父母对健身和锻炼的鼓励和态度在青少年的体育活动和久坐行为习惯中发挥的长期作用尚不清楚。本文旨在纵向考察父母鼓励参加体育活动和父母对保持健康的关注与五年后青少年的体育活动和久坐行为习惯之间的关系。项目EAT-II青少年和青年参与者(1130名男性，1386名女性)在初中或高中(1998-1999年)完成了调查，并在5年后再次完成了调查。参与者被问及他们的父母是否鼓励他们进行体育活动，并关心保持健康和锻炼。评估青少年适度和剧烈的身体活动(MVPA)和观看电视/视频(小时/周)。调整社会人口学特征和基线行为的线性回归模型被用来检验五年后青少年和年轻人(时间2)父母因素与行为结果的关联。在对社会人口学特征和基线MVPA进行调整后，在年轻成年男性中，青春期报告的母亲和父亲鼓励积极活动以及父亲对健康的关心与五年后每周MVPA的小时数呈正相关(Trend≤.01)。在高中年龄组中，母亲鼓励与MVPA呈显著正相关(p趋势=0.06)，在高中年龄组男性中，父亲鼓励与MVPA呈正相关(p趋势=0.02)。在年轻女性中，母亲鼓励积极活动与减少电视/视频时间有关(趋势=0.02)，而其他父母因素与其他组中较少的电视/视频时间无关。5年后，父母鼓励参加体育活动的男性和年轻女性的体力活动增加有关。年龄较小的青少年似乎特别受同性父母的影响。这些发现表明，鼓励可能比父母对健康的关心对青少年的体育活动习惯影响更大。还需要进一步的研究来确定父母如何帮助青少年减少久坐的行为时间。
The long-term role that parental encouragement and attitudes about fitness and exercise play in adolescents' physical activity and sedentary behavior habits remains unclear. This paper aims to longitudinally examine how parental encouragement to be physically active and parental concern about staying fit are associated with adolescents' physical activity and sedentary behavior habits five years later. Project EAT-II adolescent and young adult participants (1130 male, 1386 female) completed surveys while in middle school or high school (1998–1999), and again 5 years later. Participants were asked whether their mother and father encourage them to be physically active and care about staying fit and exercising. Adolescent moderate and vigorous physical activity (MVPA) and TV/video watching (hours/week) were assessed. Linear regression models adjusted for socio-demographic characteristics and baseline behavior were used to examine the association of Time 1 parental factors with behavioral outcomes among adolescents and young adults five years later (Time 2). After adjustment for socio-demographic characteristics and baseline MVPA, adolescent-reported maternal and paternal encouragement to be active, and paternal care for fitness, were positively associated with weekly hours of MVPA after five years in young adult males (p for trend ≤ .01). The positive relationship between maternal encouragement and MVPA approached significance among high-school aged females (p for trend = .06), and paternal encouragement was positively related to MVPA among high-school aged males (p for trend = .02). While maternal encouragement to be active was associated with decreased TV/video time among younger females (p for trend = .02), other parental factors were not associated with lower TV/video time among the other groups. Parental encouragement to be active was associated with increased physical activity among males and younger females 5 years later. Younger adolescents appear to be especially influenced by their same-sex parent. These findings suggest that encouragement may be more influential than parental concern for fitness on adolescents' physical activity habits. Further research is needed to determine how parents can help adolescents decrease sedentary behavior time.
