The objective of the present study was to evaluate the effects of the Pro Children intervention on schoolchildren's fruit and vegetable (FV) intake after 1 and 2 years of follow-up. The intervention combined a FV curriculum with efforts to improve FV availability at schools and at home. Effects were examined in a group-randomised trial among 1,472 10-11-year-old children from sixty-two schools in Norway, the Netherlands and Spain. FV intake was assessed by means of validated self-administered questionnaires completed before the intervention (September 2003), immediately after the first year of the intervention (May 2004) and 1 year later (May 2005). Data were analysed using multilevel linear regression analyses with age and sex as covariates. Significant intervention effects for FV intake were found at first follow-up in the total sample. The adjusted FV intake reported by the children from intervention schools was 20 % higher than FV intake reported by children from control schools. At 1 year later, a significant impact was only observed in Norway. Positive intervention effects on FV intake occurred both at school and outside school. We conclude that the Pro Children intervention is a promising means to promote European schoolchildren's FV intakes, but mainly fruit intake, in the short term. As shown in Norway, where the intervention was best implemented, the intervention might also result in longer-term effects. Further strategies need to be developed that can improve implementation, have an impact on vegetable intake and can secure sustained effects.
本研究的目的是评估“关爱儿童”干预措施在随访1年和2年后对学童水果和蔬菜（FV）摄入量的影响。该干预措施将一项FV课程与改善学校和家庭中FV供应的努力相结合。在一项群组随机试验中，对来自挪威、荷兰和西班牙62所学校的1472名10 - 11岁儿童进行了效果检验。FV摄入量通过在干预前（2003年9月）、干预第一年结束后立即（2004年5月）以及1年后（2005年5月）完成的经过验证的自填问卷进行评估。数据分析采用以年龄和性别作为协变量的多水平线性回归分析。在首次随访时，在总样本中发现了FV摄入量的显著干预效果。干预学校儿童报告的调整后FV摄入量比对照学校儿童报告的FV摄入量高20%。1年后，仅在挪威观察到显著影响。对FV摄入量的积极干预效果在学校内外均有出现。我们得出结论，“关爱儿童”干预措施是短期内促进欧洲学童FV摄入量（但主要是水果摄入量）的一种有前景的手段。如在干预实施得最好的挪威所示，该干预措施也可能产生长期效果。需要制定进一步的策略，以改善实施情况、对蔬菜摄入量产生影响并确保持续效果。
