目的探讨影响儿童早期生活质量的因素设计前瞻性队列研究。设置雅芳家长和儿童的纵向研究，英国。参与者雅芳父母和儿童纵向研究的11-12岁儿童。主要结果测量每分钟计数（cpm）的身体活动水平和分钟的中度到剧烈的体力活动，7天测量与单轴activgraph accelerometer.Results有效activgraph数据，定义为至少3天的体力活动，每天至少10小时，收集了5451名儿童。有几个因素与11-12岁的身体活动有关。将回归系数与分类变量的基线“无”进行比较：妊娠期间母亲快走（回归系数5.0，95%置信区间-8.5至18.5;
Objective To examine factors in early life (up to age 5 years) that are associated with objectively measured physical activity in 11-12 year olds.Design Prospective cohort study.Setting Avon longitudinal study of parents and children, United Kingdom.Participants Children aged 11-12 years from the Avon longitudinal study of parents and children.Main outcome measure Physical activity levels in counts per minute (cpm) and minutes of moderate to vigorous physical activity for seven days measured with a uniaxial actigraph accelerometer.Results Valid actigraph data, defined as at least three days of physical activity for at least 10 hours a day, were collected from 5451 children. Several factors were associated with physical activity at ages 11-12 years. Regression coefficients are compared with the baseline of "none" for categorical variables: maternal brisk walking during pregnancy (regression coefficient 5.0, 95% confidence interval -8.5 to 18.5; cpm for
