We determined the velocity (slope of change) of yearly weight gain using a mixed effect linear regression model. Subsequently, we determined if velocity of yearly weight gain was greater in adolescents with severe OSA (apnea\u2010hypopnea index\u2009&gt;\u200910).

The velocity of yearly weight gain prior to PSG in Down syndrome adolescents was similar regardless of OSA severity (mean diff in weight gain at PSG between severe and nonsevere OSA\u00a0=\u00a0\u22121.42, 95% confidence interval\u00a0=\u00a0\u22125.8 to 2.9,\n                      <jats:italic>P<\/jats:italic>\n                      \u00a0=\u2009.52).
