The abnormalities of lipid metabolism in children and adolescents with major depressive disorder and relationship with suicidal ideation and attempted suicide.

Background: Major depressive disorder (MDD) is a widespread health issue in many countries, which has an extremely negative impact on the health of children and adolescents in particular. In the context of depression and metabolic disorders, dyslipidemia and metabolism-related problems become more prominent comorbidities. However, they continue to be the main barrier to the successful recovery of the clinical progress. In this study we investigated the rate of dyslipidemia, additional risk factors among Chinese children and adolescents with MDD, and association of the suicidal behavior with lipid levels. Methods: The study took 756 people from the Third People's Hospital of Fuyang between January 2020 and December 2021, aged between 8 and 18, with major depressive disorders diagnosed according to the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5). We determined the FBG (fasting blood glucose) and lipid parameters in all subjects and also investigated the history of suicidal ideation, the cases of attempted suicide, and the scores of depressive symptoms. Sociodemographic and clinical data were gathered and analyzed using the SPSS-23.0 version. Results: The prevalence of hypercholesterolemia, hypertriglyceridemia, high LDL-C, and low HDL-C were 5.42 % (41/756), 10.58 % (80/756), 3.84 % (29/756) and 5.42 % (41/756) respectively. For hypercholesterolemia and hypertriglyceridemia, they were positive associated with suicidal ideation and suicide attempts, and the positive correlation is shown between low HDL-C levels and suicide attempts. Nevertheless, non-ideation and inversely suicidal attempts were not discovered among high-LDL-C subjects. Logistic analysis showed that high levels of FBG (OR = 2.86, 95 % CI: 1.31-6.25, P = 0.008) and worse LDL-C (OR = 357.82, 95 % CI: 66.16-1935.10, P < 0.001) are the independent associated factors for hypercholesterolemia. More hospitalizations (OR = 1.89, 95 % CI: 1.07-3.35, P = 0.028), obesity (OR = 2.55, 95 % CI: 1.25-5.18, P = 0.010), high levels of TC (OR = 2.15, 95 % CI: 1.03-4.48, P = 0.042), and higher doses of antidepressants (OR = 1.02, 95 % CI: 1.00-1.04, P = 0.029) were independently associated factors for hypertriglyceridemia, while high levels of HDL-C (OR = 0.11, 95 % CI: 0.04-0.31, P < 0.001) were protective factors. In addition, high levels of TC (OR = 113.94, 95 % CI: 20.01-648.85) were statistically different (P < 0.001) and suggested that the factor was significantly related to high LDL-C. Meanwhile, older age (OR = 1.25, 95 % CI: 1.02-1.52, P = 0.030) and high levels of TG (OR = 3.00, 95 % CI: 1.98-4.55, P < 0.001) were independent factors contributing to low HDL-C. Conclusion: The high prevalence of dyslipidemia in childhood and adolescence among children and adolescents with depressive disorder has become a public health issue. Hypercholesterolemia and hypertriglyceridemia showed a positive correlation with suicidal thoughts and suicidal attempts. Monitoring the incidence of suicidal thoughts and attempts among them would carry some predictor meaning in therapy and for jumping back to health.

Body Awareness as a Protective Factor against Suicidal Orientations in College Students.

In this study, binary logistic regression and linear regression analyses were used to examine the relationship between interoceptive body awareness and suicidal orientation among Colombian university students. Additionally, the bootstrap technique was employed to resample and estimate the distribution of the data. The results support the idea that greater interoceptive awareness may protect against suicidal orientation by improving emotional regulation. An inverse relationship was found between interoceptive awareness and suicidal ideation. These findings align with previous literature emphasizing the importance of body awareness for emotional well-being. Further longitudinal research is needed to explore this relationship more deeply.

Suicidal thoughts and behaviors among untreated illicit substance users: a population-based study.

