Evaluating Population-Level Interventions and Exposures for Suicide Prevention.

Evaluations of interventions targeting the population level are an essential component of the policy development cycle. Pre-post designs are widespread in suicide prevention research but have several significant limitations. To inform future evaluations, our aim is to explore the three most frequently used approaches for assessing the association between population-level interventions or exposures and suicide - the pre-post design, the difference-in-difference design, and Poisson regression approaches. The pre-post design and the difference-in-difference design will only produce unbiased estimates of an association if there are no underlying time trends in the data and there is no additional confounding from other sources. Poisson regression approaches with covariates for time can control for underlying time trends as well as the effects of other confounding factors. Our recommendation is that the default position should be to model the effects of population-level interventions or exposures using regression methods that account for time effects. The other designs should be seen as fall-back positions when insufficient data are available to use methods that control for time effects.

Investigating changes in student mental health and help-seeking behaviour after the introduction of new well-being support services at a UK university.

BACKGROUND: Growing numbers of students now seek mental health support from their higher education providers. In response, a number of universities have invested in non-clinical well-being services, but there have been few evaluations of these. This research addresses a critical gap in the existing literature. AIMS: This study examined the impact of introducing non-clinical well-being advisers on student mental health and help-seeking behaviour at a large UK university. METHOD: Survey data collected pre-post service introduction in 2018 (n = 5562) and 2019 (n = 2637) measured prevalence of depression (Patient Health Questionnaire-9), anxiety (Generalised Anxiety Disorder-7), and low mental well-being (Warwick-Edinburgh Mental Wellbeing Scale), alongside student support-seeking behaviour. Logistic regression models investigated changes in outcome measures. Administrative data (2014-2020) were used to investigate corresponding trends in antidepressant prescribing at the onsite health service, student counselling referrals and course withdrawal rates. RESULTS: Adjusted models suggested reductions in students' levels of anxiety (odds ratio 0.86, 95% CI 0.77-0.96) and low well-being (odds ratio 0.84, 95% CI 0.75-0.94) in 2019, but not depression symptoms (odds ratio 1.05, 95% CI 0.93-1.17). Statistical evidence showed reduced student counselling referrals, with antidepressant prescribing and course withdrawal rates levelling off. Student perception of the availability and accessibility of university support improved. CONCLUSIONS: Our findings suggest a non-clinical well-being service model may improve student perception of support, influence overall levels of anxiety and low well-being, and reduce clinical need. The current study was only able to examine changes over the short term, and a longer follow-up is needed.

Travel Distance to Hospital Is Associated With Self-Harm Hospital Presentation But Not Suicide.

Background: Travel distance to hospital emergency departments (EDs) may be a more influential factor in the spatial variation in hospital-presenting self-harm than for suicide deaths. Aims: We investigated the associations of travel distance to the nearest ED with self-harm hospital presentations and suicides in a large city in Taiwan. Method: Data for self-harm and suicide were extracted from Taiwan's National Suicide Surveillance System (2012-2016). Results: Adjusted analyses using Bayesian hierarchical models showed that a longer travel distance to the nearest hospital ED was associated with lower self-harm hospital presentation rates but not suicide rates. Limitations: This is an ecological study; the area-level associations could not be directly implied at the individual level. Conclusion: Living in remote neighborhoods could be a barrier to seeking medical help after self-harm, and this has implications for suicide, surveillance, prevention and intervention strategies.

Suicidal Ideation and Behavior Among Mexican University Students Before and During the COVID-19 Pandemic.

