背景：许多儿童没有达到当前英国体育活动（PA）指南的要求。女孩在整个童年时期都不如男孩活跃，而且与年龄相关的PA下降，尤其是从青春期早期开始，女孩比男孩更明显。舞蹈是英国中学女生最喜欢的PA形式。放学后提供舞蹈课程可以对女孩的PA做出重大贡献。因此，课后舞蹈可能是一种适当的、具有成本效益的活动，通过它可以提高青春期女孩的PA水平。设计：在大布里斯托尔地区的18所中学进行了双组随机对照试验和经济评估。所有参与学校的七年级女生都将参加一个“品尝”舞蹈课程，然后被邀请参加这个项目。每所学校最多可容纳33名女生参加。基线数据收集完成后，学校将被随机分为干预组和对照组。九所干预学校将接受为期20周的课后舞蹈干预，由外部舞蹈教练提供40 x 75分钟的课程。对照学校将不接受舞蹈干预。所有措施将在基线（时间0）、干预期结束（时间1）和干预结束后6个月（时间2）进行评估。我们的主要兴趣是确定干预措施的有效性和成本效益，以影响客观评估的（加速度计）7年级女孩在基线测量（时间2）一年后积累的中度至重度PA （MVPA）的平均工作日分钟数。讨论：本文描述了布里斯托尔女孩舞蹈项目集群随机对照试验和经济评估的方案，该项目试图增加英国中学七年级女孩的MVPA。
Background: Many children do not meet current UK physical activity (PA) guidelines. Girls are less active than boys throughout childhood, and the age-related decline in PA, particularly from early adolescence, is steeper for girls than for boys. Dance is the favourite form of PA among UK secondary school aged girls. Delivering dance sessions after school could make a significant contribution to girls' PA. Therefore, after-school dance sessions may be an appropriate and cost-effective activity through which adolescent girls' PA levels can be increased.Design: Two-arm cluster randomised control trial and economic evaluation conducted in 18 secondary schools across the greater Bristol area. All Year 7 girls in participating schools will receive a 'taster' dance session and subsequently be invited to participate in the project. There is space for up to 33 girls to participate in each school. Schools will be randomly assigned in equal numbers to intervention or control arms after baseline data has been collected. The nine intervention schools will receive a 20 week after-school dance-based intervention, consisting of 40 x 75 minute sessions, delivered by external dance instructors. Control schools will not receive the dance intervention. All measures will be assessed at baseline (time 0), at the end of the intervention period (time 1) and six months after the intervention has ended (time 2). Our primary interest is to determine the effectiveness and cost-effectiveness of the intervention to affect the objectively-assessed (accelerometer) mean weekday minutes of moderate-to-vigorous PA (MVPA) accumulated by Year 7 girls one year after the baseline measurement (time 2).Discussion: This paper describes the protocol for the Bristol Girls Dance Project cluster randomized controlled trial and economic evaluation, which is attempting to increase MVPA among Year 7 girls in UK secondary schools.
