The purpose of this study was to investigate the relationship between the childcare environment and physical activity and sedentary behavior of toddlers and preschoolers. A total of 68 toddlers (1.0-2.9 years) and 233 preschoolers (3.0-5.9 years) were recruited from 11 childcare services in 2013 within the Illawarra and Shoalhaven region of NSW, Australia. For this study analysis was conducted in 2016. The childcare environment was assessed using the Environment and Policy Assessment Observation (EPAO) instrument, and childcare services categorized as low, medium, or high based on their scores. Time spent in physical activity and sitting was assessed over one week using activPAL accelerometers. Relationship between EPAO and children's physical activity and sedentary behavior was assessed using multilevel mixed-effects linear regression. Toddlers who attended high EPAO services sat more (8.73 min [- 10.26, 27.73]) and stood less (- 13.64 min [- 29.27, 2.00]) than those who attended low EPAO services. Preschoolers who attended high EPAO services sat less than those in low and medium services (mean [95%CI] = - 7.81 min [- 26.64, 11.02]). Sub-categories of the EPAO that were associated with less time sitting were: sedentary environments for toddlers and portable play equipment for preschoolers. This study extends previous research by identifying differences between toddlers and preschooler's physical activity and sedentary behaviors in relation to childcare environments. A greater understanding of how the childcare environment relates to sitting time for both toddlers and preschool aged children is needed.
本研究的目的是调查儿童保育环境与幼儿及学龄前儿童身体活动和久坐行为之间的关系。2013年,从澳大利亚新南威尔士州伊拉瓦拉和肖尔黑文地区的11家儿童保育服务机构招募了68名幼儿(1.0 - 2.9岁)和233名学龄前儿童(3.0 - 5.9岁)。本研究分析于2016年进行。使用环境与政策评估观察(EPAO)工具对儿童保育环境进行评估,并根据得分将儿童保育服务机构分为低、中、高三个类别。使用activPAL加速度计在一周内评估身体活动和久坐所花费的时间。使用多水平混合效应线性回归评估EPAO与儿童身体活动和久坐行为之间的关系。与参加低EPAO服务的幼儿相比,参加高EPAO服务的幼儿久坐时间更长(8.73分钟[-10.26, 27.73]),站立时间更短(-13.64分钟[-29.27, 2.00])。与参加低EPAO服务的学龄前儿童相比,参加高EPAO服务的学龄前儿童久坐时间更少(均值[95%置信区间]= -7.81分钟[-26.64, 11.02])。与久坐时间减少相关的EPAO子类别为:幼儿的久坐环境和学龄前儿童的便携式游乐设备。本研究通过识别幼儿和学龄前儿童在身体活动和久坐行为方面与儿童保育环境的差异,扩展了先前的研究。需要更深入地了解儿童保育环境与幼儿及学龄前儿童久坐时间之间的关系。
