Developmental timing of suicide attempts and cardiovascular risk during young adulthood

Twenty-Five Years of National-Level Research on Adolescent and Young Adult Mental Health in the United States

The longitudinal, population-level, biosocial data in the National Longitudinal Study of Adolescent to Adult Health (Add Health) have elucidated the developmental course of mental health across early stages of the life course. This data set also has been invaluable for documenting and unpacking disparities in these developmental patterns by race, ethnicity, socioeconomic status, gender, immigration, and sexuality. Reflecting the larger focus of this special supplement on Add Health as a tool for connecting adolescence to adulthood, this article reviews Add Health research since 2000 based on a search of key mental health terms, primarily describing patterns of two key markers of psychopathology (depressive symptoms, suicidal ideation) that were consistently measured across waves. It situates these patterns from adolescence into adulthood within the developmental ecology organized by the proximate settings of everyday life, the larger social structures organized by a highly stratified society, and the relations of these ecological and structural forces to biological processes. Major foci are the dynamic nature of mental health across the life course and the ways that ecological and physiological influences on mental health differ by group identity and social position.

Relationship between suicide attempt and medical morbidity in adolescent girls

This study assessed whether suicide attempts before 20 years of age were associated with medical morbidity later in life. We carried out a cohort study of 169,806 girls under age 20 years between 1989 and 2019 in Quebec, Canada. The cohort included 8086 girls admitted for suicide attempts, matched on age and year with 161,720 girls with no attempt. Outcomes included hospitalization for medical conditions, such as infection, allergic disorders, autoimmune disease, cardiovascular disease, cancer, and death from nonpsychiatric causes during 31 years of follow-up. We computed hazard ratios (HR) and 95% confidence intervals (CI) for the association of adolescent suicide attempt with these health outcomes using Cox regression models adjusted for preexisting mental illness, substance use disorders, and socioeconomic deprivation. Compared with matched controls, adolescent girls with suicide attempts had a greater risk of hospitalization for infection (HR 1.55, 95% CI 1.44-1.68), allergic disorders (HR 1.72, 95% CI 1.45-2.05), cardiovascular disease (HR 1.31, 95% CI 1.12-1.52), and mortality (HR 3.11, 95% CI 1.69-5.70). Associations were present regardless of the age at the time of the suicide attempt, but were stronger for girls with repeated attempts. Associations were also more pronounced within the first 5 years of the attempt, although suicide attempts remained strongly associated with mortality throughout the 31-year follow-up period. The findings suggest that adolescent girls with suicide attempts have an elevated risk of medical morbidity and mortality and may benefit from closer clinical management to prevent adverse health outcomes.

Emergency Department Use and Inpatient Admissions and Costs Among Adolescents With Deliberate Self-Harm: A Five-Year Follow-Up Study

OBJECTIVE

Self-harm rates among U.S. adolescents have risen substantially. Health and social outcomes among contemporary self-harming youths are infrequently tracked and poorly understood. This study investigated long-term health service utilization (emergency department [ED] visits and inpatient admissions) and inpatient costs among a recent cohort of adolescents with deliberate self-harm.

METHODS

This retrospective cohort study used statewide, all-payer, longitudinally linked discharge data from California. All residents ages 10-19 presenting to EDs in 2010 with deliberate self-harm (N=5,396) were compared with two control groups: a random sample of adolescent ED patients with other complaints, matched on sex, age, residential zip code, and month of index visit (general control patients, N=14,921), and matched ED patients with psychiatric complaints but no self-harm (psychiatric control patients, N=15,835). Outcomes included 5-year rates of ED visits, inpatient admissions, and inpatient costs, overall and for psychiatric and nonpsychiatric complaints separately.

RESULTS

Self-harm patients' ED use, inpatient admissions, and inpatient costs were significantly higher than those of general control patients (by 39%, 81%, and 21%, respectively), when the analysis controlled for confounding demographic and utilization characteristics. Associations mostly persisted, although smaller in magnitude, in comparisons between self-harm and psychiatric control patients. Psychiatric and nonpsychiatric complaints contributed to self-harming adolescents' excess health service utilization and costs.

CONCLUSIONS

Deliberate self-harm among adolescents was found to be associated with long-lasting and costly patterns of health service utilization, often but not exclusively for psychiatric complaints. Future research should investigate the pathways underlying these associations and incorporate service utilization as a key patient outcome.

Examining the Association between Weapon Carrying on School Property and Suicide Attempt among Adolescents in the United States

Suicidal behaviors among adolescents in the United States are the second leading cause of death and has been steadily increasing over the years. Although access to and possession of a weapon may facilitate the transition from suicidal ideation to a suicide attempt, few studies have examined the association between weapon carrying and suicide attempts among adolescents. The objective of this study was to examine the association between weapon carrying on school property and suicide attempt among adolescents. Data for this study came from the 2017 Youth Risk Behavior Surveillance System. A sample of 14,547 adolescents aged 14-18 years old (50.5% female) was analyzed using logistic regression. Of the 14,547 adolescents, 4% carried a weapon on school property, and 7.7% attempted suicide during the past 12 months. In the multivariate logistic regression, adolescents who reported carrying a weapon on school property had more than double the odds of attempting suicide when compared to their counterparts who did not carry a weapon on school property. Other significant predictors of suicide attempt include sexual minority, history of forced sexual intercourse, school bullying and cyberbullying victimization, feeling sad or hopeless, and substance use. Examining the association between weapon carrying and suicide attempt among adolescents would contribute to early identification of adolescents who are likely to engage in suicidal behaviors.

Associations between self-harm and chronic disease among adolescents: Cohort study using statewide emergency department data

INTRODUCTION

We sought to understand the association between youthful self-harm and subsequent chronic disease-related healthcare utilization and whether self-harm reflects unique vulnerability in comparison with severe psychiatric disorders.

METHODS

We used a retrospective matched cohort design with statewide, all-payer, individually linked emergency department (ED) data from California, USA. Risk of future ED visits for common chronic conditions in adolescence (headaches, asthma, epilepsy, diabetes, and gastrointestinal disorders, assessed using ICD-9 diagnoses) were compared between three adolescent study groups presenting to an ED in 2010: self-harm patients (n = 5,484), patients with psychiatric complaints but no self-harm (n = 14,235), and patients with other complaints (n = 16,452). Cohort follow-up ended on Sept. 30, 2015. Analyses were adjusted for patients' prior histories of ED utilization for chronic conditions as well as patient- and area-level sociodemographic characteristics.

RESULTS

Risk of subsequent ED visits was higher among self-harm patients compared to non-psychiatric control patients for subsequent epilepsy- (aRR = 1.77, 95% CI [1.42, 2.21]). Risk of subsequent ED visits was higher among psychiatric patients compared to non-psychiatric control patients for subsequent headache- (aRR = 1.31, 95% CI [1.21, 1.42]), and epilepsy-related problems (aRR = 1.85, 95% CI [1.55, 2.21]). Self-harm patients were at higher risk than psychiatric patients for subsequent gastrointestinal disorder (aRR = 1.76, 95% CI [1.03, 3.01]).

CONCLUSIONS

Findings suggest that self-harm behavior and psychiatric disorders are associated with increased ED utilization for subsequent chronic disease-related ED utilization. Chronic disease among adolescent psychiatric patients should be attended to, potentially involving new models of clinical follow-up care.
