Interaction effect of oxytocin receptor (OXTR) rs53576 genotype and maternal postpartum depression on child behavioural problems.

ABSTRACT: Previous studies have reported interaction effects of oxytocin receptor genotype (rs53576) and environmental factors on mental health in youth. However, the findings are mixed, especially regarding the type of allele (i.e., A vs. G), and it remains unanswered whether such an interaction presents at an early stage of development. Thus, using a unique longitudinal birth cohort sample in Japan (n?=?568), we examined whether there was an effect of the interaction between the OXTR rs53576 genotype and maternal postpartum depression, as an environmental risk, on behavioural problems in children. Child behavioural problems (internalising and externalising problems) were ascertained using the Strengths and Difficulties Questionnaire when children were 6 years old. Maternal postpartum depression was measured using the Edinburgh Postnatal Depression Scale when children were at 2 months and 10 months of age. The results revealed a significant effect in the interaction between OXTR rs53576 genotype and maternal postpartum depression on externalising problems in children with AA genotype (??=?0.136, 95% CI 0.032 to 0.240), but not in those with GG/GA genotype. This indicates that an interaction of vulnerable genotypes (i.e., A allele of OXTR rs53576) with an environmental burden (i.e. maternal postpartum depression) may be one of the potential elements that predisposes the infant to developing behavioural problems early in life. Hence, special attention needs to be paid to children exposed to environmental risks such as maternal postpartum depression, to facilitate the provision of appropriate care.

Project description:BackgroundMaternal abnormal glucose tolerance during pregnancy may adversely affect offspring cognition and behaviour, but few prospective studies investigated this association at multiple points throughout childhood.ObjectivesWe hypothesised that maternal abnormal glucose tolerance is associated with child cognitive and behavioural outcomes in early and mid-childhood.MethodsWe examined the associations of maternal abnormal glucose tolerance at 26-28 weeks of pregnancy with offspring cognitive and behavioural scores in 1421 children in the Project Viva pre-birth cohort. In early (mean 3.3 years) and mid-childhood (mean 7.9 years), we measured child cognition using validated instruments, the Kaufman Brief Intelligence Test, Wide Range Assessment of Memory and Learning, and the Wide Range Assessment of Visual Motor Abilities (WRAVMA); we assessed parent- and teacher-rated behavioural outcomes with the Strengths and Difficulties Questionnaire and the Behavioural Rating Inventory of Executive Function. We used linear regression models adjusted for potential confounders (maternal race/ethnicity, pre-pregnancy BMI, intelligence, age, parity, smoking status, education, and household income at enrolment, in addition to child's sex and age at assessment).ResultsOf 1421 mothers, 69 (4.9%) had gestational diabetes mellitus, 43 (3.0%) impaired glucose tolerance, 122 (8.6%) isolated hyperglycaemia, and 1187 (83.5%) normal glucose tolerance. Offspring born to women with gestational diabetes mellitus had lower total WRAVMA scores (-3.09 points; 95% CI -6.12, -0.05) in early childhood compared with offspring of women with normal glucose tolerance. None of the abnormal glucose tolerance categories during pregnancy were associated with any of the cognitive outcomes (verbal, non-verbal, and visual motor scores) or behavioural measures in mid-childhood.ConclusionsChildren born to mothers who had gestational diabetes mellitus had slightly lower scores on one cognitive test in early childhood. We found no evidence to support that maternal abnormal glucose tolerance was associated with cognitive or behavioural development in mid-childhood.