OBJECTIVE: The COVID-19 pandemic has affected the mental health of populations around the world, but few longitudinal studies of its impact on suicidal thoughts and behaviors have been published especially from low- and middle-income countries. METHODS: This is a prospective cohort study of 1,385 first-year students from 5 Universities in Mexico followed-up for 1 year. We report 1-year cumulative incidence of suicidal thoughts and behaviors before (September 19, 2019-March 29, 2020) and during the COVID-19 period (March 30, 2020-June 30, 2020), focusing on those in the COVID-19 period with risk conditions and positive coping strategies during the pandemic. RESULTS: There was an increase in the incidence of suicidal ideation during the COVID-19 period compared to the pre-COVID-19 period (RR 1.65, 95%CI 1.08-2.50). This increase was mostly found among students with heightened sense of vulnerability (RR 1.95), any poor coping behavior (RR 2.40) and a prior mental disorder (RR 2.41). While we found no evidence of an increased risk of suicidal planning or attempts, there was evidence that those without lifetime mental health disorders were at greater risk of suicidal plans than those with these disorders especially if they had poor coping strategies (RR 3.14). CONCLUSION: In the short term, how students deal with the pandemic, being at high risk and having poor coping behavior, increased the new occurrence of suicidal thoughts and behaviors. Studies with longer follow-up and interventions to reduce or enhance these behaviors are needed.HIGHLIGHTSSuicidal ideation increased during the COVID-19 periodThose with heightened sense of vulnerability and poor coping were more affectedStudies with longer follow-up are needed.

Development of a Brief Intervention for Emergency Department Attendees Presenting With Self-Harm and Co-Occurring Substance Use Problems.

Background: People who present to the emergency department with self-harm and co-occurring substance use problems often have difficulty accessing effective care. Aims: To develop a brief psychosocial intervention for this population, which would be suitable for testing in a future randomized controlled trial. Methods: A modified Delphi method was used. A 34-item, 3-round, online Delphi survey was informed by a literature review and stakeholder telephone discussions (n = 17). Two panels consisting of people with lived experience (PWLE: n = 15) and people with occupational experience (PWOE: n = 21) participated in the survey. The threshold for consensus was a pooled agreement rate across the two panels of 80% or more. Results: Expert consensus was achieved for 22 items. The new intervention consists of weekly follow-up phone calls for up to 1 month, delivered by Liaison Psychiatry practitioners, in which both self-harm and substance use problems are explored and addressed, and patients are supported in accessing community services. Limitations: Some stakeholder ideas regarding intervention components could not be included as survey options due to anticipated difficulties with implementation. Conclusions: The key elements of a brief psychosocial intervention for self-harm and co-occurring substance use problems have been agreed. Feasibility testing is currently underway.

Differences in the characteristics of people who purchase pesticides from shops for self-harm versus those who use pesticides available in the domestic environment in Sri Lanka.

OBJECTIVE: Data from South Asia indicate that for 15%-20% of suicide attempts, pesticides are purchased from shops; otherwise, pesticides are obtained from an individual's house or nearby environment. We aimed to investigate the difference between individuals who directly purchase pesticides from shops for suicide attempts and suicide deaths versus those related to accessing the pesticides from an individual's house or nearby environment. METHODS: We conducted two comparative studies in rural Sri Lanka: (1) non-fatal shop cases (n = 50) were survivors of self-poisoning with pesticides who ingested the pesticides after purchasing them from a shop; non-fatal domestic cases (n = 192) were survivors who accessed pesticides from their house or nearby environment. (2) fatal shop cases (n = 50) were individuals who died after ingesting pesticides they purchased for the act; fatal domestic cases (n = 102) were patients who died after ingesting pesticides they accessed at house or nearby environment. Logistic regression analysis was used to assess the characteristics which distinguished between the shop and domestic cases. RESULTS: Data indicate that 20.7% and 32.9% of individuals who used pesticides for suicide attempts and suicide deaths had purchased them from shops, respectively. Being a non-farmer was the main distinguishing characteristic of shop cases: adjusted odds ratios (AOR) 8.9, 95% confidence intervals (CI) 3.2-24.4 for non-fatal shop cases, and AOR 4.0, 95% CI 1.5-10.6 for fatal shop cases. Non-fatal shop cases also had higher suicide intent (AOR 3.0, CI 1.0-8.9), and ingesting an insecticide (AOR 4.8, CI 1.8-1.0-8.9) than non-fatal domestic cases. CONCLUSION: A high suicide intent of individuals who purchase pesticides for the event explains the high proportion of such fatal cases. Such high suicide intent makes the prevention implications difficult to spell out for those individuals who purchase pesticides for self-poisoning. However, our findings are valuable for clinicians to assess pesticide poisoning cases in hospitals.

