Objective MSAR ninth grader sleep quality, sleep mode and its influencing factors. Methods A randomized overall sampling extraction Macau 535 junior high school students in grades three to survey research methods, including homemade General Status Scale, Scale Pittsburgh Sleep Quality Index (PSQI), State - Trait Anxiety Inventory (STAI ), Beck Depression Inventory (BDI), Adolescent Life Event Scale (ASLEC), Epstein Wo Sisi Sleepiness Scale (ESS), the morning-and evening-type scale (MEQ), and fill in the total last exam Average score for the grade. Through the school teacher responsible for each class distributed to other students to fill out, personally supervised by the investigator to recover the questionnaire in the collation and input data, using SPSS13.0 t-test, analysis of variance, chi-square test, correlation analysis and multiple linear Regression analysis was detected. Results 1 in 535 questionnaires, after screening questionnaire found damaged or did not fill the entire total of 34 questionnaires that were 501 valid questionnaires. 2 In the 501 students interviewed, the boys have 258 people (51.5%), there are 242 girls (48.5%), aged 12-19 years (15.38 ± 1.328). 3 respondents weekday bedtime is 22:30, wake up time is 7:00 am, the average total sleep time was 457 ± 75 minutes, but on weekends and holidays than usual bedtime and wake time were delayed by three to four hours (time is 2:00 to go to bed, wake up in the morning 10:30 to 11:00), the average total sleep time was also significantly extended to more than 600 minutes. 4.PSQI score and ESS score girls than boys (PSQI male vs female: 4.81 ± 2.63 vs 5.52 ± 2.46, P value of 0.002; ESS male vs female: 7.95 ± 4.79 vs8.86 ± 4.57, P = .03), weekdays Average total sleep time shorter girls than boys (male vs female: 472 ± 85 分钟 vs442 ± 59 分钟, P lt; 0.001), while the overall average during weekends and holidays sleep time, girls significantly longer than boys (male vs female weekend : 590 ± 97 vs 628 ± 110 分钟 分钟, P lt; 0.001; holidays male vs female: 581 ± 103 分钟 vs631 ± 109 分钟, P lt; 0.001). 5 MEQ score of the students surveyed 13.34 ± 3.09, where girls score lower than boys (male vs female: 13.71 ± 3.17 vs12.84 ± 2.95, P value 0.005). 6, 25.2% of the students perceived sleep problems, including watching television or using the computer longer (PSQI: P value of 0.016, ESS: P value of 0.002), the heavier the pressure of study (PSQI and ESS: P lt; 0.001) as well as those who have no interest in learning more (PSQI and ESS: P lt; 0.001), worse sleep quality, daytime somnolence also more prone; addition, drinking habits, bedroom environment noisy, poor relationship with his family, as well as the relationship between the parents that students with poor sleep quality is also relatively poor. 7 In the detection of psychological conditions, the respondents average score of students in BDI 13.48 ± 10.34, STAI average score of 78.87 ± 17.04, and negative life events in the detection, ASLEC average score was 37.11 ± 10.34. 8. By Students visit the most recent examination focused on the overall average scores are between 61-80 minutes, while the poorer quality of sleep and Bai Tiansi sleep the more serious students, their scores are at their highest and the lowest two extremes. 9 In the correlation analysis results show, PSQI respectively ESS, BDI, TAI, ASLEC six factors were positively correlated with MEQ, weekday total sleep time and achievement levels (ie, the last representative of the total average score of the class: 1 -91 to 100 2-81-90 minutes 71-80 minutes 3-5 4-20 61-70 points, 5 a lt; 60 points) were negatively correlated. 10 linear correlation and regression analysis suggested that, ASLEC fifth factor, MEQ, BDI, gender PSQI and ESS are likely to be a risk factor; ASLEC fourth, fifth and sixth factor, MEQ, PSQI and ESS TAI may be risk factors; MEQ, PSQI, gender, and overall TAI weekday sleep time may be a risk factor. 11 According to the PSQI and ESS scores were divided, with 16.4% and 13.6% of the students be classified as poor sleep quality (PSQI ≥ 8 points) and Bai Tiansi sleepers (ESS gt; 14), they usually sleep patterns more tend to be nocturnal type (MEQ sleep quality is relatively good vs poor quality of sleep: 13.61 ± 2.96 vs11.99 ± 3.19, P lt; 0.001; without Baitian Si vs Baitian Si sleep sleep: 13.54 ± 3.01 vs11.97 ± 3.23, P lt; 0.001) The average total sleep time was shorter (sleep quality is relatively good vs poor sleep quality: 466 ± 76 分钟 vs419 ± 82 分钟, P lt; 0.001; without Baitian Si vs Baitian Si sleep sleep: 461 ± 75 分钟 vs438 ± 71 min, P lt; 0.02), while the BDI score and ASLEC is also relatively high (BDI sleep quality is relatively good vs poor quality of sleep: 12.28 ± 9.43 vs19.64 ± 11.95, P lt; 0.001; without Baitian Si vs Baitian Si sleep sleep : 12.79 ± 9.95 vs17.9 ± 11.69, P lt; 0.001; ASLEC sleep quality is relatively good vs poor quality of sleep: 34.87 ± 22 vs48.4 ± 27.75, P lt; 0.001; without Baitian Si vs Baitian Si sleep sleep: 35.73 ± 22.97 vs 45.85 ± 28.42, P 0.001), in a recent examination of the total average score is relatively low. Conclusions 1. Poor quality of sleep, Bai Tiansi sleep in Macau ninth grader is more common, the respondents in the whole school day, the average sleep less than eight hours, but you do not need to extend the school day to supplement the sleep time, and this kinds of situations in the girls more significant. (2) most students still living environment, is the main factor affecting sleep study pressure, interest in learning, as well as watching television or using the computer for too long. 3 Most students all have mild depressive state of mind, and their psychological conditions (depression and anxiety) how to cope with negative life events were associated with sleep quality and sleep Baitian Si are closely related, and the poor quality of sleep Bai Tiansi sleeping students who have poor psychological state, vulnerable to negative life events. 4 Although the poorer quality of sleep can be seen and sleep the more serious students Baitian Si, their most recent test scores in the highest overall average and the lowest of the two extremes, but further define the poor quality of sleep and sleep Baitian Si student, then They can be found in the most recent test scores at a low level overall average.
