Abstract
Introduction One of the most common mental disorders in the perinatal period is depression, which is associated with impaired emotional functioning due to alterations in different cognitive aspects including thought and facial emotion recognition. These functional impairment may affect emerging maternal sensitivity and have lasting consequences for the dyadic relationship. The current study aimed to investigate the impact of depressive symptoms on the attention bias of infant stimuli during pregnancy. Methods Eighty-six pregnant women completed the Edinburgh Postnatal Depression Scale and an eye-tracking task comprising infant-related emotion images. All participants showed biased attention to infant-related images. Results First, compared to healthy pregnant women, pregnant women with depression symptoms initially directed their attention to infant-related stimuli more quickly (F (1, 84) = 6.175, p = 0.015, η2 = 0.068). Second, the two groups of pregnant women paid attention to the positive infant stimuli faster than the neutral infant stimuli, and the first fixation latency bias score was significantly smaller than that of the infant-related negative stimulus (p = 0.007). Third, compared with the neutral stimulus, the non-depression group showed a longer first gaze duration to the negative stimulus of infants (p = 0.019), while the depressive symptoms group did not show this difference. Conclusion We speculate that structural and functional changes in affective motivation and cognitive-attention brain areas may induce these attentional bias patterns. These results provide suggestions for the implementation of clinical intervention programs to correct the attention bias of antenatal depressed women.

Abstract
(1) Background: Few studies have explored the heterogeneity of trajectories of stress, anxiety, and depressive symptoms during pregnancy. This study aimed to explore the trajectory groups of stress, anxiety, and depressive symptoms in women during pregnancy and the risk factors associated with those groups. (2) Methods: Data came from pregnant women recruited from January to September 2018 in four hospitals in Chongqing Province, China. A structured questionnaire was given to pregnant women, which collected basic information, including personal, family, and social information. The growth mixture model was applied to identify potential trajectory groups, and multinomial logistic regression was applied to analyze factors of trajectory groups. (3) Results: We identified three stress trajectory groups, three anxiety trajectory groups, and four depression trajectory groups. Less developed regions, inadequate family care, and inadequate social support were associated with a high risk of stress; residence, use of potentially teratogenic drugs, owning pets, family care, and social support were strongly associated with the anxiety trajectory group; family care and social support were the most critical factors for the depression trajectory group. (4) Conclusions: The trajectories of prenatal stress, anxiety, and depressive symptoms are dynamic and heterogeneous. This study may provide some critical insights into the characteristics of women in the high-risk trajectory groups for early intervention to mitigate worsening symptoms.

Abstract
Air pollution may influence prenatal maternal stress, but research evidence is scarce. Using data from a prospective cohort study conducted on pregnant women (n = 2153), we explored the association between air pollution and perceived stress, which was assessed using the 14-item Perceived Stress Scale (PSS), among pregnant women. Average exposures to particulate matter with an aerodynamic diameter of < 2.5 µm (PM2.5) or < 10 µm (PM10), nitrogen dioxide (NO2), and ozone (O3) for each trimester and the entire pregnancy were estimated at maternal residential addresses using land-use regression models. Linear regression models were applied to estimate associations between PSS scores and exposures to each air pollutant. After adjustment for potential confounders, interquartile-range (IQR) increases in whole pregnancy exposures to PM2.5, PM10, and O3 in the third trimester were associated with 0.37 (95% confidence interval [CI] 0.01, 0.74), 0.54 (95% CI 0.11, 0.97), and 0.30 (95% CI 0.07, 0.54) point increases in prenatal PSS scores, respectively. Furthermore, these associations were more evident in women with child-bearing age and a lower level of education. Also, the association between PSS scores and PM10 was stronger in the spring. Our findings support the relationship between air pollution and prenatal maternal stress.

Robust data-driven identification of risk factors and their interactions: A simulation and a study of parental and demographic risk factors for schizophrenia. Int J Methods Psychiatr Res 2020; 29:1-11.

Abstract
OBJECTIVES Few interactions between risk factors for schizophrenia have been replicated, but fitting all such interactions is difficult due to high-dimensionality. Our aims are to examine significant main and interaction effects for schizophrenia and the performance of our approach using simulated data. METHODS We apply the machine learning technique elastic net to a high-dimensional logistic regression model to produce a sparse set of predictors, and then assess the significance of odds ratios (OR) with Bonferroni-corrected p-values and confidence intervals (CI). We introduce a simulation model that resembles a Finnish nested case-control study of schizophrenia which uses national registers to identify cases (n = 1,468) and controls (n = 2,975). The predictors include nine sociodemographic factors and all interactions (31 predictors). RESULTS In the simulation, interactions with OR = 3 and prevalence = 4% were identified with <5% false positive rate and ≥80% power. None of the studied interactions were significantly associated with schizophrenia, but main effects of parental psychosis (OR = 5.2, CI 2.9-9.7; p < .001), urbanicity (1.3, 1.1-1.7; p = .001), and paternal age ≥35 (1.3, 1.004-1.6; p = .04) were significant. CONCLUSIONS We have provided an analytic pipeline for data-driven identification of main and interaction effects in case-control data. We identified highly replicated main effects for schizophrenia, but no interactions.

Abstract
BACKGROUND Prenatal depression has lasting effects on development in offspring, including later mental illness risk. Maternal responses to depression include inflammation and hypothalamic-pituitary-adrenal axis stimulation. Effects on development of cerebral inhibitory neurocircuits may differ for female and male fetuses. METHODS Mothers (N = 181) were assessed periodically, beginning at 16 weeks' gestation, using the Center for Epidemiologic Studies-Depression Scale. Maternal prenatal C-reactive protein and hair cortisol and cortisone levels were determined. Cortisone was determined in neonatal hair. Development of cerebral inhibitory neurocircuits was assessed in 162 1-month-old newborns by inhibition of P50 electrophysiological responses to repeated sounds. RESULTS Maternal depression was associated with decreased newborn P50 inhibition in both sexes. Maternal C-reactive protein levels were significantly associated with depression only in pregnancies with male fetuses and with decreased newborn P50 inhibition only in male newborns. Maternal cortisol levels were significantly associated with depression only in pregnancies with female fetuses and with decreased newborn P50 inhibition only in female newborns. In pregnancies with male fetuses compared with pregnancies with female fetuses, cortisol was more robustly metabolized to cortisone, which does not activate cortisol receptors. CONCLUSIONS This study finds sex-specific associations of C-reactive protein and cortisol levels with prenatal depression in women and with decreased development of newborn P50 inhibition. Sex-based differences in maternal response to depression with inflammation or cortisol and their developmental effects may reflect evolutionary influences to promote survival in adversity. Decreased newborn P50 inhibition is associated with later childhood behavioral problems, and decreased P50 inhibition is a pathophysiological feature of several mental illnesses.

