A nationwide study on time spent on social media and self-harm among adolescents.

Self-harm among adolescents has increased in many countries, but few studies have examined possible explanations. One explanation could be the changes in the way adolescents socialize and use of social media. We explored the relationship between past year self-harm and time spent on social media, employing data from a nationwide cross-sectional survey among students in grades 8 through 11 in Norway (N = 37,268). The association was estimated in logistic regression models and we adjusted for identified confounders and stratified on gender, age group and depressive symptoms. A total of 16.1% of the study population reported to have self-harmed in the past year. This proportion was elevated among those spending more than 3 h daily on social media (unadjusted OR = 2.74 (CI 2.58.-2.90)). Adjustment for confounders modified the association (OR = 1.49 (CI 1.39-1.60)). In stratified analyses, adjusted OR did not differ significantly by gender or age The association between time spent on social media and self-harm was weaker among adolescents with severe depressive symptoms (adjusted OR = 1.38 (CI 1.22-1.55)), than among those with mild or no symptoms (adjusted OR = 1.70 (CI 1.56-1.86)). Risk of self-harm was elevated among those who spent 3 or more hours daily on social media, also after controlling for other factors. Further studies are needed to explore the nature and underlying mechanisms of this association. Strengthening the evidence will help informing the development of adequate measures to prevent self-harm.

The temporal association between suicide and comorbid mental disorders in people treated for substance use disorders: a National registry study.

BACKGROUND: The time after contact with specialized health services for mental health and substance use is associated with an increased risk of suicide, where temporal aspects of suicide and comorbid mental disorders in patients with substance use disorders could be associated. This study aimed to examine the temporal association between time from last treatment contact to suicide and comorbid mental disorders in patients with substance use disorders. METHODS: This study is a historical prospective case series using nationwide registry data. It included 946 individuals registered the year before suicide with a substance use disorder (F10-F19) in Norway's specialized health services for treating substance use and mental health disorders between 2010 and 2020. The outcome was the number of weeks from the last contact with services to suicide. The exposure was comorbid mental disorders divided into 'no comorbid mental disorder'; 'psychosis or bipolar disorders' (F20-F31), 'depressive or anxiety disorders' (F32-F49); and 'personality disorders' (F60-F69). Covariates included gender, age, last diagnosed substance use disorder, registered deliberate self-harm last year, and the number of in- and outpatient contacts the previous year. RESULTS: The number of weeks from last service contact to suicide differed (p = < 0.001) between patients with no comorbid mental disorders (Median = 7; IQR 2-23), psychosis or bipolar disorders (Median = 2; IQR = 1-7), depressive or anxiety disorders (Median = 3; IQR = 1-11) and personality disorders (Median = 1; IQR = 1-5.5). Significantly decreased adjusted incidence rate ratios (aIRR) were found for psychosis or bipolar disorders [aIRR = 0.67 (95% CI 0.53-0.85)] and personality disorders [aIRR = 0.56 (0.42-0.77)] compared to no comorbid mental disorder when adjusted for individual characteristics and service contact. For depressive and anxiety disorders compared to no comorbid mental disorder, the association was significant when adjusted for individual characteristics [aIRR = 0.55 (0.46-0.66)]. CONCLUSIONS: While patients with substance use disorders generally died by suicide a short time after contact with services, patients with comorbid mental disorders died an even shorter time after such contact and significantly shorter than patients without such comorbidities.

Levels of IL-6 are Associated with Lifetime Attempted Suicide in Alcohol Use Disorder Patients.

Background: Patients with alcohol use disorder (AUD) have an increased risk of suicide. Neuroimmunological measures, such as cytokines, are shown to deviate in people with attempted suicide. Few studies have investigated this among AUD patients. Patients and Methods: One-hundred and fourteen patients undergoing residential treatment for AUD were interviewed on lifetime suicide attempts (SA) along with several other background variables and clinical characteristics. Serum blood samples were drawn for analysis of cytokines. Results: Thirty-one patients (27%) reported at least one SA. These patients had more symptoms of current affective disorders and more severe dependence. In bivariate analysis only IL-6 and IL-10 appeared to be associated with lifetime SA but without reaching statistical significance. In multivariate linear regression, adjusting for sex, nicotine use, somatic illness, and the use of anti-inflammatory drugs, IL-6 was associated to SA (p = 0.033). Conclusion: The cytokine IL-6 has repeatedly been found to be associated with suicidality. The present study concurs with this role of IL-6 in a naturalistic observational study of AUD patients.

