背景儿童和青少年心血管健康试验（CATCH）测试了旨在促进健康的学校环境和儿童积极饮食和体育活动行为的多层次干预的有效性。CATCH Eat Smart计划针对学校食品服务人员，旨在降低学校膳食中的总脂肪、饱和脂肪和钠含量。在两年半的时间里，在56所干预学校进行了明智饮食干预。在1991年秋季、1993年春季和1994年春季三个时间段，从干预和对照学校收集了连续五天的学校菜单、食谱和供应商产品信息，以评估学校菜单的营养成分。与对照学校相比，从基线到随访，干预学校的总脂肪（校正平均差异-4.1%; P < 0.0001）和饱和脂肪（校正平均差异-1.3%; P = 0.003）的卡路里百分比平均降低幅度更大。尽管在两种情况下学校午餐的钠含量都有所增加，但干预学校的平均增幅明显较低（校正后的平均差异为-89 mg;P = 0.034）。胆固醇、碳水化合物、蛋白质、膳食纤维、总糖、钙、铁、维生素A值和维生素C的总量无统计学显著差异。平均总热量显著下降;然而，干预学校的平均总热量（683千卡）仍然高于该年龄组推荐膳食津贴的三分之一。CATCH Eat Smart干预措施成功地降低了学校午餐的总脂肪和饱和脂肪含量，同时保持了推荐的卡路里和必需营养素含量。(C)出版社：Academic Press，Inc.
Background. The Child and Adolescent Trial for Cardiovascular Health (CATCH) tested the effectiveness of a multilevel intervention aimed at promoting a healthful school environment and positive eating and physical activity behaviors in children. The CATCH Eat Smart Program targeted the school food service staff and aimed to lower the total fat, saturated fat, and sodium content of school meals.Methods. The Eat Smart intervention was conducted in 56 intervention schools over a 2 1/2-year period. Five consecutive days of school menu, recipe, and vendor product information were collected from intervention and control schools at three intervals, Fall 1991, Spring 1993, and Spring 1994, to assess the nutrient content of school menus as offered.Results. There was a significantly greater mean reduction in the percentage of calories from total fat (adjusted mean difference -4.1%; P < 0.0001) and saturated fat (adjusted mean difference -1.3%; P = 0.003) in intervention compared with control schools from baseline to follow-up. Although the sodium content of school lunches increased in both conditions, the mean increase was significantly lower in intervention schools (adjusted mean difference -89 mg;P = 0.034). There were no statistically significant differences for total amounts of cholesterol, carbohydrate, protein, dietary fiber, total sugars, calcium, iron, vitamin A value, and vitamin C. Average total calories decreased significantly; however, the mean total calories (683 kcal) for intervention schools remained above one-third of the Recommended Dietary Allowances for this age group.Conclusions. The CATCH Eat Smart intervention successfully lowered the total fat and saturated fat content of school lunches as offered, while maintaining recommended amounts of calories and essential nutrients.
