Abstract

© 2014 Royal College of Obstetricians and Gynaecologists. Results: Among 1512 women, 1.9% (95% confidence interval, 95% CI, 1.3-2.7) of singleton pregnancies resulted in a stillbirth and 32.9% (95% CI 30.6-35.4) had at least one adverse pregnancy outcome. Of 1483 singleton live births, 19.8% (95% CI 17.8-21.9) were PT, 14.2% (95% CI 12.5-16.1) were LBW, 12.6% (95% CI 10.9-14.4) were SGA, and 0.4% (95% CI 0.2-0.9) of infants died within 28 days of birth. Multivariable logistic regression modelling indicated that the following risk factors increased the probability of having one or more adverse pregnancy outcomes: lower maternal body mass index at delivery (odds ratio, OR, 2.2; 95% CI 1.4-3.5), hospitalisation during pregnancy (OR 3.3; 95% CI 2.0-5.3), hypertension during pregnancy (OR 2.7; 95% CI 1.5-4.8), antiretroviral use at conception (OR 1.4; 95% CI 1.0-1.9), and tobacco use during pregnancy (OR 1.7; 95% CI 1.3-2.2). The results of fitting multivariable logistic regression models for PT, LBW, SGA, and SB are also reported.Population: Women infected with HIV enrolled in the Perinatal (2002-2007) and the Longitudinal Study in Latin American Countries (LILAC; 2008-2012) studies of the Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD) International Site Development Initiative (NISDI).Methods: Frequencies of adverse pregnancy outcomes assessed among pregnancies. Risk factors investigated by logistic regression analysis.Main: outcome measures Adverse pregnancy outcomes, including preterm delivery (PT), low birthweight (LBW), small for gestational age (SGA), stillbirth (SB), and neonatal death.Conclusions: Women infected with HIV had a relatively high occurrence of adverse pregnancy outcomes, and some maternal risk factors were associated with these adverse pregnancy outcomes. Interventions targeting modifiable risk factors should be evaluated further.Objective: To examine maternal characteristics associated with adverse pregnancy outcomes among women infected with HIV.Design: Prospective cohort study.Setting: Multiple sites in Latin America and the Caribbean.
