Study type: Observational

Background: The North Carolina Early Pregnancy Study (EPS) was held from 1982 to 1986. Women who were trying to get pregnant took part in the study. They collected urine samples. They kept diaries. They filled out surveys. They answered questions about their partners. They were asked about their drug use. Data about air pollution and other exposures were also collected. A follow-up study was held from 2010 to 2011. Researchers want to use the data and samples to study factors that affect reproductive success.

NCT ID: NCT03194308 Completed - HIV Prevention Clinical Trials

Safer Conception for Women - Understanding Use of Periconception PrEP

Start date: November 13, 2017
Phase: Phase 4
Study type: Interventional

Women who choose to conceive with an infected or unknown serostatus partner in HIV-endemic settings need prevention strategies to reduce periconception HIV acquisition risk. Women at high risk for acquiring HIV during pregnancy need risk reduction strategies to protect themselves and their babies. Evaluating uptake of and adherence to antiretrovirals as pre-exposure prophylaxis in this population is crucial to understanding whether and how this novel prevention strategy should be incorporated into HIV-risk reduction packages for at- risk women planning or with pregnancy.
