The purpose of this study was to examine the association between parent and adolescent levels of physical activity, sedentary behaviors, and sleep among a group of overweight and obese adolescents.
Baseline data of parent-adolescent pairs who enrolled in a lifestyle modification intervention were analyzed for this study (n = 176). Participants completed questionnaires about their screen time (TV, video game, and computer time), wore an accelerometer for 8 days, and completed a sleep diary for 1 week. In total, 98 parent-adolescent dyads provided valid data for the analyses. Multivariable regression analyses were conducted to assess the relationship between parent and adolescent's moderate-to-vigorous activity (MVPA), step counts, sedentary behaviors, and sleep duration. Analyses were split by weekday, weekday evening and weekend.
Parent-adolescent MVPA was significantly associated on weekdays (b = 0.18; SE = 0.08; β = 0.26), weekday evenings (b = 0.21; SE = 0.08; β = 0.28), and weekends (b = 0.29; SE = 0.12; β = 0.27). This study found associations between parent-child video game time on weekends (b = 1.10; SE = 0.49; β = 0.24) and computer time on weekdays (b = 0.42; SE = 0.19; β = 0.23). Adolescent sleep was associated with parental sleep on weekdays only (b = 0.38; SE = 0.09; β = 0.46).
The findings warrant further investigation into the direction and mechanism of the relationship between parent and adolescent weight related behaviors.
本研究旨在探讨一组超重和肥胖青少年中父母与青少年的身体活动水平、久坐行为和睡眠之间的关联。
对参加生活方式改变干预的亲子对的基线数据进行了本研究分析(n = 176)。参与者完成了关于他们屏幕时间(电视、电子游戏和电脑时间)的问卷,佩戴加速度计8天,并完成了1周的睡眠日记。总共98对亲子提供了有效的分析数据。进行多变量回归分析以评估父母与青少年的中度至剧烈活动(MVPA)、步数、久坐行为和睡眠时间之间的关系。分析按工作日、工作日晚上和周末进行划分。
父母与青少年的MVPA在工作日(b = 0.18;SE = 0.08;β = 0.26)、工作日晚上(b = 0.21;SE = 0.08;β = 0.28)和周末(b = 0.29;SE = 0.12;β = 0.27)均有显著关联。本研究发现周末亲子电子游戏时间(b = 1.10;SE = 0.49;β = 0.24)与工作日电脑时间(b = 0.42;SE = 0.19;β = 0.23)之间存在关联。青少年睡眠仅与工作日的父母睡眠有关(b = 0.38;SE = 0.09;β = 0.46)。
这些发现值得进一步研究父母与青少年体重相关行为之间关系的方向和机制。
