背景目前的癌症预防建议包括减少脂肪的消耗和增加水果和蔬菜的消耗。健康女性健康维护组织成员（n = 616）年龄40 - 70被随机分配到营养干预或控制干预无关的饮食。干预包括两个45分钟的咨询会议，加上两个简短的后续电话联系。咨询会议包括20分钟，互动，基于计算机的干预使用触摸屏格式。干预目标是减少膳食脂肪和增加水果和蔬菜的消费。结果测量包括食物频率问卷和脂肪和纤维行为问卷（FFBQ）。在基线和12个月时也测量血清总胆固醇。10个月的随访数据显示，所有饮食结果变量均有所改善。与对照组相比，干预参与者报告脂肪消耗量显著减少（脂肪能量百分比减少3.75分），水果和蔬菜的摄入量显著增加（每天多0.93份），脂肪消耗行为指标显著减少（FFBQ变化0.20分）。血清总胆固醇的组间差异，虽然在预期的方向，但并不显著。在适当的情况下，中等强度的饮食干预可以在至少一年的时间内显示出显着的效果。(C)2003年美国健康基金会和爱思唯尔科学（美国）。All rights reserved.
Background. Current cancer prevention recommendations include reducing consumption of fat and increasing consumption of fruits and vegetables.Methods. Healthy women health maintenance organization members (n = 616) ages 40-70 were randomly assigned to either a nutrition intervention or a control intervention unrelated to diet. Intervention included two 45-min counseling sessions plus two brief follow-up telephone contacts. Counseling sessions included a 20-min, interactive, computer-based intervention using a touch-screen format. Intervention goals were reducing dietary fat and increasing fruit and vegetable consumption. Outcome measures included a food frequency questionnaire and the Fat and Fiber Behavior Questionnaire (FFBQ). Total serum cholesterol was also measured at baseline and 12 months.Results. Twelve-month follow-up data showed improvements on all dietary outcome variables. Compared to the control, intervention participants reported significantly less fat consumption (3.75 points less for percentage of energy from fat), significantly greater consumption of fruit and vegetables combined (0.93 more servings per day), and a significant reduction in a behavioral measure of fat consumption (0.20 point change in the FFBQ). Group differences in total serum cholesterol, while in the desired direction, were not significant.Conclusions. In appropriate circumstances, moderate-intensity dietary interventions can show significant effects for periods of at least 1 year. (C) 2003 American Health Foundation and Elsevier Science (USA).
