| Objective To investigate the prevalence of obstructive sleep apnea hypopnea syndrome (OSAHS) among children aged 6 to 12 years old in Yibin, as well as the characteristics and quality of life (QOL), so as to provide guideline for OSAHS prevention, treatment and health education.Methods From January to June 2018, 1903 children aged 6 to12 years old were selected randomly by stratified cluster sampling from Yibin, with OSAHS preliminary screening by Berlin questionnaire, then 94 positive children were recruited into OSAHS group and 1 825 normal children into non-OSAHS group. OSAHS group after preliminary screening was definitely diagnosed by polysomnography (PSG) and subdivided into normal group (51 cases) and overweight/obesity group (43 cases) for the assessment of quality of life by OSA-18, and the difference in PSG monitoring index and quality of life was also detected.Results There were 94 suspicious positive OSAHS children screened by Berlin questionnaire with the prevalence of 4.94%, and the prevalence in male was higher than that in female (χ2=5.50, P=0.02); 78 children were definitely diagnosed as OSAHS by PSG with the prevalence of 4.10%. The apnea index, hypopnea index, apnea-hypopnea index and obstructive apnea index in overweight/obesity group were higher than those in normal group, and the mean oxygen saturation and lowest oxygen saturation were lower than those of normal group, and the difference was statistically significant (P<0.05). The body mass index, neck circumference, systolic pressure and diastolic pressure in OSAHS children were higher than those in non-OSAHS children, and the difference was statistically significant (P<0.05). The total OSA-18 score and 3 dimensions, including sleep, emotion and daytime in overweight/obesity group were higher than those in normal group, and the difference was statistically significant (P<0.05).Conclusions The prevalence of OSAHS is approximately 4.10% among children aged 6 to 12 years old in the city of Yibin, and the PSG and QOL indexes of overweight/obesity children is inferior to those of normal children, which calls for health education and behavioral intervention. |
