To establish the prevalence of syphilis in pregnant women in Mozambique and evaluate present diagnostic methods, 1468 pregnant women in eight of the country's 10 provinces were examined using the Venereal Disease Research Laboratory (VDRL) test. Positive serum samples were also analysed using the Treponema pallidum haemagglutination (TPHA) assay and one group was also analysed using the fluorescent treponemal antibody absorbed (FTA-ABS) test. The prevalence of VDRL seroreactivity was found to be between 4.5% and 14.6%, whereas the prevalence of treponemal disease as verified by TPHA or FTA-ABS tests was between 1.6% and 9.8%. It is concluded that syphilis is relatively common among pregnant women in Mozambique. The predictive value of a positive VDRL test, when adequately performed, was
为确定莫桑比克孕妇梅毒的患病率并评估当前的诊断方法，该国10个省份中的8个省份的1468名孕妇接受了性病研究实验室（VDRL）检测。对VDRL检测呈阳性的血清样本还采用梅毒螺旋体血细胞凝集试验（TPHA）进行了分析，并且对其中一组样本采用了荧光密螺旋体抗体吸收试验（FTA-ABS）进行了分析。结果发现，VDRL血清反应阳性率在4.5%至14.6%之间，而经TPHA或FTA-ABS检测证实的梅毒患病率在1.6%至9.8%之间。得出的结论是，梅毒在莫桑比克孕妇中相对常见。当VDRL检测充分执行时，其阳性预测值为