Antidepressants in pregnancy: applying causal epidemiological methods to understand service-use outcomes in women and long-term neurodevelopmental outcomes in exposed children.

Background: Antidepressants are commonly prescribed during pregnancy, despite a lack of evidence from randomised trials on the benefits or risks. Some studies have reported associations of antidepressants during pregnancy with adverse offspring neurodevelopment, but whether or not such associations are causal is unclear. Objectives: To study the associations of antidepressants for depression in pregnancy with outcomes using multiple methods to strengthen causal inference. Design: This was an observational cohort design using multiple methods to strengthen causal inference, including multivariable regression, propensity score matching, instrumental variable analysis, negative control exposures, comparison across indications and exposure discordant pregnancies analysis. Setting: This took place in UK general practice. Participants: Participants were pregnant women with depression. Interventions: The interventions were initiation of antidepressants in pregnancy compared with no initiation, and continuation of antidepressants in pregnancy compared with discontinuation. Main outcome measures: The maternal outcome measures were the use of primary care and secondary mental health services during pregnancy, and during four 6-month follow-up periods up to 24 months after pregnancy, and antidepressant prescription status 24 months following pregnancy. The child outcome measures were diagnosis of autism, diagnosis of attention deficit hyperactivity disorder and intellectual disability. Data sources: UK Clinical Practice Research Datalink. Results: Data on 80,103 pregnancies were used to study maternal primary care outcomes and were linked to 34,274 children with at least 4-year follow-up for neurodevelopmental outcomes. Women who initiated or continued antidepressants during pregnancy were more likely to have contact with primary and secondary health-care services during and after pregnancy and more likely to be prescribed an antidepressant 2 years following the end of pregnancy than women who did not initiate or continue antidepressants during pregnancy (odds ratioinitiation 2.16, 95% confidence interval 1.95 to 2.39; odds ratiocontinuation 2.40, 95% confidence interval 2.27 to 2.53). There was little evidence for any substantial association with autism (odds ratiomultivariableregression 1.10, 95% confidence interval 0.90 to 1.35; odds ratiopropensityscore 1.06, 95% confidence interval 0.84 to 1.32), attention deficit hyperactivity disorder (odds ratiomultivariableregression 1.02, 95% confidence interval 0.80 to 1.29; odds ratiopropensityscore 0.97, 95% confidence interval 0.75 to 1.25) or intellectual disability (odds ratiomultivariableregression 0.81, 95% confidence interval 0.55 to 1.19; odds ratiopropensityscore 0.89, 95% confidence interval 0.61 to 1.31) in children of women who continued antidepressants compared with those who discontinued antidepressants. There was inconsistent evidence of an association between initiation of antidepressants in pregnancy and diagnosis of autism in offspring (odds ratiomultivariableregression 1.23, 95% confidence interval 0.85 to 1.78; odds ratiopropensityscore 1.64, 95% confidence interval 1.01 to 2.66) but not attention deficit hyperactivity disorder or intellectual disability; however, but results were imprecise owing to smaller numbers. Limitations: Several causal-inference analyses lacked precision owing to limited numbers. In addition, adherence to the prescribed treatment was not measured. Conclusions: Women prescribed antidepressants during pregnancy had greater service use during and after pregnancy than those not prescribed antidepressants. The evidence against any substantial association with autism, attention deficit hyperactivity disorder or intellectual disability in the children of women who continued compared with those who discontinued antidepressants in pregnancy is reassuring. Potential association of initiation of antidepressants during pregnancy with offspring autism needs further investigation. Future work: Further research on larger samples could increase the robustness and precision of these findings. These methods applied could be a template for future pharmaco-epidemiological investigation of other pregnancy-related prescribing safety concerns. Funding: This project was funded by the National Institute for Health and Care Research (NIHR) Health Technology Assessment programme (15/80/19) and will be published in full in Health Technology Assessment; Vol. 27, No. 15.

