Background Allostatic load (AL) is an index of multi-system physiological "wear-and-tear," operationalizing emergent chronic disease risk and predicting morbidity and mortality. AL has been proposed as an organizing framework for studying pregnancy outcomes and additional AL biomarkers for the study of maternal health would be valuable. Objectives To test whether adverse perinatal outcomes are associated with postpartum AL and if including vitamin D deficiency (serum 25(OH)D

Complications related to preterm birth (PTB) and low birth weight (LBW) are leading causes of infant morbidity and mortality. Prenatal depression is a hypothesized psychosocial risk factor for both birth outcomes. The purpose of this systematic review was to examine evidence published between 1977 and 2013 on prenatal depression and risks of these primary adverse birth outcomes. A systematic search of the PUBMED and PsycINFO databases was conducted to identify studies testing the associations between prenatal depressive symptoms, or diagnoses of depression, and risk of PTB or LBW. We systematically selected 50 published reports on PTB and length of gestation, and 33 reports on LBW and BW. Results were reviewed by two independent reviewers and we evaluated the quality of the evidence with an established systematic review method, the Newcastle Ottawa Scale. We then undertook a narrative synthesis of the results following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Less than a quarter of 50 published reports found that prenatal depression was significantly associated with PTB or gestational age. In contrast, slightly more than half of the 33 reports found that prenatal depression was associated with LBW or BW. When weighing methodological features, we determined that the effects of prenatal depression on LBW are more consistent than effects on length of gestation or PTB. Although the evidence may not be strong enough to support routine depression screening for risk of adverse outcomes, screening to enable detection and timely treatment to reduce risk of postpartum depression is warranted. Further rigorous research on prenatal depression and adverse birth outcomes is needed.

Prenatal vitamin D deficiency and prenatal depression are both separately associated with adverse perinatal outcomes; however, to our knowledge no studies have investigated the effects of having both risk factors. Our objective was to determine to what extent vitamin D deficiency predicts adverse perinatal outcomes and whether elevated depressive symptoms in pregnancy places women at additional increased risk. This study was a secondary data analysis of prospective data collected from a cohort of pregnant women (N = 101) in an obstetric clinic of a large medical center. Maternal vitamin D deficiency (serum 25(OH)D [less than or equal to] 20 ng/ml) and depressive symptoms (Edinburgh Postnatal Depression Scale, EPDS) were assessed in early pregnancy. A composite of four adverse perinatal outcomes (low birth weight, preterm birth, small-for-gestational age, and preeclampsia) were abstracted from medical charts. Nineteen of the 101 women had one or more adverse perinatal outcome and 84% with an adverse outcome (16/19) were not White. Both prenatal and time of delivery vitamin D deficiency were associated with developing an adverse outcome compared to those vitamin D sufficient (prenatal relative risk 3.43; 95% CI 1.60-7.34, p = 0.004; delivery time relative risk 5.14, 95% CI 2.68-9.86, p = 0.004). These both remained significant after adjusting for BMI. A higher rate of adverse outcome was found when women had both prenatal vitamin D deficiency and elevated depressive symptoms (EPDS [greater than or equal to] 10). Sixty percent with both risk factors had an adverse perinatal outcome versus 17% with only one or neither risk factor (relative risk 3.60; 95% CI 1.55-8.38, p = 0.045), worthy of investigation with larger samples. Together, prenatal vitamin D deficiency and elevated depressive symptoms in pregnancy may increase risk for adverse perinatal outcomes, especially in racial minorities. Obstetric providers should consider routine prenatal depression screening. The impact of vitamin D supplementation to reduce risk for adverse perinatal outcomes should be studied in prospective trials. Our results suggest that supplementation early in pregnancy might be especially beneficial for depressed women., Author(s): Eynav Elgavish Accortt [sup.1] , Amy Lamb [sup.1] , James Mirocha [sup.2] , Calvin J.

Resting frontal electroencephalographic (EEG) asymmetry has been hypothesized to tap a diathesis toward depression or other emotion-related psychopathology. Frontal EEG asymmetry was assessed in college women who reported high (n = 12) or low (n = 11) levels of premenstrual negative affect. Participants were assessed daring both the follicular and the late luteal phases of the menstrual cycle. Women reporting low premenstrual dysphoric symptomatology exhibited greater relative left frontal activity at rest than did women high in premenstrual dysphoric symptomatology, an effect that was not qualified by phase of cycle. Although women with extreme levels of symptomatology were assessed, the question of whether such symptoms qualified for premenstrual dysphoric disorder criteria was not assessed. These results are consistent with a diathesis-stress model for premenstrual dysphoric symptomatology. Keywords: EEG asymmetry, premenstrual dysphoria, risk, diathesis
