The study aimed to objectively characterize PA patterns and their effect on weight trajectory in adolescent AN patients. (2) Methods: PA was assessed in 47 patients on admission to inpatient treatment, in n = 25 of these patients again 4 weeks after discharge (follow-up, FU), as well as in 20 adolescent healthy controls using the Sense Wear\u2122 armband. The following PA categories were defined by metabolic equivalent (MET) ranges: sedentary behavior (SB), light (LPA), moderate (MPA), vigorous (VPA), and high-level PA (HLPA= MPA + VPA). (3) Results: LPA on admission was significantly higher in AN patients than in controls (103 vs. 55 min\/d, p &lt; 0.001), and LPA in AN decreased over time to 90 min\/d (p = 0.006). Patients with higher admission LPA (n = 12) still had elevated LPA at FU (p = 0.003). High admission LPA was associated with a higher inpatient BMI percentage gain (\u0394BMI%; 18.2% \u00b1 10.0% vs. 12.0% \u00b1 9.7%, p = 0.037) but with a loss of \u0394BMI% at FU (\u22122.3% \u00b1 3.6% vs. 0.8% \u00b1 3.6%, p = 0.045). HLPA at baseline was associated with a lower inpatient \u0394BMI% (p = 0.045). (4) Conclusion: Elevated LPA in AN patients decreased after inpatient treatment, and PA patterns had an impact on weight trajectory.<\/jats:p>","DOI":"10.3390\/jcm9030727","type":"journal-article","created":{"date-parts":[[2020,3,9]],"date-time":"2020-03-09T05:37:34Z","timestamp":1583732254000},"page":"727","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Assessment of Physical Activity Patterns in Adolescent Patients with Anorexia Nervosa and Their Effect on Weight Gain"],"prefix":"10.3390","volume":"9","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1478-8997","authenticated-orcid":false,"given":"Miriam","family":"Kemmer","sequence":"first","affiliation":[{"name":"Department of Child and Adolescent Psychiatry, Charit\u00e9-Universit\u00e4tsmedizin Berlin, Corporate Member of Freie Universit\u00e4t Berlin, Humboldt-Universit\u00e4t zu Berlin, and Berlin Institute of Health, 13353 Berlin, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christoph U.","family":"Correll","sequence":"additional","affiliation":[{"name":"Department of Child and Adolescent Psychiatry, Charit\u00e9-Universit\u00e4tsmedizin Berlin, Corporate Member of Freie Universit\u00e4t Berlin, Humboldt-Universit\u00e4t zu Berlin, and Berlin Institute of Health, 13353 Berlin, Germany"},{"name":"Donald and Barbara Zucker School of Medicine at Hofstra\/Northwell, Hempstead, NY 11549, USA"},{"name":"Department of Psychiatry, The Zucker Hillside Hospital, Glen Oaks, NY 11004, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4002-3552","authenticated-orcid":false,"given":"Tobias","family":"Hofmann","sequence":"additional","affiliation":[{"name":"Center for Internal Medicine and Dermatology, Department for Psychosomatic Medicine, Charit\u00e9-Universit\u00e4tsmedizin Berlin, Corporate Member of Freie Universit\u00e4t Berlin, Humboldt-Universit\u00e4t zu Berlin, and Berlin Institute of Health Berlin, 12200 Berlin, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andreas","family":"Stengel","sequence":"additional","affiliation":[{"name":"Center for Internal Medicine and Dermatology, Department for Psychosomatic Medicine, Charit\u00e9-Universit\u00e4tsmedizin Berlin, Corporate Member of Freie Universit\u00e4t Berlin, Humboldt-Universit\u00e4t zu Berlin, and Berlin Institute of Health Berlin, 12200 Berlin, Germany"},{"name":"Department of Psychosomatic Medicine and Psychotherapy, Medical University Hospital T\u00fcbingen, 72076 T\u00fcbingen, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Julia","family":"Grosser","sequence":"additional","affiliation":[{"name":"Department of Child and Adolescent Psychiatry, Charit\u00e9-Universit\u00e4tsmedizin Berlin, Corporate Member of Freie Universit\u00e4t Berlin, Humboldt-Universit\u00e4t zu Berlin, and Berlin Institute of Health, 13353 Berlin, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Verena","family":"Haas","sequence":"additional","affiliation":[{"name":"Department of Child and Adolescent Psychiatry, Charit\u00e9-Universit\u00e4tsmedizin Berlin, Corporate Member of Freie Universit\u00e4t Berlin, Humboldt-Universit\u00e4t zu Berlin, and Berlin Institute of Health, 13353 Berlin, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2020,3,7]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Association, American Psychiatric (2013).
