To examine psychosocial and environmental correlates of active commuting to university (ACU) and explore its association with overall physical activity among college students.
The sample included 518 students (mean 22.4 years; 59.7% female) from two universities in Valencia, Spain. Weekly estimations of energy expenditure from ACU and total physical activity were obtained. Socio-economic status, self-efficacy, barriers to active transport, access to car and motorbike, access to public transport, walking and cycling facilities and distance to university were assessed. Data were collected April and May of 2009, using a self-administered survey. A structural equation model was used to analyze associations among variables.
ACU was inversely correlated with access to private motorized transport (car or motorbike). Perception of physical self-efficacy and walking and cycling facilities were positively associated with ACU, while planning/psychosocial barriers were negatively associated. Multivariate modelling explained 19% of variance in ACU. ACU was not related to total daily physical activity.
Both psychological and environmental variables were significant correlates of ACU. Present findings provide an empirical basis for interventions to increase active transport among university students.
探讨与大学生主动通勤（ACU）相关的社会心理和环境因素，并探究其与总体身体活动的关系。
该研究样本包括来自西班牙巴伦西亚两所大学的 518 名学生（平均年龄 22.4 岁，59.7%为女性）。每周对 ACU 和总身体活动的能量消耗进行估计。评估了社会经济地位、自我效能感、主动交通障碍、汽车和摩托车的获取情况、公共交通的获取情况、步行和骑行设施以及到大学的距离。数据于 2009 年 4 月和 5 月通过自我管理调查收集。使用结构方程模型分析变量之间的关联。
ACU 与私人机动交通工具（汽车或摩托车）的获取呈负相关。身体自我效能感和步行和骑行设施的感知与 ACU 呈正相关，而计划/心理障碍则与 ACU 呈负相关。多变量模型解释了 ACU 19%的变异性。ACU 与总日身体活动无关。
心理和环境变量都是 ACU 的重要相关因素。本研究结果为在大学生中增加主动交通提供了实证依据。
