Profile of Chronic Comorbid Conditions and Obstetrical Complications Among Pregnant Women With Human Immunodeficiency Virus and Receiving Antiretroviral Therapy in the United States

Background To evaluate the frequency and associated characteristics of chronic comorbid conditions and obstetrical complications among pregnant women with human immunodeficiency virus (HIV) and receiving antiretroviral therapy (ART) in comparison to those without HIV. Methods We compared 2 independent concurrent US pregnancy cohorts: (1) with HIV (International Maternal Pediatric Adolescent AIDS Clinical Trials Protocol P1025, 2002–2013) and (2) without HIV (Consortium for Safe Labor Study, 2002–2007). Outcomes were ≥2 chronic comorbid conditions and obstetrical complications. For women with HIV, we assessed whether late prenatal care (≥14 weeks), starting ART in an earlier era (2002–2008), and a detectable viral load at delivery (≥400 copies/mL) were associated with study outcomes. Results We assessed 2868 deliveries (n = 2574 women) with HIV and receiving ART and 211 910 deliveries (n = 193 170 women) without HIV. Women with HIV were more likely to have ≥2 chronic comorbid conditions versus those without HIV (10 vs 3%; adjusted OR [AOR]: 2.96; 95% CI: 2.58–3.41). Women with HIV were slightly less likely to have obstetrical complications versus those without HIV (both 17%; AOR: .84; 95% CI: .75–.94), but secondarily, higher odds of preterm birth <37 weeks. Late entry to prenatal care and starting ART in an earlier era were associated with a lower likelihood of ≥2 chronic comorbidities and obstetrical complications; detectable viral load at delivery was associated with a higher likelihood of obstetric complications. Conclusions Pregnant women with HIV receiving ART have more chronic comorbid conditions, but not necessarily obstetrical complications, than their peers without HIV.
