本研究运用描述流行病学方法,对1990—1994年间中国国际旅行者AIDS监测数据进行了分析。结果发现国际旅行是造成我国公民HIV感染的重要因素之一。经统计学检验,旅行归国人员的HIV感染率显著高于出国旅行人员(X~2=388.71;p<0.005),且出国旅行人员HIV感染率极低。在旅行归国人员中,各种原因的自费旅行归国人员感染率显著高于其它人群,而劳务归国人员感染率又显著高于海员(X~2=15.59;p<0.005)。按海员、公务归国人员、劳务归国人员、自费归国人员的顺序,HIV感染率依次增高。根据近年来各类归国人员HIV感染率的变化趋势,监测重点应为自费归国人员、劳务归国人员和公务归国人员。
In this study, epidemiological methods were used to describe the AIDS surveillance data of international travelers from 1990 to 1994 in China. As a result, it has been found that international travel is one of the important factors that contribute to HIV infection among our citizens. Statistically, the HIV infection rates among returnees were significantly higher than those traveling abroad (X ~ 2 = 388.71; p <0.005), and the HIV infection rates among traveling overseas travelers were extremely low. Among the returnees, the rates of return of self-financed returnees for various reasons were significantly higher than those of other groups, while the rates of infection among returnees were significantly higher than that of seafarers (X ~ 2 = 15.59; p <0.005). According to the order of seafarers, returned public servants, returnees, returnees at home and abroad, the HIV prevalence rates increased in turn. According to the trend of HIV infection among returnees in recent years, the focus of monitoring should be returned home-owned staff, returnees and returning civil servants.
