本研究旨在探讨学龄前体育活动对儿童从学龄前到小学一年级身体肥胖的影响。Fragrance儿童研究是一项关于儿童心血管危险行为的纵向研究，始于1987年，106名3-5岁儿童及其父母参加了这项研究。使用电子运动传感器每年评估两次身体活动，为期5天。作者通过使用三头肌和肩胛下皮褶的斜率和体重指数估计儿童从学前到一年级的体脂水平变化。平均而言，活跃的女孩（即，那些活动水平高于中位数的人）从基线到一年级，他们的三头肌皮褶增加了1.0 mm，而不活动的女孩增加了1.75 mm。活跃的男孩三头肌平均减少了0.75 mm，而不活动的男孩增加了0.25 mm。当年龄、看电视、能量摄入、基线三头肌和父母的体重指数被控制时，不活跃的学龄前儿童在随访期间具有增加的三头肌斜率（而不是稳定或减小的斜率）的可能性是活跃的学龄前儿童的3.8倍（95%置信区间1.4-10.6）。对于基线时体脂较多的儿童，这种相对风险估计值略高。在这项研究中，学龄前儿童与低水平的身体活动获得了更多的皮下脂肪比更多的活动的儿童。
This study examined the effect of preschool physical activity on the change in body fatness from preschool to first grade, The Framingham Children's Study, a longitudinal study of childhood cardiovascular risk behaviors, began in 1987 with the enrollment of 106 children aged 3-5 years and their parents, The present analyses include 97 healthy children with complete data from study entry into first grade, Physical activity was assessed twice yearly for 5 days with an electronic motion sensor, The authors estimated change in the child's level of body fat from preschool to first grade by using the slopes of triceps and subscapular skinfolds and body mass index, On average, active girls (i.e., those with above-median activity levels) gained 1.0 mm in their triceps skinfolds from baseline to first grade, while inactive girls gained 1.75 mm. Active boys lost an average of 0.75 mm in their triceps, while inactive boys gained 0.25 mm. When age, television viewing, energy intake, baseline triceps, and parents' body mass indices were controlled for, inactive preschoolers were 3.8 (95% confidence interval 1.4-10.6) times as likely as active preschoolers to have an increasing triceps slope during follow up (rather than a stable or decreasing slope). This relative risk estimate was slightly higher for children with more body fat at baseline. In this study, preschool-aged children with low levels of physical activity gained substantially more subcutaneous fat than did more active children.
