Methods Refer to the Pittsburgh Sleep Quality Index (PSQI) scale and the disease specific quality of life for 1 813 children with obstructive sleep apnea 18 items survey (OSA-18),self-designed questionnaires were used to collect primary school students from 6 to 14 years old in Xi′an by the stratified random sampling method from February to June 2018.