Suicide in services for mental health and substance use: A national hybrid registry surveillance system.

Suicide is strongly associated with mental health and substance use disorders, which makes mental health- and substance misuse services important areas for suicide prevention. The aim of The Norwegian Surveillance System for Suicide in Mental Health and Substance Use Services is to describe all suicide deaths in Norway that occur within one year after contact with mental health and substance misuse services. The study uses a hybrid registry case series design. It consists of a yearly linkage between the Norwegian Cause of Death Registry and the Norwegian Patient Registry, which is linked with a questionnaire. The linkage is conducted by using a cryptographic hash function of the deceased's personal id, thus ensuring that the project can link data across sources without the use of directly identifiable information. This indirect linkage ensures the deceased's confidentiality. Moreover, the The Norwegian Surveillance System for Suicide shows how administratively collected data can be harnessed and used for surveillance. Both use of hybrid registry designs and linkage through cryptographic hash functions might contribute to the development of health informatics as well as quality improvement in health care.

Trajectories of Service Contact before Suicide in People with Substance Use Disorders-A National Register Study.

OBJECTIVE: This study aimed to identify trajectories of service use during the last year before suicide death and the characteristics associated with the trajectories in patients with substance use disorders. METHODS: This study used a national registry data linkage, which included all patients with substance use disorders who died by suicide in Norway between 2010 and 2018. In- and outpatient contacts with mental health or substance use services during the last year before suicide death was analyzed by week using Sequence State Analysis and cluster analysis to identify trajectories. Logistic regression was used to measure the association between the characteristics and the trajectories. RESULTS: We identified four trajectories of service contact. A brief contact trajectory (n = 366) with a low proportion of weeks in contact (M weeks = 8.3), associated with less psychosis or bipolar disorder (aOR = 0.13 (0.08-0.22)) and higher age. A regular contact trajectory (n = 160), with a higher proportion of contact (M weeks = 47.9), associated with psychosis or bipolar disorder (aOR = 3.66 (2.10-6.47)) and depressive or anxiety disorder (aOR = 3.11 (1.93-5.13)). An intermittent contact trajectory (n = 195) with most contacts with outpatient substance use disorder services (M weeks = 9.7). A continuous contact trajectory (n = 109) with a high proportion of inpatient contact (M weeks = 44.5), strongly associated with psychosis or bipolar disorder (aOR = 6.08 (3.26-11.80)). CONCLUSION: Longitudinal descriptions of service use reveal different trajectories that are important to consider when developing policies or interventions to reduce the risk of suicide death in patients with substance use disorders.

Sex-specific factors associated with lifetime suicide attempt among patients with alcohol use disorders.

BACKGROUND: Patients with alcohol use disorder (AUD) are at high risk for suicide attempts. Mental health problems along with AUD-related factors may contribute to this increased risk. Studies have shown sex differences in rates and correlates of suicide attempts. AIMS: The purpose of the study was to examine mental-health-related and AUD-related factors associated with suicide attempt separately in female and male AUD patients. METHOD: We collected information about lifetime suicide attempt and mental-health- and AUD-related factors for AUD in-patients (n = 114; 32 females) receiving rehabilitative treatment. RESULTS: The prevalence of lifetime suicide attempt was 27%, and the rate was similar in both sexes. Among females, current depressive symptoms and current post-traumatic stress disorder diagnosis were associated with suicide attempt. In male AUD patients, among the mental-health-related factors, lifetime major depression, panic disorder, social phobia, childhood sexual abuse and antisocial personality disorder were associated with suicide attempt. In addition, AUD-related factors including longer duration of drinking, history of delirium tremens, greater severity of AUD and lower levels of prolactin were associated with suicide attempt in males. CONCLUSIONS: Our results indicate that suicide attempts in female AUD patients were more mental-health-related, whereas those in males were also related to the severity of AUD. This suggests that a suicide prevention programme for AUD patients would benefit from a sex-based understanding of the risk factors.

