High family functioning is associated with reduced depression symptoms, better academic achievement, less disordered eating, and better metabolic control among youth. However, we know very little about the role of family functioning on physical activity and sedentary behavior among youth, which was the purpose of this study.
Data from the 2003 and 2011-2012 cycles of the National Survey of Children's Health were used. A total of 61,226 parents/guardians from the 2003 cycle and 40,446 parents/guardians from the 2011-2012 cycle (total n = 101,672) across all 50 states and the District of Columbia were examined. Parents answered questions related to family functioning and their child's (age 6-17 yrs) physical activity and sedentary behavior.
Results were the same across both cycles; after adjustments, youth engaged in less physical activity if the family had worse family functioning (β = -0.06, P < .001). Similarly, youth engaged in more sedentary behavior if the family had worse family functioning (β = 0.05, P < .001).
This research suggests that youth are more active and engage in less sedentary behavior if their family has greater family functioning.
家庭功能良好与青少年抑郁症状减轻、学业成绩提高、饮食失调减少以及代谢控制改善相关。然而，我们对家庭功能在青少年身体活动和久坐行为方面所起的作用知之甚少，而这正是本研究的目的。
使用了2003年以及2011 - 2012年两轮全国儿童健康调查的数据。对来自全美50个州和哥伦比亚特区的2003年调查周期中的61226名家长/监护人以及2011 - 2012年调查周期中的40446名家长/监护人（总计n = 101672）进行了调查。家长们回答了与家庭功能以及其孩子（6 - 17岁）的身体活动和久坐行为相关的问题。
两个调查周期的结果相同；经过调整后，如果家庭功能较差，青少年的身体活动就较少（β = -0.06，P <.001）。同样，如果家庭功能较差，青少年的久坐行为就较多（β = 0.05，P <.001）。
本研究表明，如果青少年的家庭功能更好，他们会更活跃，久坐行为也会更少。
