在一组222名学龄前儿童中，研究了人口统计学、环境和亲子互动与体力活动的相关性。活动水平的评估系统，量化直接观察到的身体活动在自然环境中。使用回归建模程序，结果显示（a）儿童的相对体重，父母的体重状况，和户外（环境）和（B）儿童的活动水平花费的时间的百分比之间的显着关系。父母肥胖与儿童的体力活动水平较低相关，儿童相对体重与体力活动水平略高相关，更多的户外活动与更高的活动水平相关。父母参与儿童的活动也显着互动与父母的肥胖水平在预测活动水平。那些有50%肥胖风险的孩子（定义为父母双方，一方或双方都超重）在亲子互动水平上的活动变化很小，而那些肥胖风险较高的孩子随着亲子互动的增加而增加活动。结果进行了讨论，并检查这些研究结果对未来的干预工作的影响。
Examined demographic, environmental, and parent-child interactional correlates of physical activity in a group of 222 preschoolers. Activity levels were assessed with a system that quantified directly observed physical activity in the natural environment. Using regression-modeling procedures, results revealed a significant relationship between (a) child's relative weight, parental weight status, and percentage of time spent outdoors (environment) and (b) children's activity levels. Parental obesity was associated with lower levels of physical activity in children, childhood relative weight was associated with slightly higher levels of physical activity, and more outdoor activity was associated with higher activity levels. Parental participation in children's activities also significantly interacted with levels of parental obesity in predicting activity levels. Those children with a 50% risk for obesity (as defined by both, one, or neither parent being overweight) had small changes in activity across levels of parent-child interaction, whereas those at higher risk for obesity responded with increased activity as parent-child interactions increased. Results are discussed, and the implications of these findings for future intervention efforts are examined.
