目的：比较超重和非超重3- 5岁儿童在学龄前的身体活动水平。第二个目的是评估与体重相关的差异，在假设的父母决定因素的儿童体力活动behavior.DESIGN：横断面研究subjECTS：共245，3- 5岁（127名女孩，118名男孩）和他们的父母（S）（242名母亲，173名父亲）从9个学前班招募。超重状态确定使用年龄和性别特异性的第85百分位数的身体质量指数（BMI）从CDC Growth Charts.MEASUREMENTS：在学龄前一天的身体活动进行了评估，通过两个独立的客观措施，直接观察使用的观察系统记录活动在学龄前学校（OSRAP）和实时加速度计使用MTI/CSA 7164加速度计。家长完成了带回家的调查评估社会人口信息，父母的身高和体重，体育活动的建模，支持体育活动，积极的玩具和体育器材在家里，孩子的电视观看，频率的公园参观，和儿童capability.RESULTS的看法：超重的男孩显着不活跃比他们的nonoverweight同龄人在学龄前一天。在女孩中没有观察到显著差异。尽管儿童超重状态和父母肥胖之间有很强的关联，没有显着差异观察到的假设父母的影响对体力活动behaviors.CONCLUSIONS：我们的研究结果表明，一个显着比例的超重儿童可能会增加风险，因为在学龄前一天的体力活动水平低，进一步增加肥胖。
OBJECTIVE: To compare the physical activity levels of overweight and non overweight 3- to 5-y-old children while attending preschool. A secondary aim was to evaluate weight-related differences in hypothesized parental determinants of child physical activity behavior.DESIGN: Cross-sectional study.SUBJECTS: A total of 245, 3- to 5-y-olds ( 127 girls, 118 boys) and their parent(s) ( 242 mothers, 173 fathers) recruited from nine preschools. Overweight status determined using the age- and sex-specific 85th percentile for body mass index (BMI) from CDC Growth Charts.MEASUREMENTS: Physical activity during the preschool day was assessed on multiple days via two independent objective measures-direct observation using the observation system for recording activity in preschools ( OSRAP) and real-time accelerometry using the MTI/CSA 7164 accelerometer. Parents completed a take-home survey assessing sociodemographic information, parental height and weight, modeling of physical activity, support for physical activity, active toys and sporting equipment at home, child's television watching, frequency of park visitation, and perceptions of child competence.RESULTS: Overweight boys were significantly less active than their nonoverweight peers during the preschool day. No significant differences were observed in girls. Despite a strong association between childhood overweight status and parental obesity, no significant differences were observed for the hypothesized parental influences on physical activity behavior.CONCLUSIONS: Our results suggest that a significant proportion of overweight children may be at increased risk for further gains in adiposity because of low levels of physical activity during the preschool day.
