BACKGROUND
Children's physical activity (PA) is inversely associated with children's weight status. Parents may be an important influence on children's PA by restricting sedentary time or supporting PA. The aim of this study was to investigate the association of PA and screen-media-related [television (TV) and videogame] parenting practices with children's PA.
METHODS
Secondary analyses of baseline data were performed from an intervention with 9- to 12-year-olds who received active or inactive videogames (n=83) to promote PA. Children's PA was assessed with 1 week of accelerometry at baseline. Parents reported their PA, TV, and videogame parenting practices and child's bedroom screen-media availability. Associations were investigated using Spearman's partial correlations and linear regressions.
RESULTS
Although several TV and videogame parenting practices were significantly intercorrelated, only a few significant correlations existed between screen-media and PA parenting practices. In linear regression models, restrictive TV parenting practices were associated with greater child sedentary time (p=0.03) and less moderate-to-vigorous PA (MVPA; p=0.01). PA logistic support parenting practices were associated with greater child MVPA (p=0.03). Increased availability of screen-media equipment in the child's bedroom was associated with more sedentary time (p=0.02) and less light PA (p=0.01) and MVPA (p=0.05) in all three models.
CONCLUSION
In this cross-sectional sample, restrictive screen-media and supportive PA parenting practices had opposite associations with children's PA. Longitudinal and experimental child PA studies should assess PA and screen-media parenting separately to understand how parents influence their child's PA behaviors and whether the child's baseline PA or screen media behaviors affect the parent's use of parenting practices. Recommendations to remove screens from children's bedrooms may also affect their PA.
背景
儿童的身体活动（PA）与儿童的体重状况呈负相关。父母可能通过限制久坐时间或支持 PA 对儿童的 PA 产生重要影响。本研究旨在调查 PA 与与屏幕媒体相关的[电视（TV）和视频游戏]育儿实践与儿童 PA 的关系。
方法
对接受主动或被动视频游戏（n=83）以促进 PA 的 9 至 12 岁儿童进行干预的基线数据进行二次分析。在基线时使用 1 周的加速计评估儿童的 PA。父母报告他们的 PA、电视和视频游戏育儿实践以及孩子卧室屏幕媒体的可用性。使用 Spearman 的偏相关和线性回归来研究相关性。
结果
尽管几种电视和视频游戏育儿实践之间存在显著的相关性，但屏幕媒体和 PA 育儿实践之间只有少数存在显著相关性。在线性回归模型中，限制电视育儿实践与儿童久坐时间增加（p=0.03）和中高强度 PA（MVPA；p=0.01）减少相关。PA 逻辑支持育儿实践与儿童 MVPA 增加相关（p=0.03）。儿童卧室中屏幕媒体设备的可用性增加与更多的久坐时间（p=0.02）、较少的轻度 PA（p=0.01）和 MVPA（p=0.05）相关。
结论
在这个横断面样本中，限制屏幕媒体和支持 PA 的育儿实践与儿童的 PA 呈相反关系。纵向和实验性儿童 PA 研究应分别评估 PA 和屏幕媒体育儿实践，以了解父母如何影响孩子的 PA 行为，以及孩子的基线 PA 或屏幕媒体行为是否影响父母使用育儿实践。从孩子的卧室中移除屏幕的建议也可能影响他们的 PA。