Abstract
BACKGROUND Evidence exists that maternal depression in the perinatal period has an adverse effect on a range of early childhood outcomes and increases the risk of offspring depression during adolescence. However, the association between maternal depression during the perinatal period and offspring psychotic experiences has not been investigated. We aimed to investigate whether there is an association between maternal antenatal or postnatal depression and offspring psychotic experiences at 18 years of age. METHODS This longitudinal study used data from the Avon Longitudinal Study of Parents and Children (ALSPAC), a prospective birth cohort, which recruited 14 541 pregnant women with an estimated delivery date between April 1, 1991, and Dec 31, 1992. Perinatal depression was measured using the Edinburgh Postnatal Depression Scale (EPDS); offspring psychotic experiences at 18 years of age were measured using the Psychosis-Like Symptom Interview. Offspring of mothers with complete data on maternal perinatal depression measures, and complete data on outcome (psychotic experiences) and confounding variables were included in the main analysis. For the main analysis, we used logistic regression to examine the associations between maternal depression (antenatal and postnatal) and offspring psychotic experiences at the age of 18 years. We used biprobit regression to model the association between maternal antenatal depression and the two offspring outcomes (psychotic experiences and depression) at 18 years of age jointly. FINDINGS 3067 offspring for whom data were available on maternal perinatal depression and offspring psychotic experiences aged 18 years were included in analyses. Maternal antenatal depressive symptoms were associated with offspring psychotic experiences at 18 years of age, with an unadjusted odds ratio (OR) of 1·38 (95% CI 1·18-1·61, p=0·0001) and after adjustment for confounders, an OR of 1·26 (1·06-1·49, p=0·0074). Maternal antenatal depressive symptoms were associated with both offspring psychotic experiences at the age of 18 years (n=2830, OR for a 5-point increase in EPDS score: 1·32 [95% CI 1·16-1·51], p<0·0001) and offspring depression at 18 years (OR for a 5-point increase in EPDS score: 1·18 [1·03-1·34], p=0·016). From joint modelling, there was no evidence that the association between maternal antenatal depression and offspring psychotic experiences differed in strength compared with offspring depression (p=0·19). INTERPRETATION The offspring of mothers who experience depression in the perinatal period are more likely to report psychotic experiences at 18 years of age. If the association is found to be causal, it would strengthen the case for identifying and treating maternal depression during and after pregnancy.

Abstract
Objective According to the gene-environment interaction model the pathogenesis of psychosis relies on an adverse neuro-socio-developmental pathway. Perinatal stress represents an important risk factor for the development of psychosis because of the increasingly evident interference with socio-neuro-development in the earlier phases of life. We aim to investigate the correlation of perinatal risk factors with the onset of psychosis with a case–control–incidence study. Results Patients (and their mothers) were eligible if they presented with first-episode psychosis at the Bologna West Community Mental Health Centre (Bo-West CMHC) between 2002 and 2012. The Bo-West CMHC serves a catchment area of about 200,000 people. The controls were recruited in the same catchment area and study period. 42 patients, 26 controls and their mothers were included. We collected the history of peri-natal stress and calculated crude and adjusted Odds Ratios for onset of first-episode psychosis. Adjusted logistic regression showed that psychosis onset was significantly associated with stressful situations during pregnancy, lower level of maternal physical health before or during pregnancy, use of anti-inflammatory drugs during pregnancy, and low level of maternal education. The results of our study suggest that stress during perinatal period increases the risk of developing psychosis.

Abstract
Background: Maternal depression is common during pregnancy, affecting 10-15% of mothers. In previous reports, the offspring of antenatally depressed mothers have had an elevated risk for antisocial, criminal and violent behaviour in adolescence, and for borderline personality features in childhood, but long-term outcomes are unknown.Aims: To study whether the adult offspring of antenatally depressed mothers have an elevated risk for antisocial (ASPD) or borderline personality disorder (BPD) when followed until mid-adulthood.Methods: In the general population-based Northern Finland 1966 Birth Cohort, mothers of 12,058 children were asked during mid-gestation if they felt depressed. Of the mothers, 14% reported being depressed. The offspring were followed for 49 years. The diagnoses of in- and outpatient-treated ASPD and BPD in the offspring were detected using the Finnish Care Register for Healthcare. Maternal antenatal smoking, newborn´s low birthweight or short gestational age, father's social class, and family type at birth were considered as confounding variables. Logistic regression analyses on the potential confounders were performed. Maternal postnatal depression and paternal ASPD information was not available.Results: In the male offspring of antenatally depressed mothers, the risk for ASPD was elevated (adjusted odds ratio 5.6; 95% confidence interval 1.8-17.8), but not in female offspring. The risk for BPD was not elevated in the offspring of antenatally depressed mothers in this study.Conclusions: The sons of antenatally depressed mothers had an increased risk for ASPD. Prevention and treatment of antenatal depression might present an opportunity to decrease the risk of antisocial personality in the offspring.

Early childhood and adolescent risk factors for psychotic depression in a general population birth cohort sample. Soc Psychiatry Psychiatr Epidemiol 2020; 55:1179-1186.

Abstract
BACKGROUND AND PURPOSE In the group of severe mental disorders, psychotic depression (PD) is essentially under-researched. Knowledge about the risk factors is scarce and this applies especially to early risk factors. Our aim was to study early childhood and adolescent risk factors of PD in a representative birth cohort sample with a follow-up of up to 50 years. METHODS The study was carried out using the Northern Finland Birth Cohort 1966 (NFBC 1966). We used non-psychotic depression (NPD) (n = 746), schizophrenia (SZ) (n = 195), psychotic bipolar disorder (PBD) (n = 27), other psychoses (PNOS) (n = 136) and healthy controls (HC) (n = 8200) as comparison groups for PD (n = 58). We analysed several potential early risk factors from time of birth until the age of 16 years. RESULTS The main finding was that parents' psychiatric illness [HR 3.59 (1.84-7.04)] was a risk factor and a high sports grade in school was a protective factor [HR 0.29 (0.11-0.73)] for PD also after adjusting for covariates in the multivariate Cox regression model. Parental psychotic illness was an especially strong risk factor for PD. The PD subjects had a parent with psychiatric illness significantly more often (p < 0.05) than NPD subjects. Differences between PD and other disorder groups were otherwise small. CONCLUSIONS A low sports grade in school may be a risk factor for PD. Psychiatric illnesses, especially psychoses, are common in the parents of PD subjects. A surprisingly low number of statistically significant risk factors may have resulted from the size of the PD sample and the underlying heterogeneity of the etiology of PD.

