目的了解吉林市健康成年男性膳食异黄酮摄入量与血脂的关系。方法用膳食记录法调查710名20～60岁吉林市部分健康成年男性膳食摄入量,进行体格检查,抽取空腹清晨静脉血测定总胆固醇(TC)、甘油三酯(TG)、低密度脂蛋白胆固醇(LDL-C)、高密度脂蛋白胆固醇(HDL-C)。结果 710名男性大豆异黄酮摄入量为19.8 mg/d。按照异黄酮摄入量将研究对象分低、中、高3组,摄入量分别为(4.2±2.8)mg/d,(13.8±2.5)mg/d和(39.5±17.2)mg/d,3组间差异有统计学意义(P<0.000 1)。控制BMI、能量,脂肪供能比之后,3组间TC(P=0.004)和LDL-C(P=0.000 6)差异有统计学意义。结论膳食大豆异黄酮摄入量有助于健康男性血脂改善。
