Parents influence the physical activity and sedentary behaviour of their children. This analysis examines associations between parental role modeling and support and children's physical activity and sedentary behaviour.
The sample consists of 1,328 biological parent-child pairs from the first three cycles of the Canadian Health Measures Survey (2007 through 2013). Data on physical activity and sedentary behaviour were collected using a questionnaire and by accelerometer. Pearson correlation and linear regression analyses were completed to examine associations between parents' and children's measured physical activity and sedentary time and reported screen-based activities. Analyses were adjusted for variables indicating parental support and household lifestyle characteristics.
Accelerometer-measured physical activity and sedentary time were correlated in all parent-child pairs. Parents' measured moderate-to-vigorous physical activity (MVPA) was associated with children's MVPA (ß = 0.28, p < 0.001). For every 20-minute increase in a parent's MVPA, the child's MVPA increased by 5 to 10 minutes. Parents' measured sedentary time was associated with that of their daughters on weekends, and with that of their sons during the after-school period. Parents' reported screen time was associated with that of their daughters.
This study confirms parents' influence on their children's physical activity. Parental role modeling and support have independent effects on a child's level of physical activity.
父母会影响其子女的身体活动和久坐行为。本分析探讨了父母榜样作用和支持与儿童身体活动和久坐行为之间的关系。
该样本由加拿大健康测量调查（2007 年至 2013 年）的前三个周期中的 1328 对亲生父母-子女对组成。使用问卷和加速度计收集身体活动和久坐行为的数据。完成了 Pearson 相关性和线性回归分析，以检查父母和孩子的身体活动和久坐时间以及报告的基于屏幕的活动之间的关联。分析调整了表明父母支持和家庭生活方式特征的变量。
在所有亲子对中，加速度计测量的身体活动和久坐时间均呈相关性。父母的中等到剧烈体力活动（MVPA）与孩子的 MVPA 相关（β=0.28，p<0.001）。父母的 MVPA 每增加 20 分钟，孩子的 MVPA 就会增加 5 到 10 分钟。父母的久坐时间与女儿在周末的久坐时间有关，与儿子在放学后的久坐时间有关。父母的屏幕时间与女儿的屏幕时间有关。
本研究证实了父母对子女身体活动的影响。父母的榜样作用和支持对孩子的身体活动水平有独立的影响。
