The Cafeteria Power Plus project examined whether a cafeteria-based intervention would increase the fruit and vegetable (FV) consumption of children. Twenty-six schools were randomly assigned to either an intervention or control condition. Baseline lunch observations of a sample (N = 1668) of first- and third-grade students occurred in the spring of 2000; follow-up was in the spring of 2002. The intervention took place during two consecutive school years beginning in the fall of 2000 and consisted of daily activities (increasing the availability, attractiveness, and encouragement for FV) and special events (kick-offs, samplings, challenge weeks, theater production, and finale meal). Training of food-service staff and cook managers was ongoing throughout the intervention phase. Students in the intervention schools significantly increased their total fruit intake. Process measures indicated that verbal encouragement by food-service staff was associated with outcomes. The outcomes suggest that multicomponent interventions are more powerful than cafeteria programs alone with this age group.
“自助餐厅强化动力”项目研究了以自助餐厅为基础的干预措施是否会增加儿童的水果和蔬菜摄入量。26所学校被随机分为干预组或对照组。2000年春季对一、三年级学生样本（N = 1668）进行了基线午餐观察；随访在2002年春季进行。干预从2000年秋季开始，持续两个连续学年，包括日常活动（增加水果和蔬菜的供应、吸引力并给予鼓励）和特别活动（启动仪式、样品品尝、挑战周、戏剧表演和结业餐）。在整个干预阶段，一直在对食品服务人员和厨师经理进行培训。干预学校的学生水果总摄入量显著增加。过程指标表明，食品服务人员的口头鼓励与结果相关。结果表明，对于这个年龄组，多成分干预比单纯的自助餐厅项目更有效。
