Academic psychiatry is essential for advancing mental health understanding and treatments. However, women encounter more obstacles hindering their progress in academia than men. This Editorial aims to highlight these obstacles and propose strategies to address them, advocating for a more supportive environment for women psychiatrists’ ongoing growth and development. The importance of supportive environments, fair access to opportunities and structural changes, including initiatives for mentorship, funding and flexible work arrangements, are crucial. Collaboration among governments, institutions and organisations is needed to enhance research infrastructure and promote gender equality. Encouraging and recognising women's contributions in research fosters inclusivity and innovation. Prioritising these efforts is vital for the existence, well-being and success of women in academic psychiatry.

According to the World Health Organization (WHO), more than 700,000 people take their own life every year globally. WHO also estimates that for every suicide, there are at least 10–20 acts of self-harm and about a hundred people have suicidal thoughts. Every suicide affects a large number of people in the victims immediate and extended circle of family, friends and work colleagues. Suicide is aetiologically heterogeneous and occurs due to convergence of a broad spectrum of individual and non-individual risk factors, with significant differences in its patterns across gender, age, culture, geographical location, and personal history. Society and culture have a significant impact on how people view and relate to mental illness and suicide. Culture, in particular, influences the psychopathology of suicidal behaviour and its impact on suicide rates across the world is well established. This is of high relevance to the understanding and assessment of people in a suicidal crisis, as they are influenced by deep-rooted traditions of suicidal behaviour in their culture of origin. Although there has been significant progress in our understanding on the underlying mechanisms that contribute to suicidal behaviours, there is much that we do not know. In particular, we need better understanding of how culture shapes the perception and experience of suicidal behaviours in different societies around the world.

Background Most evidence on suicidal thoughts, plans and attempts comes from Western countries; prevalence rates may differ in other parts of the world. Aims This study determined the prevalence of suicidal thoughts, plans and attempts in high school students in three different regional settings in Kenya. Method This was a cross-sectional study of 2652 high school students. We asked structured questions to determine the prevalence of various types of suicidality, the methods planned or effected, and participants’ gender, age and form (grade level). We provided descriptive statistics, testing significant differences by chi-squared and Fisher's exact tests, and used logistic regression to identify relationships among different variables and their associations with suicidality. Results The prevalence rates of suicidal thoughts, plans and attempts were 26.8, 14.9 and 15.7%, respectively. These rates are higher than those reported for Western countries. Some 6.7% of suicide attempts were not associated with plans. The most common method used in suicide attempts was drinking chemicals/poison (18.8%). Rates of suicidal thoughts and plans were higher for older students and students in urban rather than rural locations, and attempts were associated with female gender and higher grade level – especially the final year of high school, when exam performance affects future education and career prospects. Conclusion Suicidal thoughts, plans and attempts are prevalent in Kenyan high school students. There is a need for future studies to determine the different starting points to suicidal attempts, particularly for the significant number whose attempts are not preceded by thoughts and plans.

Background Climate change has psychological impacts but most of the attention has been focused on the physical impact. This study was aimed at determining the association of climate change with adolescent mental health and suicidality as reported by Kenyan high school students. Methods This was a cross sectional study with a sample size of 2,652. The participants were high school students selected from 10 schools in 3 regions of Kenya. A questionnaire was used to assess climate change experiences, mental health problems, and suicidality of the youth. Data were analyzed descriptively and with logistic regression to determine various associations of the different variables and the predictors of the various scores of SDQ and suicidality at 95% CI. Results Significant differences were observed between gender and two of the threats of climate change – worry and being afraid as subjectively experienced by the participants. Females were more worried and afraid of climate change than males. On univariate and multivariate logistic regression, we found that various experiences of climate change were significantly associated with various scores of SDQ and much fewer of the experiences predicted SDQ scores. The same pattern was reflected in suicidality. Conclusion Climate change appears to be associated with mental health concerns and suicidality according to Kenyan high school students’ reports with gender differences in some associations.

