摘要

Background: Sexually transmitted infections (STIs) are an increasingly critical and costly health problem for American childbearing women. Pregnant women who misuse substances are more likely to engage in risky sexual behavior that leads to STIs. Substance use and risky sex during pregnancy are both associated with numerous negative consequences for the woman and the developing fetus. Study Design: A two-group, randomized controlled trial. Participants: Recruitment of 50 pregnant women (30% Latina; 24.4 years old [SD=5.31]) with an average of 13 weeks gestation (SD=4.5 weeks) was conducted at a prenatal clinic in a large inner-city hospital. Recruitment took place between 2015 and 2016, and data analysis took place in 2016. Intervention: A computer-delivered, single-session brief motivational intervention plus booster session addressing both substance use and STI risk. Objective: To assess participants' perceptions of the intervention and to examine the preliminary efficacy in reduction of substance use and risky sex at 4-month follow-up assessment. Results: There were consistently very high ratings of acceptability of the intervention, ranging between 6.3 and 6.8 on a 1-7 scale. At the 4-month follow-up, participants in the intervention arm reported a significantly larger reduction (54%) in any marijuana or alcohol use compared with participants in the control group (16%) (p=0.015) based on two-group clustered logistic regression using a generalized estimating equations approach. There was a higher reduction in condomless vaginal sex at follow-up in the health checkup for expectant moms (HCEM) arm than control (27% vs. 5%), although this was not significant (p=0.127). Conclusions: The results of this pilot study are encouraging with respect to the acceptability and preliminary efficacy of an intervention in reducing alcohol/marijuana use and condomless sex during pregnancy, supporting the next step of testing the intervention in a larger sample.
