利用体育活动的客观测量和自我报告测量来确定中学女生体育活动的年变化率。参与者是来自对照学校的六年级和八年级的少女活动试验（TAAG）。随机横断面样本最初从六年级女生中抽取（n=786），两年后从八年级女生中抽取（n=1545）。在6年级和8年级的样本中，有501名女孩。这些女孩佩戴加速度计6天，并完成3天体力活动回忆（3DPAR）。使用3.0-4.6和6.5 met的加速测量和自我报告的身体活动临界值对数据进行汇总。分析采用PROC MIXED中的重复测量方差分析。超过40%的女孩是白人，大约20%是非裔美国人，20%是西班牙裔。使用加速度计数据，横断面样本中体力活动的年减少百分比约为4% （- 1.76 min MVPA/天）。根据体力活动变量的不同，基于自我报告数据的体力活动减少的百分比更高，为6-13%。非裔美国女孩的下降幅度更大，但种族差异在统计上并不显著。根据对六年级和八年级女生横断面样本的比较，客观测量的体育活动以每年4%的速度下降。
To determine the annual rate at which physical activity changes in girls during middle school using both objective and self-report measures of physical activity. Participants were 6th and 8th grade girls from the control schools in the Trial of Activity for Adolescent Girls (TAAG). Random cross-sectional samples initially were drawn from 6th grade girls (n=786) and two years later from 8th grade girls (n=1545). A cohort of 501 girls was in both the 6th and the 8th grade samples. The girls wore an accelerometer for six days and completed the 3-Day Physical Activity Recall (3DPAR). Data were summarized using 3.0–4.6- and 6.5-MET cutpoints for accelerometry and self-reported physical activity. Analyses were performed using repeated measures ANOVA in PROC MIXED. More than 40% of the girls were White, approximately 20% were African-American, and 20% were Hispanic. The annual percent decrease in physical activity in the cross-sectional sample was approximately 4% (−1.76 min MVPA/day), using accelerometer data. The percent decrease in physical activity based on self-report data was higher, 6–13%, depending on the physical activity variable. Declines tended to be larger in African-American girls, but the ethnic differences were not statistically significant. Based on comparisons of cross-sectional samples of 6th and 8th grade girls, objectively-measured physical activity declined at a rate of 4% per year.
