CDS 2014:东西方胰岛素抵抗是否存在差异?

2014-11-10 中山大学孙逸仙纪念医院 李焱 中国医学论坛报

胰岛素抵抗,如何产生? 随着生活水平提高、体力活动减少,超重和肥胖人群明显增加,同时胰岛素抵抗的发生率也在升高。发生胰岛素抵抗时胰岛素作用减弱,血葡萄糖进入组织减少。如果胰岛素分泌代偿性增加足以维持血糖正常,则出现高胰岛素血症;如果胰岛素分泌不足以克服胰岛素抵抗对血糖的影响,则出现2型糖尿病。超重或肥胖者出现胰岛素抵抗是一种机体自我保护机制,以避免过多能量物质进入细胞。 东

胰岛素抵抗,如何产生?

随着生活水平提高、体力活动减少,超重和肥胖人群明显增加,同时胰岛素抵抗的发生率也在升高。发生胰岛素抵抗时胰岛素作用减弱,血葡萄糖进入组织减少。如果胰岛素分泌代偿性增加足以维持血糖正常,则出现高胰岛素血症;如果胰岛素分泌不足以克服胰岛素抵抗对血糖的影响,则出现2型糖尿病。超重或肥胖者出现胰岛素抵抗是一种机体自我保护机制,以避免过多能量物质进入细胞。

东西方是否有差异?研究结论不一

就发生机制和自然病程而言,目前的证据尚不能确定东西方人群的胰岛素抵抗是否存在差异。不同研究得出的结论不同。有研究显示,东西方人群,主要是高加索人与东亚人的胰岛素抵抗存在差异,高加索人的胰岛素抵抗更明显;但也有研究认为东亚人尤其是亚裔美国人比高加索人胰岛素抵抗更明显;另外的一些研究结果则显示两个种族之间没有区别。研究结果多样性的原因尚不明确,可能与研究对象选择标准、评估胰岛素抵抗的方法、不同混杂因素的校正等多种差异有关。

荟萃分析的结果提示,东亚人群的胰岛素抵抗程度与高加索人有较大重叠。在所有研究人群中,东亚人体质指数(BMI)均较高加索人低,糖调节正常的东亚人胰岛素敏感性更好;但在糖调节异常人群和2型糖尿病人群,东亚人和高加索人的胰岛素敏感性没有显著区别。
