Syphilis and human immunodeficiency virus infections among pregnant women attending antenatal care clinic of Gondar family guidance association, Northwest Ethiopia: implication for prevention of mother to child transmission

Background Sexually transmitted infections constitute a major public health problem worldwide. Syphilis and HIV infections cause various adverse pregnancy outcomes. Therefore, the aim of this study was to determine the seroprevalence of HIV and syphilis infections among pregnant women at Gondar Family Guidance Association clinic, northwest Ethiopia. Methods A retrospective study was conducted using sociodemographic and laboratory data obtained from registration books of Gondar Family Guidance Association clinic from January 2011 to April 2015. A binary logistic regression model was fit to identify factors associated with HIV and syphilis infections. Odds ratios with 95% confidence intervals were calculated to determine the strength of association between factors associated with HIV and syphilis infections. A p-value [less than or equai to]0.05 was considered statistically significant. Results A total of 3504 pregnant women were included in the study from January 2011 to April 2015. The seroprevalence of HIV, and syphilis were 145 (4.1%) and 66(1.9%), respectively. Twenty-three (0.66%) women were co-infected. Age group 20-29 years (AOR: 3.86; 95% CI: 1.36-10.89), age group [greater than or equai to]30 years (AOR: 6.08; 95% CI: 2.04-18.14) compared to age < 20 year, and HIV-infection (AOR: 14.6; 95% CI: 8.49-25.18) were significantly associated with syphilis infection. There was a decline in trend seroprevalence of HIV from 5.2% in 2011 to 2.1% in 2015; and decline in syphilis seroprevalence from 2.6% in 2011 to 1.6% in 2015 but not statistically significant. Conclusion The data showed that syphilis and HIV infections are still critical public health concerns among pregnant women. Screening of all pregnant women for these infections is valuable. Further community-based studies to identify risk factors are necessary. Keywords: Human immunodeficiency virus, Pregnant women, Seroprevalence, Syphilis
