The ‘Planning Health in School’ programme (PHS-pro) is a behavioural change intervention to assess and improve the eating habits of children, particularly the intake of fruit and vegetables, and to guide them towards healthy choices. The programme and its educational components are based on the Transtheoretical Model of stages of change to integrate nutritional literacy and build up problem-solving and decision-making skills. Children (n = 240, ages 10–12) of one large suburban school in Porto’s metropolitan area (Portugal) were evaluated throughout PHS-pro implementation during one school year in a repeated time–series design. Children’s outcome evaluations were conducted through seven 3-day food records for nine eating behaviour, documented after each learning module and through participatory activities which analysed attitudes, preferences and expectations. Changes were observed in children’s eating behaviour, supported by changes in motivation as perceived in their attitudes and expectations. Significant changes were found in a higher consumption of vegetable soup (p = 0.003), milk products (p = 0.024), and fruit (p = 0.008), while the consumption of high-energy dense food (p = 0.048) and soft drinks (p = 0.042) significantly decreased. No positive effects on fried food, water, vegetables and bread consumption were found. The PHS-pro intervention proved to be effective in developing healthy eating behaviour in young people.

孩子学习，孩子做！行为改变计划“学校健康计划”的结果

“学校健康计划”计划 (PHS-pro) 是一项行为改变干预措施，旨在评估和改善儿童的饮食习惯，尤其是水果和蔬菜的摄入量，并指导他们做出健康选择。该计划及其教育组成部分基于变革阶段的跨理论模型，以整合营养素养并建立解决问题和决策的技能。儿童 ( n= 240，年龄 10-12 岁）的一所位于波尔图大都市区（葡萄牙）的大型郊区学校，在一个学年的整个 PHS-pro 实施过程中，以重复的时间序列设计进行评估。儿童的结果评估是通过 9 种饮食行为的 7 份 3 天食物记录进行的，记录在每个学习模块之后，并通过分析态度、偏好和期望的参与性活动进行。观察到儿童的饮食行为发生了变化，这得到了他们的态度和期望中所感知的动机变化的支持。蔬菜汤 ( p = 0.003)、奶制品 ( p = 0.024) 和水果 ( p = 0.008) 的摄入量较高，而高能量密度食物 (p = 0.048) 和软饮料 ( p = 0.042) 显着下降。未发现对油炸食品、水、蔬菜和面包消费有积极影响。PHS-pro 干预被证明对培养年轻人的健康饮食行为是有效的。
