Martelon MK, Wilens TE, Anderson JP, Morrison NR, Wozniak J. Are obstetrical, perinatal, and infantile difficulties associated with pediatric bipolar disorder? Bipolar Disord 2012: 14: 507–514. © 2012 The Authors. Journal compilation © 2012 John Wiley & Sons A/S. Objectives: Despite increasing acknowledgement of bipolar disorder (BD) in childhood, there is a paucity of literature that has investigated obstetrical, perinatal, and infantile difficulties and their potential link with BD. To this end, we examined difficulties during delivery, immediate post‐birth, and infancy and the association with BD in childhood. Methods: From two similarly designed, ongoing, longitudinal, case‐control family studies of pediatric BD (N = 327 families), we analyzed 338 children and adolescents [mean (± standard deviation) age: 12.00 ± 3.37 years]. We stratified them into three groups: healthy controls (N = 98), BD probands (N = 120), and their non‐affected siblings (N = 120). All families were comprehensively assessed with a structured psychiatric diagnostic interview for psychopathology and substance use. Mothers were directly questioned regarding the pregnancy, delivery, and infancy difficulties that occurred with each child using a module from the Diagnostic Interview for Children and Adolescents‐Parent Version (DICA‐P). Results: Mothers of BD subjects were more likely to report difficulties during infancy than mothers of controls [odds ratio (95% confidence interval) = 6.6 (3.0, 14.6)]. Specifically, children with BD were more likely to have been reported as a stiffened infant [7.2 (1.1, 47.1)] and more likely to have experienced ‘other’ infantile difficulties [including acting colicky; 4.9 (1.3, 18.8)] compared to controls. We found no significant differences between groups in regards to obstetrical or perinatal difficulties (all p values > 0.05). Conclusions: While our results add to previous literature on obstetrical and perinatal difficulties and BD, they also highlight characteristics in infancy that may be prognostic indicators for pediatric BD.
