The purpose of this study was to test a conceptual model linking parental support and parental physical activity (PA), with children's perception of parental support and children's PA. Baseline data were drawn from the Grade 5 ACT-i-Pass community-based PA intervention conducted in London, Ontario between May and October 2014. Parent and child PA were measured using the International Physical Activity Questionnaire and Physical Activity Questionnaire for Children, respectively. Questions pertaining to parental support and children's perception of that parental support were obtained via questionnaires. We employed structural equation modeling techniques to test the conceptual model. In total, 467 boys and 469 girls were included in the study. The model provided an acceptable model fit. Child's perception of parental support for PA had a positive effect on boys' (b=0.319) and girls' (b=0.326) PA. Parental PA was not significantly related to child's perception of parental support for PA. However, parent reported support for PA had a significant, positive effect on child's perception of parental support for boys (b=0.352) and girls (b=0.584). In terms of the indirect effects, the effect of parental PA on child's PA was not statistically significant; however, as expected, parental support for PA had a statistically significant indirect effect on child PA level in both groups. The findings of this study demonstrate the importance of children's perceptions of parental support in relation to their PA behaviours. Developing a better understanding of factors related to children's PA and identifying determinants and mediators of activity behaviours will help inform PA interventions.
本研究旨在检验一个概念模型，该模型将父母支持与父母身体活动（PA）与儿童对父母支持的感知和儿童的 PA 联系起来。基线数据来自于 2014 年 5 月至 10 月在安大略省伦敦市进行的五年级 ACT-i-Pass 基于社区的 PA 干预。父母和孩子的 PA 分别使用国际体力活动问卷和儿童体力活动问卷进行测量。关于父母支持和孩子对父母支持的感知的问题是通过问卷获得的。我们采用结构方程模型技术来检验概念模型。共有 467 名男孩和 469 名女孩参与了这项研究。该模型提供了可接受的模型拟合度。儿童对父母 PA 的支持感知对男孩（b=0.319）和女孩（b=0.326）的 PA 有积极影响。父母的 PA 与孩子对父母 PA 的支持感知没有显著关系。然而，父母报告的对 PA 的支持对男孩（b=0.352）和女孩（b=0.584）的儿童对父母支持的感知有显著的积极影响。就间接影响而言，父母 PA 对儿童 PA 的影响不具有统计学意义；然而，正如预期的那样，父母对 PA 的支持对两个群体中儿童 PA 水平具有统计学上显著的间接影响。本研究的结果表明，儿童对父母支持的感知在其 PA 行为中起着重要作用。更好地了解与儿童 PA 相关的因素，并确定活动行为的决定因素和中介因素，将有助于指导 PA 干预。
