Pregnancy/delivery complications and psychiatric diagnosis. A prospective study.
ABSTRACT We examined the hypothesis that pregnancy and delivery complications result in increased risk for the development of psychiatric disorders. The study sample included 1068 pregnancies classified as chronic fetal hypoxia, other complications, preterm birth, or normal pregnancy/delivery that had initially been studied prospectively from the prenatal period through age 7 years. Subjects were recontacted (ages 18 to 27 years) and lifetime psychiatric diagnoses made with the Diagnostic Interview Schedule. Preterm subjects had significantly higher rates of cognitive impairment. Subjects with chronic fetal hypoxia had higher rates of both cognitive impairment and psychotic disorders, although these differences failed to reach statistical significance due to the small number of cases. With these exceptions, the data did not support the hypothesis that rates of psychiatric disorders are higher among subjects born with complications of pregnancy and delivery than among normal controls born without complications.

ABSTRACT: This issue of the Journal features collaborative follow-up studies of two unique pregnancy cohorts recruited during 1959–1966 in the United States. Here we introduce the Early Determinants of Adult Health (EDAH) study. EDAH was designed to compare health outcomes in midlife (age 40s) for same-sex siblings discordant on birthweight for gestational age. A sufficient sample of discordant siblings could only be obtained by combining these two cohorts in a single follow-up study. All of the subsequent six papers are either based upon the EDAH sample or are related to it in various ways. For example, three papers report results from studies that significantly extended the ‘core’ EDAH sample to address specific questions.We first present the overall design of and rationale for the EDAH study. Then we offer a synopsis of past work with the two cohorts to provide a context for both EDAH and the related studies. Next, we describe the recruitment and assessment procedures for the core EDAH sample. This includes the process of sampling and recruitment of potential participants; a comparison of those who were assessed and not assessed based on archived data; the methods used in the adult follow-up assessment; and the characteristics at follow-up of those who were assessed. We provide online supplementary tables with much further detail. Finally, we note further work in progress on EDAH and related studies, and draw attention to the broader implications of this endeavor.12/2011; 2(06). DOI:10.1017/S2040174411000663

ABSTRACT: We tested the hypothesis that perinatal oxytocin, given to pregnant women to induce labor, is related to offspring bipolar disorder (BP) and worse childhood cognitive performance among offspring. We also tested the association between childhood cognition and later BP.MethodsA population-based birth cohort derived from the Child Health and Development Study (CHDS) which included nearly all pregnant women receiving obstetric care from the Kaiser Permanente Medical Care Plan, Northern California Region (KPNC) between 1959 and 1966. Prospectively obtained medical and offspring cognitive performance were used. Potential cases with BP from the cohort were identified by database linkages. This protocol identified 94 cases who were matched 1:8 to controls.ResultsPerinatal oxytocin was associated with a 2.4 times increased odds of later BP. Oxytocin was also associated with decreased performance on the Raven Matrices, but not on the Peabody Picture Vocabulary Test (PPVT). Childhood cognition was not associated with later BP.LimitationsLoss to follow-up must be considered in all birth cohort studies. In addition, the childhood cognitive battery did not include tests related to multiple domains of cognition which have been associated with later BP. A third limitation is the modest sample size of those exposed to oxytocin.Conclusions This study provides evidence for a potentially important perinatal risk factor for BP and cognitive impairment in childhood. While the association between perinatal oxytocin and offspring BP must be viewed cautiously until further studies can attempt to replicate the result, it lends support to the broader view that neurodevelopmental factors contribute to BP.Journal of Affective Disorders 11/2014; 173.
