The California Expanded Food and Nutrition Education program (EFNEP) Evaluation Study evaluated the effectiveness of the California program. The eating habits of 683 persons were studied in a group receiving EFNEP instruction (355 participants) and a control group (328 participants) that received no instruction. The 24-hour food recall was used to assess eating habits using the Synectics method. At the beginning of the study, there were no differences in food recall scores between the EFNEP and the control groups. After 6 months of instruction in the EFNEP group, there was a significant increase in food recall score for that group and no change in the control group. The improvements observed in the EFNEP group resulted from increased intakes from the milk, protein, and fruit and vegetable food groups. The program characteristics that led to those changes were determined to be in the length of the EFNEP visit, the number of EFNEP visits, and the EFNEP instruction topics. These results show that the California EFNEP is effective in producing significant changes in the eating habits of the low-income individuals it serves.
加利福尼亚扩展食品与营养教育计划（EFNEP）评估研究对加利福尼亚州的该计划成效进行了评估。研究了683人的饮食习惯，其中一组接受EFNEP指导（355名参与者），另一组为对照组（328名参与者），后者未接受指导。采用24小时食物回顾法，运用联想法来评估饮食习惯。研究开始时，EFNEP组和对照组的食物回顾得分没有差异。在EFNEP组接受6个月指导后，该组的食物回顾得分显著提高，而对照组没有变化。EFNEP组观察到的改善源于牛奶、蛋白质以及水果和蔬菜食物组的摄入量增加。导致这些变化的计划特征被确定为EFNEP访问的时长、EFNEP访问的次数以及EFNEP指导主题。这些结果表明，加利福尼亚州的EFNEP能够有效地使它所服务的低收入人群的饮食习惯产生显著变化。