About one in seven women experience depression during pregnancy. Left untreated, this may harm them and their unborn babies. However, the decision to take antidepressants during pregnancy is difficult because women often worry about the risks to their unborn baby. Research findings have been inconsistent, so women often do not have clear information to enable them to make informed decisions. We studied women's and children's outcomes after starting (compared with not starting) or continuing (compared with stopping) antidepressants in pregnancy. We used a large UK primary care database and several novel methods of analysis. We tracked 80,103 pregnancies of women with depression for up to 2 years after pregnancy. We also tracked 34,274 children from these pregnancies for at least 4 years to check for developmental outcomes. Women prescribed antidepressants were more likely than women not prescribed antidepressants to use general practice and mental health services during and after pregnancy, and to be prescribed antidepressants 2 years after pregnancy. This suggests that antidepressants were being prescribed to women with greater clinical need. Women who continued antidepressants in pregnancy had no higher likelihood than those who discontinued antidepressants of autism, attention deficit hyperactivity disorder or intellectual disability in their children. This should reassure women making the decision to continue taking their medications in pregnancy. Women who started antidepressants in pregnancy may possibly have had a slightly higher likelihood of autism in their children than those who did not start them. These findings were not seen in all analyses and were based on smaller numbers; therefore, they should be viewed with caution. Importantly, over 98 in every 100 children of women who initiated or continued antidepressants in pregnancy did not receive an autism diagnosis. The findings may help women and clinicians make informed decisions on treatment with antidepressants in pregnancy.

Understanding Suicide Clusters Through Exploring Self-Harm Behaviors.

Background: There is little information about characteristics and long-term outcomes of individuals who self-harm during a suicide cluster. Aims: To compare characteristics of individuals who self-harmed during a suicide cluster in South Wales (∼10 deaths between December 2007 and March 2008) with others who self-harmed prior to the cluster and to evaluate 10-year self-harm and mortality outcomes. Method: Using records from the hospital serving the catchment area of the suicide cluster, enhanced by national routinely collected linked data, we created the following two groups: individuals who self-harmed (a) during the suicide cluster and (b) 1 year before. We compared individuals' characteristics and performed logistic regression to compute odds ratios of 10-year self-harm and mortality outcomes. Results: Individuals who self-harmed during the cluster were less likely to be hospitalized or have a mental health history than those who self-harmed prior to the cluster. No significant group differences were found for 10-year self-harm outcomes, but all-cause mortality was higher for males. Limitations: Sample size was small, and data were lacking on psychological and social proximity to individuals who died during the suicide cluster. Conclusion: Our findings highlight the importance of long-term healthcare follow-up of those who self-harm during a suicide cluster, particularly males.

A narrative review of recent tools and innovations toward automating living systematic reviews and evidence syntheses.

Living reviews are an increasingly popular research paradigm. The purpose of a 'living' approach is to allow rapid collation, appraisal and synthesis of evolving evidence on an important research topic, enabling timely influence on patient care and public health policy. However, living reviews are time- and resource-intensive. The accumulation of new evidence and the possibility of developments within the review's research topic can introduce unique challenges into the living review workflow. To investigate the potential of software tools to support living systematic or rapid reviews, we present a narrative review informed by an examination of tools contained on the Systematic Review Toolbox website. We identified 11 tools with relevant functionalities and discuss the important features of these tools with respect to different steps of the living review workflow. Four tools (NestedKnowledge, SWIFT-ActiveScreener, DistillerSR, EPPI-Reviewer) covered multiple, successive steps of the review process, and the remaining tools addressed specific components of the workflow, including scoping and protocol formulation, reference retrieval, automated data extraction, write-up and dissemination of data. We identify several ways in which living reviews can be made more efficient and practical. Most of these focus on general workflow management, or automation through artificial intelligence and machine-learning, in the screening process. More sophisticated uses of automation mostly target living rapid reviews to increase the speed of production or evidence maps to broaden the scope of the map. We use a case study to highlight some of the barriers and challenges to incorporating tools into the living review workflow and processes. These include increased workload, the need for organisation, ensuring timely dissemination and challenges related to the development of bespoke automation tools to facilitate the review process. We describe how current end-user tools address these challenges, and which knowledge gaps remain that could be addressed by future tool development. Dedicated web presences for automatic dissemination of in-progress evidence updates, rather than solely relying on peer-reviewed journal publications, help to make the effort of a living evidence synthesis worthwhile. Despite offering basic living review functionalities, existing end-user tools could be further developed to be interoperable with other tools to support multiple workflow steps seamlessly, to address broader automatic evidence retrieval from a larger variety of sources, and to improve dissemination of evidence between review updates.

