To investigate whether adolescents living in a high-walkable town centre are more physically active than those living in a less-walkable suburb.
This cross-sectional study was conducted in Izegem (Belgium). Data collection took place in spring 2007. One high-walkable urban neighbourhood and one less-walkable suburban neighbourhood were selected, based on objective connectivity and residential density. One hundred twenty adolescents (12-18 years, 60 per neighbourhood) completed the Neighbourhood Environmental Walkability Scale (NEWS), the Neighbourhood Physical Activity Questionnaire (NPAQ), wore a pedometer for 7 days and filled in an activity log.
In contrast with the expectations, adolescents living in the less-walkable suburb reported 220 min/week more cycling for transport than those living in the high-walkable town centre. A trend towards significance was found for mean step counts/day with 1371 more steps/day for suburban adolescents. Travel time to school was 7.4 min less for urban adolescents.
In contrast with previous results in adults, lower walkability and larger distance to school was associated with more physical activity in Belgian adolescents. Therefore, physical environmental interventions designed for adults, focusing on increases in connectivity, residential density and connectivity, might not be effective for Belgian adolescents.
调查居住在高可步行性市中心的青少年是否比居住在低可步行性郊区的青少年更活跃。
这是一项在伊泽格姆（比利时）进行的横断面研究。数据收集于 2007 年春季进行。根据客观的连通性和居住密度，选择了一个高可步行的城市社区和一个低可步行的郊区社区。120 名青少年（12-18 岁，每个社区 60 名）完成了邻里环境步行性量表（NEWS）、邻里体力活动问卷（NPAQ），佩戴计步器 7 天并填写活动日志。
与预期相反，居住在低可步行性郊区的青少年报告每周用于交通的自行车骑行时间比居住在高可步行性市中心的青少年多 220 分钟。郊区青少年的平均每日步数有一个显著的趋势，每天多走 1371 步。城市青少年上学的出行时间减少了 7.4 分钟。
与成年人之前的结果相反，较低的可步行性和更大的到学校的距离与比利时青少年更多的身体活动有关。因此，为成年人设计的旨在增加连通性、居住密度和连通性的物理环境干预措施可能对比利时青少年无效。
