目的:运用meta分析了解我国自愿咨询检测门诊HIV检测的阳性率,为提高艾滋病自愿咨询检测服务的覆盖面和有效性提供参考意见。方法:系统检索2013年1月1日—2024年1月23日中国知网、万方数据知识服务平台、维普数据库、PubMed、Web of Science、Embase中关于自愿咨询检测门诊HIV检测筛查的文献。采用随机效应模型对提取的数据进行meta分析,采用meta回归及亚组分析识别可能的异质性来源。结果:共筛选出59篇文献,其中中文文献58篇,英文文献1篇。HIV总检测例数为777186例,检出阳性19329例。meta随机效应模型显示,HIV合并阳性率为5.18%(95%CI为3.62%~7.42%,I^(2)=99.8%),因商业异性性行为而进行咨询检测的人群合并阳性率为2.66%(95%CI为1.64%~4.31%,I^(2)=99.4%),因非商业异性性行为而进行咨询检测的人群合并阳性率为2.73%(95%CI为1.71%~4.36%,I^(2)=99.3%),因男男性行为而进行咨询检测的人群合并阳性率为15.37%(95%CI为12.86%~18.38%,I^(2)=99.8%)。亚组分析和meta回归分析结果显示,接受检测人群中男性人员比例可能是不同研究间的异质性来源。结论:我国自愿咨询检测门诊确诊的HIV阳性率较高,但由于各研究中数据来源的可靠性及样本量差异等因素导致研究间存在较高的异质性。我国仍需扩大检测以发现更多的HIV潜在感染者。

Objective To analyze the influencing factors on the occurrence of anxiety and depression among secondary school students in Shanxi Province in 2023 based on the random forest algorithm and to construct a prediction model to provide a scientific basis for preventing and controlling the occurrence of negative emotions such as anxiety and depression among secondary school students. Methods In September 2023, 104 826 secondary school students in 11 cities of Shanxi Province were selected by stratified random whole-cluster sampling method for questionnaire survey, and the Generalized Anxiety Scale(GAD-7) and the Center for Streamlined Depression Scale(CES-D) were used to investigate anxiety and depression. Epidata was used for database establishment, chi-square test was used for between-group comparisons, logistic regression was used for influencing factor analysis, and Python 3.7 was used to establish a random forest prediction model and rank the importance of each variable. Results The detection rates of anxiety and depression among secondary school students in Shanxi Province in 2023 were 33.26% and 23.72%, respectively, and were higher for girls than for boys, and higher for students in general and vocational high schools than for junior high school students. The results of multifactorial regression analysis showed that female students(OR: 1.846、1.655,95%CI: 1.794-1.901、1.602-1.710), high school(OR: 2.019、1.670,95%CI: 1.956-2.083、1.612-1.731), vocational high school(OR: 1.167、1.356,95%CI: 1.085-1.254、1.254-1.466), non-conventional family(OR: 1.105、1.248,95%CI: 1.072-1.140、1.206-1.292), living in school(OR: 1.102、1.117,95%CI: 1.070-1.136、1.080-1.155), eating fried food ≥1 time/day(OR: 1.296、1.375,95%CI: 1.227-1.369、1.297-1.457), being seriously injured(OR: 1.636、1.688,95%CI: 1.524-1.755、1.569-1.816), being bullied in school(OR: 2.315、3.411,95%CI: 2.150-2.492、3.165-3.677), being scolded by parents(OR: 2.881、3.191,95%CI: 2.766-3.001、3.059-3.328), smoking(OR: 1.344、1.435
