背景：目前尚不清楚幼儿的父母报告的体力活动和久坐时间是否与直接测量相关。本研究的目的是比较父母报告的身体和久坐活动与直接测量的加速度计数据在早期childhood.METHODS：从2013年至2014年，117名健康儿童不到6岁，被招募到佩戴7天的主动加速度计。对87名儿童（74%）进行了加速度计数据和问卷调查。平均每日体力活动定义为每分钟≥100计数的活动总和，久坐时间定义为活动总和
BACKGROUND: It is unknown if young children's parent-reported physical activity and sedentary time are correlated with direct measures. The study objectives were to compare parent-reported physical and sedentary activity versus directly measured accelerometer data in early childhood.METHODS: From 2013 to 2014, 117 healthy children less than 6 years of age were recruited to wear Actical accelerometers for 7 days. Accelerometer data and questionnaires were available on 87 children (74%). Average daily physical activity was defined as the sum of activity ≥100 counts per minute, and sedentary time as the sum of activity
