Abstract: Objective   To explore the characteristics and correlation of sleep disorders and attention deficit hyperactivity disorder in children with asthma. Methods   Thirtyfive children aged 6 to 14 with chronic duration of asthma were selected and divided into asthma basic control group and asthma noncontrol group according to the lung function and asthma control test (ACT) scores. The children's sleep disorder scale was scored and their nighttime sleep monitoring was performed. The integrated visual and auditory continuous performance test(IVACPT) and DasNaglieri cognitive assessment system (DN:CAS) were completed. Results  There were significant differences in the indicators of  Sleep Disturbances Scale for Children(SDSC) total score, disorders of initiating or maintaining sleep, sleepwake transition disorders and excessive sleep sweating between two groups (P<0.01). There were significant differences in the night sleep monitoring parameters between  two groups (P<0.05). Full scale response control quotient(FSCQ) and full scale attention quotient(FSAQ) in asthma noncontrol group detected by IVACPT were significantly lower than those in basic control group (P<0.01). Among the DN: CAS parameters, there were significant differences in planning ability(PLAN), simultaneous processing ability(SIM), attention ability(ATT), successive processing ability(SUC) and full cognition score(FS) of children between two groups(P<0.05). FSCQ and FSAQ in IVACPT parameters and PLAN, SIM, ATT, SUC and FS in DN: CAS parameters were negatively correlated with SDSC total score, disorders of initiating or maintaining sleep, sleepwake transition disorders and AHI  in the sleep parameters(all P<0.05), and positively correlated with sleep efficiency and lowest blood oxygen value (all P<0.05). Conclusion  Children with asthma are prone to sleep structure disorder and attention deficit hyperactivity disorder,  which are related to each other.