OBJECTIVES: Research regarding the contribution of specific psychoactive substances to suicidality has yielded equivocal results. The present study examined the prevalence and factors associated with suicidal thoughts and behaviors among a population-based sample of untreated illicit substance users. METHODS: A total of 616 illicit substance users who were recruited from high-risk areas of Shiraz using snowball sampling participated in the study. Eligible participants were individuals aged 18 years and older who regularly used one illicit psychoactive substance (e.g., opioids, heroin, cannabinoids, stimulants, hallucinogens) for at least one year and who had received no treatment for their drug use during the past year. Data were collected regarding socio-demographic characteristics, mental history, and substance use habits. Data regarding suicidal thoughts and behaviors were assessed using the Beck Suicidal Ideation Scale (BSIS) and self-reports of previous suicide attempts. Multiple logistic regression analysis was used to identify independent variables associated with suicidality. RESULTS: Among the participants, 23.6% reported having had suicidal thoughts during the past week and 6.7% reported having attempted suicide during the past year. Methamphetamine was reported as the primary substance of use among approximately half of the participants who attempted suicide during past year (49.2%). Multiple logistic regression analysis showed that current suicidal thoughts were independently associated with having no job, a history of mental health condition, previous suicidal attempts, concurrent use of more than one substance, and using methamphetamine and heroin as the primary substances. Suicidal thoughts were not associated with increased odds of regular opium and cannabis use. CONCLUSION: Both methamphetamine and heroin use are significantly associated with current suicidal thoughts. Evaluation of the risk of suicidality by physicians and mental health care professionals in both community and outpatient settings would be especially appropriate among those individuals using these psychoactive substances.

Risk and protective factors for suicidal thoughts and behaviors among Black female and male youth with depression symptoms - United States, 2004-2019.

BACKGROUND: From 2004 to 2019, suicide rates among Black youth increased by 122 % for females and 65 % for males. Guided by the interpersonal theory of suicide, this study explored how perceptions of social support and parental involvement may contribute to suicidal behavior among Black youth aged 12-17 years. METHODS: Data are from the 2004-2019 National Survey on Drug Use and Health (NSDUH). Multivariable logistic regression with backwards elimination was conducted to determine if characteristics associated with outcomes of interest (i.e., suicidal ideation, made a suicide plan, and made a suicide attempt) differed by sex. The characteristics examined included: age, poverty level, health insurance coverage, currently receiving mental health treatment, grades for last completed semester, parental involvement, frequency of arguments or fights with parents, frequency of fights at school or work, parental attitudes, and availability of emotional support. RESULTS: Over 400,000 Black youth with depression symptoms reported suicidal thoughts and behaviors (80 % female). Females had increased odds of suicidal ideation and making a plan if they had no one to talk to about serious problems. Males had increased odds of attempting suicide if they reported academic struggles. LIMITATIONS: This is a cross-sectional study and potential biases may affect generalizability of results. CONCLUSIONS: Risk and protective factors identified in this study aligned with the interpersonal theory of suicide. Evidence-based interventions that focus on increasing connectedness and self-esteem may be effective for Black youth struggling with suicidal ideation. Preventing suicide requires a comprehensive approach including prevention strategies for individuals, families, and communities.

The influence of psychotherapy on individuals who have attempted suicide: A systematic review and meta-analysis.

INTRODUCTION: Suicide is a serious global public health issue, and a history of attempted suicide is the most critical indicator of suicide risk. There are limited studies on the effectiveness of psychotherapy in individuals who have attempted suicide, and other outcome measures related to suicide risk in suicide attempts have not been explored. AIM/QUESTION: This study aimed to systematically review and perform a meta-analysis of the effectiveness of psychotherapy on individuals who have attempted suicide. METHODS: This study conducted a comprehensive literature search of five major databases (PubMed, EMBASE, Cochrane, Web of Science, and Ovid). The protocol for this study is registered with PROSPERO (CRD42023464401) and follows the PRISMA guidelines. RESULTS: This meta-analysis included a total of 34 trials from 32 literature sources. The study involved a total of 6600 participants. The results showed that psychotherapy had a positive effect on reducing the suicidal tendencies of individuals who have attempted suicide and effectively reduced the number of repeated suicide attempts as well as the levels of suicidal ideation, depression, anxiety and hopelessness. IMPLICATIONS FOR PRACTICE: This study concludes that psychotherapy is effective in reducing the suicidal tendencies of individuals who have attempted suicide. Psychological therapy for individuals who have attempted suicide are crucial in preventing future suicidal behaviours.

