目的评价绝经前妇女对大豆饮食的依从性。设计为期2年的随机饮食干预的第一年。受试者220名健康的绝经前妇女，报告基线大豆摄入量低。干预：5次咨询拜访，7次随访电话，12次小组会议。主要观察指标：自报大豆摄入日志；食物频率问卷；重复的、随机定时的24小时召回；用高压液相色谱法分析尿异黄酮排泄。统计分析频率分布、均值、t检验和混合效应模型。结果在基线时，两组在膳食大豆摄入量（P= 0.51）和尿异黄酮排泄（P= 0.16）方面没有差异。根据24小时的召回和食物频率问卷调查，干预组的估计异黄酮摄入量比基线和对照组增加了10倍以上(P
Objective To evaluate adherence to a soy-based diet among,premenopausal women.Design First year of a 2-year, randomized dietary intervention.Subjects 220 healthy premenopausal women who reported low baseline soy intake.Intervention 5 counseling visits, 7 follow-up phone calls, and 12 group meetings.Main outcome measures Self-reported soy intake logs; food frequency questionnaires; repeated, randomly timed 24-hour recalls; and analysis of urinary isoflavone excretion by high-pressure liquid chromatography.Statistical analyses Frequency distributions, means, t tests, And mixed effects models.Results At baseline, the 2 groups did not differ in dietary soy intake (P=.51) or urinary isoflavone excretion (P=.16). According to the 24-hour recalls and the food frequency questionnaires, the intervention group's estimated isoflavone intake increased more than 10 times compared with baseline and with the control group (P
