Heart transplantation is the treatment of choice for children with end-stage heart disease. Coronary artery vasculopathy is, however, a significant morbidity and leading cause of late graft loss, and hyperlipidemia a risk factor for its development. Improving diet in this population could have important benefits for patients. We wanted to understand what influences decisions about food intake in this patient group. Dietary intentions and behavior were examined using a questionnaire based on the Theory of Planned Behavior (TPB) with 67 children who had undergone heart transplantation at least 12 months previously. The TPB model was significant for both healthy and unhealthy dietary behaviors, explaining 55% and 38% of the variance, respectively. Ten percent of children reported not eating any fruit and/or vegetables in the previous week and only 29% reported eating fruit and/or vegetables every day. The Theory of Planned Behavior provides a framework for explaining some specific dietary behaviors related to individual food groups in children who have undergone heart transplantation. These preliminary data support using this approach to inform the development of interventions to improve fruit and vegetable consumption but the approach may be less useful for explaining and developing interventions to reduce the consumption of unhealthy foods.

用计划行为理论探索小儿心脏移植受者的饮食行为

心脏移植是终末期心脏病患儿的首选治疗方法。然而，冠状动脉血管病是严重的发病率和后期移植物丢失的主要原因，而高脂血症则是其发展的危险因素。改善这一人群的饮食可能对患者有重要的好处。我们想了解是什么因素影响了该患者组的食物摄入决定。使用基于计划行为理论（TPB）的问卷调查了饮食意向和行为，调查对象为67位至少在12个月前接受心脏移植的儿童。TPB模型对于健康和不健康的饮食行为均具有重要意义，分别解释了55％和38％的差异。有10％的儿童报告说前一周没有吃任何水果和/或蔬菜，只有29％的孩子每天报告有吃水果和/或蔬菜。计划行为理论提供了一个框架，用于解释与接受心脏移植的儿童中的各个食物组有关的某些特定饮食行为。这些初步数据支持使用这种方法来指导改善水果和蔬菜消费的干预措施的制定，但是该方法对于解释和制定减少不健康食品消费的干预措施可能没有多大用处。