Opening the black box of registration practice for self-harm and suicide attempts in emergency departments: a qualitative study.

BACKGROUND: The World Health Organization has called for improved surveillance of self-harm and suicide attempts worldwide to benefit suicide prevention programs. International comparisons of registrations are lacking, however, and there is a need for systematically collected, high-quality data across countries. The current study investigated healthcare professionals' perceptions of registration practices and their suggestions for ensuring high-quality registration of self-harm and suicide attempts. METHODS: Qualitative interviews (N = 20) were conducted among medical secretaries, medical doctors, nurses, and registration advisers from psychiatric and somatic emergency departments in all regions of Denmark between September 2022 and March 2023. Content analysis was performed using NVivo. RESULTS: Despite great efforts to standardize and assure the quality of registration in Denmark, almost all the healthcare professionals perceived registration practice as inconsistent and unreliable. Codes are often misclassified or unused due to insufficient time, non-standardized training, or insufficient information. The interview informants suggested that coding guidelines should be simplified and made more visible, alongside technical solutions in the electronic health record system. CONCLUSION: The study findings resulted in eight overall recommendations for clinical practice that aim at improving the registration of patients presenting with self-harm or suicide attempts. This would be expected to help improve surveillance and prevention programs.

Profiles of suicide attempted in children and adolescents.

OBJECTIVE: Suicide attempt (SA) is the strongest predictive variable for completed suicide. The Department of Cauca in Colombia has an SA rate higher than the national average, but the factors are unknown. The objective was to identify the profiles of SA in children and adolescents of Cauca. METHODS: Cross-sectional study, which included all SA (Event-356) records from the SIVIGILA platform in children under 18 years of age between 2016 and 2019. The authors described the variables and multiple correspondence analysis (MCA) with the Burt method, according to the completeness of the data to establish the possible SA profiles using STATA 15.1, and R. The Ethics Committee at Universidad del Cauca approved it. RESULTS: The study found 977 SA during this period, 72.4% female, 97.1% adolescent, 74.4% mestizo, 19.3% indigenous, 45.3% resided in municipalities exposed to the armed conflict, 32.3% expressed ideation and previous attempts, and 15.5% prior attempts. The MCA included 810 SA and identified three profiles: "Classic", which had mestizo adolescents with a history of prior SA, mental illness, or psychoactive substance use problems; "Related to the armed conflict", which included female adolescents with a first SA and residents in municipalities exposed to the armed conflict; "Ethnic" represented by male indigenous, with housing in a rural area. CONCLUSION: The SA profiles found in Cauca were "Classic", "Related to the armed conflict", and "Ethnic"; these can be considered to implement prevention strategies from a cross-cultural, mental health, and gender perspective, with the presence of the state in the territories.

Characterization of suicidal behavior in Coquimbo, Chile, between 2018 and 2020. / Caracterización de la conducta suicida en población general de la Región de Coquimbo (Chile) entre 2018 y 2020.

