重庆地区男男性行为人群多性伴行为特征及影响因素

目的  了解重庆地区艾滋病病毒(human immunodeficiency virus, HIV)阴性多性伴肛交(≥5人)男男性行为者(men who have sex with men, MSM)的人口学和性行为特征及其影响因素。 方法  从2018年6月至2019年6月, 招募重庆地区319名HIV阴性MSM, 收集其人口学特征、近半年内安全套使用率、是否感染性病、性角色、药物滥用史、是否服用过暴露后预防(post-exposure prophylaxis, PEP)药物、是否关注HIV知识和是否服用过暴露前预防(pre-exposure prophylaxis, PrEP)药物等信息。采用单因素和多因素Logistic回归分析模型分析MSM人群多性伴肛交的影响因素。 结果  319名HIV阴性MSM中, 34.5%(110/319)近6个月内性伴人数≥5人; 110名多性伴MSM中, 63.6%(70/110)年龄≤28岁, 75.4%(83/110)学历为大学本科或大专; 50名报告情感状况的MSM中, 72.0%(36/50)为单身。多因素Logistic回归分析模型分析显示, 服用过PEP药物和经常关注HIV知识是MSM多性伴肛交的主要影响因素。 结论  重庆地区HIV阴性MSM人群普遍存在多性伴肛交现象。应加大对MSM人群, 尤其是低龄MSM人群, HIV防治知识的宣教力度。在推广PrEP和PEP在MSM人群中的使用时, 应警惕其相关风险补偿。     

Changes of human immunodeficiency virus (HIV) burden globally and in China over three decades: a secondary analysis of global HIV statistics

Background:A more comprehensive understanding of the trends of incidence, prevalence, and mortality in human immunodeficiency virus (HIV), and their complex interrelationships, may provide important evidence for decision-making related to HIV prevention and control. The variances in these indices between different population groups, genders, and ages are critical to decipher evolving patterns of the HIV epidemic in specific populations.Methods:A secondary analysis of relevant data was conducted using data extracted from the Global Burden of Disease study of 2019. HIV/acquired immune deficiency syndrome (AIDS) incidence, prevalence, AIDS-related mortality, and mortality-to-prevalence ratio (MPR) for annual percentage change, average annual percentage change (AAPC), and corresponding 95% confidence intervals (CIs) were calculated using joinpoint regression statistical analysis.Results:The AAPC of HIV/AIDS incidence, prevalence, AIDS-related mortality rate, and MPR were –1.4 (95% CI: –1.6, –1.2), 4.1 (95% CI: 4.0, 4.3), 2.0 (95% CI: 1.7, 2.3), and –2.1 (95% CI: –2.3, –1.8) between 1990 and 2019 globally, and were 3.5 (95% CI: 2.2, 4.8), 6.9 (95% CI: 6.8, 7.0), 8.1 (95% CI: 7.1, 9.1), and 1.2 (95% CI: 0.1, 2.3) in China during the same period. In terms of differences in the preceding indicators by gender, we observed a similar pattern of trends for male and female genders both globally and in China during the entire study period. Each specific age group exhibits a distinct pattern in terms of incidence, prevalence, mortality rate, and MPR both globally and in China.Conclusions:Prevalence and mortality rates of HIV/AIDS have increased between 1990 and 2019 globally and in China. While the incidence rate and MPR have declined globally over the past three decades, these two indicators are observed to present an increasing trend in China. There is a high HIV burden among young and middle-aged adults globally; however, the elderly have a high HIV burden in China. HIV screening at older age should be scaled up, and patients with advanced HIV disease should be provided early with additional care and health resources.

抑郁性神经症和重性抑郁症的临床特征差异比较分析

目的：比较抑郁性神经症（ND）和重性抑郁症（MD）的临床特征的差异。方法：对符合CCMD－2－R诊断标准的30例ND和32例MD进行 对照分析。结果：两组患者在起病年龄、发病诱因、内向性格、阳性家族史、用药及转归方面均无显著性差异，在临床症状上的差异也仅表现在严重程度上。结论：ND具有心境障碍的性质。作者认为ND的分类学位置值得重新考虑。
