RESUMO

OBJECTIVES: To study the clinical features of obstructive sleep apnea (OSA) in children with obesity. METHODS: A retrospective analysis was performed on the medical data of 33 obese children aged 7-15 years, who were diagnosed with OSA and received polysomnography (PSG) in the Department of Respiratory Medicine in Shenzhen Children's Hospital. Fifty OSA children with normal body weight, matched for sex and age, were enrolled as the control group. RESULTS: Among the 33 obese children with OSA, the three most common daytime symptoms were inattention in 30 children (91%), somnolence in 22 children (67%), and morning fatigue in 21 children (64%), and the three most common nocturnal symptoms were snoring in 27 children (82%), mouth breathing in 20 children (61%), and sweating in 16 children (49%). Compared with the reference values of normal children, both the OSA + obesity group and the control group had prolonged light sleep, shortened deep sleep, and a significantly shortened rapid eye movement (REM) period, while there was no significant difference in these indices between the two groups (P>0.05). The apnea-hypopnea index, obstructive apnea/hypopnea index, and oxygen desaturation index in both REM and non-REM periods in the OSA +obesity group were significantly higher than those in the control group (P<0.05), while the lowest blood oxygen saturation during sleep was significantly lower in the OSA + obesity group (P<0.05). CONCLUSIONS: The children with obesity and OSA have the main daytime symptoms of inattention, somnolence, and morning fatigue and the main nocturnal symptoms of snoring, mouth breathing, and sweating. There is no significant difference in sleep structure between OSA children with obesity and those with normal body weight; however, respiratory events and blood oxygen saturation decline are more severe in OSA children with obesity.

RESUMO

OBJECTIVE: To study the clinical features of sleep-disordered breathing (SDB) in children with neuromuscular disease (NMD). METHODS: A retrospective analysis was performed on the medical data of 18 children who were diagnosed with NMD and underwent polysomnography (PSG) (NMD group). Eleven children without NMD who had abnormal sleeping habit and normal sleep structure on PSG were enrolled as the control group. The two groups were compared in terms of the daily and nocturnal symptoms of SDB, incidence rate of obstructive sleep apnea (OSA), pulmonary function, end-tidal partial pressure of carbon dioxide (PetCO2), features of sleep structure, and sleep respiratory events. RESULTS: In the NMD group, 16 children (89%) had related daily and nocturnal symptoms of SDB, and the youngest age was 1 year at the onset of such symptoms. Compared with the control group, the NMD group had significant reductions in total sleep time and sleep efficiency (P < 0.05), a significant reduction in the proportion of rapid eye movement (REM) sleep (P < 0.05), significant increases in obstructive apnea and hypopnea events (P < 0.05) and oxygen reduction events during REM sleep (P < 0.05), and a significant reduction in blood oxygen saturation during REM sleep (P < 0.05). In the NMD group, 17 children (94%) were diagnosed with OSA, and all children had normal lung function and PetCO2. CONCLUSIONS: There is a high proportion of children with SDB among the children with NMD, and SDB can be observed in the early stage of NMD, which results in the damage of sleep structure and the reduction in sleep efficiency. Respiratory events are mainly obstructive events, and oxygen reduction events are mainly observed during REM sleep.
