Article Abstract

Objective: To examine the association between severity of maternal depression and anxiety during pregnancy and the maternal use of medicinal agents and habit-forming substances.

Method: Participants in a prospective study of prenatal DSM-IV depressive and anxiety disorders at the Emory Women’s Mental Health Program who completed weekly documentation of prenatal drug exposure and ≥ 3 administrations of the Hamilton Depression Rating Scale (HDRS) or Hamilton Anxiety Rating Scale (HARS) were included. The primary outcome measures were the HDRS and HARS. Correlation coefficients were computed for cumulative drug exposure with HDRS area under the curve (AUC) and HARS AUC. Data collection was completed between January 2007 and June 2010.

Results: Among 195 participants, both HDRS AUC and HARS AUC were negatively correlated with prenatal vitamin exposure (r = -0.22 [P = .002] and r = -0.26 [P = .0003], respectively) and positively correlated with tobacco (r = 0.21 [P = .003] and r = 0.20 [P = .006], respectively) and hypnotic (r = 0.28 [P < .0001] and r = 0.19 [P = .008], respectively) exposure. Only HDRS AUC correlated with exposure to antiemetics (r = 0.14 [P = .05]), opioid analgesics (r = 0.14 [P = .05]), and all prescription drugs (r = 0.16 [P = .02]). Only HARS AUC correlated with benzodiazepine exposure (r = 0.17 [P = .02]).

Conclusions: Both prenatal depression and anxiety are associated with decreased prenatal vitamin compliance and increased use of hypnotics and tobacco, but only depression is associated with exposure to a broader array of medications targeting physical symptoms that often accompany depression. These findings confirm and extend previous studies, underscoring the importance of addressing prenatal depression and anxiety.
