Some, but not all, previous studies suggest that prenatal influenza exposure increases the risk of schizophrenia. These used dates epidemics and maternal recall infection to define exposure, suggesting discrepant findings may have resulted from misclassification.To examine whether serologically documented schizophrenia.Nested case-control study a large birth cohort, born 1959 through 1966, followed up for psychiatric disorders 30 38 years later.Population-based cohort.Cases were 64 cohort...

Accumulating evidence suggests that prenatal exposure to infection contributes the etiology of schizophrenia. This line investigation has been advanced by birth cohort studies utilize prospectively acquired data from serologic assays for infectious and immune biomarkers. These investigations have provided further support this hypothesis permitted new pathogens in relation schizophrenia risk. Prenatal infections associated with include rubella, influenza, toxoplasmosis. Maternal cytokines,...

OBJECTIVE: The authors examined the relationship between maternal antibody to toxoplasmosis and risk of schizophrenia other spectrum disorders in offspring. Toxoplasmosis is known adversely affect fetal brain development. METHOD: In a nested case-control design large birth cohort born 1959 1967, conducted serological assays for Toxoplasma on serum specimens from pregnancies giving rise 63 cases 123 matched comparison subjects. immunoglobulin (Ig)G was quantified by using Sabin-Feldman dye...

OBJECTIVE: Many studies have implicated prenatal infection in the etiology of schizophrenia. Cytokines, a family soluble polypeptides, are critically important immune response to and other inflammatory processes. The goal this study was determine whether second-trimester levels four cytokines—interleukin-8 (IL-8), interleukin-1β (IL-1β), interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α)—are higher mothers offspring who later developed schizophrenia spectrum disorders than matched...

Immigrant groups in Western Europe have markedly increased rates of schizophrenia. The highest are found ethnic that predominantly black. Separating minority race/ethnicity from immigration is difficult; the US, these issues can be examined separately. Here we compared schizophrenia between whites and African Americans evaluated whether association was mediated by socioeconomic status (SES) family origin a US birth cohort.Study subjects were offspring women enrolled during pregnancy at...

Gestational influenza has been associated previously with schizophrenia in offspring, but the relationship between this exposure and bipolar disorder (BD) is unclear. The identification of gestational as a risk factor for BD may have potential preventive approaches.To test hypothesis that maternal during pregnancy related to among offspring.Nested case-control study population-based birth cohort from Child Health Development Study (CHDS). From January 1, 1959, through December 31, 1966, CHDS...

Converging evidence suggests that a neurodevelopmental disruption plays role in the vulnerability to schizophrenia. The authors review supporting utero exposure nutritional deficiency as determinant of We first describe studies demonstrating early gestational Dutch Hunger Winter 1944--1945 and severe famine China are each associated with an increased risk schizophrenia offspring. plausibility several candidate micronutrients potential factors for biological mechanisms may underlie these...

We sought to examine the relationship between maternal exposure adult respiratory infections and schizophrenia spectrum disorder (SSD) in Prenatal Determinants of Schizophrenia (PDS) Study, a large birth cohort investigation. Previous work suggests that second trimester infection may be risk factor for SSD. therefore examined whether this class was associated with For purpose, we capitalized on several design advantages PDS including comprehensive, prospective data base physician-diagnosed...

Method: The consisted of 7,794 offspring pregnancies with prospectively acquired data on G/R from obstetric records. diagnosed 71 cases other spectrum disorders cohort. relationship risk was modeled. Results: Exposure during periconceptional period associated a significantly increased disorders, adjustment for race,...
