Introduction Sexually transmitted infections (STIs) in pregnant women are health problems that lead to serious medical complications and consequences. This study aimed to investigate the prevalence of six STIs among pregnant women attending a centre of prenatal diagnosis.

Methods From Feb 2008 to Dec 2010, women who attending centre of prenatal diagnosis of Nanjing maternity and child health hospital seeking for medical care were enrolled in this study. A case-control study was conducted that 42 case women who suffered a medically unexplained spontaneous abortion and 159 control women who had no history of spontaneous abortion and had at least one living child. Six kinds of sexually transmitted infections such as Chlamydia trachomatis, Neisseria gonorrhoeae, Mycoplasma genitalium, Trichomonas vaginalis, Mycoplasma hominis, and Ureaplasma urealyticum was detected by using the DiaPlexQTM STI-6 Detection Kit.

Results The overall prevalence of any STI was 11.90% in case women while 16.98% in control women. Mycoplasma genitalium and Trichomonas vaginalis were not found in case women and these in 0.63% control women. Chlamydia trachomatis and Ureaplasma urealyticum were detected in 4.76% and 11.90% of case women which were higher than these in control women; None Neisseria gonorrhoeae were found in case women while in 4.40% control samples. Mycoplasma hominis were 2.38% in case and 9.43% in control. The lack of association between STIs and spontaneous abortion was found in this study.

Conclusion Comparison with reported data, unusually low prevalence of Mycoplasma genitalium and Trichomonas vaginalis were found in Chinese women attending a centre of prenatal diagnosis who residing in the middle and lower reaches of the Yangtze River. While screening all pregnant women with these STI-6 PCR method will save a lot of time, the Chinese Mycoplasma genitalium and Trichomonas vaginalis prevalence remains low and this STI-6 Detection Kit is unlikely to be cost effective.