Abstract
Background: Psychiatric disorders tend to be developmental, and longitudinal settings are required to examine predictors of psychiatric phenomena. Replicating and combining data and results from different birth cohorts, which are a source of reliable data, can make research even more valuable. The Finnish Psychiatric Birth Cohort Consortium (PSYCOHORTS) project combines birth cohorts in Finland. Aim: The aim of this paper is to introduce content, plans and perspectives of the PSYCOHORTS project that brings together researchers from Finland. In addition, we illustrate an example of data harmonization using available data on causes of death. Content: PSYCOHORTS includes eight Finnish birth cohorts. The project has several plans: to harmonize different data from birth cohorts, to incorporate biobanks into psychiatric birth cohort research, to apply multigenerational perspectives, to integrate longitudinal patterns of marginalization and inequality in mental health, and to utilize data in health economics research. Data on causes of death, originally obtained from Finnish Cause of Death register, were harmonized across the six birth cohorts using SAS macro facility. Results: Harmonization of the cause of death data resulted in a total of 21,993 observations from 1965 to 2015. For example, the percentage of deaths due to suicide and the sequelae of intentional self-harm was 14% and alcohol-related diseases, including accidental poisoning by alcohol, was 13%. Conclusions: PSYCOHORTS lays the foundation for complex examinations of psychiatric disorders that is based on compatible datasets, use of biobanks and multigenerational approach to risk factors, and extensive data on marginalization and inequality.

Abstract
BACKGROUND Prenatal mental disorders are associated with maternal and fetal adverse outcomes, while few studies have been performed in mainland China. This study aimed to investigate the prevalence and influencing factors of maternal stress, anxiety and depression in early pregnancy and provide scientific basis for reducing prenatal mental disorders. METHODS Data were obtained from 1220 women with < 15 weeks gestation in a cohort study conducted in Chongqing, China. Prenatal stress, anxiety and depression were assessed using the pregnancy pressure scale, the Hamilton anxiety scale, and the self-rating depression scale, respectively. RESULTS The prevalence of prenatal stress, anxiety and depression in early pregnancy was 91.86%, 15.04% and 5.19%, respectively. Logistic regression analysis revealed that the risk factors for prenatal stress include housewife/unemployment, presence of anxiety and low- and moderate-level social support, besides, the protective factors were exercise, active smoking and no suggestion from parents. Housewife/unemployment, primiparity, presence of stress and depression and low-level social support were found to be associated with the development of anxiety symptoms, whereas exercise had a protective effect on it. Group-oriented personality, presence of anxiety, no suggestion from husband, low- and moderate-level family care, and low-level social support were risk factors for prenatal depression. LIMITATIONS All participants were recruited from one region of China, and none of them have a history of cesarean section. CONCLUSION Early screening and intervention may have great significance for reducing mental disorders of pregnant women, and the family and society support should be brought into the intervention as well.

Abstract
BACKGROUND Maternal antenatal depression may alter offspring neurodevelopment, but long follow-up studies are lacking. We studied the risks for mood disorders and schizophrenia in adult offspring of antenatally depressed mothers, taking account parental severe mental disorders. METHODS In the general population-based Northern Finland 1966 Birth Cohort with 12,058 children, 13.9% of the mothers reported themselves depressed at mid-gestation. The offspring were followed 43 years. Severe mood disorders and schizophrenia in the offspring and severe mental disorders in the parents were detected using the Care Register for Healthcare. Maternal smoking during pregnancy, perinatal complications, fathers´ social class, family type at birth, and grand multiparity were considered as confounding variables. RESULTS The offspring of antenatally depressed mothers had an elevated risk for depression (adjusted OR 1.5; 95% CI 1.03-2.2), compared to cohort members without maternal antenatal depressed mood. The offspring with maternal antenatal depressed mood and parental severe mental disorder had markedly elevated risks for depression (3.3; 1.8-6.2), and schizophrenia (3.9; 2.0-7.5), compared to the offspring without one or both of these risk factors. LIMITATIONS Maternal antenatal depressed mood was determined by one question and did not necessarily signify a clinical condition. Data on maternal postnatal mood was not available. CONCLUSION The offspring with maternal antenatal depressed mood and parental severe mental disorder had high risk for depression and schizophrenia. Early interventions in parental severe mental disorder might present an opportunity for decreasing the risk for mood disorders and schizophrenia in the offspring.

Abstract
Maternal stress and medical illnesses during early life are well-documented environmental indicators of an increased risk of schizophrenia. Few studies, conversely, have confirmed an association with major affective disorders. The present study examined the impact of maternal stress, medical illnesses and obstetric complications on the development of severe mental disorder in 240 patients with a diagnosis of schizophrenia spectrum disorder, bipolar disorder, or major depressive disorder and matched with 85 controls. Mothers of participants were asked about stressful events during pregnancy using the Social Readjustment Scale; information on prenatal/perinatal illnesses were acquired from medical records. Schizophrenia spectrum disorder was positively associated with maternal stress (OR = 2.16), infections (OR = 7.67), inadequate weight gain (OR = 9.52) during pregnancy, and peripartum asphyxia (OR = 4.00). An increased risk of bipolar disorder was associated with head circumference < 32 cm at birth (OR = 5.40) and inversely with inadequate weight gain (OR = 0.29). Major depressive disorder diagnosis was inversely related to inadequate weight gain (OR = 0.22). These results support a role for maternal stress, medical illnesses and obstetric complications as risk factors for subsequent severe mental illness in adulthood. Further research is needed, especially with regard to affective disorders.

Abstract
AIM To find factors that are associated with not having psychotic illness in a prospective general population sample, with a special interest in individuals with parental psychosis. METHODS Data from the Northern Finland Birth Cohort 1966 (n = 10 458) and several registers were used to detect individuals with and without parental psychosis. Altogether, 594 persons had parent(s) with psychosis and 48 of them also had psychosis subsequently. Variables related to pregnancy and birth, family and childhood, health and habits in adolescence, school performance and physical activity were studied to identify determinants of unaffected status among individuals with and without parental psychosis. RESULTS In the parental psychosis group, the unaffected persons had more likely a mother who was non-depressed during pregnancy, and who worked outside the home or studied than among those who developed psychosis. CONCLUSIONS Protective factors for psychosis were surprisingly few in this sample. These factors were related to the mother's non-depressed mood and the mother's work outside the home or studies. This could relate to better health and functioning of a mother. This work highlights the need for more research on protective factors for psychosis in order to identify methods for prevention of psychosis.

Abstract
Schizophrenia and other types of psychosis incur suffering, high health care costs and loss of human potential, due to the combination of early onset and poor response to treatment. Our ability to prevent or cure psychosis depends on knowledge of causal mechanisms. Molecular genetic studies show that thousands of common and rare variants contribute to the genetic risk for psychosis. Epidemiological studies have identified many environmental factors associated with increased risk of psychosis. However, no single genetic or environmental factor is sufficient to cause psychosis on its own. The risk of developing psychosis increases with the accumulation of many genetic risk variants and exposures to multiple adverse environmental factors. Additionally, the impact of environmental exposures likely depends on genetic factors, through gene-environment interactions. Only a few specific gene-environment combinations that lead to increased risk of psychosis have been identified to date. An example of replicable gene-environment interaction is a common polymorphism in the AKT1 gene that makes its carriers sensitive to developing psychosis with regular cannabis use. A synthesis of results from twin studies, molecular genetics, and epidemiological research outlines the many genetic and environmental factors contributing to psychosis. The interplay between these factors needs to be considered to draw a complete picture of etiology. To reach a more complete explanation of psychosis that can inform preventive strategies, future research should focus on longitudinal assessments of multiple environmental exposures within large, genotyped cohorts beginning early in life.

