Objective.确定儿童的身体活动的比例发生在公共公园与游乐场。从新西兰达尼丁两个低社会经济地位社区的学校招募5至10岁的儿童（n = 184）。使用加速度计（Actigraph GT 1 M）和全球定位系统（Globalsat DG-100）来量化和识别7天内发生的身体活动。横断面数据收集于2007年10月至12月（南半球春季），并在学校测量儿童的身高和体重。至少84%的参与者每天至少有5个或更多小时的加速度计和全球定位系统数据，持续4天。总体而言，1.9%的记录活动发生在城市公园（95%置信区间：1.4，2.4），虽然这是2.7%（95%置信区间：0.7，4.6）肥胖儿童。加速计和全球定位系统数据能够成功地记录和匹配在这个年龄组。儿童在有游乐场的公园里活动的比例很低，尽管这对某些分组来说可能仍然很重要。(C)2010年爱思唯尔公司All rights reserved.
Objective. To identify the proportion of children's physical activity occurring in public parks with playgrounds.Methods. Children (n = 184) aged 5 to 10 years were recruited from schools located in two low socioeconomic status communities in Dunedin, New Zealand. Accelerometers (Actigraph GT1M) and global positioning system units (Globalsat DG-100) were used to quantify and identify where physical activity had occurred over a 7-day period. Cross-sectional data were collected October to December 2007 (southern hemisphere spring) and the child's height and weight were measured at school.Results. At least 84% of participants had accelerometer and global positioning system data available for five or more hourly periods per day, for at least 4 days. Overall, 1.9% of recorded activity took place at city parks (95% confidence interval: 1.4, 2.4), although this was 2.7% (95% confidence intervals: 0.7, 4.6) among obese children.Conclusions. Accelerometers and GPS data was able to be successfully recorded and matched among this age group. The proportion of children's activity taking place in parks with playgrounds was low, although this may still be important for some subgroups. (C) 2010 Elsevier Inc. All rights reserved.
