Unhealthy lifestyles contribute to the development of cardiovascular risk factors, whose incidence is increasing among children and adolescents. The Program SI! is a long-term, multi-target behavioral intervention to promote healthy lifestyle habits in children through the school environment. The objective of the study is to evaluate the efficacy of this intervention in its first phase, preschoolers.
Cluster-randomized controlled trial in public schools in the city of Madrid, Spain. A total 24 schools, including 2062 children (3-5 years), 1949 families, and 125 teachers participated in the study. Schools were assigned to their usual school curriculum or to engage in an additional multi-component intervention (Program SI!). The primary outcome of this trial is 1-school year changes from baseline in scores for children's knowledge, attitudes and habits (KAH). Secondary outcomes are 1-school year changes from baseline in scores for knowledge, attitudes, and habits among parents, teachers, and the school environment.
After 1-school year, our results indicate that the Program SI! intervention increases children's KAH scores, both overall (3.45, 95% CI, 1.84-5.05) and component-specific (Diet: 0.93, 95% CI, 0.12-1.75; Physical activity: 1.93, 95% CI, 1.17-2.69; Human body: 0.65, 95% CI, 0.07-1.24) score.
The Program SI! is demonstrated as an effective and feasible strategy for increasing knowledge and improving lifestyle attitudes and habits among very young children.

不健康的生活方式是导致心血管危险因素形成的原因，而心血管危险因素在儿童和青少年中的发病率正在不断上升。SI! 项目是一项长期的、多目标的行为干预措施，旨在通过学校环境促进儿童养成健康的生活习惯。本研究的目的是评估该干预措施在其第一阶段（学龄前儿童）的效果。
这是一项在西班牙马德里市公立学校进行的整群随机对照试验。共有 24 所学校（包括 2062 名儿童[3-5 岁]、1949 个家庭和 125 名教师）参与了这项研究。学校被随机分为常规课程组或额外的多组分干预组（SI! 项目）。该试验的主要结局是儿童知识、态度和习惯（KAH）评分在 1 学年内相对于基线的变化。次要结局是家长、教师和学校环境的知识、态度和习惯评分在 1 学年内相对于基线的变化。
经过 1 学年，我们的结果表明，SI! 项目干预增加了儿童的 KAH 评分，整体评分提高了 3.45（95%可信区间，1.84-5.05），且各组成部分的评分也有所提高，包括饮食（0.93，95%可信区间，0.12-1.75）、身体活动（1.93，95%可信区间，1.17-2.69）和人体知识（0.65，95%可信区间，0.07-1.24）。
SI! 项目被证明是一种有效且可行的策略，可以提高幼儿的知识水平，并改善其生活方式的态度和习惯。
