A previous version of Scouting Nutrition and Activity Program (SNAP) resulted in greater physical activity (PA) during troop meetings, but no impact on girls' body mass index (BMI) or overall PA. The purpose of this study was to evaluate the effects of a 6-month intervention that coupled the evidence-based program SNAP with a channel of communication to parents using health report cards.
Thirty-two Girl Scouts (mean age = 9.5, SD = 1.4 years) received the SNAP+ intervention. Girls were measured before and after the intervention on body composition, BMI, and 7-day step counts. Troop leaders were trained to implement an interactive obesity-prevention curriculum. Parents received health report cards designed to provide personalized information about their daughters' PA and weight status.
The full sample of participants took more steps per day after the intervention (mean difference = 1741, P= 0.007). Results showed that lower values for body fat percentage (P= 0.620), BMI percentile (P= 0.100) and BMI z-scores (P= 0.055) at intervention end were not statistically significant. In the subsample of girls at risk for overweight and obesity, there were lower values for BMI z-score (P= 0.010), BMI percentile (P= 0.027), and body fat percentage (P= 0.053).
From this preliminary study, the SNAP+ intervention appears to be effective for Scout-based promotion of PA, and for the prevention of overweight and obesity in at-risk Girl Scouts, but further evaluation through a fully powered randomized controlled trial is warranted.
早期版本的童子军营养与活动计划（SNAP）在团队会议期间增加了身体活动（PA），但对女孩的体重指数（BMI）或总体身体活动没有影响。本研究的目的是评估一项为期6个月的干预措施的效果，该措施将循证计划SNAP与通过健康报告卡与家长沟通的渠道相结合。
32名女童子军（平均年龄=9.5岁，标准差=1.4岁）接受了SNAP+干预。在干预前后对女孩的身体成分、BMI和7天步数进行测量。团队领导接受了实施交互式肥胖预防课程的培训。家长收到了旨在提供有关其女儿身体活动和体重状况的个性化信息的健康报告卡。
干预后，参与者的全样本每天走的步数更多（平均差异=1741，P=0.007）。结果显示，干预结束时身体脂肪百分比（P=0.620）、BMI百分位数（P=0.100）和BMI z评分（P=0.055）较低，差异无统计学意义。在超重和肥胖风险女孩的子样本中，BMI z评分（P=0.010）、BMI百分位数（P=0.027）和身体脂肪百分比（P=0.053）较低。
从这项初步研究来看，SNAP+干预似乎对以童子军为基础促进身体活动以及预防有风险的女童子军超重和肥胖有效，但有必要通过一项充分有力的随机对照试验进行进一步评估。
