[Differential evaluation of diagnostic criteria for pediatric obstructive sleep apnea hypopnea syndrome].

To evaluate the difference of accessing pediatric sleep symptoms and living qualities between 3 diagnostic criteria: American Thoracic Society (ATS), International Classification of Sleep Disorder (ICSD-3), domestic Urumqi criterion (Draft); To investigate the relationship of PSG parameters and quality of life scale OSA-18. Children with snoring who received PSG in Capital Medical University Beijing Tongren Hospital were recruited from Jan 2016 to Apr 2017. Subjects were diagnosed and grouped to SS, ICSD, ATS&ICSD (ATS&ICSD1, ATS&ICSD2) according to 3 criteria: ATS (AHI>5 or OAI>1), ICSD-3 (OAHI≥1) and Urumqi (AHI>5 or OAI>1, with LSaO₂<92%). Subjects' height, weight as well as quality of life scale OSA-18 were recorded. Five hundred and fifteen children were finally included (Male: 350 cases, Female: 165 cases). There were 315, 70 and 130 children in group SS, ICSD, ATS&ICSD respectively. Weights and BMI of ICSD and ATS&ICSD were significantly higher than those of SS (<0.05), and dysplasia scale of ATS&ICSD was higher than SS (<0.05); after adjusting height, weight and BMI, sub-scores of sleep disorder were statistically different between 3 groups (<0.05). Numbers and indexes of respiratory events other than central apneas and hypopneas in group SS, ICSD and ATS&ICSD were increased sequentially and statistically different (<0.05); numbers and indexes of respiratory events other than mixed apneas in ATS&ICSD2 were significantly higher than that of ATS&ICSD1 (<0.05). OAHI≥1/h combined with LSaO₂<92% should be used as pediatric OSAHS diagnostic criterion.