Introduction: Suicidal behavior is a public health problem worldwide. The World Health Organization estimated 700 000 deaths for the year 2021. Objective: This study aimed to estimate the prevalence of suicidal behavior and describe its related factors in the Coquimbo Region, Chile, between 2018 and 2020. Methods: 2190 suicide attempt notifications from the regional epidemiological surveillance system were analyzed, corresponding to 1781 people, along with 217 reports from the Forensic Medical Service of people who died by suicide. Results: The overall suicide rate for the region during that period was 9.79 deaths per 100 000 inhabitants. The 2018 rates were standardized according to available information, with direct methods for the regional rate (9.55 per 100 000 inhabitants) and indirect methods for the communes. Rural communes presented higher rates than urban ones. Women showed a higher risk of attempts (OR 1.28; 95% CI 1.23 to 1.33) and a lower risk of suicide compared to men (0.086; 0.06 to 0.13). Young people had a higher risk of suicide attempts and a lower risk of suicide compared to older people. The increased suicide rates in older people (70 to 79 years) during 2020 are noteworthy. Basic education level is a risk variable for suicide (2.21; from 1.15 to 4.23), compared to having higher education. Previous suicide attempts and psychiatric pathology are risk factors. Conclusions: Suicide prevalence and related factors are similar to those reported in other studies and national reports, highlighting rurality and higher risk in older male adults. In contrast to suicides, attempts are more frequent in women and young people. A history of mental health problems, previous attempts, and family violence are risk factors for both outcomes. Knowing the patterns of suicidal behavior in the population is fundamental for its prevention.

Introducción: La conducta suicida es un problema de salud pública mundial. La Organización Mundial de la Salud estimó en 700 000 los fallecimientos por suicidio para el año 2021. Objetivo: El propósito fue estimar la prevalencia de la conducta suicida y describir sus factores relacionados en la Región de Coquimbo, Chile, entre los años 2018 y 2020. Métodos: Se analizaron 2190 notificaciones por intentos suicidas del sistema de vigilancia epidemiológica regional, que correspondieron a 1781 personas; junto con 217 informes de personas fallecidas por suicidio del Servicio Médico Legal. Resultados: La tasa global de suicidio para la región en el período fue de 9,79 fallecimientos por 100 000 habitantes. Se estandarizaron las tasas del año 2018 según la información disponible, con método directo para la tasa regional (9,55 por 100 000 habitantes) e indirecto para las comunas. Las comunas rurales presentaron mayores tasas que las urbanas. Las mujeres mostraron mayor riesgo de intentos (: 1,28; intervalo de confianza 95%: de 1,23 a 1,33) y menor riesgo de suicidio (0,086; de 0,06 a 0,13) que los hombres. Las personas jóvenes presentaron mayor riesgo de intentos y menor riesgo de suicidio, comparado con personas mayores. Destaca el aumento de la tasa de suicidio en personas mayores (de 70 a 79 años) durante el año 2020. El nivel educacional básico es una variable de riesgo para suicidio (2,21; de 1,15 a 4,23), comparado con educación universitaria. Los intentos de suicidio previos y patología psiquiátrica son factores de riesgo. Conclusiones: La prevalencia de suicidio y los factores relacionados son similares a lo reportado en otros estudios e informes nacionales, destacando la ruralidad y mayor riesgo en varones de edad adulta avanzada. A diferencia de los suicidios, los intentos son más frecuentes en mujeres y personas jóvenes. Antecedentes de problemas de salud mental, intentos previos y violencia en la familia son factores de riesgo para ambas conductas. Conocer el comportamiento de la conducta suicida en la población es fundamental para su prevención.

Ethnic and sexual orientation inequalities in mental health-obesity comorbidity, self-harm, and attempted suicide among British adolescents.

