Commonly, the clinicians only attribute it to the age. This study aims to elucidate the distribution characteristics and major factors associated with CA in pediatric OSA.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>A retrospective chart review of PSG data of children with OSA from January 2017 to March 2018 was performed.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>856 children (317 girls and 539 boys, 4.9 \u00b1 2.4 years) were involved. 50.1% (429\/856) had a CAI &amp;gt; 1, and 2.9% (25\/856) had a CAI &amp;gt;5. Children with a CAI &amp;gt;1 had a higher OAHI, arousal index (AI), oxygen desaturation index (ODI), and a longer REM period, but a younger age and a shorter slow-wave sleep (SWS) phase. Multivariate binary logistic regression showed that with a 1% increased REM period, the risk of the CAI being &amp;gt;1 increased by 5.3% (<jats:italic>p<\/jats:italic> &amp;lt; 0.001). The CAI increased with an increasing OAHI (<jats:italic>p<\/jats:italic> = 0.003).
