探讨八年级女生上学前后的“步行旅行”（TBW）。参与者参加了来自亚利桑那州，马里兰州，明尼苏达州，新奥尔良，加州和南卡罗来纳州参加青春期女孩活动试验（TAAG）的36所中学。横断面样本包括3,076名八年级女生，纵向样本包括1,017名参加六年级和八年级的女生。通过3天身体活动回忆（3DPAR）确定上学前或放学后的步行旅行状态。主要结果是身体质量指数（BMI）和身体活动，通过加速度计测量，估计总身体活动（轻度，中度，剧烈）和中度至剧烈身体活动（MVPA）。报告TBW的八年级女孩有4分钟以上（95%置信区间[CI]，2.1-6.1。与不步行的人相比，在上学前和放学后的MVPA，平均工作日多2分钟的MVPA（95%CI，1.1-3.1）。在纵向样本中，在六年级和八年级上学前后报告TBW的女孩（持续步行者）在平均工作日积累的MVPA分钟数比六年级（27分钟±2.2 vs. 25分钟±1.9; p= 0.03）和八年级（28分钟±2.6 vs. 25分钟±2.3; p= 0.003）的不一致步行者多。不同步行状态的BMI没有差异。在上学前后报告TBW的青少年女孩比非步行者积累了更多的MVPA分钟。努力防止中学女生步行上学的减少可能有助于她们的整体身体活动。
To examine “travel by walking” (TBW) before and after school among eighth grade girls. Participants attended 36 middle schools from Arizona, Maryland, Minnesota, New Orleans, California and South Carolina participating in the Trial of Activity for Adolescent Girls (TAAG). The cross-sectional sample consisted of 3,076 eighth grade girls, and the longitudinal sample included 1,017 girls who participated in both 6th and 8th grades. Travel by walking before or after school status was determined from the 3-Day Physical Activity Recall (3DPAR). The main outcomes were body mass index (BMI) and physical activity, which was measured by accelerometry, estimated for total physical activity (light, moderate, vigorous) and moderate to vigorous physical activity (MVPA). Eighth grade girls who reported TBW had 4 more minutes (95% confidence interval ([CI], 2.1–6.1.) of MVPA before and after school than non-walkers, and 2 more minutes of MVPA (95% CI, 1.1–3.1) on an average weekday. In the longitudinal sample, girls who reported TBW before and after school in both 6th and 8th grades (consistent walkers) accumulated more minutes of MVPA for an average weekday than inconsistent walkers in both sixth (27 min.±2.2 vs. 25 min.±1.9; p=.03) and eighth grades (28 min.±2.6 vs. 25 min.±2.3; p=.003). There were no differences in BMI by walking status. Adolescent girls who reported TBW before and after school accumulated more minutes of MVPA than non-walkers. Efforts to prevent the decline in walking to school in middle school girls could contribute to their overall physical activity.
