Pathways was a multisite, multicomponent obesity prevention intervention for American-Indian schoolchildren. The goal of the school breakfast and lunch component was to reduce fat content of school meals to 30% or fewer calories from fat without compromising dietary quality.
An intensive 3-year intervention was implemented with school food service staff. Five consecutive days of school breakfast menu and recipe information was collected at 20 control and 19 intervention schools at four time intervals. Data were analyzed at nutrient and (in final year) food levels.
Average total fat decreased in intervention schools from 16.0 grams at baseline to 13.6 grams by end of study, compared with 16.6 and 16.7 grams at baseline and final measurement in control schools (P<0.030). Percentage of calories from saturated fat were also significantly reduced from 12.0 to 8.9%, compared with 12.1 to 10.6% in control schools (P<0.014). There were no significant differences in total energy or other nutrients by treatment condition across four time points. Food-level data revealed a consistent pattern of more lower-fat items served in intervention schools compared to control schools.
Pathways was successful in achieving its overall goal of reducing dietary fat in meals served for school breakfasts.
“途径”项目是一项针对美国印第安学童的多地点、多组成部分的肥胖预防干预措施。学校早餐和午餐部分的目标是将学校膳食中的脂肪含量降低至占卡路里的30%或更少,同时不影响膳食质量。
对学校食品服务人员实施了为期3年的强化干预。在20所对照学校和19所干预学校,分四个时间间隔收集了连续五天的学校早餐菜单和食谱信息。在营养素水平以及(最后一年)食品水平上对数据进行了分析。
干预学校的平均总脂肪量从基线时的16.0克降至研究结束时的13.6克,而对照学校在基线和最终测量时分别为16.6克和16.7克(P<0.030)。饱和脂肪提供的卡路里百分比也从12.0%显著降至8.9%,而对照学校为12.1%至10.6%(P<0.014)。在四个时间点上,不同处理条件下的总能量或其他营养素没有显著差异。食品水平数据显示,与对照学校相比,干预学校提供的低脂食品种类始终更多。
“途径”项目成功实现了降低学校早餐膳食中脂肪含量的总体目标。