BACKGROUND Menstrual symptoms are predominantly studied among adults but may occur directly after menarche. Adolescent menstrual healthcare, however, faces specific obstacles and more research into menstrual symptoms as a determinant of adolescent well-being is therefore advocated. OBJECTIVE This study aimed to investigate menstrual symptoms and their impact on everyday life and well-being among postmenarchal adolescents. STUDY DESIGN A survey was delivered to a random sample of 1644 schoolgirls, drawn from a population-based project involving 116 lower secondary education schools (7th and 8th grade) in Stockholm, Sweden. Menstrual symptoms (ie, dysmenorrhea, heavy bleeding, irregular periods, mood disturbance, other general symptoms) were investigated through multiple choice questions and defined according to their impact on everyday life as mild (seldom affected), moderate (affected but possible to cope) and severe (affected and difficult to cope). Subjective well-being was measured with the World Health Organization Five Well-Being index. Postmenarchal respondents were eligible for analysis; those with incomplete outcome data or using hormonal contraception were excluded. The frequency and severity of symptoms across different postmenarchal years (1st, 2nd, 3rd, 4th, or 5th+ year after menarche) were studied with Chi-square and Kendall's tau statistics. Analysis of variance was used to study the association between menstrual symptoms and World Health Organization Five Well-Being index scores. A composite menstrual health index variable was obtained through principal component analysis and used to study the overall impact of menstrual symptoms on well-being in regression analyses. RESULTS Of 1100 postmenarchal girls (mean age, 14.1±0.7 years), 93.2% reported menstrual symptoms, 81.3% had at least 1 moderate symptom and 31.3% had at least 1 severe symptom. The most frequent symptoms were dysmenorrhea (80.4%) and mood disturbance (81.1%), followed by irregular periods (67.9%), heavy bleeding (60.4%), and other general symptoms (60.4%). Throughout postmenarchal years, there was a significant increase in frequency and severity (P<.001) of dysmenorrhea (τ=0.148), heavy bleeding (τ=0.134), mood disturbance (τ=0.117), and other general symptoms (τ=0.110), but not irregular periods (τ=−0.0201; P=.434). Girls with menstrual symptoms had significantly lower World Health Organization Five Well-Being index scores than those without symptoms (mean difference, −17.3; 95% confidence interval, −22.4 to −12.3). Analysis of variance showed significant associations (P<.001) with World Health Organization Five Well-Being index scores for each of the examined menstrual symptoms. In post hoc pairwise comparisons with peers without symptoms, the greatest reductions in World Health Organization Five Well-Being index score were found among girls with severe symptoms (mean difference for: dysmenorrhea, −20.72; heavy bleeding, −15.75; irregular periods, −13.81; mood disturbance, −24.97; other general symptoms, −20.29), but significant differences were observed even for moderate or mild symptoms. The composite menstrual health index was significantly associated with World Health Organization Five Well-Being index scores in regression analysis, independently of age, age at menarche, body mass index, smoking, physical activity, own and parental country of birth, biparental care, and socioeconomic status. CONCLUSION Despite growing awareness about the relevance of menstruation to women's health, unmet menstrual health needs are a potential threat to the well-being of adolescents. Education, screening, and clinical competence are important tools to reduce the burden of menstrual symptoms during adolescence and to prevent long-term consequences. The development of novel person-centered strategies should be a priority for clinical practice and research in adolescent menstrual health.

Suicide is a global issue accounting for more than 700,000 deaths annually, with low- and middle-income countries being disproportionally affected. Technology-enhanced interventions have been suggested as a preventive method with various benefits—e.g., increased scalability and sustainability, making them relevant for developed and especially for developing nations. However, despite the increasing number of such interventions, their effectiveness is seldom appropriately evaluated. The current review aims to tackle this need by synthetizing the evidence with the goal of answering whether these interventions can be recommended for the self-management of suicidality. A systematic review was carried out across multiple databases (PubMed/Medline, Global Index Medicus, PsychINFO, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, and Cumulative Index to Nursing and Allied Health Literature), identifying 4520 individual reports up to November 2021. Ten of these were deemed sufficient to inform the evaluation, but only four were included in the meta-analyses. Quality assessment via GRADE reveals some concerns, primarily regarding selection of reported results. Results suggest negligible effect on the outcomes of deaths by suicide, suicide attempts, and a small effect on suicidal ideation—favoring digital interventions over no intervention. Conclusively, there is not enough evidence to allow for the recommendation of digital interventions as stand-alone care, but they are promising if developed on the grounds of evidence-based practices. The review also highlights the challenges of evaluation, by discussing excessive safety procedures and considering parallelly ongoing treatment. Additionally, the need to involve low- and middle-income countries is emphasized as currently these regions are underrepresented, even though they have a high potential for benefiting from stand-alone digital interventions.