Abstract
Genes, infection, malnutrition, and other factors affecting fetal brain development are a major component of risk for a child's emotional development and later mental illnesses, including schizophrenia, bipolar disorder, and autism. Prenatal interventions to ameliorate that risk have yet to be established for clinical use. A systematic review of prenatal nutrients and childhood emotional development and later mental illness was performed. Randomized trials of folic acid, phosphatidylcholine, and omega-3 fatty acid supplements assess effects of doses beyond those adequate to remedy deficiencies to promote normal fetal development despite genetic and environmental risks. Folic acid to prevent neural tube defects is an example. Vitamins A and D are currently recommended at maximum levels, but women's incomplete compliance permits observational studies of their effects. Folic acid and phosphatidylcholine supplements have shown evidence for improving childhood emotional development associated with later mental illnesses. Vitamins A and D decreased the risk for schizophrenia and autism in retrospective observations. Omega-3 fatty acid supplementation during early pregnancy increased the risk for schizophrenia and increased symptoms of attention deficit hyperactivity disorder, but in later pregnancy it decreased childhood wheezing and premature birth. Studies are complicated by the length of time between birth and the emergence of mental illnesses like schizophrenia, compared with anomalies like facial clefts identified at birth. As part of comprehensive maternal and fetal care, prenatal nutrient interventions should be further considered as uniquely effective first steps in decreasing risk for future psychiatric and other illnesses in newborn children.

A comparison of the cumulative incidence and early risk factors for psychotic disorder in young adults in the Northern Finland Birth Cohorts 1966 and 1986. Epidemiol Psychiatr Sci 2017; 26:314-324.

Abstract
AIMS Few studies have compared time trends for the incidence of psychosis. To date, the results have been inconsistent, showing a decline, an increase or no significant change. As far as we know, no studies explored changes in prevalence of early risk factors. The aim of this study was to investigate differences in early risk factors and cumulative incidences of psychosis by type of psychosis in two comparable birth cohorts. METHODS The Northern Finland Birth cohorts (NFBCs) 1966 (N = 12 058) and 1986 (N = 9432) are prospective general population-based cohorts with the children followed since mother's mid-pregnancy. The data for psychoses, i.e. schizophrenia (narrow, spectrum), bipolar disorder with psychotic features, major depressive episode with psychotic features, brief psychosis and other psychoses (ICD 8-10) were collected from nationwide registers including both inpatients and outpatients. The data on early risk factors including sex and place of birth of the offspring, parental age and psychosis, maternal education at birth were prospectively collected from the population registers. The follow-up reached until the age of 27 years. RESULTS An increase in the cumulative incidence of all psychoses was seen (1.01% in NFBC 1966 v. 1.90% in NFBC 1986; p < 0.001), which was due to an increase in diagnosed affective and other psychoses. Earlier onset of cases and relatively more psychoses in women were observed in the NFBC 1986. Changes in prevalence of potential early risk factors were identified, but only parental psychosis was a significant predictor in both cohorts (hazard ratios ≥3.0; 95% CI 1.86-4.88). The difference in psychosis incidence was not dependent on changes in prevalence of studied early risk factors. CONCLUSIONS Surprisingly, increase in the cumulative incidence of psychosis and also changes in the types of psychoses were found between two birth cohorts 20 years apart. The observed differences could be due to real changes in incidence or they can be attributable to changes in diagnostic practices, or to early psychosis detection and treatment.

Abstract
BACKGROUND Maternal depression is relatively common during pregnancy. However, follow-ups of the adult offspring of antenatally depressed mothers are scarce. Previously we found the risk of schizophrenia to be higher in the adult offspring with antenatally depressed mothers and parents with psychosis than in subjects with only one or neither of these risk factors. The aim was to study whether the risk of schizotypal or affective traits differ among adult offspring with antenatally depressed mothers with or without a parental history of psychosis when compared with offspring without antenatally depressed mothers and without parental psychosis. METHODS In the general population-based Northern Finland 1966 Birth Cohort (NFBC 1966), the mothers of the cohort members were asked at mid-gestation whether they felt depressed. Parental psychosis (Familial Risk, FR) was detected using the Finnish Care Register for Health Care. In the 31-year field study, seven psychometric questionnaires surveyed schizotypal and affective traits in the offspring. The final sample included 4928 individuals (2203 males). RESULTS There were no statistically significant differences in mean scores on the schizotypal and affective scales between offspring with and without antenatally depressed mothers, or between subjects with and without parental psychosis. The scores were not highest in the subjects with both maternal antenatal depressed mood and FR. CONCLUSION Surprisingly, maternal depressed mood during pregnancy was unlikely to increase the risk of schizotypy or affective traits in adult offspring, and not even with parental psychosis (FR) in this general population-based birth cohort with about 5000 subjects.

Abstract
BACKGROUND We examined mortality in schizophrenia spectrum disorder (SSD) and non-schizophrenic psychosis (NSSD) compared to individuals without psychosis, and whether perinatal factors predict mortality. METHODS Within Northern Finland Birth Cohort 1966 (n=10 933; 203 with SSD, 178 with NSSD), mortality was followed until end of 2011 by national register. Wantedness of pregnancy, mother's antenatal depression, smoking and age, parity, paternal socio-economic status (SES) and family type at birth were examined as predictors of mortality. RESULTS Mortality was higher in SSD (hazard ratio (HR) 3.60; 95% confidence interval (CI) 2.38-5.45) and NSSD (4.05; 2.65-6.17) compared to persons without psychoses after adjustment for gender. HR for natural death was 2.01 (0.82-4.91) in SSD and 4.63 (2.43-8.80) in NSSD after adjustment for gender. Corresponding figures for unnatural deaths were 4.71 (2.94-7.54) and 2.94 (1.56-5.55), respectively. Among non-psychotic persons, mother's depression, smoking and low SES predicted mortality after adjustment for gender and parental psychoses (and SES), whereas among psychosis those whose father was a farmer had lower risk of mortality compared to those with high SES. CONCLUSIONS Individuals with SSD had a higher risk of unnatural death and individuals with NSSD of natural and unnatural deaths. Perinatal factors seem to be more important predictors of mortality in individuals without psychoses than with psychoses. According to population-based long follow-up data, it is important to pay attention to somatic morbidity behind natural causes of death in psychoses and to prevent suicides in order to prevent excess mortality.

