BACKGROUND
Regular physical activity is important for remaining healthy. Most studies on the association between active child- and adulthood were based on small non-representative populations. The purpose of the study was to quantify tracking of leisure-time PA (in and outside sports clubs) for 6 years from adolescence into young adulthood in a representative sample in Germany.
METHODS
This study was a subsample of the "Motorik-Modul (MoMo) Longitudinal Study" (baseline: 2003-2006, wave 1: 2009-2012). Representative longitudinal physical activity data of N = 947 adolescents were included and collected using the MoMo-physical activity questionnaire (MoMo-PAQ). Stability of different physical activity indices was measured using Spearman's rank-order correlations and ANOVA with repeated measurement with age, sex and socio-economic status (SES) as determinants.
RESULTS
While mean leisure-time physical activity outside sports clubs (LTPA) (F(1,397) = 7.9, df = 1; p < .01), sports club physical activity (SCPA) (F(387) = 4.8, df = 1; p < .05) and overall physical activity (OPA) (F(1,441) = 7.7, df = 1; p < .01) changed significantly over time, no changes in overall sports index (OS index) (F(371) = 3.2, df = 1; p > .05) were observed. Low tracking correlations were found for different physical activity indices (LTPA: r = .094, p < .05; SCPA: r = .248 p = <.05; OPA: r = .211 p < .05; OS index: r = .266 p < .05). Results by sex, age and SES were inconsistent. Analyses of agreement showed different results for determinants and settings.
CONCLUSION
The results of this representative study were comparable to previous studies and showed significant but low stability. Possible reasons for low stability coefficients are a relatively long timespan between both measurement points and potential effects of the reliability of subjective assessment methods. The results confirm that physical activity is a fluctuating variable. Future studies should examine the determinants of tracking and change in physical activity.
背景
规律的体育活动对保持健康很重要。大多数关于儿童期与成年期体育活动之间关联的研究是基于小型的非代表性人群。本研究的目的是在德国的一个代表性样本中，量化从青春期到青年期6年间休闲时间体育活动（在体育俱乐部内外）的追踪情况。
方法
本研究是“运动模块（MoMo）纵向研究”的一个子样本（基线：2003 - 2006年，第1波：2009 - 2012年）。纳入了N = 947名青少年具有代表性的纵向体育活动数据，并使用MoMo体育活动问卷（MoMo - PAQ）进行收集。使用斯皮尔曼等级相关和以年龄、性别和社会经济地位（SES）为决定因素的重复测量方差分析来测量不同体育活动指标的稳定性。
结果
虽然体育俱乐部外的平均休闲时间体育活动（LTPA）（F(1,397) = 7.9，自由度 = 1；p <.01）、体育俱乐部体育活动（SCPA）（F(387) = 4.8，自由度 = 1；p <.05）和总体体育活动（OPA）（F(1,441) = 7.7，自由度 = 1；p <.01）随时间有显著变化，但总体体育指数（OS指数）（F(371) = 3.2，自由度 = 1；p >.05）未观察到变化。不同体育活动指标的追踪相关性较低（LTPA：r =.094，p <.05；SCPA：r =.248，p <.05；OPA：r =.211，p <.05；OS指数：r =.266，p <.05）。按性别、年龄和SES划分的结果不一致。一致性分析在决定因素和环境方面显示出不同的结果。
结论
这项代表性研究的结果与先前的研究相当，显示出显著但较低的稳定性。稳定性系数较低的可能原因是两个测量点之间的时间跨度相对较长以及主观评估方法可靠性的潜在影响。结果证实体育活动是一个波动的变量。未来的研究应考察体育活动追踪和变化的决定因素。
