背景户外环境的身体素质对激发儿童的健康行为很重要。我们研究了户外环境对斯德哥尔摩县11所学龄前学校4- 6岁儿童自发体力活动和紫外线（UV）辐射暴露的影响。2004年5 - 6月，对斯德哥尔摩县11所幼儿园的197名儿童进行了计步器和紫外线辐射测量。户外环境在植被、地形、空间和教育方面各不相同。收集了全球环境紫外线辐射数据，评估了自由天空和地面。记录到达、室内和室外停留以及离开。采用线性混合模型进行分析。在有树木、灌木丛和破碎地面的环境中，平均步数/分钟为21.5，在户外玩耍期间，平均暴露于紫外线辐射的比例为14.6%。在植被稀少的限定环境中，平均步数/分钟为17.7，平均紫外线暴露分数为24.3%（P < 0.001，粗）。步/分范围为8.9-30.0（女孩）和8.8-37.2（男孩），紫外线照射范围为4-60%（性别间无差异）。宽敞的幼儿园环境，树木，灌木丛和破碎的地面触发身体活动，并在户外玩耍中产生防晒保护。由于许多儿童上学前班，因此建议在社区建筑中提供这种环境。(c)2005年爱思唯尔公司All rights reserved.
Background. The physical qualities of outdoor environments are important to trigger healthy behavior in children. We studied the impact of outdoor environments upon spontaneous physical activity and exposure to ultraviolet (UV) radiation in 4- to 6-year-old children at 11 preschools in Stockholm county.Methods. In May-June 2004, pedometry and measurement of UV radiation were carried out on 197 children from 11 preschools in Stockholm county. Outdoor environments differed regarding vegetation, topography, space, and education. Ambient global UV radiation data were collected, free sky, and ground surface assessed. Arrival, in- and outdoor stay, and departure were recorded. For analysis, linear mixed model analysis was applied.Results. In environments with trees, shrubbery, and broken ground, the mean step count/min was 21.5, and mean exposure to UV radiation as fraction of available UV during play outdoors 14.6%. In delimited environments with little vegetation, the mean step count/min was 17.7 and mean exposure fraction to UV radiation 24.3% (P < 0.001, crude). Step/min range was 8.9-30.0 (girls) and 8.8-37.2 (boys), UV radiation exposure range 4-60% (no difference between genders).Conclusion. Spacious preschool environments with trees, shrubbery, and broken ground trigger physical activity and yield sun protection in outdoor play. As many children attend preschool, access to such environments is recommended in community architecture. (c) 2005 Elsevier Inc. All rights reserved.
