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

本研究的目的是验证一个非面对面的计划，为孩子和他们的父母，以增加身体活动的有效性。该计划包括生活方式评估和使用代币经济制定身体活动计划。46个家庭（65名家长和56名儿童）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）。干预组与他们的家人一起制定身体活动计划，并监测每天的步数。对照组不接受任何干预。作为日常体力活动的客观测量，两组中的所有参与者都佩戴了步数计（Yamax SW-200）。父母的平均年龄为38.0±6.2岁，子女的平均年龄为5.9±1.3岁。35个家庭的遵医率为76.1%，在排除行动和维持阶段的家长中，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。家长对该项目内容的总体满意度得分相对较高（平均得分=7.9±1.0，最高10分）。总之，这6周的邮件干预对基线时不锻炼的家长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身体活动水平的因素。

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.
