Using the cluster-sampling method, the authors estimated the seroprevalence of 4 sexually transmitted diseases (STDs) among the sexually active general population in a city of 30,000 inhabitants in the east of Gabon. The seroprevalences were 2% for HIV-1, 13.8% for hepatitis B, 8.6% for Treponema pallidum and 59.6% for Chlamydia trachomatis. The seroprevalences of hepatitis B and chlamydia were stable over time and similar to those registered in other countries of central Africa. On the other hand, the seroprevalence of T. pallidum is notably low in comparison with these countries and seems to be decreasing. The seroprevalence of HIV-1 is also low but has doubled in 8 years in the city. Immigrant women from west Africa were a high-risk group for STDs but more generally, cohabiting was a risk factor for women.
作者采用整群抽样方法，估算了加蓬东部一个拥有3万居民的城市中，性活跃普通人群中4种性传播疾病（STD）的血清阳性率。HIV-1的血清阳性率为2%，乙型肝炎为13.8%，梅毒螺旋体为8.6%，沙眼衣原体为59.6%。乙型肝炎和衣原体的血清阳性率随时间保持稳定，与中非其他国家的记录相似。另一方面，与这些国家相比，梅毒螺旋体的血清阳性率显著较低，且似乎在下降。HIV-1的血清阳性率也较低，但在该城市8年中翻了一番。来自西非的移民女性是性传播疾病的高危人群，但更普遍的是，同居是女性的一个危险因素。
