Seroprevalence of Sexually Transmitted Infections (Hepatitis B Virus, Hepatitis C virus, Syphilis, and HIV) in Pregnant Women and Evaluation of Sociodemographic Characteristics and Awareness Regarding STIs in North Indian Population

Context: Sexually transmitted infections (STIs) are a problem of increasing concern among men and women. They can affect fertility, increase maternal and neonatal morbidity, and can become a burden on both physical and emotional health. Owing to lack of awareness and partly due to the social stigma attached, couples do not come forward for screening. Antenatal testing for STIs is an effective strategy recommended to detect STIs in this subset of the population. Aims: To estimate the seroprevalence of four STIs (hepatitis B, hepatitis C virus, HIV, and syphilis) in pregnant women, to evaluate its correlation with sociodemographic characteristics and sexual behavior, and to check awareness regarding STIs. Settings and Design: It was an observational study on 500 pregnant women attending an antenatal clinic at a tertiary care hospital in rural Haryana, India. Methods and Material: Pregnant women were screened for four STIs – hepatitis B, hepatitis C virus, HIV, and syphilis. Statistical Analysis Used: The sample size was calculated considering the mean reported seroprevalence of infections in pregnant women in previous studies. The power of the study was kept 80% and the alpha error was 0.05. Results: Seroprevalence for STIs in pregnancy was 5.2% – hepatitis C virus (2.6%), hepatitis B (2.4%), and syphilis (0.4%). Conclusions: Viral STIs are more prevalent among pregnant women. Antenatal screening is an effective strategy for the detection of STIs in pregnant women.
