目的：探讨影响幼儿体力活动的相关因素。研究设计：参与者，214名儿童（年龄3-5岁）参加了10个托儿中心，监测身体活动与加速度计在连续2天（48小时）。测定平均每日活动计数、上午9点至下午5点之间的活动计数以及剧烈活动所花费的时间百分比。调查的因素包括年龄、托儿中心、季节、性别、体重指数（BMI）、早产史、参加有组织的活动、父母BMI和父母教育水平。回归分析用于确定与每个活动措施相关的因素。结果如下：一个统计模型，包括性别，早产史，儿童保育中心，和父亲的BMI占22%，37%，和23%的方差，每天总计数，计数之间的上午9时至下午5时，和时间的百分比，在每天剧烈活动，分别。儿童保育中心是最高的个人预测活动。除了上午9点到下午5点之间的计数外，男孩在所有活动措施中比女孩更活跃。早产儿比足月儿活动少，孩子的高活动水平与父亲的低BMI相关。结论：研究结果表明，性别，早产史，托儿中心和父亲的BMI影响幼儿的日常体力活动。
Objective: Our purpose was to identify factors associated with the physical activity in young children. Study design: Participants,were 214 children (aged 3-5 years) enrolled in 10 childcare centers who were monitored for physical activity with an accelerometer during 2 continuous days (48 hours). Mean daily activity counts, activity counts between 9 AM and 5 PM, and percentage of time spent in vigorous activity were determined. The factors investigated were age, childcare center, season, sex, body mass index (BMI), history of preterm birth, participation in organized activities, parental BMI, and parental educational level. Regression analyses were used to identify factors associated with each of the activity measures. Results: A statistical model including sex, history of preterm birth, childcare center, and father's BMI accounted for 22%, 37%, and 23% of the variance in total daily counts, counts between 9 AM and 5 PM, and percentage of time spent in daily vigorous activity, respectively. Childcare center was the highest individual predictor of activity. Boys were more active than girls in all activity measures except counts between 9 AM and 5 PM. Children born preterm were less active than children born at term, and high activity levels in the child were associated with a low BMI in fathers. Conclusion: The findings indicate that sex, history of preterm birth, childcare center, and father's BMI influence the daily physical activity of young children.
