We describe the development and implementation of the Pathways school food service intervention during the feasibility phase of the Pathways study. The purpose of the intervention was to lower the amount of fat in school meals to 30% of energy to promote obesity prevention in third- through fifth-grade students. The Pathways nutrition staff and the food service intervention staff worked together to develop 5 interrelated components to implement the intervention. These components were nutrient guidelines, 8 skill-building behavioral guidelines, hands-on materials, twice yearly trainings, and monthly visits to the kitchens by the Pathways nutrition staff. The components were developed and implemented over 18 mo in a pilot intervention in 4 schools. The results of an initial process evaluation showed that 3 of the 4 schools had implemented 6 of the 8 behavioral guidelines. In an analysis of 5 d of school menus from 3 control schools, the lunch menus averaged from 34% to 40% of energy from fat; when the menus were analyzed by using the food preparation and serving methods in the behavioral guidelines, they averaged 31% of energy from total fat. This unique approach of 5 interrelated food service intervention components was accepted in the schools and is now being implemented in the full-scale phase of the Pathways study in 40 schools for 5 y.
我们描述了“路径”学校食品服务干预措施在“路径”研究可行性阶段的开发与实施情况。该干预措施的目的是将学校膳食中的脂肪含量降低至能量的30%,以促进三至五年级学生预防肥胖。“路径”营养工作人员和食品服务干预工作人员共同努力,制定了5个相互关联的组成部分来实施该干预措施。这些组成部分包括营养指南、8条技能培养行为准则、实践材料、每年两次培训以及“路径”营养工作人员每月对厨房的走访。这些组成部分在4所学校的试点干预中历经18个月得以开发和实施。初步过程评估结果显示,4所学校中有3所实施了8条行为准则中的6条。在对3所对照学校5天的学校菜单进行分析时,午餐菜单中脂肪提供的能量平均占34%至40%;当按照行为准则中的食物制备和供应方法对菜单进行分析时,它们的总脂肪能量平均占31%。这种由5个相互关联的食品服务干预组成部分构成的独特方法在学校中得到了认可,目前正在“路径”研究的全面实施阶段在40所学校推行,为期5年。
