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一个非面对面的项目对孩子和他们的父母增加身体活动的有效性。该程序由生活方式评估和代币经济制定体育活动计划组成。招募了46个家庭（65名家长和56名儿童），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育锻炼计划，并监测每日步数。对照组不进行干预。两组的所有参与者都佩戴了一个计步器（Yamax SW-200），作为日常身体活动的客观衡量标准。父母平均年龄为38.0±6.2岁，儿童平均年龄为5.9±1.3岁。问卷完成率为76.1%（35个家庭）。在不包括行动和维持阶段的父母中，干预组的每日步数显著高于对照组。然而，两组儿童的每日步数没有显著差异。家长对节目内容的总满意度较高（平均=7.9±1.0分，最高10分）。总之，这种为期6周的邮件干预对那些在基线时没有锻炼的父母的身体活动变化是有效的。需要更多的研究来调查影响儿童体育活动水平的因素。

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.
