      abstract     = {Physical activity is a complex behavior that is difficult
                      to measure validly and reliably in large, population-based
                      studies. Data on physical activity are available for the
                      initial 100,000 participants of the German National
                      Cohort.To describe the baseline physical activity assessment
                      in the cohort and to present initial descriptive
                      results.Physical activity was assessed using a combination
                      of tools, including two self-administered questionnaires,
                      the Questionnaire on Annual Physical Activity Pattern (QUAP)
                      and the Global Physical Activity Questionnaire (GPAQ);
                      a computer-based 24‑h physical activity recall (cpar24);
                      and 7‑day accelerometry (Actigraph GT3X/+; ActiGraph,
                      Pensacola, FL, USA).The availability of data varied between
                      assessment instruments (QUAP: n = 16,372; GPAQ:
                      n = 90,900; cpar24: n = 23,989; accelerometry:
                      n = 35,218). Analyses across measurement tools showed
                      that on average, women spent 75 to 216 min/d, and men
                      spent 73 to 224 min/d in moderate or higher intensity
                      total physical activity. Persons aged 20-39 years spent 66
                      to 200 min/d, and persons aged 40-69 years spent 78 to
                      244 min/d in moderate or higher intensity total physical
                      activity.Initial baseline analyses of physical activity in
                      this cohort show the value of using a combination of
                      questionnaires, 24‑h recalls, and a movement sensor. The
                      comprehensive data collection represents a valuable
                      resource for future analyses and will improve our
                      understanding of the association between physical activity
                      and disease prevention.},
