Data collected in free anonymous HIV screening centers (Centre d'Information et de Dépistage Anonyme et Gratuit du VIH, CIdAG) are numerous but poorly exploited. The characteristics of the consultants, their risk factors and their behavior were rarely analyzed previously.
Data of 3995 patients attending the CIdAG of Colmar between January 93 and February 99 were prospectively analyzed. Two 18-month periods at the beginning and end of the study were compared.
The activity of the center was stable. Nine HIV infections were detected (2 p. 1000 consulting). The male/female ratio was 1.2 and the mean age was 26 years. The proportion of very young patients (<20 years) was 30 p. 100 and increased significantly between the two periods. Six per cent of the consultants were male homo/bisexuals and 2 p. 100 used intravenous drugs. A regular use of condoms when having occasional sexual relations was reported by 40 p. 100 of consultants before 20 years of age, but this proportion decreased regularly as the age increased. It was minimal among intravenous drug users (19 p. 100), and greater among male homo/bisexuals (46 p. 100) than among male heterosexuals (37 p. 100) and women (33 p. 100). This proportion increased significantly during the study period in heterosexual men and women but not in male homo/bisexuals. The number of sexual partners did not vary but the knowledge of the partners'status for HIV infection and drug addiction progressed significantly. Some subjects who attended the centre several times were identified anonymously. They differed from the other consultants by an older age (mean: 31), a higher proportion of male homo/bisexuals (14 p. 100) and a less regular use of condom (26 p. 100).
In some French anonymous HIV screening centers, information and prevention currently appears to prevail over detecting new HIV infections. Modifying at-risk behaviour is difficult. Current messages for prevention must be improved.
在免费匿名艾滋病毒筛查中心（科尔马艾滋病毒信息与免费匿名检测中心，CIdAG）收集的数据众多，但利用不足。此前很少分析咨询者的特征、他们的风险因素及行为。
对1993年1月至1999年2月期间在科尔马CIdAG就诊的3995例患者的数据进行前瞻性分析。比较了研究开始和结束时两个为期18个月的时间段。
该中心的活动稳定。检测到9例艾滋病毒感染（每1000名咨询者中有2例）。男女比例为1.2，平均年龄为26岁。非常年轻患者（<20岁）的比例为30%，且在两个时间段之间显著增加。6%的咨询者为男性同性恋/双性恋者，2%使用静脉注射毒品。20岁以下的咨询者中有40%报告在偶尔发生性行为时经常使用避孕套，但这一比例随着年龄增长而有规律地下降。在静脉注射毒品使用者中这一比例最低（19%），在男性同性恋/双性恋者中（46%）高于男性异性恋者（37%）和女性（33%）。在研究期间，异性恋男性和女性中的这一比例显著增加，但在男性同性恋/双性恋者中未增加。性伴侣数量没有变化，但对性伴侣艾滋病毒感染状况和吸毒成瘾情况的了解有显著进展。一些多次到该中心就诊的受试者被匿名识别。他们与其他咨询者的不同之处在于年龄较大（平均：31岁）、男性同性恋/双性恋者比例较高（14%）以及避孕套使用不太规律（26%）。
在一些法国匿名艾滋病毒筛查中心，目前信息和预防似乎比检测新的艾滋病毒感染更为重要。改变高危行为很困难。当前的预防信息必须改进。
