Exploration of Differences between Women Who Do and Do Not Disclose Their Marijuana Use during Pregnancy

Abstract

Objective This study aimed to explore demographic and health-related factors that may differentiate women who do and do not disclose their marijuana use during pregnancy. Study Design The current study is a secondary analysis of data from a prospective cohort of pregnant women identified as using marijuana during pregnancy via a variety of assessment tools including self-report, urine screen, and obstetrics record abstraction. The cohort included a convenience sample of women recruited from several antenatal clinics at The Ohio State University Wexner Medical Center (OSUWMC). To be eligible, women needed to be within the first or second trimester of their pregnancy, 16 to 50 years of age, able to communicate in English, and intended to deliver at OSUWMC. Chi-square, independent samples t-tests, and logistic regression analyses were used to explore differences between those who did and did not disclose their use in relation to physical and mental health diagnoses, adverse experiences, use of other substances, and demographics. Results Women who used marijuana during their pregnancy and had mental/physical health data available comprised the current sample (n = 109). Women who attended college were more likely to disclose their marijuana use compared with women who did not attend college (p < 0.001). Women who experienced homelessness (p < 0.01) or self-reported alcohol use during pregnancy (p < 0.001) were significantly more likely to disclose their marijuana use. Conclusion Findings, suggesting disclosure of other substance use and adverse experiences, such as homelessness, may increase the likelihood that pregnant women will voluntarily disclose their marijuana use to providers. Findings did not reflect racial differences nor significant differences in mental/physical health status among women based on their disclosure. Future research with larger datasets is needed to build on these findings by confirming results, as well as exploring additional factors, that may more effectively differentiate women who are unlikely to disclose their prenatal marijuana use from those who do disclose their use.
