In children, being sufficiently physically active, having low levels of screen-time and having a healthy diet are largely influenced by parenting practices. Children of parents applying positive parenting practices are at lower risk for overweight and obesity. Therefore, we investigated the effect of a health promoting online video intervention for parents ('Movie Models') on children's physical activity (PA), screen-time and healthy diet, and on specific parenting practices and parental self-efficacy related to these parenting practices. The online videos are delivered to parents of primary schoolchildren, and were based on real-life scenarios.
A two-armed, quasi experimental design was used. Parents of primary schoolchildren were recruited between November and December 2013 by spreading an appeal in social media, and by contacting primary schools. Participating parents were predominantly of high socio-economic status (SES) (83.1%), and only 6.8% of children were overweight/obese. Intervention group participants were invited to watch online videos for 4 weeks. Specific parenting practices, parental self-efficacy, PA, screen-time and healthy diet of the child were assessed at baseline (T0), at one (T1) and at four (T2) months post baseline. Repeated Measures (Multivariate) ANOVAs were used to examine intervention effects. The potential moderating effect of age and gender of the child and parental SES was also examined.
Between T0 and T2, no significant intervention effects were found on children's PA, screen-time or healthy diet. Most significant intervention effects were found for more complex parenting practices (e.g., an increase in motivating the child to eat fruit). Subgroup analyses showed that the intervention had more effect on the actual parenting practices related to PA, screen-time and healthy diet in parents of older children (10-12 years old), whereas intervention effects on parental self-efficacy related to those behaviors were stronger in parents of younger children (6-9 years old).
'Movie Models' was effective in increasing some important parenting practices and parental self-efficacy related to PA, screen-time and healthy diet in children. Therefore, the current study is an important first step in promoting effective parenting-related factors, and possibly increasing children's healthy diet and PA, and decreasing screen-time.

在儿童中，充足的身体活动、较少的屏幕使用时间以及健康的饮食在很大程度上受养育方式的影响。采用积极养育方式的父母的孩子超重和肥胖的风险较低。因此，我们调查了一项针对父母的促进健康的在线视频干预措施（“榜样影片”）对儿童身体活动（PA）、屏幕使用时间和健康饮食的影响，以及对与这些养育方式相关的特定养育方式和父母自我效能的影响。这些在线视频面向小学生的父母，并且基于现实生活场景。
采用双臂准实验设计。2013年11月至12月期间，通过在社交媒体上发布呼吁以及联系小学招募小学生的父母。参与的父母主要具有较高的社会经济地位（SES）（83.1%），只有6.8%的儿童超重/肥胖。干预组参与者被邀请观看在线视频，为期4周。在基线（T0）、基线后1个月（T1）和4个月（T2）时评估儿童的特定养育方式、父母自我效能、PA、屏幕使用时间和健康饮食。采用重复测量（多变量）方差分析来检验干预效果。还检验了儿童年龄和性别以及父母SES的潜在调节作用。
在T0和T2之间，未发现干预对儿童的PA、屏幕使用时间或健康饮食有显著影响。在更复杂的养育方式（例如，增加激励孩子吃水果的行为）方面发现了最显著的干预效果。亚组分析表明，干预对年龄较大儿童（10 - 12岁）的父母中与PA、屏幕使用时间和健康饮食相关的实际养育方式影响更大，而对年龄较小儿童（6 - 9岁）的父母中与这些行为相关的父母自我效能的干预效果更强。
“榜样影片”在增加一些与儿童PA、屏幕使用时间和健康饮食相关的重要养育方式和父母自我效能方面是有效的。因此，本研究是促进有效养育相关因素、可能增加儿童健康饮食和PA以及减少屏幕使用时间的重要第一步。
