Syphilis screening among 27,150 pregnant women in South Chinese rural areas using point-of-care tests.

OBJECTIVES

To determine the prevalence and correlates of syphilis among pregnant women in rural areas of South China.

METHODS

Point-of-care syphilis testing was provided at 71 health facilities in less developed, rural areas of Guangdong Province. Positive samples were confirmed at a local referral center by toluidine red unheated serum tests (TRUST) and Treponema pallidum particle agglutination (TPPA) tests.

RESULTS

Altogether 27,150 pregnant women in rural Guangdong were screened for syphilis. 106 (0.39%) syphilis cases were diagnosed, of which 78 (73.6%) received treatment for syphilis. Multivariate analysis revealed that older pregnant women (31-35 years old, aOR 2.7, 95% CI 0.99-7.32; older than 35 years old, aOR 5.9, 95% CI 2.13-16.34) and those with a history of adverse pregnant outcomes (aOR 3.64, 95% CI 2.30-5.76) were more likely to be infected with syphilis.

CONCLUSIONS

A high prevalence of syphilis exists among pregnant women living in rural areas of South China. Enhanced integration of syphilis screening with other routine women's health services (OB GYN, family planning) may be useful for controlling China's syphilis epidemic.