PURPOSE: Mental illness and obesity (MH-OB) may co-occur in adolescence and have a strong risk to track into adulthood. Using an intersectional framework, we explored associations between ethnic-sexual identities and MH-OB comorbidity in adolescents. We examined the risk of self-harm (SH) and attempted suicide (AS) by comorbidity status and ethnic-sexual identities. METHODS: Participants included 9,789 adolescents (aged 17 years) from the UK-wide Millennium Cohort Study with data on self-identified ethnicity and sexuality. Participants were categorised as White-heterosexual, White-sexual minority (SM), Ethnic Minority (EM) heterosexual or EM-SM adolescents. We used multivariable logistic regression to examine associations between 1.dual ethnic-sexual identities and MH-OB comorbidity, 2.risk for self-harm (or attempted suicide) in relation to comorbidity and ethnic-sexual identities (including interactions between the comorbidity and ethnic-sexual identities variables to assess whether risk for self-harm differed by ethnic-sexual identities and comorbidity status). RESULTS: Comorbidity was higher among White-SM (OR = 3.73, 95%CI 2.42-5.75) and EM-SM (OR = 1.96, 1.03-3.73) adolescents. SM identities (OR = 3.02, 2.41-3.78 for White-SM) and having comorbidity (OR = 2.83, 2.03-3.95) were independently associated with SH or AS. Risk of SH among White-heterosexual individuals was greater among comorbid individuals (40%) relative to non-comorbid individuals (19%). Risk of SH was higher in SM individuals (58% vs. 41% in White-SM and 50% vs. 29% in EM-SM individuals with and without comorbidity, respectively). Risk of AS was 5% and 19% in comorbid and non-comorbid White-heterosexual individuals, respectively; the corresponding figures for White-SM individuals were 14% and 17%. CONCLUSION: Irrespective of ethnicity, SM adolescents have a significantly greater risk of SH and AS. Comorbidity further amplifies this risk.

The relationship of the methylation status and polymorphism of glucocorticoid receptor gene (NR3C1) with attempted suicide or non-suicidal self-injury patients in schizophrenia.

We aim to investigate the methylation of NR3C1 gene promotor and NR3C1 BclI polymorphism in schizophrenia (SCZ) patients with attempted suicide or non-suicidal self-injury (NSSI). A sample of 112 patients with SCZ was included in the study. Structured Clinical Interview for Diagnostic and Statistical Manual-Fourth Edition Axis I Disorders was used to confirm the diagnosis according to The Diagnostic and Statistical Manual of Mental Disorders, fourth edition, text revision criteria. The patients were evaluated by data forms that had sociodemographic, suicidal behavior, and NSSI information. Methylation-specific polymerase chain reaction (PCR) was used to identify the methylation of the NR3C1 gene. The analysis of the BclI polymorphism of the NR3C1 gene was evaluated by using the PCR restriction fragment length polymorphism. Our results revealed that although the NR3C1 gene methylation was not statistically significantly different, there was a significant difference in NR3C1 genotype distribution among the SCZ groups with and without attempted suicide. SCZ patients carrying the CC genotype had a lower risk of attempted suicide (Odds Ratio [OR]: 0.421; 95% Confidence Interval [CI]: 0.183-0.970; p = 0.040), while having the GG genotype in SCZ patients was associated with a higher risk of attempted suicide (OR: 3.785; 95% Cl: 1.107-12.945; p = 0.042). Additionally, due to NSSI in SCZ patients, there were no significant differences in NR3C1 gene methylation and NR3C1 genotype distribution among the groups. We propose that the NR3C1 BclI polymorphism may be associated with attempted suicide in Turkish patients diagnosed with SCZ.

Psychometric properties and factor structure of the suicidal narrative inventory in major depression: A multicentric evaluation.

