Objective To study prevalence of obstructive sleep apnea-hypopnea syndrome(OSAHS) of preschool children in Liwan district and provide basis for further interventions. Methods Four kindergartens were selected randomly from two streets in Liwan District, Guangzhou city.The body height and weight of all the children in the four kindergartens were measured, a cross-sectional survey was carried out among their parents.Children who snored habitually were identified.All habitual snoring children were invited to undergo polysomnography (PSG) evaluation. Results There were 1 326 children in this survey.Among them, 259 were habitual snorers.The prevalence rate of habitual snoring was 19.53%.According to the PSG results, 96 children with OSAHS were identified.The prevalence rate of OSAHS was 7.24%.The OSAHS prevalence rates were not significant different between boys and girls.Multiple conditional logistic regression analysis showed that habitual snoring in father, incidence number of tonsillitis and rhinitis and Height standard body weight were the risk factors associated with OSAHS in children. Conclusions The prevalence rate of preschool children OSAHS is high in Guangzhou Liwan District, there are many independent risk factors associated with OSAHS in preschool children.Comprehensive intervention measures should be carried out.
