目标：尽管自2011-2012学年以来，佐治亚州公立学校已经收集了FitnessGram健身有关有氧能力和身体质量指数(BMI)的数据，但尚未对数据进行分析。我们研究的主要目标是使用这些数据来评估2011至2014年间佐治亚州学龄儿童健康状况的变化。第二个目标是确定学生的健康是否因学校规模和社会经济特征而不同。方法：Fitnessgram根据有氧能力和BMI将学生的健康状况归入健康健身区(HFZ)或不属于HFZ区。我们使用了连续3个学年(即2011-2012年至2013-2014学年)的数据，这些数据来自于对1600所学校的学生进行的FitnessGram测试。我们计算了学生达到HFZ有氧能力和BMI的百分比。结果：无论是小学男生(Beta=1.31%，标准差[SE]=0.23%，P<；.001)和女生(Beta=1.53%，SE=0.26%，P<；.001)，HFZ在有氧能力方面的成绩都有显著的年度增长。小学男生(Beta=3.11%，SE=0.32%，P<；.001)和女生(Beta=3.09%，SE=0.32%，P<；.001)的BMI HFZ成就比例也有显著增加，尽管这些增加主要发生在2011-2012年和2012-2013年之间。中学生的身体质量指数HFZ成就比例参差不齐，我们没有观察到高中生的增加。更大的学校规模和更高的学校社会经济地位与更好的有氧能力和BMI健康状况相关。结论：这样的监测结果可能有助于为制定州和地方校本健身促进和公共卫生计划并跟踪这些计划的结果提供信息。
Objectives: Although FitnessGram fitness data on aerobic capacity and body mass index (BMI) have been collected in public schools in Georgia since the 2011-2012 school year, the data have not been analyzed. The primary objective of our study was to use these data to assess changes in fitness among school-aged children in Georgia between 2011 and 2014. A secondary objective was to determine if student fitness differed by school size and socioeconomic characteristics.Methods: FitnessGram classifies fitness into the Healthy Fitness Zone (HFZ) or not within the HFZ for aerobic capacity and BMI. We used data for 3 successive school years (ie, 2011-2012 to 2013-2014) obtained from FitnessGram testing of students in >1600 schools. We calculated the percentage of students who achieved the HFZ for aerobic capacity and BMI. We used growth curve models to estimate the annual changes in these proportions, and we determined the effect of school size and socioeconomic status on these changes.Results: Both elementary school boys (beta = 1.31%, standard error [SE] = 0.23%, P < .001) and girls (beta = 1.53%, SE = 0.26%, P < .001) had significant annual increases in achievement of HFZ for aerobic capacity. Elementary school boys (beta = 3.11%, SE = 0.32%, P < .001) and girls (beta = 3.09%, SE = 0.32%, P < .001) also had significant increases in their BMI HFZ achievement proportions, although these increases occurred primarily between 2011-2012 and 2012-2013. Body mass index HFZ achievement proportions were mixed for middle school students, and we did not observe increases for high school students. Larger school size and higher school socioeconomic status were associated with better aerobic capacity and BMI fitness profiles.Conclusions: Surveillance results such as these may help inform the process of designing state and local school-based fitness promotion and public health programs and tracking the results of those programs.
