遗传背景对2型糖尿病患者膳食干预效果的影响

目的 探讨2型糖尿病(T2DM)患者遗传素质对膳食干预效果的影响,为T2DM患者制定个体化的膳食干预措施提供科学依据.方法 随机抽取T2DM新发病例378例,对其进行膳食干预;将完成干预的342例T2DMFPG水平达正常的155例确定为干预有效组(A组);FPG水平从未正常或者偶尔正常的187例确定为干预无效组(B组).检测并比较两组T2DM患者的血脂水平和LPL基因S447变异的发生频率.结果 A、B两组研究对象在性别、年龄、种族、地区及饮食干预措施和膳食干预前两组患者的空腹血糖、血脂等代谢指标差别均无显著性(P>0.05);但A组和B组人群LPLS447基因型构成及等位基因频率分别为(S/S:76.13%,S/X:21.94%,X/X:1.93%;S:87.10%,X:12.90%)和(S/S:87.70%,S/X:11.77%,X/X:0.53%;S:93.58%,X:6.42%),差别有显著性(χ2=7.845,P=0.005;χ2=8.408,P=0.004).结论 T2DM人群膳食干预效果受自身遗传素质的影响;膳食干预对LPLS/X及X/X基因型患者较S/S基因型患者效果明显.提示在对T2DM患者进行饮食干预时要因人而已,针对不同遗传背景的患者应实施个体化的干预措施,以减少治疗盲目性,提高干预效果.

The influence of differert backgrounds of heredity on effect of dietary intervention to type 2 diabetics

Objective To explore the influence of individual heredity diathesis on effect of dietary behavior intervention in type 2 diabetic populations,so as to provide scientific evidence for establishing more individual dietary intervention measures for type 2 diabetes patients,lessen the aimlessness in treatment,heighten effect of intervention.Methods 378 new type 2 diabetes mellitus cases were randomly selected from center of disease control and prevention(CDC) of Liangshan Shandong province between years of sep....
