Prevalence of Substance Use During Pregnancy and the Related Factors: A Study from Southeast Iran

Background: substance use during pregnancy has an increasing trend in all socio-economic classes. in addition to the fetal consequences, this problem has many other economic and social harmful effects. this study aimed to determine the prevalence of substance use and its related factors in pregnant women. methods: this cross-sectional study was performed using a self-administered questionnaire on 587 pregnant women in kerman, iran who visited public health centers and private offices to receive prenatal care. participants were recruited from january to february 2020 using a multistage sampling method. results: the most prevalent substances used during pregnancy were waterpipe (8.5%), opium (2.6%), and alcohol (1.7%). substance use in the first-degree relatives strongly correlated with substance use in pregnant women (odds ratio [or] = 7.26). the low educational level of pregnant women’s husbands was also a predictor of substance use in pregnant women (or = 3.15).conclusion: since substance use by family members was the strongest correlate of drug use during pregnancy, family-based interventions should be tailored to address early detection of such vulnerable women and to provide appropriate counseling services.
