Psychiatric and obstetric characteristics of pregnant crack users admitted to a referral center in Southern Brazil.

Background: Psychoactive substance use among pregnant women has reached alarmingly high rates. Our aim was to characterize the psychiatric and clinical profiles of pregnant crack users in Brazil.

Methods: This was a cross-sectional study of 24 pregnant crack users admitted to a referral hospital for psychiatric disorders in pregnant women, in Porto Alegre, Brazil, over three years. The following instruments were applied: a clinical-obstetric questionnaire; the condensed version of the Addiction Severity Index; a diagnostic interview for psychoactive substance use based on DSM-5; the Mini International Neuropsychiatric Interview for DSM-IV; and the Semi-Structured Clinical Interview for DSM-IV Axis II Personality Disorders (SCID-II).

Results: Most patients had severe crack dependence and used other substances, such as tobacco, cannabis, and alcohol. The median duration of crack use was three years, ranging between three and 12 years. Most women subsisted from illegal or informal activities; a fifth had previously been arrested and often had relationship problems. Twenty percent had HIV (n = 5), and 37.5% (n = 9) had syphilis. Borderline personality disorder was the most prevalent mental condition (62.5%), followed by suicidal tendencies (45.8%), hypomanic episodes due to substance use (37.5%), and past major depressive episodes (33.3%).

Conclusions: An alarmingly high prevalence of consumption of other drugs, psychiatric disorders, and difficult-to-treat personality disorders was observed in our study. Investigating the psychiatric profile of women who use substances is essential to minimize the impacts on the mother and child, optimize therapeutic approaches to comorbidities, and enable more effective relapse prevention.