A systematic review of evidence from prospective studies for developmental risk factors and antecedents of the schizophrenia spectrum disorders and affective psychoses. BMC Psychiatry 2015; 15:205. [PMID: 26302744 PMCID: PMC4548447 DOI: 10.1186/s12888-015-0562-2] [Citation(s) in RCA: 80] [Impact Index Per Article: 8.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/21/2015] [Accepted: 07/14/2015] [Indexed: 01/28/2023] Open
Abstract
BACKGROUND Identifying the unique and shared premorbid indicators of risk for the schizophrenia spectrum disorders (SSD) and affective psychoses (AP) may refine aetiological hypotheses and inform the delivery of universal versus targeted preventive interventions. This systematic review synthesises the available evidence concerning developmental risk factors and antecedents of SSD and AP to identify those with the most robust support, and to highlight remaining evidence gaps. METHODS A systematic search of prospective birth, population, high-risk, and case-control cohorts was conducted in Medline and supplemented by hand searching, incorporating published studies in English with full text available. Inclusion/exclusion decisions and data extraction were completed in duplicate. Exposures included three categories of risk factors and four categories of antecedents, with case and comparison groups defined by adult psychiatric diagnosis. Effect sizes and prevalence rates were extracted, where available, and the strength of evidence synthesised and evaluated qualitatively across the study designs. RESULTS Of 1775 studies identified by the search, 127 provided data to the review. Individuals who develop SSD experience a diversity of subtle premorbid developmental deficits and risk exposures, spanning the prenatal period through early adolescence. Those of greatest magnitude (or observed most consistently) included obstetric complications, maternal illness during pregnancy (especially infections), other maternal physical factors, negative family emotional environment, psychopathology and psychotic symptoms, and cognitive and motor dysfunctions. Relatively less evidence has accumulated to implicate this diversity of exposures in AP, and many yet remain unexamined, with the most consistent or strongest evidence to date being for obstetric complications, psychopathology, cognitive indicators and motor dysfunction. Among the few investigations affording direct comparison between SSD and AP, larger effect sizes and a greater number of significant associations are commonly reported for SSD relative to AP. CONCLUSIONS Shared risk factors for SSD and AP may include obstetric complications, childhood psychopathology, cognitive markers and motor dysfunction, but the capacity to distinguish common versus distinct risk factors/antecedents for SSD and AP is limited by the scant availability of prospective data for AP, and inconsistency in replication. Further studies considering both diagnoses concurrently are needed. Nonetheless, the prevalence of the risk factors/antecedents observed in cases and controls helps demarcate potential targets for preventative interventions for these disorders.

Abstract
Schizophrenia is a disease of abnormal brain development. Considerable evidence now indicates that environmental factors have a causative role in schizophrenia. Elevated incidence of the disease has been linked to a wide range of disturbances in the prenatal environment and to social factors and drug intake during adolescence. Here we examine neurodevelopment of the prefrontal cortex in the first trimester of gestation and during adolescence to gain further insight into the neurodevelopmental processes that may be vulnerable in schizophrenia. Early embryonic development of the prefrontal cortex is characterized by cell proliferation, including renewal of progenitor cells, generation of early transient cell populations and neurogenesis of subcortical populations. Animal models show that curtailing early gestational cell proliferation produces schizophrenia-like pathology in the prefrontal cortex and mimics key behavioral and cognitive symptoms of the disease. At the other end of the spectrum, elimination of excitatory synapses is the fundamental process occurring during adolescent maturation in the prefrontal cortex. Adverse social situations that elevate stress increase dopamine stimulation of the mesocortical pathway and may lead to exaggerated synaptic pruning during adolescence. In a non-human primate model, dopamine hyperstimulation has been shown to decrease prefrontal pyramidal cell spine density and to be associated with profound cognitive dysfunction. Development of the prefrontal cortex in its earliest stage in gestation and in its final stage in adolescence represents two critical periods of vulnerability for schizophrenia in which cell proliferation and synaptic elimination, respectively, may be influenced by environmental factors.

Abstract
Endophenotypes are disease-associated phenotypes that are thought to reflect the neurobiological or other mechanisms that underlie the more overt symptoms of a psychiatric illness. Endophenotypes have been critical in understanding the genetics, neurobiology, and treatment of schizophrenia. Because psychiatric illnesses have multiple causes, including both genetic and nongenetic risk factors, an endophenotype linked to one of the mechanisms may be expressed more frequently than the disease itself. However, in schizophrenia research, endophenotypes have almost exclusively been studied in older adolescents or adults who have entered or passed through the age of risk for the disorder. Yet, schizophrenia is a neurodevelopmental disorder where prenatal development starts a cascade of brain changes across the lifespan. Endophenotypes have only minimally been utilized to explore the perinatal development of vulnerability. One major impediment to the development of perinatally-useful endophenotypes has been the established validity criteria. For example, the criterion that the endophenotype be more frequently present in those with disease than those without is difficult to demonstrate when there can be a decades-long period between endophenotype measurement and the age of greatest risk for onset of the disorder. This article proposes changes to the endophenotype validity criteria appropriate to perinatal research and reviews how application of these modified criteria helped identify a perinatally-usable phenotype of risk for schizophrenia, P50 sensory gating, which was then used to propose a novel perinatal primary prevention intervention.

Abstract
Background The primary prevention of illness at the population level, the ultimate aim
of medicine, seems out of reach for schizophrenia. Schizophrenia has a
strong genetic component, and its pathogenesis begins long before the
emergence of psychosis, as early as fetal brain development. Cholinergic
neurotransmission at nicotinic receptors is a pathophysiological mechanism
related to one aspect of this genetic risk. Choline activates these
nicotinic receptors during fetal brain development. Dietary supplementation
of maternal choline thus emerges as a possible intervention in pregnancy to
alter the earliest developmental course of the illness. Aim Review available literature on the relationship of choline supplementation or
choline levels during pregnancy and fetal brain development. Methods A Medline search was used to identify studies assessing effects of choline in
human fetal development. Studies of other prenatal risk factors for
schizophrenia and the role of cholinergic neurotransmission in its
pathophysiology were also identified. Results Dietary requirements for choline are high during pregnancy because of its
several uses, including membrane biosynthesis, one-carbon metabolism, and
cholinergic neurotransmission. Its ability to act directly at high
concentrations as a nicotinic agonist is critical for normal brain circuit
development. Dietary supplementation in the second and third trimesters with
phosphatidyl-choline supports these functions and is associated generally
with better fetal outcome. Improvement in inhibitory neuronal functions
whose deficit is associated with schizophrenia and attention deficit
disorder has been observed. Conclusion Prenatal dietary supplementation with phosphatidyl-choline and promotion of
diets rich in choline-containing foods (meats, soybeans, and eggs) are
possible interventions to promote fetal brain development and thereby
decrease the risk of subsequent mental illnesses. The low risk and short
(sixmonth) duration of the intervention makes it especially conducive to
population-wide adoption. Similar findings with folate for the prevention of
cleft palate led to recommendations for prenatal pharmacological
supplementation and dietary improvement. However, definitive proof of the
efficacy of prenatal choline supplementation will not be available for
decades (because of the 20-year lag until the onset of schizophrenia), so
public health officials need to decide whether or not promoting choline
supplementation is justified based on the limited information available.

