- OBJECTIVEAdipocytokines participate in the regulation of glucose metabolism and foetal development. The transcription factor activating protein 2B (TFAP2β) has been associated with adipocytokine regulation, and gene variations with type 2 diabetes and obesity. This study investigated associations between maternal TFAP2B variation, adipocytokines levels and maternal and neonatal anthropometric characteristics.DESIGN AND METHODSA population-based sample of women was followed from delivery to six months postpartum. Adiponectin, leptin and interleukin-6 levels at delivery, and maternal as well as neonatal anthropometric variables were assessed. The TFAP2β intron 1 variable number tandem repeat (VNTR) was genotyped.RESULTSMaternal interleukin-6 correlated positively with leptin at delivery, with peripartum weight changes and weight of newborn males, adjusted for potential confounders. Leptin at delivery was associated with TFAP2β intron 1 VNTR genotype, adjusted for confounders, maternal weight and negatively with birth weight among female neonates. A path model suggested a link between TFAP2β genotype, leptin levels and newborn females' weight.CONCLUSIONSThe present results stress a role for the TFAP2 β in adiposity-related conditions and intrauterine growth. The association between neonatal birth weight and maternal adipocytokine levels, together with the observed sex effect, call for further studies on the mechanisms behind neuro-endocrine foetal programming.

- IntroductionThe Hypothalamic-Pituitary-Adrenal Axis (HPA axis) has been implicated in the pathogenesis of many affective disorders. Peripartum depression is a condition that includes depressive episodes occurring during pregnancy and the postpartum period. During uncomplicated pregnancy, mean cortisol levels rise substantially, mostly due to high levels of corticotropin releasing hormone produced by the placenta (p-CRH). The latter also suppresses hypothalamic CRH, leading to hypo-cortisolemia after partus. Cortisol concentration is usually normalised within two weeks after delivery. Failure of the above process results in continuing hypo-cortisolemia, which might increase susceptibility to PPD.Objectives/aimsThe current study aims to investigate the relationship between evening salivary cortisol levels and depression during the peripartum period.MethodsThree hundred and forty six pregnant women were asked to participate in the study. They completed the Edinburgh Postnatal Depression Scale (EPDS) and the Spielberger State-Trait Anxiety Inventory-State version (STAI-S) at the 36th week of pregnancy and the 6th week after delivery. At both times, study subjects were also asked to collect evening salivary samples by using a mail-delivered kit. Moreover, they were interviewed at the 36th week of pregnancy using the Mini International Neuropsychiatric Interview (MINI).ResultsPreliminary results indicate significantly higher evening salivary cortisol levels in depressed women during late pregnancy compared to healthy controls. No difference in cortisol levels was found between women with postpartum depression and healthy controls.ConclusionsOur study results support the hypothesis that depression during pregnancy resembles melancholic depression characterized by hyperactivity of the HPA-axis and hyper-cortisolemia.

- IntroductionPostpartum depression (PPD), with a prevalence of about 10-15% in developed countries, has a major impact on both mother and child. Personality traits, mainly neuroticism, have been associated with affective disorders and in particular postpartum depression.ObjectivesTo examine if neuroticism is associated with depressive symptoms in pregnancy and post-partum, controlling for possible confounding factors.MethodsSince September 2009, all pregnant women in Uppsala, Sweden have been asked to participate in BASIC study, which is a population based, prospective study on mental health during pregnancy and post-partum. Women filled in the Swedish Scales of Personality (SSP), as well as the Edinburg Postnatal Depression Scale (EPDS) in pregnancy week 32. EPDS was also administered 6 weeks and 6 months postpartum. A factor analysis of SSP traits was conducted in our material and the three factor structure comprising neuroticism, aggressiveness and sensation seeking was confirmed. The association between personality traits and depressive symptoms was examined using binary logistic regression. High levels of neuroticism, aggressiveness and sensation seeking were defined as the highest quartile of each factor.ResultsHigh levels of neuroticism were strongly associated with depressive symptoms during pregnancy as well as at 6 weeks and 6 months post-partum, while aggressiveness and sensation seeking were not. After controlling for confounding factors, such as previous history of depression, employment, education, partner support and breastfeeding, neuroticism remained a significant predictor for depressive symptoms, at all three time-points.ConclusionsNeuroticism is an independent strong predictor of depressive symptoms during pregnancy and the postpartum period.
