产生什么影响呢? 我们在一个三级转诊中心进行了一项随机双盲、平行、安慰剂对照试验。共纳入了100名肥胖男性(BMI ≥ 30 kg/m2),总睾酮水平低于12 nmol/L的,中位数年龄53年(四分位距为47–60),接受长达10周的极低能量饮食(VLED),随后体重维持46周。将这些患者随机分到每周肌肉注射十一酸睾酮,进行10周(n=4

对于节食减肥的肥胖男性,如果加入睾酮治疗,会对减肥效果产生什么影响呢?

我们在一个三级转诊中心进行了一项随机双盲、平行、安慰剂对照试验。共纳入了100名肥胖男性(BMI ≥ 30 kg/m2),总睾酮水平低于12 nmol/L的,中位数年龄53年(四分位距为47–60),接受长达10周的极低能量饮食(VLED),随后体重维持46周。将这些患者随机分到每周肌肉注射十一酸睾酮,进行10周(n=49,试验组)或匹配安慰剂组(n=51,对照组)。主要测量指标是双能X线骨密度仪测量的脂肪和瘦肉的组间差异,以及CT测量的内脏脂肪面积差异。

总共有82个人完成了这项研究。在研究结束时,与对照组相比,试验组患者的脂肪量降低更明显,校正后组间的平均差异(MAD)是 –2.9 kg (–5.7 to –0.2; P = 0.04),内脏脂肪的组间平均差异为 –2678 mm2(–5180 to –176; P = 0.04)。虽然VLED后两组失去了相同的瘦体重(试验组 –3.9 kg [–5.3 to –2.6];对照组 –4.8 kg [–6.2 to –3.5], P = 0.36),不过在体重维持期,试验组的瘦体重得以恢复(3.3 kg [1.9 to 4.7], P < 0.001),而对照组则没有(0.8 kg [–0.7 to 2.3], P = 0.29),所以在研究结束的时候,试验组瘦体重的减少程度与对照组相比是衰减的(MAD 3.4 kg [1.3 to 5.5], P = 0.002)。

结果表明,安慰剂组的单纯节食会让肥胖男性同时失去脂肪和瘦体重,但是节食的同时予以睾酮治疗,则肥胖男性几乎只失去体内脂肪。

睾酮替代治疗,让男性重振雄风!