Abstract
Background Delayed motor development in infancy and family history of psychosis are both associated with increased risk of schizophrenia, but their interaction is largely unstudied. Aim To investigate the association of the age of achieving motor milestones and parental psychosis and their interaction in respect to risk of schizophrenia. Methods We used data from the general population-based prospective Northern Finland Birth Cohort 1966 (n = 10,283). Developmental information of the cohort members was gathered during regular visits to Finnish child welfare clinics. Several registers were used to determine the diagnosis of schizophrenia among the cohort members and psychosis among the parents. Altogether 152 (1.5%) individuals had schizophrenia by the age of 46 years, with 23 (15.1%) of them having a parent with psychosis. Cox regression analysis was used in analyses. Results Parental psychosis was associated (P < 0.05) with later achievement of holding the head up, grabbing an object, and walking without support. In the parental psychosis group, the risk for schizophrenia was increased if holding the head up (hazard ratio [HR]: 2.46; degrees of freedom [df] = 1; 95% confidence interval [95% CI]: 1.07–5.66) and touching the thumb with the index finger (HR: 1.84; df = 1; 95% CI: 1.11–3.06) was later. In the group without parental psychosis, a delay in the following milestones increased the risk of schizophrenia: standing without support and walking without support. Parental psychosis had an interaction with delayed touching thumb with index finger (HR: 1.87; df = 1; 95% CI: 1.08–3.25) when risk of schizophrenia was investigated. Conclusions Parental psychosis was associated with achieving motor milestones later in infancy, particularly the milestones that appear early in a child's life. Parental psychosis and touching the thumb with the index finger had a significant interaction on risk of schizophrenia. Genetic risk for psychosis may interact with delayed development to raise future risk of schizophrenia, or delayed development may be a marker of other risk processes that interact with genetic liability to cause later schizophrenia.

Abstract
We investigated the relationship between sibling characteristics (birth order, number of siblings and birth interval) and early onset psychosis among adolescent psychiatric inpatients and their mentally healthy controls. A short birth interval of 1-2 years to the nearest sibling was more common among adolescents with schizophrenia and schizophrenia spectrum psychoses and differed significantly from healthy controls (p = 0.037). A large family (at least 6 children in family) was more common among adolescents with psychosis NOS than among healthy controls (p = 0.035). The birth order among young adolescents with any subtype of psychosis did not differ from healthy controls. Sibling characteristics may be contributing factors in the multifactorial aetiology of schizophrenia and other psychotic disorders. Further studies are required to determine whether sibling characteristics reflect other unknown environmental factors.

Abstract
Many studies have demonstrated that genotype (G) interacts with adverse life experiences (E) to produce individual differences in vulnerability and resilience to mental disorders, including schizophrenia. Genetic susceptibility to stress and the timing of the environmental exposure(s) are relevant for these interactions and represent common risk factors. We take the example of the FKBP5 gene to illustrate G × E interactions that predict pleiotropic psychiatric outcomes, including schizophrenia.

Twenty Years of Schizophrenia Research in the Northern Finland Birth Cohort 1966: A Systematic Review. SCHIZOPHRENIA RESEARCH AND TREATMENT 2015; 2015:524875. [PMID: 26090224 PMCID: PMC4452001 DOI: 10.1155/2015/524875] [Citation(s) in RCA: 21] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 01/11/2015] [Revised: 04/24/2015] [Accepted: 04/29/2015] [Indexed: 11/17/2022]
Abstract
Birth cohort designs are useful in studying adult disease trajectories and outcomes, such as schizophrenia. We review the schizophrenia research performed in the Northern Finland Birth Cohort 1966 (NFBC 1966), which includes 10,934 individuals living in Finland at 16 years of age who have been monitored since each mother's mid-pregnancy. By the age of 44, 150 (1.4%) had developed schizophrenia. There are 77 original papers on schizophrenia published from the NFBC 1966. The early studies have found various risk factors for schizophrenia, especially related to pregnancy and perinatal phase. Psychiatric and somatic outcomes were heterogeneous, but relatively poor. Mortality in schizophrenia is high, especially due to suicides. Several early predictors of outcomes have also been found. Individuals with schizophrenia have alterations in brain morphometry and neurocognition, and our latest studies have found that the use of high lifetime doses of antipsychotics associated with these changes. The schizophrenia research in the NFBC 1966 has been especially active for 20 years, the prospective study design and long follow-up enabling several clinically and epidemiologically important findings. When compared to other birth cohorts, the research in the NFBC 1966 has offered also unique findings on course and outcome of schizophrenia.

Abstract
AIM To provide scientific evidence, using a literature review on psychosocial risk factors in mental health, that a high exposure to psychosocial stress situations in childhood increases the risk of mental disorders in adulthood,. DESIGN A literature review up to December 2011 in the electronic databases from Medline, Universitat de Barcelona, and the Universitat Autonoma de Barcelona. The keywords used were: childhood, prenatal, vulnerability, risk, abuse, neglect, child mental disorder, schizophrenia, and prevention. Inclusion criteria for the studies reviewed: 1) designed to investigate childhood risk factors; 2) Comparative studies with persons without risk factors; 3) Studies with sufficient statistical significance; 4) Studies with "n" participants equal to o more than 30 persons. RESULTS There are a group of easily identifiable mental health risk factors in childhood that can help in the prevention of mental disorders in the adulthood. They can be grouped into four categories: A) Pregnancy, birth and perinatal problems; B) Poor interpersonal relations with parents; C) Adverse life events in the first two years of life; D) Cognitive deficits in primary school, and social isolation during school years. CONCLUSIONS There are life events that may increase the possibilities of suffering some kind of Psychopathology. It is necessary to consider those events as Risk Factors for Mental Health. The accumulation of these Risk Factors increases vulnerability to Mental Disorders.

Abstract
Prenatal stress is a risk factor for several psychiatric disorders in which inhibitory neuron pathology is implicated. A growing body of research demonstrates that inhibitory circuitry in the brain is directly and persistently affected by prenatal stress. This review synthesizes research that explores how this early developmental risk factor impacts inhibitory neurons and how these findings intersect with research on risk factors and inhibitory neuron pathophysiology in schizophrenia, anxiety, autism and Tourette syndrome. The specific impact of prenatal stress on inhibitory neurons, particularly developmental mechanisms, may elucidate further the pathophysiology of these disorders.

Interaction between parental psychosis and risk factors during pregnancy and birth for schizophrenia - the Northern Finland 1966 Birth Cohort study. Schizophr Res 2013; 145:56-62. [PMID: 23375940 DOI: 10.1016/j.schres.2012.12.033] [Citation(s) in RCA: 21] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/29/2012] [Revised: 11/16/2012] [Accepted: 12/17/2012] [Indexed: 02/04/2023]
Abstract
Our aim was to investigate the association between parental psychosis and potential risk factors for schizophrenia and their interaction. We evaluated whether the factors during pregnancy and birth have a different effect among subjects with and without a history of parental psychosis and whether parental psychosis may even explain their effects on the risk of schizophrenia. The sample comprised 10,526 individuals from the Northern Finland 1966 Birth Cohort. A total of 150 (1.4%) cohort members had schizophrenia by the age of 44 years, of them 18 (12.0%) had a parent with a history of psychosis. In non-psychotic cohort members, this figure was 495 (4.8%). In the parental psychosis group, significant early biological risk factors for schizophrenia included high birth weight (hazard ratio, HR 11.4; 95% confidence interval 3.3-39.7) and length (HR 4.1; 1.3-12.5), high birth weight in relation to gestational age (HR 3.2; 1.1-9.0), and high maternal age (HR 2.6.; 1.0-6.7). High birth weight and length and high maternal education had a significant interaction with parental psychosis. The presence of any biological risk factor increased the risk of schizophrenia significantly only among the parental psychosis group (HR 4.0; 1.5-10.5), whereas the presence of any psychosocial risk factor had no interaction with parental psychosis. Parental psychosis can act as an effect modifier on early risk factors for schizophrenia. Evaluation of the mechanisms behind the risk factors should, therefore, include consideration of the parental history of psychosis.

