Reported US cases of chlamydia and gonorrhea have increased since 2000, whereas studies in select populations suggest that the prevalence of these diseases has decreased. We sought to determine if these diagnoses are increasing among pregnant women delivering at our center.
Methods
This is a retrospective study of women delivering at least 1 infant >18 weeks of gestation at the Medical University of South Carolina for 11 years (2008–2018). Using the perinatal information system, we collected maternal race, age, insurer, and chlamydia and gonorrhea screening results during the pregnancy of record.