Suicide among users of mental health and addiction services in the first 10 months of the COVID-19 pandemic: observational study using national registry data.

Although many studies have reported no rise in suicides in the general population following the COVID-19 pandemic, little is known regarding mental health and substance misuse service patients, groups who have reportedly faced substantial reductions in their access to care during phases of lockdown. However, in this observational study using national registry data, during the first 10 months of the pandemic we found no evidence of an increased risk among people in recent (within 12 months) contact with secondary care. Both long-term and differential effects on subgroups remain to be studied.

Suicide After Contact With Child and Adolescent Mental Health Services-A National Registry Study.

Background: Research has shown a strong association between suicide and mental disorders, and people in contact with services for mental health and substance use are known to be at high risk of suicide. Still, few studies have previously described suicide among young people in contact with Child and Adolescent Mental Health Services. Aim: The aim of this study is to examine the prevalence of contact and suicide rates by gender and age groups, and to describe patient demographics and service utilization in secondary mental health services. Methods: All young people in contact with Child and Adolescent Mental Health Services in the year prior to death in the period 2008-2018 were identified by linking the Norwegian Cause of Death Registry and the Norwegian Patient Registry. We estimated the prevalence of contact and suicide rates among those with and without contact, by gender and age groups. Characteristics of treatment contact were compared between boys and girls. Variables with significant differences were entered into a multivariate logistic regression model using gender as an outcome. Results: More girls (39.7%) than boys (11.8%) had contact with Child and Adolescent Mental Health Services in the year prior to death. Among girls, suicide rates per 100,000 patients increased linearly in the age groups 10-13, 14-16, and 17-19 years: 5, 22, and 38 per 100,000 patients, respectively. Among boys, the suicide rate increased sharply from 7 per 100,000 patients in the age group 14-16 years to 40 per 100,000 patients in the 17-19-year-old group. In the age-adjusted multivariate model, boys were 4.07 (1.22-14.44, p = 0.024) times more likely to have terminated contact at the time of death. Conclusion: This study shows gender differences in both suicide rates and service utilization among young people in contact with Child and Adolescent Mental Health Services before suicide, and future studies should focus on identifying the causes of these gender differences in service contact.

The Impact of a Widely Publicized Celebrity Suicide on Suicide-Related Internet Search Activity.

OBJECTIVE: Media reporting of celebrities' deaths by suicide are prone to suicide contagion effects. The aim of the current study is to examine whether the widely publicized celebrity suicide of Ari Behn in Norway was associated with changes in search activity of suicide-related terms. METHOD: Search activity data for the terms "suicide," "Ari Behn suicide," "how to suicide," and "suicide prevention" were retrieved from Google Trends. We analyzed data as an interrupted time series and used T-tests to compare means before and after the suicide. Crude linear models examining the association between searches for "suicide" over time and an adjusted model controlling for searches after "Ari Behn suicide" were built. The models were tested with structural change tests. RESULTS: A significant increase in search activity for "suicide" (p = < .001), "Ari Behn suicide" (p = .002), and "how to suicide" (p = .006) was found after the suicide. Searches for "suicide prevention" were not significant (p = .11). The structural change test was significant both for the model that did not control for explicit searches (p = <.001) and for the model controlled for explicit searches (p = <.001). CONCLUSIONS: A recent widely publicized suicide in Norway was associated with increases in Google searches for suicide. No indications of the Papageno effect were found. The media should be cautious when reporting about the suicides of prominent public persons. Compliance with generally accepted media reporting guidelines may need more attention.HIGHLIGHTSWe found a significant increase in search activity for suicide related terms.More attention should be devoted to careful media reporting on celebrity suicides.Media should consider the volume of publicity carefully.

Suicide after contact with substance misuse services: a national registry study.

