Stroke:血清瘦素能降低卒中发生风险?

2015-09-07 phylis 译 MedSci原创

背景和目的:血清瘦素是调节体重平衡和能量代谢的主要脂肪素。血清瘦素水平与卒中发生风险的关系认识尚不一致。我们主要是为了验证血清瘦素水平与老年人卒中发生的风险相关这一假说。方法:对非卒中受试者757人血清瘦素水平进行检测,受试者(平均年龄79岁,62%女性)是第22个检验周期(1990-1994)中的Framingham研究组中的成员。确定受试者所有脑卒中以及缺血性卒中的发生。结果:平均随访时间10

背景和目的:血清瘦素是调节体重平衡和能量代谢的主要脂肪素。血清瘦素水平与卒中发生风险的关系认识尚不一致。研究人员的研究主要是为了验证血清瘦素水平与老年人卒中发生的风险相关这一假说。

方法:对非卒中受试者757人血清瘦素水平进行检测,受试者(平均年龄79岁,62%女性)是第22个检验周期(1990-1994)中的Framingham研究组中的成员。确定受试者所有脑卒中以及缺血性卒中的发生。

结果:平均随访时间10年,期间119名受试者患有卒中(99名为缺血性卒中)。在多变量Cox回归模型中,血清瘦素的对数值与所有脑卒中或者缺血性脑卒中不存在相关(每增加1个SD的HR分别为:0.90 [0.73-1.09] ;0.89 [0.72-1.11])。相应结果表明血清瘦素水平与脑卒中之间的相关性应用腰臀比进行效应修饰。校正年龄、性别以及存在的卒中危险因素后,分层分析腰臀比,显示仅在腰臀比值前四分之一的人群中,较低的所有脑卒中以及缺血性脑卒中的发生率与较高的血清瘦素水平相关(所有脑卒中HR值:0.64 [0.43, 0.95] VS 0.98 [0.77, 1.25] 缺血性脑卒中HR值  0.61 [0.39, 0.95] VS 0.96 [0.74, 1.26])。

结论:血清瘦素水平与卒中发生的风险不直接相关,但在腰臀比值前四分之一的人群中血清瘦素水平与卒中发生风险存在负相关。需要进一步研究证实这些研究结果,并探索这种相关性潜在的发生机制。
