Correlates of deliberate self-harm among youth with bipolar disorder

Childhood Trauma and Self-harm in Youths with Bipolar Disorders

BACKGROUND

Bipolar disorders (BD) in youth are associated with a high risk of self-harm behaviors. Childhood trauma (CT) is a relevant environmental stressor that is related to both BD diagnosis and self-harm in adulthood. It is not yet established whether CT may impact self-harm risk in youth. Therefore, the aim of this study was to investigate the distribution patterns of CT in youth BD with and without self-harm.

METHODS

We assessed 273 participants (aged 13-25 years), 96 youths with BD according to DSM-5 criteria and 177 healthy controls (HC). History of CT was obtained using the Childhood Trauma Questionnaire (CTQ). The association between CT and self-harm was tested using multivariate statistical models.

RESULTS

Over 45% of participants with BD reported lifetime self-harm. The BD Self-harm group reported more emotional abuse, emotional neglect, sexual abuse, and physical abuse than HC. The BD No-Self-harm group reported more emotional abuse than HC. The BD Self-harm group reported more emotional abuse and neglect than the BD No-Self-harm group. The BD Self-harm group also reported separated parents, hospitalizations, smoking, use of antiepileptics, antipsychotics and lithium. Emotional abuse was an independent predictor of self-harm in youths with BD.

CONCLUSION

Findings support the importance of assessing CT, in particular emotional abuse, in youth with BD at risk for self-harm.

Inflammation Markers in Patients with Bipolar Disorder Who Have Committed Offenses and Their Relationship with Criminal Behavior

Background and Objectives: This study aimed to examine the function of various inflammation parameters and their interactions in the pathology of Bipolar disorder (BD) and to assess whether they could be biomarkers in the relationship between criminal behavior and BD. Materials and Methods: Overall, 1029 participants, including 343 patients with BD who have committed offenses, 343 nonoffending patients with BD, and 343 healthy controls, were included in this retrospective study. Neutrophil, lymphocyte, monocyte, and platelet counts; high-density lipoprotein (HDL-c) levels; systemic immune-inflammatory index (SII), systemic inflammatory response index (SIRI), neutrophil to high-density lipoprotein ratio (NHR), lymphocyte to high-density lipoprotein ratio (LHR), monocyte to high-density lipoprotein ratio (MHR), platelet to high-density lipoprotein ratio (PHR) were measured. Results: Significant differences were observed between the groups in terms of SII, SIRI, NHR, LHR, MHR, PHR, neutrophil, and monocyte values (p < 0.001). The lymphocyte counts were significantly higher in the patients with BD who committed offenses (p = 0.04). The platelet counts were significantly lower in the patients with BD who committed offenses compared to nonoffending patients with BD (p = 0.015). The HDL-c levels were significantly lower in the patients with BD who have committed offenses than those of nonoffending patients with BD (p < 0.001). Bipolar disorder, not receiving active psychiatric treatment, having a diagnosis of bipolar manic episodes, and having low platelet and HDL values constitute a risk of involvement in crime. Conclusions: The present study emphasizes the role of systemic inflammation in the pathophysiology of patients with BD with and without criminal offenses and the relationship between inflammation and criminal behavior.

Association Between Social Determinants of Health and Deliberate Self-Harm Among Youths With Psychiatric Diagnoses

OBJECTIVE

The authors sought to examine the association between adverse social determinants of health (SDoHs) and risk for self-harm among youths.

METHODS

The authors performed a retrospective longitudinal analysis of Ohio Medicaid claims data (April 1, 2016-December 31, 2018) of 244,958 youths (ages 10-17 years) with a primary psychiatric diagnosis. SDoHs were identified from ICD-10 codes and classified into 14 categories, encompassing abuse and neglect, child welfare placement, educational problems, financial problems, exposure to violence, housing instability, legal issues, disappearance or death of a family member, family disruption by separation or divorce, family alcohol or drug use, parent-child conflict, other family problems, social and environmental problems, and nonspecific psychosocial needs. Cox proportional hazards analysis was used to examine the association between SDoHs and self-harm (i.e., nonsuicidal self-injury or suicide attempt). Analyses controlled for demographic characteristics and comorbid psychiatric and general medical conditions.

RESULTS

During follow-up after an index claim event, 51,796 youths (21.1%) had at least one adverse SDoH indicator, and 3,262 (1.3%) had at least one self-harm event. Abuse and neglect (hazard ratio [HR]=1.90, 99% CI=1.70-2.12), child welfare placement (HR=1.32, 99% CI=1.04-1.67), parent-child conflict (HR=1.52, 99% CI=1.23-1.87), other family problems (HR=1.25, 99% CI=1.01-1.54), and nonspecific psychosocial needs (HR=1.41, 99% CI=1.06-1.89) were associated with significantly increased hazard of self-harm.

CONCLUSIONS

Adverse SDoHs were significantly associated with self-harm, even after controlling for demographic and clinical characteristics, underscoring the need for capturing SDoH information in medical records to identify youths at elevated suicide risk and to inform targeted interventions.