BACKGROUND: People with substance use disorders have a well-known increased risk for taking their own life. Previous research has mainly focused on suicide in mental health services, whereas there is limited knowledge regarding suicide after contact with substance misuse services. AIMS: The aim of the current study was to describe the utilisation of both mental health services and substance misuse services among people who have died by suicide within a year of contact with substance misuse services. METHOD: We used an explanatory observational design, where all suicide deaths in the period from 2009 to 2016 were retrieved from the Norwegian Cause of Death Registry and linked with the Norwegian Patient Registry. The people who had been in contact with substance misuse services within a year before their death were included in the sample (n = 419). The analysis was stratified by gender, and variables with significant differences between men and women were entered into a multivariate logistic regression model. RESULTS: More women (73.5%) than men (60.6%) had contact with mental health services in their last year (P = 0.01). In the adjusted logistic regression model, poisoning was more common among women (adjusted odds ratio (AOR) = 1.81, 95% CI 1.09-3.02) and women were more likely to be diagnosed with a sedative, hypnotic or anxiolytic use disorder (F14) in their last year (AOR = 2.77, 95% CI 1.37-5.68). CONCLUSIONS: This study highlights gender differences for suicide in substance misuse services, and the importance of collaboration and cooperation between substance misuse services and mental health services.

Change in prevalence of self-harm from 2002 to 2018 among Norwegian adolescents.

BACKGROUND: Self-harm is prevalent among adolescents and associated with mental health problems and negative life-events. Few studies have examined changes in its prevalence related to these factors. This study explored whether changes in prevalence of self-harm among adolescents had occurred, and to what extent changes in associated factors may have contributed. METHODS: Two cross-sectional school-based surveys among adolescents (grades 8-10) in Norway were conducted in 2002 (N = 5842) and in 2017/18 (N = 29 063). Past year prevalence of self-harm and identical variables on risk factors was analyzed in hierarchical logistic regression to examine whether and to what extent changes in self-harm correlates could explain periodical change in prevalence of self-harm. RESULTS: An increase from 4.1% to 16.2% in self-harm prevalence was observed from 2002 to 2017/18. The increase was relatively larger among girls compared to boys and among 8th graders compared to 10th graders. Among the assessed risk factors for self-harm, depressive symptoms increased, while anti-social behavior, exposure to violent acts and drinking to intoxication decreased. The increase in depressive symptoms contributed to explain increase in self-harm. This contribution was outweighed by the decrease in other risk factors. CONCLUSIONS: Self-harm prevalence increased 4-fold among Norwegian adolescents over a 15-year period. While exposure to several risk factors for self-harm changed substantially in this period, these risk factors could in sum not explain any of the increase in self-harm.

Contact With Mental Health Services Prior to Suicide: A Systematic Review and Meta-Analysis.

OBJECTIVE: Access to mental health care is regarded as a central suicide prevention strategy. This is the first systematic review and meta-analysis of the prevalence of contact with mental health services preceding suicide. METHODS: A systematic search for articles reporting prevalence of contact with mental health services before suicide was conducted in MEDLINE and PsycINFO, restricted to studies published from January 1, 2000, to January 12, 2017. A random-effects meta-analysis with double arcsine transformations was conducted, with meta-regression used to explore heterogeneity. RESULTS: Thirty-five studies were included in the systematic review, and 20 were included in the meta-analysis. Among suicide decedents in the population, 3.7% (95% confidence interval [CI]=2.6%-4.8%) were inpatients at the time of death. In the year before death, 18.3% (CI=14.6%-22.4%) of suicide decedents had contact with inpatient mental health services, 26.1% (CI=16.5%-37.0%) had contact with outpatient mental health services, and 25.7% (CI=22.7%-28.9%) had contact with inpatient or outpatient mental health services. Meta-regression showed that women had significantly higher levels of contact compared with men and that the prevalence of contact with inpatient or outpatient services increased according to the sample year. CONCLUSIONS: Contact with services prior to suicide was found to be common and contact with inpatient or outpatient mental health services before suicide seems to be increasing. However, the reviewed studies were mainly conducted in Western European and North American countries, and most studies focused on psychiatric hospitalization, which resulted in limited data on contact with outpatient services. Better monitoring and data on suicides that occur during and after treatment seem warranted.
