This study examined the associations of the perceived and objective environment with adolescent engagement in sports activities and walking and cycling in leisure time. It also explored the degree of agreement between objective and perceived availability of physical activity (PA) facilities in neighborhoods.
Cross-sectional data on physical activity, the perceived availability of physical activity opportunities (perceived physical environment) was assessed through a questionnaire and the objective availability of PA opportunities (objective physical environment) was obtained through GIS data. The final sample included 654 adolescents with a mean age of 14.1 (SD = 1.2) years.
Perceived availability of sports facilities and parks was significantly associated with engaging in sports (OR: 1.73; 95% CI: 1.16-2.56) and with walking and cycling in leisure time (OR: 1.66; 95% CI: 1.07-2.57) respectively. Agreement between objective and perceived environment was low to moderate with Kappa values ranging from -0.005 to 0.053.
The perceived environment was the stronger correlate of PA behavior among adolescents. There were substantial differences between assessments of objective and perceived physical environment.
本研究考察了感知环境和客观环境与青少年参与体育活动和休闲时间步行和骑自行车的关系。它还探讨了邻里间体力活动设施客观可及性和感知可及性之间的一致性程度。
横断面数据显示，青少年的体力活动以及对体力活动机会的感知可及性（感知物理环境）通过问卷进行评估，而体力活动机会的客观可及性（客观物理环境）则通过 GIS 数据获得。最终样本包括 654 名平均年龄为 14.1（SD=1.2）岁的青少年。
感知到的体育设施和公园的可及性与参与体育活动（OR：1.73；95%CI：1.16-2.56）和休闲时间步行和骑自行车（OR：1.66；95%CI：1.07-2.57）显著相关。客观环境和感知环境之间的一致性低至中度，Kappa 值范围为-0.005 至 0.053。
感知环境是青少年体力活动行为的更强相关因素。客观和感知物理环境的评估之间存在很大差异。
