A randomized school based trial sought to increase fruit and vegetable consumption among children using a multicomponent approach.
The intervention, conducted in 20 elementary schools in St. Paul, targeted a multiethnic group of children who were in the fourth grade in spring 1995 and the fifth grade in fall 1995. The intervention consisted of behavioral curricula in classrooms, parental involvement, school food service changes, and industry support and involvement. Lunchroom observations and 24-hour food recalls measured food consumption. Parent telephone surveys and a health behavior questionnaire measured psychosocial factors.
The intervention increased lunchtime fruit consumption and combined fruit and vegetable consumption, lunchtime vegetable consumption among girls, and daily fruit consumption as well as the proportion of total daily calories attributable to fruits and vegetables.
Multicomponent school-based programs can increase fruit and vegetable consumption among children. Greater involvement of parents and more attention to increasing vegetable consumption, especially among boys, remain challenges in future intervention research.
一项基于学校的随机试验试图采用多组分方法增加儿童的水果和蔬菜摄入量。
该干预措施在圣保罗的20所小学实施，目标群体是1995年春季四年级、1995年秋季五年级的多民族儿童。干预措施包括课堂行为课程、家长参与、学校食品服务改革以及行业支持与参与。通过食堂观察和24小时食物回顾来测量食物摄入量。通过家长电话调查和健康行为问卷来测量社会心理因素。
该干预措施增加了午餐时间的水果摄入量以及水果和蔬菜的总摄入量、女孩午餐时间的蔬菜摄入量、每日水果摄入量以及水果和蔬菜在每日总热量中所占的比例。
基于学校的多组分项目可以增加儿童的水果和蔬菜摄入量。家长更多地参与以及更加关注增加蔬菜摄入量，尤其是男孩的蔬菜摄入量，在未来的干预研究中仍然是挑战。
