家庭环境对儿童的水果和蔬菜(FV)消费有重要影响，但儿童也可能反过来影响他们的家庭FV环境，例如通过要求FV。乡绅的任务II严肃的游戏干预旨在增加询问行为，以改善家庭FV的可用性和儿童的FV摄入量。这项研究的目的是评估：1)基线时的询问行为是否预测基线时的家庭FV可用性(T0)(RQ1)；2)询问行为和家庭FV可用性是否受到干预的影响(RQ2)；3)询问行为的增加是否预测家庭FV可用性的增加(RQ3)；以及4)询问行为的增加和家庭FV可用性的增加是否中介了儿童FV摄入量的增加(RQ4)？这是一项使用随机对照试验的研究的二次分析，有4组(每组n = 100个孩子-父母二元组)。由于各组在与我们的分析相关的成分上没有不同，所以所有组都在一起进行了分析。所有儿童和家长(n， = ，400对)都接受了自我调节，严肃的游戏干预和家长材料。干预持续了三个月。分别在基线、干预后即刻和3个月随访时进行测量。询问行为和家庭FV的可用性通过问卷调查来衡量；儿童FV的摄入量通过24小时饮食回忆来衡量。研究采用了方差分析方法(研究问题1)、线性混合效应模型(研究问题2)和结构方程模型(研究问题3和4)。基线儿童询问行为预测了基线家庭FV可用性。干预增加了儿童的提问行为和家庭FV的可用性。然而，儿童询问行为的增加并不预示家庭FV可用性的增加。儿童询问行为的增加和家庭FV的可获得性也不能调节儿童FV摄入量的增加。儿童通过询问行为来影响他们的家庭FV环境，这种行为可以通过严肃的游戏干预来增强。然而，询问行为的增加不足以影响家庭FV的可用性或摄入量。其他因素，如儿童偏好、样本特征、干预持续时间和父母的直接参与，可能会在未来的研究中发挥作用并需要进行检查。临床试验.gov NCT01004094。注册日期2009年10月28日本文的在线版本(doi：10.1186/s12966-0170506-y)包含补充材料，可供授权用户使用。
Home environment has an important influence on children’s fruit and vegetable (FV) consumption, but children may in turn also impact their home FV environment, e.g. by asking for FV. The Squire’s Quest II serious game intervention aimed to increase asking behaviors to improve home FV availability and children’s FV intake. This study’s aims were to assess: 1) did asking behaviors at baseline predict home FV availability at baseline (T0) (RQ1); 2) were asking behaviors and home FV availability influenced by the intervention (RQ2); 3) did increases in asking behaviors predict increased home FV availability (RQ3); and 4) did increases in asking behaviors and increases in home FV availability mediate increases in FV intake among children (RQ4)? This is a secondary analysis of a study using a randomized controlled trial, with 4 groups (each n = 100 child–parent dyads). All groups were analyzed together for this paper since groups did not vary on components relevant to our analysis. All children and parents (n = 400 dyads) received a self-regulation serious game intervention and parent material. The intervention ran for three months. Measurements were taken at baseline, immediately after intervention and at 3-month follow-up. Asking behavior and home FV availability were measured using questionnaires; child FV intake was measured using 24-h dietary recalls. ANCOVA methods (research question 1), linear mixed-effect models (research question 2), and Structural Equation Modeling (research questions 3 and 4) were used. Baseline child asking behaviors predicted baseline home FV availability. The intervention increased child asking behaviors and home FV availability. Increases in child asking behaviors, however, did not predict increased home FV availability. Increased child asking behaviors and home FV availability also did not mediate the increases in child FV intake. Children influence their home FV environment through their asking behaviors, which can be enhanced via a serious game intervention. The obtained increases in asking behavior were, however, insufficient to affect home FV availability or intake. Other factors, such as child preferences, sample characteristics, intervention duration and parental direct involvement may play a role and warrant examination in future research.
