The development and evaluation of a non face-to-face program for Kids and Parents to increase physical activity

这项研究的目的是验证为孩子和他们的父母提供的非面对面计划增加体力活动的有效性。该项目包括生活方式评估和制定象征性经济的体育锻炼计划。46个家庭(65个家长和56个孩子)被随机分为两组：6周邮件干预组(23个家庭)和对照组(23个家庭)。干预组与家人制定体力活动计划，监测日常步数。对照组未接受任何干预。作为每日体力活动的客观测量，两组的所有参与者都佩戴了步数计数器(Yamax SW-200)。父母平均年龄38.0±6.2岁，儿童平均年龄5.9±1.3岁。完成后问卷调查的35个家庭的遵从率为76.1%，在不包括行动和赡养阶段的家长中，干预组的日常生活步数显著高于对照组。然而，两组儿童的日常步数没有显著差异。家长对该计划内容的总体满意度得分较高(平均得分=7.9±1.0，最高10分)。结论：6周邮寄干预对基线没有锻炼的父母的体力活动改变是有效的。需要更多的研究来调查影响儿童体力活动水平的因素。

The purpose of this study was to verify the effectiveness of a non face-to-face program for kids and their parents to increase physical activity. This program consists of life style assessment and making physical activity plan with token economy. 46 families (65 parents and 56 children) were recruited and randomly assigned to two groups ; 6 week mail intervention group (23 families) and control group (23 families). Intervention group created physical activity plan with their family and monitored daily steps. The control group received no intervention. As an objective measure of daily physical activity, a step counter (Yamax SW-200) was worn by all participants in both groups. The mean parent's age was 38.0±6.2 and children's age was 5.9±1.3. The compliance rate, defined as the completion of the post-questionnaire was 76.1% (35 families).In parents excluding action & maintenance stages, daily steps in the intervention group was significantly higher than that of in the control group. However, there were no significant differences in children's daily steps in both groups. Total satisfaction score to this program contents by parents was relatively high (mean score=7.9±1.0, Max.10 point).In conclusion, this 6 weeks mail intervention was effective for physical activity changes in parents who were not exercising at baseline. More research is needed to investigate factors affecting physical activity levels in children.