Abstract
PURPOSE OF REVIEW To systematize existing data and review new findings on the cause of schizophrenia and outline an improved mixed model of schizophrenia risk. RECENT FINDINGS Multiple and variable genetic and environmental factors interact to influence the risk of schizophrenia. Both rare variants with large effect and common variants with small effect contribute to genetic risk of schizophrenia, with no indication for differential impact on its clinical features. Accumulating evidence supports a genetic architecture of schizophrenia with multiple scenarios, including additive polygenic, heterogeneity, and mixed polygenic-heterogeneity. The epigenetic mechanisms that mediate gene-environment (GxE) interactions provide a framework to incorporate environmental factors into models of schizophrenia risk. Environmental pathogens with small effect on risk have robust effects in the context of family history of schizophrenia. Hence, genetic risk for schizophrenia may be expressed in part as sensitivity to environmental factors. SUMMARY We propose an improved mixed model of schizophrenia risk in which abnormal epigenetic states with large effects are superimposed on a polygenic liability to schizophrenia. This scenario can account for GxE interactions and shared family environment, which in many cases are not explained by a single structural variant of large effect superimposed on polygenes (the traditional mixed model).

Abstract
OBJECTIVE Deficient cerebral inhibition is a pathophysiological brain deficit related to poor sensory gating and attention in schizophrenia and other disorders. Cerebral inhibition develops perinatally, influenced by genetic and in utero factors. Amniotic choline activates fetal α7-nicotinic acetylcholine receptors and facilitates development of cerebral inhibition. Increasing this activation may protect infants from future illness by promoting normal brain development. The authors investigated the effects of perinatal choline supplementation on the development of cerebral inhibition in human infants. METHOD A randomized placebo-controlled clinical trial of dietary phosphatidylcholine supplementation was conducted with 100 healthy pregnant women, starting in the second trimester. Supplementation to twice normal dietary levels for mother or newborn continued through the third postnatal month. All women received dietary advice regardless of treatment. Infants' electrophysiological recordings of inhibition of the P50 component of the cerebral evoked response to paired sounds were analyzed. The criterion for inhibition was suppression of the amplitude of the second P50 response by at least half, compared with the first response. RESULTS No adverse effects of choline were observed in maternal health and delivery, birth, or infant development. At the fifth postnatal week, the P50 response was suppressed in more choline-treated infants (76%) compared with placebo-treated infants (43%) (effect size=0.7). There was no difference at the 13th week. A CHRNA7 genotype associated with schizophrenia was correlated with diminished P50 inhibition in the placebo-treated infants, but not in the choline-treated infants. CONCLUSIONS Neonatal developmental delay in inhibition is associated with attentional problems as the child matures. Perinatal choline activates timely development of cerebral inhibition, even in the presence of gene mutations that otherwise delay it.

Abstract
BACKGROUND Temporomandibular disorders (TMDs) are clinical problems involving the masticatory muscles and temporomandibular joints (TMJs). Aspects of the aetiology of TMD are controversial. Many studies have identified an association between depression and TMD. The aim of the study was to evaluate the association between both maternal antenatal depression and parental depression during the offspring's childhood with TMD symptoms of the offspring during adulthood and to evaluate the effect of the offspring's own depression on this association. METHODS In the general population-based Northern Finland Birth Cohort 1966 (NFBC 1966), mothers of 12,058 children were asked at mid-gestation at the antenatal clinic if they felt depressed. Of these offspring who had data available on TMD symptoms in the computer-aided inquiry at the 31-year field study, a final study data of 5541 subjects was compiled. The Finnish Hospital Discharge Register was used to identify depression in the parents between the years 1972 and 1984 (when offspring were 6-18 years old). RESULTS There were no statistically significant associations between TMD symptoms and maternal antenatal depressed mood. However, parental depression during the offspring's childhood associated significantly with facial pain [adjusted odds ratio (OR) = 1.64; 1.05-2.56] and with TMJ pain at jaw rest (OR = 1.81; 1.13-2.89), even after adjusting for gender, occupation of the father, family type at birth and the offspring's self-reported depression in adulthood. CONCLUSION The risk for TMD symptoms is not elevated in the offspring of antenatally depressed mothers. Parental depression during an offspring's childhood increases the risk of pain-related TMD symptoms in their early adulthood.

Abstract
PURPOSE To investigate those ante- and perinatal circumstances preceding suicide attempts and suicides, which have so far not been studied intensively. METHODS Examination of the Northern Finland Birth Cohort 1966 (n = 10,742), originally based on antenatal questionnaire data and now followed up from mid-pregnancy to age 39, to ascertain psychiatric disorders in the parents and offspring and suicides or attempted suicides in the offspring using nationwide registers. RESULTS A total of 121 suicide attempts (57 males) and 69 suicides (56 males) had occurred. Previously unstudied antenatal factors (maternal depressed mood and smoking, unwanted pregnancy) were not related to these after adjustment. Psychiatric disorders in the parents and offspring were the risk factors in both genders. When adjusted for these, the statistically significant risk factors among males were a single-parent family for suicide attempts (OR 3.71, 95% CI 1.62-8.50) and grand multiparity for suicides (OR 2.67, 95% CI 1.15-6.18). When a psychiatric disorder in females was included among possible risk factors for suicide attempts, it alone remained significant (OR 15.55, 8.78-27.53). CONCLUSIONS A single-parent family was a risk factor for attempted suicides and grand multiparity for suicides in male offspring even after adjusting for other ante- and perinatal circumstances and mental disorders in the parents and offspring. Mothers' antenatal depressed mood and smoking and unwanted pregnancy did not increase the risk of suicide, which is a novel finding.

Abstract
Taking a developmental psychopathology perspective, our objective was to identify ways in which psychosocial treatment of depression during pregnancy may be enhanced. We first consider the state of evidence on psychosocial interventions for antenatal depression, next define key developmental psychopathology concepts that are relevant to antenatal depression, and finally discuss implications for clinical practice and research. We found a limited, but promising, evidence base for effective psychosocial interventions for depression during pregnancy. Examining antenatal depression from a developmental psychopathology perspective revealed suggestions for improving treatment. A developmental psychopathology perspective suggests that treatment of depression during pregnancy may be improved by attention to the continuum of depression, from subclinical to severe major depressive disorder; personalized care based on individual women's pattern of risk and resilience factors and correlated risks; consideration of the potential benefits of treating the couple's relationship, the mother's qualities of parenting, and infants' and children's mental health needs; and, including a detailed understanding of the developmental pathways to antenatal depression for each patient in treatment planning.