Space-time self-harm and suicide clusters in two cities in Taiwan.

AIMS: Suicidal acts may cluster in time and space and lead to community concerns about further imitative suicidal episodes. Although suicide clusters have been researched in previous studies, less is known about the clustering of non-fatal suicidal behaviour (self-harm). Furthermore, most previous studies used crude temporal and spatial information, e.g., numbers aggregated by month and residence area, for cluster detection analysis. This study aimed to (i) identify space-time clusters of self-harm and suicide using daily incidence data and exact address and (ii) investigate the characteristics of cluster-related suicidal acts. METHODS: Data on emergency department presentations for self-harm and suicide deaths in Taipei City and New Taipei City, Taiwan, were used in this study. In all-age and age-specific analyses, self-harm and suicide clusters were identified using space-time permutation scan statistics. A cut-off of 0.10 for the p value was used to identify possible clusters. Logistic regression was used to investigate the characteristics associated with cluster-related episodes. RESULTS: A total of 5,291 self-harm episodes and 1,406 suicides in Taipei City (2004-2006) and 20,531 self-harm episodes and 2,329 suicides in New Taipei City (2012-2016) were included in the analysis. In the two cities, two self-harm clusters (n [number of self-harm episodes or suicide deaths in the cluster] = 4 and 8 in Taipei City), four suicide clusters (n = 3 in Taipei City and n = 4, 11 and 4 in New Taipei City) and two self-harm and suicide combined clusters (n = 4 in Taipei City and n = 8 in New Taipei City) were identified. Space-time clusters of self-harm, suicide, and self-harm and suicide combined accounted for 0.05%, 0.59%, and 0.08% of the respective groups of suicidal acts. Cluster-related episodes of self-harm and suicide were more likely to be male (adjusted odds ratio [aOR] = 2.22, 95% confidence interval [CI] 1.26, 3.89) and young people aged 10-29 years (aOR = 2.72, 95% CI 1.43, 5.21) than their cluster-unrelated counterparts. CONCLUSIONS: Space-time clusters of self-harm, suicide, and self-harm and suicide combined accounted for a relatively small proportion of suicidal acts and were associated with some sex/age characteristics. Focusing on suicide deaths alone may underestimate the size of some clusters and/or lead to some clusters being overlooked. Future research could consider combining self-harm and suicide data and use social connection information to investigate possible clusters of suicidal acts.

Conceptualising the commercial determinants of suicide: broadening the lens on suicide and self-harm prevention.

Suicide is preventable, yet, in many settings, robust suicide prevention strategies have not been implemented. Although a commercial determinants of health lens is increasingly being applied to industries important to the field of suicide prevention, the interplay between the vested interests of commercial actors and suicide has received little attention. There is a need to shift attention to the causes of the causes, directing more focus to the ways that commercial determinants influence suicide and shape suicide prevention strategies. Such a shift in perspective, with an evidence base and precedents to draw upon, has transformative potential for research and policy agendas dedicated to understanding and addressing upstream modifiable determinants of suicide and self-harm. We propose a framework intended to help guide efforts to conceptualise, research, and address the commercial determinants of suicide and their inequitable distribution. We hope these ideas and lines of inquiry help to catalyse connections between disciplines and open further debate and discussion as to how to take such an agenda forward.

All-Cause and Cause-Specific Mortality in Parents After the Death of a Child in Taiwan: A Population-Based Cohort Study.

