Physiological regulation in infants of women with a mood disorder: examining associations with maternal symptoms and stress / Katrina C. JOHNSON in Journal of Child Psychology and Psychiatry, 55-2 (February 2014)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 55-2 (February 2014) . - p.191-198 Titre : Physiological regulation in infants of women with a mood disorder: examining associations with maternal symptoms and stress Type de document : Texte imprimé et/ou numérique Auteurs : Katrina C. JOHNSON, Auteur ; Patricia A. BRENNAN, Auteur ; Zachary N. STOWE, Auteur ; Ellen LEIBENLUFT, Auteur ; D. Jeffrey NEWPORT, Auteur Article en page(s) : p.191-198 Langues : Anglais (eng) Mots-clés : Bipolar  depression  RSA  heart rate  vagal  stress  infants  human Index. décimale : PER Périodiques Résumé : Background The offspring of mothers with mood disorders may evidence increased behavioral problems as early as preschool; however, no study to date has examined psychophysiological characteristics during infancy, particularly among offspring of mothers diagnosed with bipolar disorder. Elucidating psychobiological mechanisms of risk early in development is critical to inform prevention and early intervention efforts. Method This study compared physiological and behavioral responsivity in 6-month-old infants (N = 329) of mothers with lifetime histories of bipolar disorder (BD, n = 44), major depressive disorder (MDD, n = 244), or no history of Axis I disorders (CTL, n = 41). Infant respiratory sinus arrhythmia (RSA) was measured in a laboratory stressor paradigm. Measures of infant affect and behavior during mother–infant interaction, current maternal depressive symptoms, and exposure to stressful life events were examined with respect to diagnostic group and RSA. Results Groups did not differ in baseline RSA or infant affect measures. However, during the stressor task, infants of mothers with BD evidenced increases in RSA, while infants of MDD and CTL mothers evidenced decreases in RSA. Though levels of postnatal stress and current levels of maternal depressive symptoms differed among groups, neither of these factors predicted infant psychophysiological responses. Conclusions At 6 months of age, infants of motrs with BD show differences in psychophysiological regulation. These differences cannot be accounted for by perinatal outcome, current maternal depressive symptoms, or exposure to stressful life events, and thus may reflect endophenotypic markers of psychopathological risk.

School-age social behavior and pragmatic language ability in children with prenatal serotonin reuptake inhibitor exposure / Erica L. SMEARMAN in Development and Psychopathology, 32-1 (February 2020)  

Public ISBD [article]  inDevelopment and Psychopathology > 32-1 (February 2020) . - p.21-30 Titre : School-age social behavior and pragmatic language ability in children with prenatal serotonin reuptake inhibitor exposure Type de document : Texte imprimé et/ou numérique Auteurs : Erica L.

BRENNAN, Auteur Article en page(s) : p.21-30 Langues : Anglais (eng) Mots-clés : Autism Spectrum Disorder  language  neurodevelopment  prenatal exposure  serotonin Index. décimale : PER Périodiques Résumé : Studies examining associations between fetal serotonin reuptake inhibitor (SRI) exposure and child autism spectrum disorder (ASD) diagnoses or delayed language remain mixed and rarely prospectively follow children or employ gold-standard assessments. We prospectively followed a cohort of mother-child dyads from pregnancy through early elementary school (N = 178), and obtained maternal and alternate-caregiver ratings of behaviors related to ASD (N = 137), as well as direct, gold-standard assessments of child ASD symptoms and pragmatic language among dyads who experienced prenatal depression and either took SRIs or were medication free during pregnancy (N = 44). Prenatal SRI exposure was related to maternal ratings of ASD-related behaviors (beta = 0.24 95% confidence interval; CI [0.07, 0.48]), and, among boys, alternative caregiver ratings (males-only beta = 0.28 95% CI [0.02, 0.55], females-only beta = -0.21 95% CI [-0.63, 0.08]). However, results of our direct assessments suggest an association between SRI exposure and reduced pragmatic language scores (beta = -0.27, 95% CI [-0.53, -0.01], but not ASD (Autism Diagnostic Observation Schedule beta = 0.14 95% CI [-0.15, 0.41]; Social Responsiveness Scale beta = 0.08 95% CI [-0.25, 0.40]). These discrepancies point to issues regarding how ASD is assessed, and the possibility that SRIs may be more strongly associated with language or other broader behaviors that coincide with ASD. Larger prospective studies that incorporate thorough, gold-standard assessments of ASD, language, and other ASD-related behaviors are needed.

Social stress and the oxytocin receptor gene interact to predict antisocial behavior in an at-risk cohort / Erica L. SMEARMAN in Development and Psychopathology, 27-1 (February 2015)  

Public ISBD [article]  inDevelopment and Psychopathology > 27-1 (February 2015) . - p.309-318 Titre : Social stress and the oxytocin receptor gene interact to predict antisocial behavior in an at-risk cohort Type de document : Texte imprimé et/ou numérique Auteurs : Erica L.

JOHNSON, Auteur Article en page(s) : p.309-318 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Polymorphisms in the oxytocin receptor gene are commonly associated with prosocial behaviors in the extant literature, yet their role in antisocial behaviors has rarely been explored, particularly during the transition from adolescence to early adulthood. We examined a prospective cohort (N = 404), collecting youth, mother, and clinician reports of conduct-disordered and antisocial behavior at ages 15 and 20. The oxytocin receptor gene rs53576 polymorphism was hypothesized to interact with social stress to predict antisocial outcomes. Structural equation modeling results revealed a significant main effect at age 15 (p = .025); those with the G allele exhibited higher levels of conduct problems. Structural equation modeling revealed a significant Gene × Environment interaction at age 20 (p = .029); those with the G allele who experienced high social stress exhibited higher levels of antisocial behavior. Heterozygous (AG) grouping models were compared, and parameter estimations supported G dominant groupings. These novel findings suggest that rs53576 polymorphisms may influence social salience and contribute to risk for antisocial outcomes, particularly under conditions of high social stress.
