To evaluate a conceptual model linking parent physical activity (PA) orientations, parental support for PA, and PA behavior in preschool children.
Participants were 156 parent-child dyads from 13 child care centers in Queensland, Australia. Parents completed a questionnaire measuring parental PA, parental enjoyment of PA, perceived importance of PA, parental support for PA, parents' perceptions of competence, and child PA at home. MVPA while attending child care was measured via accelerometry. Data were collected between May and August of 2003. The relationships between the study variables and child PA were tested using observed variable path analysis.
Parental PA and parents' perceptions of competence were positively associated with parental support for PA (beta=0.23 and 0.18, respectively, p<0.05). Parental support, in turn, was positively associated with child PA at home (beta=0.16, p<0.05), but not at child care (beta=0.01, p=0.94). Parents' perceptions of competence was positively associated with both home-based and child care PA (beta=0.20 and 0.28, respectively, p<0.05).
Family-based interventions targeting preschoolers should include strategies to increase parental support for PA. Parents who perceive their child to have low physical competence should be encouraged to provide adequate support for PA.
评估一个概念模型，该模型将父母的身体活动（PA）取向、父母对 PA 的支持与学龄前儿童的 PA 行为联系起来。
参与者为来自澳大利亚昆士兰州 13 家儿童保育中心的 156 对父母-子女对。父母完成了一份问卷，该问卷测量了父母的 PA、父母对 PA 的享受程度、对 PA 的重要性的感知、对 PA 的支持、父母对孩子能力的感知以及孩子在家中的 PA。通过加速度计测量在儿童保育中心参加的中高强度体力活动（MVPA）。数据于 2003 年 5 月至 8 月期间收集。使用观察变量路径分析测试研究变量与儿童 PA 之间的关系。
父母的 PA 和父母对孩子能力的感知与父母对 PA 的支持呈正相关（β=0.23 和 0.18，分别，p<0.05）。反过来，父母的支持与孩子在家中的 PA 呈正相关（β=0.16，p<0.05），但与儿童保育中的 PA 无关（β=0.01，p=0.94）。父母对孩子能力的感知与家庭和儿童保育中的 PA 均呈正相关（β=0.20 和 0.28，分别，p<0.05）。
针对学龄前儿童的基于家庭的干预措施应包括增加父母对 PA 的支持的策略。那些认为自己孩子身体能力较低的父母应该被鼓励为 PA 提供足够的支持。
