游戏街是在学校放假期间为孩子们在特定时间段预留的安全玩耍的街道。据推测，儿童之家附近的游乐街可以增加他们中等强度到剧烈的体力活动(MVPA)，减少他们坐着的时间。因此，本研究的目的是探讨游戏街道对儿童MVPA和久坐时间的影响，采用非等价对照组前测-后测设计来确定游戏街道对儿童MVPA和久坐时间的影响。数据是2013年7月至8月在根特收集的。研究样本包括126名儿童(54名来自玩耍街道，72名来自对照街道)。孩子们连续8天佩戴加速度计，他们的父母在测量期前后填写一份问卷。在干预期间，街道被封闭并预留给儿童玩耍。在MLwiN中进行四水平(社区-家庭-子女-测量时间(未干预或干预中))线性回归模型以确定干预效果，正向干预效果分别为：久坐时间(Beta=-0.76+/-0.39；X-2=3.9；p=0.05)和MVPA(Beta=0.82+/-0.43；X-2=3.6；p=0.06)。在14：00到19：00之间，生活在游戏街的儿童的MVPA从正常情况下的27分钟增加到游戏街干预期间的36分钟，而对照组儿童的MVPA从27分钟减少到24分钟。生活在游戏街的儿童的久坐时间从正常情况下的146分钟减少到游戏街干预期间的138分钟，而对照组儿童的久坐时间从156分钟增加到165分钟。对MVPA(beta=-0.62+/-0.25；X-2=6.3；p=0.01)和久坐时间(beta=0.85+/-0.0.33；X-2=6.6；p=0.01)的干预效果仍然显著，表明儿童在其他时间没有补偿他们增加的MVPA和减少的久坐时间。通过游戏街干预在城市儿童家附近创造一个安全的游戏空间，有效地增加儿童的MVPA和减少他们的久坐时间。
A Play Street is a street that is reserved for children's safe play for a specific period during school vacations. It was hypothesized that a Play Street near children's home can increase their moderate- to vigorous-intensity physical activity (MVPA) and decrease their sedentary time. Therefore, the aim of this study was to investigate the effect of Play Streets on children's MVPA and sedentary time.A nonequivalent control group pretest-posttest design was used to determine the effects of Play Streets on children's MVPA and sedentary time. Data were collected in Ghent during July and August 2013. The study sample consisted of 126 children (54 from Play streets, 72 from control streets). Children wore an accelerometer for 8 consecutive days and their parents fill out a questionnaire before and after the measurement period. During the intervention, streets were enclosed and reserved for children's play. Four-level (neighborhood - household - child - time of measurement (no intervention or during intervention)) linear regression models were conducted in MLwiN to determine intervention effects.Positive intervention effects were found for sedentary time (beta = -0.76 +/- 0.39; X-2 = 3.9; p = 0.05) and MVPA (beta = 0.82 +/- 0.43; X-2 = 3.6; p = 0.06). Between 14h00 and 19h00, MVPA from children living in Play Streets increased from 27 minutes during normal conditions to 36 minutes during the Play Street intervention, whereas control children's MVPA decreased from 27 to 24 minutes. Sedentary time from children living in the Play Street decreased from 146 minutes during normal conditions to 138 minutes during the Play Street intervention, whereas control children's sedentary time increased from 156 minutes to 165 minutes. The intervention effects on MVPA (beta = -0.62 +/- 0.25; X-2 = 6.3; p = 0.01) and sedentary time (beta = 0.85 +/- 0.0.33; X-2 = 6.6; p = 0.01) remained significant when the effects were investigated during the entire day, indicating that children did not compensate for their increased MVPA and decreased sedentary time, during the rest of the day.Creating a safe play space near urban children's home by the Play Street intervention is effective in increasing children's MVPA and decreasing their sedentary time.
