Accelerometry Response Rate.

<p>GINIplus15 and LISAPlus15 are the 15-year followups of birth cohorts GINIplus and LISAPlus. For details on GINIplus and LISAplus see von Berg et al, 2003 and 2015 [<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0152217#pone.0152217.ref024" target="_blank">24</a>–<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0152217#pone.0152217.ref026" target="_blank">26</a>]and Chen et al, 2007 [<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0152217#pone.0152217.ref019" target="_blank">19</a>] respectively. We give the number and percentage of subjects as a percentage of those contacted for accelerometry, those who gave their consent, and those who completed accelerometry and returned the device. Quality control failure includes inconsistency between diary and weartime criteria of Troiano et al, 2007 [<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0152217#pone.0152217.ref027" target="_blank">27</a>] using SAS programs published by NHANES [<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0152217#pone.0152217.ref028" target="_blank">28</a>](58% of excluded days); other non-wear time issues (27% of excluded days); and technical issues (7.4% of excluded days). Many days were invalid for more than one reason.</p

Daily Activity in German Adolescents.

<p>PE is any time between diaried start and end of school physical education (PE.) School is any time between diaried start and end of school, outside PE. Leisure Sport is any time outside of PE when the subject diaries sport. Transport is time between leaving home and arriving at school. Only the trip to school is described. Other is all other waking time when the monitor was worn. Estimates for PE and Leisure Sport include estimated moderate and vigorous activity during this period if the diary shows the device was not worn due to sport such as swimming. Calculations are based on data applying Freedson‘s vertical-axis algorithm for children from Freedson et al, 2005 [<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0152217#pone.0152217.ref033" target="_blank">33</a>] as cited in [<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0152217#pone.0152217.ref037" target="_blank">37</a>]. MVPA is moderate + vigorous physical activity.</p
