Abstract

BACKGROUND

Research in adults shows poor agreement between self-reported and objectively measured proximity to physical activity resources; however there is little such research in adolescents. This study assessed the level of agreement between self-reported and objective measures of distance to physical activity resources in adolescents; and whether perceived or actual distance was related to actual use and physical activity levels.

METHODS

110 New Zealand high school students (12-18 years) were asked the time (in minutes) it would take them to walk from their home to the nearest physical activity resource, and whether they had used it in the previous month. The distance from participants' homes to the nearest resource was measured using GIS. Physical activity was assessed with accelerometers.

RESULTS

Agreement was poor, with weighted Kappa Indices ranging from 0.1 to 0.4. The facilities used most frequently were schools (90%), public parks (76%), and playing fields (74%). Closer location was associated with higher use of some facilities only. Moderate-to-vigorous activity levels were not associated with self-reported or measured distance.

CONCLUSIONS

Agreement between perceived and measured access is poor among adolescents. Further research is needed to understand how individual and social factors interact with environmental factors and whether improving awareness improves use.

摘要

背景

成人研究表明,自我报告的与客观测量的接近身体活动资源之间的一致性较差;然而,青少年的此类研究很少。本研究评估了青少年自我报告和客观测量的身体活动资源距离之间的一致性程度;以及感知距离或实际距离与实际使用和身体活动水平的关系。

方法

110 名新西兰高中生(12-18 岁)被问到他们从家到最近的身体活动资源所需的时间(分钟),以及他们在过去一个月是否使用过该资源。使用 GIS 测量参与者家到最近资源的距离。使用加速度计评估身体活动。

结果

一致性较差,加权 Kappa 指数范围为 0.1 至 0.4。使用最频繁的设施是学校(90%)、公园(76%)和运动场(74%)。只有一些设施的位置较近与更高的使用率相关。中度至剧烈活动水平与自我报告或测量的距离无关。

结论

青少年对感知和测量的可达性的一致性较差。需要进一步研究,以了解个人和社会因素如何与环境因素相互作用,以及提高意识是否会提高使用率。
