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
Objective To understand the intake of soy isoflavones in rural women in China and its relationship with the prevalence of chronic diseases. Methods The prevalence of soybean food consumption and chronic diseases in 1188 rural women in Weichang, Hebei Province and Lanzhou City, Gansu Province were investigated. The average intake of soy isoflavones in rural women was calculated and the prevalence of chronic diseases among healthy women Of soy isoflavone intake. Results The average intake of soy isoflavones in rural women in Weichang County and Lanzhou City was (15 3 ± 18 9) mg d (M 8 8) and 19 5 ± 32 9 mg d (M 10 1), respectively There was a significant difference between the two (P <0 05), and were non-normal distribution. The prevalence of chronic diseases among women in Weichang County was 25.6%, significantly higher than that of Lanzhou City (18.8%). The intake of soy isoflavones in healthy women was (17 8 ± 2 28) mg d (M = 95), higher than that of chronic disease reports (15 7 ± 225) mg d (M = 83) , There was a significant difference between the intake of cardiovascular disease report and gastrointestinal disease report (P <0 05). Conclusions There is an inverse relationship between the intake of soy isoflavones and the prevalence of chronic diseases, suggesting that soy isoflavones may have some preventive effects on chronic diseases
