The preschool that children attend has been shown to be a significant but variable predictor of physical activity of 3- to 5-yr-olds, whereas the time outdoors has been found to be a strong correlate of physical activity. Researchers speculate that variations in preschool physical activity may be attributed to variations in preschool policies and practices, including the form and content of outdoor physical environments. However, assessment methods linking them to physical activity are limited. Improved understanding of links between environment and activity could be used to influence childcare policy, which is highly regulated, usually at state level, to create outdoor environments more conducive to children's informal play and physical activity. The purpose of this article was to introduce behavior mapping as a direct observation method on the basis of the theories of behavior setting and affordance and to demonstrate its sensitivity to gathering physical activity and associated environmental data at a sufficiently detailed level to affect built environment design policy.
Behavior mapping data, including outdoor environmental characteristics and children's physical activity levels, were obtained in two preschool centers at the Research Triangle region, NC.
Physical activity levels at the two centers varied across different types of behavior settings, including pathways, play structures, and open areas. The same type of setting with different attributes, such as circular versus straight pathways, and open areas with different ground surfaces, such as asphalt, compacted soil, woodchips, and sand, attracted different levels of physical activity.
Behavior mapping provides a promising method for objectively measuring relationships between physical behavior settings and directly associated activity levels.
研究表明,儿童就读的幼儿园是 3 至 5 岁儿童身体活动的重要但可变的预测因素,而户外活动时间是身体活动的强相关因素。研究人员推测,幼儿园身体活动的变化可能归因于幼儿园政策和实践的变化,包括户外物理环境的形式和内容。然而,将它们与身体活动联系起来的评估方法有限。更好地了解环境与活动之间的联系,可以用来影响儿童保育政策,该政策受到高度监管,通常由州一级制定,以创建更有利于儿童非正式游戏和身体活动的户外环境。本文的目的是介绍行为映射作为一种基于行为设置和可供性理论的直接观察方法,并展示其在以足够详细的水平收集身体活动和相关环境数据方面的敏感性,以影响建筑环境设计政策。
在北卡罗来纳州研究三角区的两个幼儿园中心获得了行为映射数据,包括户外环境特征和儿童的身体活动水平。
两个中心的身体活动水平在不同类型的行为设置中有所不同,包括路径、游乐结构和开阔区域。具有不同属性的同一类型的设置,例如圆形与直线路径,以及具有不同地面表面的开阔区域,例如沥青、压实土壤、木屑和沙子,吸引了不同水平的身体活动。
行为映射为客观测量身体行为环境与直接相关的活动水平之间的关系提供了一种很有前途的方法。