Abstract
Schizophrenia is a psychiatric disorder that includes symptoms such as hallucinations, disordered thoughts, disorganized or catatonic behaviour, cognitive dysfunction and sleep-wake disturbance. In addition to these symptoms, cardiometabolic dysfunction is common in patients with schizophrenia. While previously it has been thought that cardiometabolic symptoms in patients with schizophrenia were associated with medications used to manage this disorder, more recently it has been demonstrated that these symptoms are present in drug naive and unmedicated patients. Sleep-wake disturbance, resulting in chronic sleep loss has also been demonstrated to induce changes in cardiometabolic function. Chronic sleep loss has been associated with an increased risk for weight gain, obesity and cardiac and metabolic disorders, independent of other potentially contributing factors, such as smoking and body mass index. We hypothesise that the sleep-wake disturbance comorbid with schizophrenia may play a significant role in the high prevalence of cardiometabolic dysfunction observed in this patient population. Here we present a critical review of the evidence that supports this hypothesis.

Abstract
Abstract
In this article, we study the effects of prenatal health on educational attainment and on the reproduction of family background inequalities in education. Using Finnish birth cohort data, we analyze several maternal and fetal health variables, many of which have not been featured in the literature on long-term socioeconomic effects of health despite the effects of these variables on birth and short-term health outcomes. We find strong negative effects of mother’s prenatal smoking on educational attainment, which are stronger if the mother smoked heavily but are not significant if she quit during the first trimester. Anemia during pregnancy is also associated with lower levels of attained education. Other indicators of prenatal health (pre-pregnancy obesity, mother’s antenatal depressed mood, hypertension and preeclampsia, early prenatal care visits, premature birth, and small size for gestational age) do not predict educational attainment. Our measures explain little of the educational inequalities by parents’ class or education. However, smoking explains 12%—and all health variables together, 19%—of the lower educational attainment of children born to unmarried mothers. Our findings point to the usefulness of proximate health measures in addition to general ones. They also point to the potentially important role played by early health in intergenerational processes.

Abstract
Accumulating evidence supports the hypothesis of abnormal neurodevelopment in schizophrenia. According to this hypothesis, schizophrenia is the consequence of prenatal abnormalities resulting from the interaction of genetic and environmental factors. In line with this hypothesis, several studies indicate that pregnancy and birth complications are risk factors for developing schizophrenia. At the clinical level, multiple cognitive deficits can be found in schizophrenic patients before illness onset. The neurodevelopmental hypothesis considers these cognitive deficits as the expression of early abnormalities on the central nervous system development. Consistently, brain imaging data show early structural abnormalities and abnormal progressive brain changes in schizophrenia. Finally, genetic and histological data indicate that genes associated with schizophrenia are involved in brain development.

Abstract
Diminished inhibitory gating of cerebral auditory evoked responses is transmitted in families with psychoses as an endophenotype related to the genetic risk for these illnesses. To assess whether the endophenotype is already expressed in infants of parents with psychotic illness and to assess effects of other known risk factors for schizophrenia, ie, maternal cigarette smoking and depression, inhibitory gating of cerebral auditory evoked responses was evaluated by comparing the P1 evoked responses to the first and second of paired auditory stimuli. Cerebral evoked responses were recorded during active sleep from 22 infants with a parent diagnosed with a psychotic illness and 129 infants with parents with no such history. Of these infants, 25 were prenatally exposed to nicotine (16 from the comparison group and 9 from the group with parental psychosis). Mothers of 35 infants had diagnoses of major depressive disorder. Parental psychosis (P = .032) and exposure to maternal smoking (P = .012) both resulted in diminished inhibitory gating in infant offspring. Compared to infants of mothers who did not smoke and who had neither parental psychosis nor maternal depression, diminished inhibitory gating was observed in infants with parental psychosis (P = .027) and in infants with maternal depression (P = .049). Diminished inhibitory gating of auditory evoked response in infants who have risk factors for schizophrenia mirrors reports of its familial transmission in adults. The results further indicate that the phenotypic expression of familial genetic and environmental risks for psychosis is already manifest very early in development.

Abstract
BACKGROUND Many reports from European countries suggest that acute episodes of psychosis are more frequent among immigrants from the Caribbean than among their non-immigrant peers. AIM The aim of this selective review is to examine how the social correlates of migration to Canada interact with biological mechanisms to contribute to psychosis in the Caribbean population. METHOD PubMed and JSTOR social science databases (between 1966 and 2010) were searched using the following search terms: psychiatric genetics; dopamine pathways; Caribbean family structure and child rearing; cannabis and psychosis; obstetric complications and schizophrenia; social defeat; social capital; racial discrimination; urbanicity; immigration; assimilation; and immigration. This was followed by the cross-checking of references pertinent to Canada. RESULTS There was no information about the prevalence of psychosis in Afro-Caribbean immigrant groups to Canada. There was a suggestion that the form the acute episode takes may differ, depending perhaps on the island of origin. CONCLUSION Ethnicity and migration influence susceptibility and response to psychotic illness in a number of distinct and interacting ways depending both on the host country and the country of origin. Understanding the pathways can help to protect the health of immigrants.

Abstract
Phenotype mining is a novel approach for elucidating the genetic basis of complex phenotypic variation. It involves a search of rich phenotype databases for measures correlated with genetic variation, as identified in genome-wide genotyping or sequencing studies. An initial implementation of phenotype mining in a prospective unselected population cohort, the Northern Finland 1966 Birth Cohort (NFBC1966), identifies neurodevelopment-related traits-intellectual deficits, poor school performance and hearing abnormalities-which are more frequent among individuals with large (>500 kb) deletions than among other cohort members. Observation of extensive shared single nucleotide polymorphism haplotypes around deletions suggests an opportunity to expand phenotype mining from cohort samples to the populations from which they derive.

Abstract
Structural brain abnormalities have become an established feature of schizophrenia and increasing evidence points towards the progressive nature of these abnormalities. The brain abnormalities are most profound in early onset cases, which have a severe, treatment refractory phenotype and more salient genetic features. Unique insights could thus be gained in schizophrenia pathology from studying the earliest manifestations of the illness. This paper reviews and updates the findings on anatomic brain development in patients with very early onset schizophrenia while showing preliminary data from ongoing studies. Collectively, our studies demonstrate that childhood-onset schizophrenia (COS) subjects show progressive loss of gray matter, delayed/disrupted white matter (WM) growth, and a progressive decline in cerebellar volume, some of which are shared by their healthy siblings. The developmental patterns or the 'trajectories' of brain development are often more striking than anatomic brain differences at any one point in time; highlighting the importance of longitudinal studies. The sibling findings of partially shared gray matter (GM) deficits which appear to normalize with age, along with other genetic analyses, provide evidence that the brain developmental 'patterns/trajectories' for several regions at particular ages could be useful endophenotypes (trait markers).
