Objective To explore the effect of differentaltitude on sleep apnea-hypopnea of Han Nationality and Uyghur Nationality.Methods 288 subjects were underwent respiration and pulse oximeter tests.Apnea-hypopnea index(AHI),hypopnea index(Hl),mean SaO_2(MSaO_2%),the lowest SaO_2(LSaO_2%),the time spent at SaO_2 below 90%,the number of desaturations≥4%per hour(ODI_4)were calculated at different altitude district(Keramay city altitude 500 m and Kunming city altitude1890m).Include 114 cases of SAHS from Keramay city and 174 cases of SAHS from Kunming city.select 42 cases SAHS of Han nationlity and 22 cases SAHS of Uyghur nationlity from Keramay city.the two groups were matched for age,sex.Results The body mass[(27.1±4.l) kg/m~2vs.(29.6±4.5) kg/m~2]、 neck circumference[(39.0±3.5) cm vs.(41.0±2.9) cm],abdominal circumference[(87.1±9.5) cm vs.(98.0±11.6) cm]、 oxygen desaturation index[(32.3±21.5) /h vs.(51.1±29.4) /h]、 the mean arterial oxygen saturation[(87.2±7.8)%vs.(90.5±4.1)%]、 the nadir arterial oxygen saturation[(72.9±11.7)%vs.(82.7±7.4)%]、 apnea index[(49.2±28.5) /h vs.(33.1±21.5) /h]、 The Arterial oxygen partial pressure(PaO_2)[(63.2±10.6) mmHg vs.(80.9±13.4) mmHg]and Arterial carbon dioxide partial pressure(PaCO_2)[(33.3±5.6) mmHg vs.(41.4±3.7) mmHg]were significant difference bettween Kunming and Keramay's SAHS groups(P<0.01).The PaO_2[(63.2±10.6) mmHg vs.(80.9±13.4) mmHg]and PaCO_2[(33.3±5.6) mmHg vs.(41.4±3.7) mmHg]were significant difference bettween Han Nationality and Uyghur Nationality SAHS groups(P<0.01).Conclusions Sleep disorder breathing were related to different altitude and nationality,the high altitude may induce the PaO_2 and PaCO_2 of OSAHS during the daytime,This is may be attribute to the function of respiratory control.