BACKGROUND: The Suicidal Narrative Inventory (SNI) is a 38-item self-report measure developed to assess elements of the suicidal narrative, a subacute, predominantly cognitive, presuicidal construct. Our objectives were to assess the factor structure, validity, and reliability of the SNI-38 among adults with major depressive disorder (MDD). METHODS: Using a cross-sectional design, we administered the Hindi version of the SNI along with other self-report measures to adults with MDD, recruited from 24 tertiary care hospitals across India. Confirmatory factor analysis (CFA) was performed to assess the factor structure of SNI-38. Reliability (internal consistency) was assessed using Cronbach's alpha (α). Convergent, discriminant, and criterion validity of the SNI-38 were tested by comparing it against other appropriate measures. RESULTS: We collected usable responses from 654 Hindi-speaking participants (Mean age = 36.9 ± 11.9 years, 50.2% female). The eight-factor solution of the SNI showed good model fit indices (χ2[637] = 3345.58, p <.001, CFI =.98, and RMSEA =.08). Internal consistencies for the SNI subscale scores were good to excellent, α ranging from .73 to.92. While most subscales significantly converged with other measures, associations were comparatively weaker and inconsistent for the 'thwarted belongingness' and 'goal reengagement' subscales. CONCLUSION: Consistent with prior data, our study confirmed an eight-factor solution and demonstrated adequate psychometric properties for the Hindi version of the SNI-38 in our sample. These findings provide empirical support for the use of SNI to assess the suicidal narrative among Indian adults with MDD.

Changes in severity of pediatric suicide attempts before and after coronavirus disease 2019.

BACKGROUND: The recent coronavirus disease 2019 (COVID-19) pandemic and school closures were reported to have negatively impacted the mental health of children and adolescents. This study aimed to examine the change in the number and severity of pediatric suicide attempts before and after the COVID-19 pandemic. METHODS: This study enrolled 54 patients (26 vs. 28 patients before and after the COVID-19 pandemic, respectively) under 19 years of age who were transported to the emergency department as a result of suicide attempts between April 2017 and December 2021. The primary outcome includes the rate of serious suicide attempts (SSAs). RESULTS: The SSA rates were 19% (5/26) and 43% (12/28) before and after the COVID-19 pandemic, respectively (p = 0.62). The average number of transported suicide attempts per month almost doubled (0.72 vs. 1.33, respectively) and suicide attempts as a percentage of all ambulance transportations of individuals under 19 years old increased significantly from 0.95% (26/2729)to 1.98% (28/1414) (p = 0.006). CONCLUSIONS: The COVID-19 pandemic increased the severity of pediatric suicide attempts but not to a statistically significant degree. Social preventive support and early psychological intervention are therefore needed currently and in the future.

The characteristics of suicide attempters in Chinese patients: Comparison of adolescents, youths, middle-aged and elderly.

BACKGROUND: Potential risk factors for suicide differ by age group. Therefore, this study aims to investigate the characteristics of patients with suicide attempts according to age group and any the relevant risk factors. METHODS: This study retrospectively reviewed the medical records of attempted suicide patients who were admitted to the emergency departments (ED) of the First Affiliated Hospital of Wenzhou Medical University between January 1, 2017, and December 31, 2021. Demographic information and clinical characteristics were collected. The participants were divided into four age groups and the characteristics of each group were compared. RESULTS: A total of 834 participants were included in this study. Suicide attempts were more prevalent in females, and the gender difference decreased with age. Having religious belief and less educated suicide attempts were concentrated in the elderly groups. Adolescents suicide attempts were more likely to occur in the spring, autumn and during non-office hours. Mental disorders were the major motivation for suicide among adolescents, and interpersonal and social problems were more prevalent among youths. Psychiatric medication was the leading suicidal substances among adolescents, while pesticides and herbicides were more prevalent in adults. The history of psychiatric diagnosis was more common in adolescents, while the history of somatic disorder was more prevalent in the elderly. CONCLUSION: This study confirmed differences in the demographic and clinical characteristics of patients in different age groups. Therefore, it is necessary to construct individualized intervention strategies for each age group based on the characteristics of the patients in order to reduce suicide.

Understanding the educational inequalities in suicide attempts and their mediators: a Mendelian randomisation study.

