Objective To investigate the mental health status, perceived social support, as well as the relationship between them among middle school students in Wenchuan Earthquake region, so as to provide references for the relevant department to formulate appropriate strategies and intervention measures. Methods A cluster sampling method was adopted to select all 1698 students (excluded the students in Grade 3) as the research subjects from three middle schools in the disaster regions. All students were investigated with self-designed basic information questionnaire, Symptom CheckList 90 (SCL-90) and Perceived Social Support Scale (PSSS) through self-administered questionnaire. Results The overall positive rate on the SCL-90 was 46.3% among 1690 students, of whom 66.6% had mild psychological problems and 26.5% had moderate to severe psychological problems. The positive rate on the SCL-90 and the score for each factor of SCL-90 were statistically higher in the female students than male students (Plt;0.05). Compared with the senior middle school students, the score on the phobic anxiety subscale of the SCL-90 was statistically higher in the junior middle school students (Plt;0.05), while the score on the obsessive-compulsive subscale was otherwise statistically lower (Plt;0.05). With the exception of the hostility subscale, the score on each subscale of the SCL-90 in the urban students was statistically lower than the rural students (Plt;0.05). The median score on the perceived social support subscale was 60.00, with significant differences between the students of different sexes and grades (Plt;0.05). The overall score on the perceived social support subscale was negatively correlated with the SCL-90 score (r= –0.261, Plt;0.05). The score was negatively correlated with the SCL-90 score in the students regarding different sexes, grades and living areas prior to the earthquake (Plt;0.05). Conclusion The middle school students in the disaster regions have prominent psychological problems; perceived social support is helpful to promote the development of their mental health. In conducting psychological intervention, the difference of individuals’ mental health among different student groups should be concerned, so as to carry out targeted counseling and education.
Objective To learn the impact of health education on schistosomiasis among high school students in Wanzhou area of Three Gorges Reservoir, and to evaluate its effects. Methods The stratified multi-level cluster randomized sampling was used to survey 566 high school students in Wanzhou and Yunyang areas, and the questionnaire was used to investigate their recognition of schistosomiasis. Results After one-year health education on schistosomiasis, the passing rate of the knowledge about schistosomiasis prevention among high school students in demonstration area raised from 9.43% to 98.87% (χ2=463.46, P=0.000), which was higher than that of the inside and outside control areas (χ2=312.92, P=0.000); the passing rate of the attitude and belief of schistosomiasis prevention were 98.12%, which was higher than that of the inside and outside control areas (χ2=109.49, P=0.000); 56.02% of high school students in demonstration area had no susceptible behavior of schistosomiasis, which was higher than that of the inside and outside control areas (χ2=237.53, P=0.000). Conclusion Health education on schistosomiasis can efficiently improve the awareness of schistosomiasis prevention among high school students, and has important meanings for controlling potential epidemics and spread of schistosomiasis in Wanzhou area of Three Gorges Reservoir.
目的 调查汶川地震灾区中学生肠易激综合征（IBS）的患病情况，分析罗马Ⅱ和罗马Ⅲ诊断标准对该人群IBS患病率的影响。 方法 在汶川地震后2年半和3年，分别用罗马Ⅱ和罗马Ⅲ标准制定IBS中学生问卷调查表对地震灾区和非地震灾区5所中学的中学生进行2次调查，分析比较IBS患病率的变化。 结果 用罗马Ⅱ标准调查发现地震灾区中学生IBS患病率为23.6%；非地震灾区患病率为21.6%，二者比较无统计学意义（P=0.267）；用罗马Ⅲ标准调查发现地震灾区中学生IBS患病率为6.2%，非地震灾区患病率为4.6%，二者比较无统计学意义（P=0.139）。符合两种诊断标准的地震灾区IBS学生有10.3%，非地震灾区IBS学生有9.2%，两者差异无统计学意义（P＞0.05）。②支持两种诊断标准的症状方面，地震灾区IBS学生每天排便＞3次或每周排便＜3次等症状相比较有统计学意义（P＜0.001）。③按罗马Ⅲ标准，各亚型构成比IBS-C为30.4%，IBS-D为28.4%，IBS-M为8.8%，IBS-U为32.4%；按罗马Ⅱ标准，各亚型构成比为IBS-C为28.5%，IBS-D为47.7%，腹泻和便秘交替型为18.6%，罗马Ⅲ标准中的IBS-M和IBS-U合为一组与罗马Ⅱ标准中的腹泻和便秘交替型的构成比进行比较，二者有统计学意义（P＜0.001）。 结论 罗马Ⅱ和罗马Ⅲ两种标准调查地震灾区中学生IBS患病率和分型存在着差异，但两种标准对地震灾区IBS患病率的影响是对等的，患病率和分型的不同是由两种标准的本身的差异造成，可能更接近罗马Ⅲ诊断标准。
Objective To investigate the AIDS knowledge and sexual behavior of middle school students in the key areas of HIV/AIDS epidemic in Liangshan, Sichuan Province in 2015 and 2020, so as to understand the epidemic trend and acquire possible references for future prevention. Methods A survey on AIDS knowledge and sexual behavior of middle school students was conducted in 2015 and 2020 in the key areas of HIV/AIDS epidemic in Liangshan, Sichuan Province, respectively. The prevalences of HIV/AIDS knowledge and sexual behavior were analyzed. Results The rate of AIDS education was increasing, which was 75.4% in 2015 and 89.3% in 2020, respectively. However, the awareness rate of AIDS remained low, which was 44.4% in 2015 and 53.3% in 2020, respectively. The reported rate of sexual behavior decreased, which was 12.8% in 2015 and 1.6% in 2020, respectively. The condom usage rates were still low, with 47.4% and 55.8%, respectively in 2015 and 2020. Conclusions The AIDS publicity and education work in Liangshan is effective, and the awareness rate of AIDS, the rate of sexual behavior and the usage rate of condom are improving well. However, the slow increase in the awareness rate of AIDS and the usage rate of condom require further in-depth analysis aiming at the specification of this area so that effective scientific measures can be carried out to prevent the HIV/AIDS diffusion.
