Risk of Schizophrenia Increases After All Child and Adolescent Psychiatric Disorders: A Nationwide Study.

ABSTRACT:

Objective

Earlier smaller studies have shown associations between child and adolescent psychiatric disorders and schizophrenia. Particularly, attention-deficit/hyperactivity-disorder and autism have been linked with schizophrenia. However, large-scale prospective studies have been lacking. We, therefore, conducted the first large-scale study on the association between a broad spectrum of child and adolescent psychiatric disorders and the risk of being diagnosed with schizophrenia.

Methods

Danish nationwide registers were linked to establish a cohort consisting of all persons born during 1990-2000 and the cohort was followed until December 31, 2012. Data were analyzed using survival analyses and adjusted for calendar year, age, and sex.

Results

A total of 25138 individuals with child and adolescent psychiatric disorders were identified, out of which 1232 individuals were subsequently diagnosed with schizophrenia spectrum disorders. The risk of schizophrenia spectrum disorders was highly elevated, particularly within the first year after onset of the child and adolescent psychiatric disorder, and remained significantly elevated >5 years with an incidence rate ratio of 4.93 (95% confidence interval: 4.37-5.54).We utilized the cumulated incidences and found that among persons diagnosed with a child and adolescent psychiatric disorder between the ages 0-13 years and 14-17 years, 1.68% and 8.74 %, respectively, will be diagnosed with a schizophrenia spectrum disorder <8 years after onset of the child and adolescent psychiatric disorder.

Conclusions

The risk of being diagnosed with schizophrenia spectrum disorders after a child and adolescent psychiatric disorder was significantly increased particularly in the short term but also in the long-term period.

Project description:Irritable bowel syndrome (IBS) is the most common functional gastrointestinal (GI) disorder observed in patients who visit general practitioners for GI-related complaints. A high prevalence of psychiatric comorbidities, particularly anxiety and depressive disorders, has been reported in patients with IBS. However, a clear temporal relationship between IBS and psychiatric disorders has not been well established.We explored the relationship between IBS and the subsequent development of psychiatric disorders including schizophrenia, bipolar disorder, depressive disorder, anxiety disorder, and sleep disorder.We selected patients who were diagnosed with IBS caused by gastroenteritis, according to the data in the Taiwan National Health Insurance Research Database. A comparison cohort was formed of patients without IBS who were matched according to age and sex. The incidence rate and the hazard ratios (HRs) of subsequent new-onset psychiatric disorders were calculated for both cohorts, based on psychiatrist diagnoses.The IBS cohort consisted of 4689 patients, and the comparison cohort comprised 18756 matched control patients without IBS. The risks of depressive disorder (HR = 2.71, 95% confidence interval [CI] = 2.30-3.19), anxiety disorder (HR = 2.89, 95% CI = 2.42-3.46), sleep disorder (HR = 2.47, 95% CI = 2.02-3.02), and bipolar disorder (HR = 2.44, 95% CI = 1.34-4.46) were higher in the IBS cohort than in the comparison cohort. In addition, the incidence of newly diagnosed depressive disorder, anxiety disorder, and sleep disorder remained significantly increased in all of the stratified follow-up durations (0-1, 1-5, ≥5 y).IBS may increase the risk of subsequent depressive disorder, anxiety disorder, sleep disorder, and bipolar disorder. The risk ratios are highest for these disorders within 1 year of IBS diagnosis, but the risk remains statistically significant for more than 5 years. Clinicians should pay particular attention to psychiatric comorbidities in IBS patients.

Project description:ObjectivesTo the best of our knowledge, no case-control study on child and adolescent psychiatric outpatients has investigated the clinical characteristics of patients with child-to-parent violence (CPV). The current study aimed to evaluate the clinical characteristics of child and adolescent psychiatric patients with CPV.Setting and participantsThis research included child and adolescent psychiatric patients who were aged 10-15 years during their initial consultation. The participants were allocated to one of two groups: children with CPV (CPV group, n=109) and without CPV (non-CPV group, n=713).Outcome measuresThis study analysed data including age, sex, diagnostic classification of the primary diagnosis, antisocial behaviour, suicidal attempt or self-harm and refusal to attend school. Moreover, a history of abuse by parents was investigated. Psychological rating scales such as the Spence Children's Anxiety Scale, Depression Self-Rating Scale for Children, Tokyo Autistic Behavior Scale, Attention-deficit/Hyperactivity Disorder-Rating Scale and Oppositional Defiant Behavior Inventory were used.ResultsOf 822 patients who sought consultation in our department, 109 (13.26%) were included in the CPV group during the first consultation. Compared with the non-CPV group, the CPV group had significantly higher proportions of patients who experienced physical abuse, psychological abuse and who witnessed violence between parents. Meanwhile, the proportion of patients with neurodevelopmental disorders was significantly higher in the CPV group than in the non-CPV group. Regarding developmental characteristics, impulsivity might be correlated with CPV. Moreover, violence and behavioural problems outside of home were associated with CPV.ConclusionsIn patients with CPV who sought consultation, the findings of the current study should be considered to understand invisible side and to facilitate the use of appropriate treatment approaches. However, a prospective study should be performed to investigate the causality between CPV and clinical characteristics.

Project description:ObjectiveTo investigate whether anorexia nervosa (AN), bulimia nervosa (BN), binge eating disorder (BED), and other specified feeding and eating disorders (OSFED), including purging disorder (PD), subthreshold BN, and BED at ages 14 and 16 years, are prospectively associated with later depression, anxiety disorders, alcohol and substance use, and self-harm.MethodEating disorders were ascertained at ages 14 and 16 years in 6,140 youth at age 14 (58% of those eligible) and 5,069 at age 16 (52% of those eligible) as part of the prospective Avon Longitudinal Study of Parents and Children (ALSPAC). Outcomes (depression, anxiety disorders, binge drinking, drug use, deliberate self-harm, weight status) were measured using interviews and questionnaires about 2 years after predictors. Generalized estimating equation models adjusting for gender, socio-demographic variables, and prior outcome were used to examine prospective associations between eating disorders and each outcome.ResultsAll eating disorders were predictive of later anxiety disorders. AN, BN, BED, PD, and OSFED were prospectively associated with depression (respectively AN: odds ratio [OR] = 1.39, 95% CI = 1.00-1.94; BN: OR = 3.39, 95% CI = 1.25-9.20; BED: OR = 2.00, 95% CI = 1.06-3.75; and PD: OR = 2.56, 95% CI = 1.38-4.74). All eating disorders but AN predicted drug use and deliberate self-harm (BN: OR = 5.72, 95% CI = 2.22-14.72; PD: OR = 4.88, 95% CI = 2.78-8.57; subthreshold BN: OR = 3.97, 95% CI = 1.44-10.98; and subthreshold BED: OR = 2.32, 95% CI = 1.43-3.75). Although BED and BN predicted obesity (respectively OR = 3.58, 95% CI = 1.06-12.14 and OR = 6.42, 95% CI = 1.69-24.30), AN was prospectively associated with underweight.ConclusionsAdolescent eating disorders, including subthreshold presentations, predict negative outcomes, including mental health disorders, substance use, deliberate self-harm, and weight outcomes. This study highlights the high public health and clinical burden of eating disorders among adolescents.