Background: Educational inequalities in suicide have become increasingly prominent over the past decade. Elucidating modifiable risk factors that serve as intermediaries in the impact of low educational attainment on suicide has the potential to reduce health disparities. Aims: To examine the risk factors that mediate the relationship between educational attainment and suicide attempts and quantify their contributions to the mediation effect. Methods: We conducted a two-sample Mendelian randomisation (MR) analysis to estimate the causal effect of educational attainment on suicide attempts, utilising genome-wide association study summary statistics from the Integrative Psychiatric Research (iPSYCH; 6024 cases and 44 240 controls) and FinnGen (8978 cases and 368 299 controls). We systematically evaluated 42 putative mediators within the causal pathway connecting reduced educational attainment to suicide attempts and employed two-step and multivariable MR to quantify the proportion of the mediated effect. Results: In the combined analysis of iPSYCH and FinnGen, each standard deviation (SD) decrease in genetically predicted educational attainment (equating to 3.4 years of education) was associated with a 105% higher risk of suicide attempts (odds ratio (OR): 2.05; 95% confidence interval (CI): 1.81 to 2.31). Of the 42 risk factors analysed, the two-step MR identified five factors that mediated the association between educational attainment and suicide attempts. The respective proportions of mediation were 47% (95% CI: 29% to 66%) for smoking behaviour, 36% (95% CI: 0% to 84%) for chronic pain, 49% (95% CI: 36% to 61%) for depression, 35% (95% CI: 12% to 59%) for anxiety and 26% (95% CI: 18% to 34%) for insomnia. Multivariable MR implicated these five mediators collectively, accounting for 68% (95% CI: 40% to 96%) of the total effect. Conclusions: This study identified smoking, chronic pain and mental disorders as primary intervention targets for attenuating suicide risk attributable to lower educational levels in the European population.

Prevalence of suicide attempt and associations with deliberate self-harm, mental health problems, drug misuse and traumatic experiences - a cross sectional survey of the Norwegian population.

BACKGROUND: Monitoring self-reported suicide attempts (SA) with nationally representative surveys is important to initiate suicide prevention strategies. The aim of the study was to assess the prevalence of SA and compare deliberate self-harm, (DSH), mental health, drug misuse and traumas between SA and non-suicide attempters (NSA). METHODS: In this cross-sectional survey of a representative sample (N=1757) of the Norwegian population, we compared people with self-reported SA (n=54) to NSA (n=1703) regarding sociodemographic data, mental health problems, drug misuse and exposure to trauma. RESULTS: The prevalence of SA was 3.1 %. There was a higher proportion of welfare recipients and more deliberate self-harm, mental health problems, drug misuse and traumas in the SA group compared to NSA. CONCLUSION: This national study confirms the association between suicide attempt and deliberate self-harm, mental health problems, drug misuse and traumas.

Health service and psychotropic medication use for mental health conditions among healthcare workers active during the Spain Covid-19 Pandemic - A prospective cohort study using web-based surveys.

Little is known about healthcare workers' (HCW) use of healthcare services for mental disorders. This study presents data from a 16-month prospective cohort study of Spanish HCW (n = 4,809), recruited shortly after the COVID-19 pandemic onset, and assessed at four timepoints using web-based surveys. Use of health services among HCW with mental health conditions (i.e., those having a positive screen for mental disorders and/or suicidal thoughts and behaviours [STB]) was initially low (i.e., 18.2 %) but increased to 29.6 % at 16-month follow-up. Service use was positively associated with pre-pandemic mental health treatment (OR=1.99), a positive screen for major depressive disorder (OR=1.50), panic attacks (OR=1.74), suicidal thoughts and behaviours (OR=1.22), and experiencing severe role impairment (OR=1.33), and negatively associated with being female (OR = 0.69) and a higher daily number of work hours (OR=0.95). Around 30 % of HCW with mental health conditions used anxiolytics (benzodiazepines), especially medical doctors. Four out of ten HCW (39.0 %) with mental health conditions indicated a need for (additional) help, with most important barriers for service use being too ashamed, long waiting lists, and professional treatment not being available. Our findings delineate a clear mental health treatment gap among Spanish HCW.
