Sexually transmitted diseases during pregnancy in Louisiana, 2007-2009: high-risk populations and adverse newborn outcomes

Abstract

Background: The aims of the study were to determine the prevalence of sexually transmitted diseases during pregnancy (STDs/P) in Louisiana, the association of maternal characteristics with STDs/P, and the association of STDs/P with low birth weight and preterm birth.

Methods: STDs surveillance data from 2006-2009 were linked with 2007-2009 birth certificate data. The linked data were used for analyses. The data were limited to infections of chlamydia, gonorrhea, and syphilis during pregnancy. Logistic regression was applied to evaluate associations.

Results: The prevalence of chlamydia, gonorrhea, and syphilis during pregnancy was 5.5%, 1.6%, and 0.3%, respectively, among women who had a live birth between 2007 and 2009. Maternal race, ethnicity, age, education, marital status, and Medicaid paid for delivery were associated with STDs/P (p-value < .05). Only infection with gonorrhea during pregnancy was associated with preterm birth [adjusted OR: 1.20 (CI95%: 1.08-1.33)].

Conclusions: The prevalence of STDs/P in Louisiana remains high. Low-educated, young, black, single, and economically disadvantaged mothers were at high risk for STDs during pregnancy. Women diagnosed with gonorrhea during pregnancy were more likely to experience preterm birth.
