Objective: To more ESS sleepiness score with night polysomnography related research, to further clarify the prevalence of OSAHS Ningxia people over the age of 20, to provide baseline information for the prevention and control of the region of OSAHS. Methods: According to the crowd OSAS the Ningxia region for more than 20 years old in June 2007 to December 2008 epidemiological survey sample, take random stratified cluster sampling method, as the standard ESS sleepiness score of 1534 cases, patients with severe snoring in accordance ESS ≥ 3, ESS ≥ 6 and ESS ≥ 9 points from four regions randomly 20 cases of this stage of the study, a total of 255 cases, its general inquiry ESS sleepiness score review, measurement of height, weight, neck circumference and all night portable polysomnography, the resulting data entered into the computer, SPSS16.0 software for statistical analysis. Measurement data with x ± s, comparison between groups using chi-square test, rank correlation analysis and comparison of ESS and AHI and SaO2 relationship AHI ≥ 5 / h as the gold standard of diagnosis of OSAHS draw the receiver operating characteristic curve (ROC curve), the area under the ROC curve 0.7-0.9 with a moderate degree of diagnostic accuracy; cross-mapping method to determine the optimum operating point, and at the same time maximize the sensitivity and specificity. Results: In this study, the effective questionnaire to 251 men, 177 cases (70.52%) and 74 females (29.48%); of Han 131 cases (52.20%), Hui 120 cases (47.80%); urban residents, 127 cases (50.60%), rural residents in 124 cases (49.40%). Which the snoring group of 73 cases, 127 cases of mild OSAHS group, moderate OSAHS group of 21 cases, severe OSAHS group 30 cases, snoring group with OSAHS group in neck circumference, BMI there are obvious differences, ESS sleepiness score and AHI was positive correlation was negatively correlated with nocturnal oxygen saturation, ESS the sleepiness score table of OSAHS with a diagnosis of moderate value, when the ESS = 7.5 highest sensitivity and specificity, AHI ≥ 5 / h timeshare combine the day between sleepiness ESS ≥ 9 is divided into diagnostic criteria, further draw OSAHS Ningxia people over the age of 20, the prevalence was 3.41%, including 5.00% prevalence rate for male and female prevalence was 1.25%, the male prevalence significantly higher than women; Han prevalence rate of 2.80%, 3.68% Hui was no difference between the two ethnic prevalence; urban residents in the prevalence rate of 3.95%, 2.04% in rural areas, the urban prevalence was significantly higher than in rural areas, prevalence above results are similar to the results of the first stage of screening. Surveyed 251 patients, 46.22% of respondents believe that snoring is not a disease; 35.06% of respondents believe that snoring is a disease, but do not require treatment; 18.72% of the respondents believe that snoring is sick and needs treatment. Conclusion: 1, snoring group with OSAHS group is present in the body mass index, neck circumference greater difference in performance for OSAHS group was significantly higher than the snoring group. ESS sleepiness score with PSG correlation ESS sleepiness score was a significant positive correlation with AHI was significantly negatively correlated with nocturnal SaO2. 3, ESS sleepiness score sheet with a moderate diagnostic value of OSAHS can be applied to the the primary hospital OSAHS screening and condition assessment. 4, the stage after PSG monitoring results show AHI ≥ 5 / h combined with daytime sleepiness ESS ≥ divided into diagnostic criteria, Ningxia people over the age of 20 OSAHS prevalence rate of 3.41% male prevalence was 5.00 %, female prevalence rate was 1.25%, the male prevalence was significantly higher than that of women; Han prevalence was 2.80%, 3.68% Hui was no difference between the two ethnic prevalence; prevalence was 3.95% for urban residents, 2.04% in rural areas, the urban prevalence was significantly higher than in rural areas, prevalence above results are similar to the results of the first stage of screening. 5, the residents of our region's general lack of awareness of snoring and OSAHS.
