This study compared accelerometer-measured physical activity (PA) patterns in adolescents living in diverse urban and rural areas of Otago, New Zealand.
Participants (n=377; age: 14.9±1.4 years; 66.8% female; 23 schools) completed an online school travel survey, anthropometry and seven-day PA accelerometer assessment. Participants resided in large (n=237), medium (n=45) and small (n=44) urban areas or rural settings (n=51).
Overall, participants participated in 54.4±21.0 minutes of moderate-to-vigorous physical activity (MVPA) daily and 35.0% met PA guidelines (school day vs weekend day: 40.8% vs 26.0%; p<0.001) with no difference across geographical settings. A greater proportion of males (43.2% vs 31.9%; p=0.016), school sport participants (70.1% vs 54.0%; p=0.005) and active-transport-to-school users (40.2% vs 26.1%) met PA guidelines compared to their counterparts. Compared to rural adolescents, those from large urban areas accumulated more MVPA during the school commute time (before school: 8.3±6.7 vs 5.3±3.8 minutes, p<0.001; after school: 10.1±6.0 vs 7.7±4.3 min, p=0.003), but overall spent more time sedentary (584.9±84.7 vs 527.8±88.2 minutes/day; p<0.001).
PA in Otago adolescents is low, with significant differences by gender, sport participation, mode of travel to school and geographical setting. Increased PA should be encouraged in both urban and rural adolescents.
本研究比较了生活在新西兰奥塔哥不同城市和农村地区的青少年的加速度计测量的体力活动（PA）模式。
参与者（n=377；年龄：14.9±1.4 岁；66.8%为女性；23 所学校）完成了在线学校旅行调查、人体测量和 7 天 PA 加速度计评估。参与者居住在大城市（n=237）、中城市（n=45）和小城市（n=44）或农村地区（n=51）。
总体而言，参与者每天进行 54.4±21.0 分钟的中等至剧烈体力活动（MVPA），35.0%符合 PA 指南（上学日与周末日：40.8%与 26.0%；p<0.001），不同地理位置之间没有差异。与女性（31.9%）相比，男性（43.2%）、参加学校运动的参与者（70.1%）和使用主动交通上学的参与者（40.2%）更符合 PA 指南。与农村青少年相比，来自大城市的青少年在上学通勤时间内积累了更多的 MVPA（上学前：8.3±6.7 与 5.3±3.8 分钟，p<0.001；放学后：10.1±6.0 与 7.7±4.3 分钟，p=0.003），但总体而言，久坐时间更长（584.9±84.7 与 527.8±88.2 分钟/天；p<0.001）。
奥塔哥青少年的 PA 水平较低，存在显著的性别差异、运动参与度差异、上学交通方式差异和地理位置差异。应鼓励城市和农村青少年增加 PA。
