Analysis of the clinical characteristics in preschool and school-age chil-dren who snore
Objective To analyze the clinical and sleeping structure characteristics of preschool and school-age children who snore.Methods 285 children who snore admitted in our hospital from June 2020 to December 2021 were enrolled in this study.In addition,60 children who received a health examination in the children's health care department of our hospital were also included as controls during the same period.According to their age,these children were divided into the preschool-age group and the school-age group.Clinical data and polysomnography results were collected.Results The proportion of tonsil and/or adenoid hypertrophy was 88.9％,and the proportion of rhinitis/sinusitis was 31.5％in preschool-age children who snore,compared with 16.0％and 78.0％,respectively,in school-age children who snore.These differences were statistically significant(all P＜0.05).The proportion of open-mouth breathing was 75.3％,the proportion of laborious breathing was 35.7％,the proportion of apnea was 28.5％,and the proportion of nocturia was 55.3％in preschool-age children who snore,compared with 43.3％,10.0％,10.0％and 26.7％,respectively,in preschool-age children in the control group.These differences were statistically significant(all P＜0.05).The proportion of open-mouth breathing was 80.0％,the proportion of apnea was 24.0％,and the proportion of inattention was 68.0％in school-age children who snore,compared with 46.7％,6.7％and 43.3％,respectively,in school-age children in the con-trol group.These differences were statistically significant(all P＜0.05).The proportion of non-rapid eye movement 1(NREM1)stage,apnea-hypopnea index(AHI),oxygen desat-uration index(ODI),sleeping efficiency(SE),proportion of non-rapid eye movement 3(NREM3)stage and snoring in dex in preschool and school-age children who snore were statistically significantly different compared to these parameters in preschool and school-age children in the control group(all P＜0.05).The total sleep time and the proportion of NREM1 stage in preschool-age children who snore were statistically significantly different compared to these parameters in school-age chil-dren who snore(all P＜0.05).The snoring index was positively correlated with AHI,ODI and the proportion of NREM1 stage,and negatively correlated with the proportion of NREM3 stage in preschool-age children who snore(all P＜0.05).The snoring index was positively correlated with AHI,ODI and the proportion of NREM1 stage,and negatively correlated with the propor-tion of NREM3 stage and rapid eye movement(REM)stage in school-age children who snore(all P＜0.05).Conclusions The clinical manifestations and causes of snoring in preschool and school-aged children are different.Children who snore in different age groups have disordered sleeping structure.The changes in sleeping structure in school-age children who snore are more obvious than those in preschool children.The degree of snoring can be used as an important index to evaluate chil-dren with sleep disorders.
