【摘要】 目的　为了解我国农村成年女性大豆异黄酮的摄入量及其与慢性疾病患病率的关系。方法　对河北省围场县和甘肃省兰州市 1188名农村女性的大豆食品消费量和慢性疾病患病情况进行调查 ,计算农村女性的大豆异黄酮平均摄入量 ,并分析慢性疾病报告者与健康女性的大豆异黄酮摄入量。结果　围场县和兰州市农村女性的大豆异黄酮平均摄入量分别为 (15 3± 18 9)mg d(M =8 8)和 (19 5± 32 9)mg d(M =10 1) ,两者具有显著性差异 (P <0 0 5 ) ,并均呈非正态分布。围场县女性的慢性疾病报告患病率为 2 5 6 % ,明显高于兰州市 (18 8% )。健康女性的大豆异黄酮摄入量为 (17 8± 2 2 8)mg d(M =9 5 ) ,高于慢性疾病报告者的 (15 7± 2 2 5 )mg d(M =8 3) ,与心血管疾病报告者和消化道疾病报告者的摄入量有显著性差异 (P <0 0 5 )。结论　大豆异黄酮摄入量与慢性疾病患病率呈反比关系 ,暗示了大豆异黄酮可能对慢性疾病具有一定的预防作用更多还原

【Abstract】 To evaluate the average intake of soy isoflavones and the correlation between this intake and prevalence of chronic diseases among Chinese rural women, soy food consumption and medical history of 1188 recruited rural adult women from Weichang County (Hebei Province) and Lanzhou City (Gansu Province) were collected using food frequency questionnaire. The results showed that the intake of soy isoflavones by Weichang and Lanzhou women was (15.3±18.9)mg/d (M=8.8) and (19.5±32.9)mg/d (M=10.1), respectively. There had statistically significant difference (P<0.05). The distribution of soy isoflavones intake was skewed to the right. The reported disease prevalence in Weichang was 25.6% and higher than that in Lanzhou (18.8%). The average intake of soy isoflavones by healthy women was (17.8±22.8)mg/d (M=9.5), which was higher than that by women who reported to have one of chronic diseases [(15.7±22.5)mg/d(M=8.3)]and significantly higher than that by women who reported to have cardiovascular diseases or chronic digestive system diseases (P<0.05). These findings indicated an inverse correlation between soy isoflavones intakes and the prevalence of chronic diseases, suggesting that soy isoflavones may play a potential role in the prevention for chronic diseases.更多还原