Objective To investigate behavioral sleep habits, self-perceived quality of sleep, and chronotype, and to examine their association with clinically relevant levels of depression in Swedish adolescents. Method Questionnaire data were obtained from a representative sample of Swedish adolescents (n = 8449; 50.8% girls; aged 12–16). Depression was defined as >13 BDI-II scores. Logistic regression modelling estimated the effects of sleep duration, sleep quality, and chronotype on depression, adjusted for socio-demographic factors. Results On weekdays, approximately 46% of adolescents slept less than the recommended length of eight hours per night (depressed: 68%, non-depressed: 40%). On weekends, however, only 17% slept shorter than recommended. Short weekday sleep duration was more common among girls than boys (53% vs. 38%) and girls reported worse sleep quality. The regression model showed that depression was predicted by weekday sleep duration (OR = 0.773, p < .0001), sleep quality (OR = 0.327, p < .0001), and late chronotype (OR = 1.126, p = .0017), but not by weekend sleep duration. A 30-minute increase in weekday sleep duration was associated with about 10% lower odds of depression. Conclusions A substantial proportion of Swedish adolescents do not seem to meet the sleep recommendations of eight hours per night. Short sleep duration on weekdays, poor sleep quality, and late chronotype were associated with increased risk of depression. Interventions promoting longer weekday sleep duration (e.g., later school start times) seem relevant in this context, but further research is needed to investigate the directionality and underlying mechanisms of these associations.

Background The European Psychiatric Association (EPA) is an organization that speaks on behalf of its individual members and members of National Psychiatric Associations (NPAs). The aim of this study to identify and investigate current contents of ethical codes and practices in the countries belonging to EPA. Methods The study is an expert survey sent out to 44 representatives of 30 NPAs covering the following topics: the existence of national bodies dealing with ethical issues in psychiatry, the availability of documents relevant to ethical issues, the types of ethical issues addressed at the national level, and the current and envisaged ethical debates. Results Out of 44 experts invited to participate in the study, 31 NPAs from 30 countries responded (response rate 70.45%). In the majority of countries, the general mission statement serves as the main document covering ethical issues in psychiatry. Most frequently, internal documents were reported to address medical malpractice, workplace bullying, plagiarism, academic fraud, sexual abuse, and discrimination/racism. Furthermore, internal documents cover the ethical assessment of potentially controversial procedures, including psychosurgery, euthanasia, and pregnancy termination. The most important topics for debate at the level of NPAs/EPA were associated with violations of clinical practice standards and human rights. Conclusions NPAs are active in the field of professional ethics, defining ethical standards related to interactions among professionals and services provided by mental health care professionals. Future collaboration of NPAs, under the umbrella of the EPA, could allow to develop a database of local ethical documents that would be translated into English and accessible to all EPA members.

Objective: Suicidal behavior is heritable and is a major cause of death worldwide. Two large-scale genome-wide association studies (GWASs) recently discovered and cross-validated genome-wide significant (GWS) loci for suicide attempt (SA). The present study leveraged the genetic cohorts from both studies to conduct the largest GWAS meta-analysis of SA to date. Multi-ancestry and admixture-specific meta-analyses were conducted within groups of significant African, East Asian, and European ancestry admixtures. Methods: This study comprised 22 cohorts, including 43,871 SA cases and 915,025 ancestry-matched controls. Analytical methods across multi-ancestry and individual ancestry admixtures included inverse variance-weighted fixed-effects meta-analyses, followed by gene, gene-set, tissue-set, and drug-target enrichment, as well as summary-data-based Mendelian randomization with brain expression quantitative trait loci data, phenome-wide genetic correlation, and genetic causal proportion analyses. Results: Multi-ancestry and European ancestry admixture GWAS meta-analyses identified 12 risk loci at p values <5×10-8. These loci were mostly intergenic and implicated DRD2, SLC6A9, FURIN, NLGN1, SOX5, PDE4B, and CACNG2. The multi-ancestry SNP-based heritability estimate of SA was 5.7% on the liability scale (SE=0.003, p=5.7×10-80). Significant brain tissue gene expression and drug set enrichment were observed. There was shared genetic variation of SA with attention deficit hyperactivity disorder, smoking, and risk tolerance after conditioning SA on both major depressive disorder and posttraumatic stress disorder. Genetic causal proportion analyses implicated shared genetic risk for specific health factors. Conclusions: This multi-ancestry analysis of suicide attempt identified several loci contributing to risk and establishes significant shared genetic covariation with clinical phenotypes. These findings provide insight into genetic factors associated with suicide attempt across ancestry admixture populations, in veteran and civilian populations, and in attempt versus death.
