Abstract：
OBJECTIVE: Childhood offers an excellent window of opportunity to start interventions to promote behavioral changes before unhealthy lifestyles become established, leading to cardiovascular diseases. The goal of this pilot educational project for children is the promotion of healthy lifestyles and cardiovascular health.
METHODS: This project was implemented in 4th grade children and included teacher-led classroom activities, a lesson given by a cardiologist and a practical lesson with dietitians. The teacher received a manual containing information on the topics to be discussed in class with the pupils and the children received a book that addresses cardiovascular risk factors and prevention. The components included were diet (D), physical activity (PA) and human body and heart awareness (BH). At the beginning and at the end of the schoolyear, a questionnaire was applied to the children to assess knowledge (K), attitudes (A) and habits (H) on these topics.
RESULTS: A total of 73 children from two schools from an urban district public school in Lisbon, in a low to medium income area, participated in the project. Following the intervention, there was a 9.5% increase in the overall KAH score, mainly driven by the PA component (14.5%) followed by the BH component (12.3%). No improvement was observed for component D. The benefits were also more significant in children from a lower income area, suggesting that socioeconomic status is a determinant in the response obtained.
CONCLUSIONS: An educational project for cardiovascular health can be implemented successfully in children aged 9 years, but longer and larger studies are necessary.

摘要：
目标：童年提供了一个极好的机会窗口，可以在不健康的生活方式建立之前开始干预措施以促进行为改变，导致心血管疾病。这项针对儿童的试点教育项目的目标是促进健康的生活方式和心血管健康。
方法：该项目在四年级儿童中实施，包括教师主导的课堂活动，心脏病学家的教训和营养师的实践教训。老师收到了一本手册，其中包含与学生在课堂上讨论的主题的信息，孩子们收到了一本关于心血管危险因素和预防的书。包括的成分是饮食（D），身体活动（PA）和人体和心脏意识（BH）。在学年开始和结束时，对儿童进行问卷调查以评估知识(K)，对这些主题的态度（A）和习惯（H）。
结果：里斯本一所城市公立学校共有73名儿童，在中低收入地区，参与了该项目。干预之后,KAH总分增加了9.5%,主要由PA成分（14.5％）驱动，其次是BH成分（12.3％）。组件D没有观察到改善。收入较低地区的儿童的益处也更显著。这表明社会经济地位是获得的反应的决定因素。
结论：心血管健康教育项目可以在9岁儿童中成功实施，但更长时间和更大的研究是必要的。
