Insomnia symptoms and suicidality in the National Comorbidity Survey - Adolescent Supplement.

ABSTRACT: In this paper, we examined the relationship between insomnia symptoms and suicidality in a national sample of US adolescents, while controlling for several psychiatric disorders that are known to be associated with suicidality. Additionally, we examined whether insomnia symptoms interact to affect any suicidality variables.Study participants were 10,123 adolescents between the ages of 13-18 from the National Comorbidity Survey - Adolescent Supplement (NCS-A).In bivariate analyses, all insomnia symptoms (i.e., difficulty falling asleep, difficulty staying asleep, and early morning awakening) were associated with suicide ideation, plan and attempts. In multivariate analyses, controlling for substance use, mood and anxiety disorders, as well as important covariates, difficulties falling and staying asleep had a significant relationship with 12-month and lifetime suicide variables while early morning awakening did not.Two of the three insomnia symptoms had a significant association with suicide thoughts and plan even after controlling for psychiatric disorders that were known to affect suicidality. Having trouble falling sleeping or staying asleep had both direct and indirect relationships (via substance use, mood and anxiety disorders) on suicidal behavior. Assessment and treatment of sleep disturbances may reduce the risk for suicidality in adolescents.

Project description:BackgroundAlthough DSM-IV attention deficit hyperactivity disorder (ADHD) is known to be associated with numerous adverse outcomes, uncertainties exist about how much these associations are mediated temporally by secondary co-morbid disorders.MethodThe US National Comorbidity Survey Replication Adolescent Supplement (NCS-A), a national survey of adolescents aged 13-17 years (n = 6483 adolescent-parent pairs), assessed DSM-IV disorders with the World Health Organization (WHO) Composite International Diagnostic Interview (CIDI). Statistical decomposition was used to compare direct effects of ADHD with indirect effects of ADHD through temporally secondary mental disorders (anxiety, mood, disruptive behavior, substance disorders) in predicting poor educational performance (suspension, repeating a grade, below-average grades), suicidality (ideation, plans, attempts) and parent perceptions of adolescent functioning (physical and mental health, interference with role functioning and distress due to emotional problems).ResultsADHD had significant gross associations with all outcomes. Direct effects of ADHD explained most (51.9-67.6%) of these associations with repeating a grade in school, perceived physical and mental health (only girls), interference with role functioning and distress, and significant components (34.5-44.6%) of the associations with school suspension and perceived mental health (only boys). Indirect effects of ADHD on educational outcomes were predominantly through disruptive behavior disorders (26.9-52.5%) whereas indirect effects on suicidality were predominantly through mood disorders (42.8-59.1%). Indirect effects on most other outcomes were through both mood (19.8-31.2%) and disruptive behavior (20.1-24.5%) disorders, with anxiety and substance disorders less consistently important. Most associations were comparable for girls and boys.ConclusionsInterventions aimed at reducing the adverse effects of ADHD might profitably target prevention or treatment of temporally secondary co-morbid disorders.

Project description:To examine whether a first abortion increases risk of mental health disorders compared with a first childbirth with and without considering prepregnancy mental health and adverse exposures, childhood economic status, miscarriage history, age at first abortion or childbirth, and race or ethnicity.A cohort study compared rates of mental disorders (anxiety, mood, impulse-control, substance use, eating disorders, and suicidal ideation) among 259 women postabortion and 677 women postchildbirth aged 18-42 years at the time of interview from The National Comorbidity Survey-Replication.The percentage of women with no, one, two, and three or more mental health disorders before their first abortion was 37.8%, 19.7%, 15.2%, and 27.3% and before their first childbirth was 57.9%, 19.6%, 9.2%, and 13.3%, respectively, indicating that women in the abortion group had more prior mental health disorders than women in the childbirth group (P<.001). Although in unadjusted Cox proportional hazard models, abortion compared with childbirth was associated with statistically significant higher hazards of postpregnancy mental health disorders, associations were reduced and became nonstatistically significant for five disorders after adjusting for the aforementioned factors. Hazard ratios and associated 95% confidence intervals dropped from 1.52 (1.08-2.15) to 1.12 (0.87-1.46) for anxiety disorders; from 1.56 (1.23-1.98) to 1.18 (0.88-1.56) for mood disorders; from 1.62 (1.02-2.57) to 1.10 (0.75-1.62) for impulse-control disorders; from 2.53 (1.09-5.86) to 1.82 (0.63-5.25) for eating disorders; and from 1.62 (1.09-2.40) to 1.25 (0.88-1.78) for suicidal ideation. Only the relationship between abortion and substance use disorders remained statistically significant, although the hazard ratio dropped from 3.05 (1.94-4.79) to 2.30 (1.35-3.92).After accounting for confounding factors, abortion was not a statistically significant predictor of subsequent anxiety, mood, impulse-control, and eating disorders or suicidal ideation. LEVEL OF EVEDIENCE: II.
