Objective:To investigate and study the prevalence of sleep-disordered breathing related symptom of school children in Jinan district.Obstructive sleep apnea-hypopnea syndrome is the most important one of SDB,and its influence to children is very big.The mobidity of SDB is vary in different district’s reports.It can be expected to provide the epidemiologic data of Jinan district by this survey and make some contribution to know this disease well by parents and society.Methods:Children aged 7 to 12 from 4 schools of Jinan district were selected by random and investigated by giving modified Tucson Children’s Assessment of Sleep Apnea questionnaire to their parents during October 2006 to September 2007.All children must have no infected or neuroendocrine or cardiovascular disease in last one month.The intent of questionnaire include body height and weight,sleep snore, apnea,mouth breathing,mouth waterless in the morning,abnormal sleep position, limb twitch,moring headache,troubled by tonsillitis or tonsillar hypertrophy,bad study achievement,poor attention concentration,too much behavior and so on.Analyze the incidence rate of sleep-disordered breathing related symptom of these children, discrepancy of different gender in sleep-disordered breathing related symptom,the relevant dangerous factors of sleep snore and apnea by SPSS 10.0.,and imply the PSG to the children that suspected having SDB. Results:1.The incidence rate of sleep-disordered breathing related symptom of those SDB children:in this 1596 aged from 7 to 12 investigated children,there are 782 male and 814 female children.Male:female=0.96:1,average age is 9.5.The number of children that never snore is 762,occupying 47.7%of all children;occasionally snore 1 or 2 nights per month is 488,occupying 30.6%;snore 1 or 2 nights per week is 282,occupying 17.7%;snore every night is 64,occupying 4%.Apnea is observed in 31 children,occupying 1.9%.Other incidence rate is bed-wetting 4.6%,abnormal sleep position 18.5%,mouth breathing 11.7%,limb twitch 14.8%,morning headache 1.9%,mouth waterless in the morning 16.4%,poor attention concentration 13.9%,too much behavior 12.2%,bad study achievement 6.5%.2.There is some gender discrepancy in sleep-disordered breathing related symptom of those SDB children.There are more male children than female children in sleep snore,apnea,bed-wetting,abnormal sleep position,mouth breathing,mouth waterless in morning,too much behavior,poor attention concentration,bad study achievement.And this discrepancy has statistical significance.But there is no conspicuous discrepancy in limb twitch and headache in the morning.The results as follows:sleep snore(x~2=5.5970,P=0.0180),apnea(x~2=4.4449,P=0.0350), bed-wetting(x~2=14.0518,P=0.0002),abnormal sleep position(x~2=13.9268, P=0.0002),mouth breathing(x~2=12.7311,P=0.0004),mouth waterless in morning (x~2=18.2774,P=0.0000),poor attention concentration(x~2=17.8835,P=0.0000),too much behavior(x~2=13.7857,P=0.0002),bad study achievement(x~2=11.9547, P=0.0005).3.The relevant dangerous factors of snore include bad nose respiration (P=0.0013,OR=4.17),male gender(P=0.0042,OR=1.62),father snore(P=0.0021, OR=2.05),mother snore(P=0.0029,OR=2.01),both snore(P=0.0019,OR=3.35). The relevant dangerous factors of apnea include snore(P=0.0010,OR=4.31),bad nose respiration(P=0.0331,OR=2.26)and tonsillitis(P=00419,OR=1.97).4.There are 109 male SDB children’s BMI smaller than normal children,65 male SDB children’s BMI equal to normal children,and 15 children larger than normal children.In the female SDB children,there are 107 children’s BMI smaller than normal children,32 children equal to normal children,and 18 children larger than normal children.There are 216 children those BMI smaller than normal children in all,but the total number of children those BMI equal to and larger than normal children is 130.5.Giving PSG to 30 children that suspected having SDB,there are 16 children diagnosed OSAHS and 14 children diagnosed PS.These OSAHS children have more NREMⅠandⅡsleep but less NREMⅢ+Ⅳand REM sleep contrast to nomal children.6.This survey shows us that there are 312 children’s parents alive to their children have sleep problem but have no inspect to the hospital.These parents occupy 37.4%of all children’s parents.470 children’s parents do not know their children have sleep problem,they occupying 56.4%.There are only 12 children’s parents take their children to exam in the hospital and 14 children’s parents treat their children, occupying 1.4%and 1.7%respectively.Conclusions:1.The ratio of snore is lower than Wuxi,Wenzhou,Nanjing and HangKong’s data.The ratio of apnea is higher than those four city’s data.2.There is some gender discrepancy in sleep-disordered breathing related symtom of those SDB children,such as sleep snore,apnea,bed-wetting,abnormal sleep position,mouth breathing,mouth waterless in morning,too much behavior,poor attention concentration and bad study achievement.3.There are 5 relevant dangerous factors of snore.They are bad nose respiration, male gender,father snore,mother snore and both parents snore.There are 3 relevant dangerous factors of apnea.They are snore,bad nose respiration and tonsillitis.4.The subtotal SDB children have small BMI than normal children.5.OSAHS children have more NREMⅠandⅡsleep but less NREMⅢ+Ⅳand REM sleep contrast to nomal children.6.The parents have no sufficient understanding and to think highly of this disease.