OBJECTIVE: Research from Western countries suggests that there is an increase in mortality in parents bereaved by the death of a child. Few studies have investigated this issue in a non-Western context. We explored the impact of the death of a child on parental mortality in Taiwan. METHOD: By linking population-based national registers, we followed the 2004-2014 birth cohort ( N = 2,083,972) up until 2016. A total of 11,755 child deaths were identified. For each deceased child, four living children matched on age and sex were randomly selected; their parents were the comparison group. We used Cox proportional hazards regression models to compare the mortality risk of bereaved parents with the comparison group up until 2017. RESULTS: Overall mortality risk was increased in parents who experienced the death of a child; the risk was higher in bereaved mothers (adjusted hazard ratio = 4.91, 95% confidence interval = 3.96-6.09) than fathers (adjusted hazard ratio = 1.82, 95% confidence interval = 1.55-2.13). The risk did not differ according to the sex of the child, but parents whose children died of unexpected causes (i.e., suicide/accidents/violence) were at greater risk than those dying of other causes. Risk was higher when the child was older than 1 year at the time of death than for deaths before age 1 year. CONCLUSIONS: Parents who lost a child were at increased mortality risk in this East Asian population. Special attention should be paid to the health of bereaved parents and explore the pathways leading to their risk.

The Impact of the COVID-19 Pandemic and Lockdowns on Self-Poisoning and Suicide in Sri Lanka: An Interrupted Time Series Analysis.

Evidence from high-income countries suggests that the impact of COVID-19 on suicide and self-harm has been limited, but evidence from low- and middle-income countries is lacking. Using data from a hospital-based self-poisoning register (January 2019-December 2021) and data from national records (2016-2021) of suicide in Sri Lanka, we aimed to assess the impact of the pandemic on both self-poisoning and suicide. We examined changes in admissions for self-poisoning and suicide using interrupted time series (ITS) analysis. For the self-poisoning hospital admission ITS models, we defined the lockdown periods as follows: (i) pre-lockdown: 01/01/2019-19/03/2020; (ii) first lockdown: 20/03/2020-27/06/2020; (iii) post-first lockdown: 28/06/2020-11/05/2021; (iv) second lockdown: 12/05/2021-21/06/2021; and (v) post-second lockdown: 22/06/2021-31/12/2021. For suicide, we defined the intervention according to the pandemic period. We found that during lockdown periods, there was a reduction in hospital admissions for self-poisoning, with evidence that admission following self-poisoning remained lower during the pandemic than would be expected based on pre-pandemic trends. In contrast, there was no evidence that the rate of suicide in the pandemic period differed from that which would be expected. As the long-term socioeconomic impacts of the pandemic are realised, it will be important to track rates of self-harm and suicide in LMICs to inform prevention.

Emotional dysregulation in childhood and disordered eating and self-harm in adolescence: prospective associations and mediating pathways.

BACKGROUND: Emotional dysregulation may be a risk factor for disordered eating and self-harm in young people, but few prospective studies have assessed these associations long-term, or considered potential mediators. We examined prospective relationships between childhood emotional dysregulation and disordered eating and self-harm in adolescence; and social cognition, emotional recognition, and being bullied as mediators. METHODS: We analysed Avon Longitudinal Study of Parents and Children data on 3,453 males and 3,481 females. We examined associations between emotional dysregulation at 7 years and any disordered eating and any self-harm at 16 years with probit regression models. We also assessed whether social cognition (7 years), emotional recognition (8 years) and bullying victimisation (11 years) mediated these relationships. RESULTS: Emotional dysregulation at age 7 years was associated with disordered eating [fully adjusted probit B (95% CI) = 0.082 (0.029, 0.134)] and self-harm [fully adjusted probit B (95% CI) = 0.093 (0.036, 0.150)] at age 16 years. There was no evidence of sex interactions or difference in effects between self-harm and disordered eating. Mediation models found social cognition was a key pathway to disordered eating (females 51.2%; males 27.0% of total effect) and self-harm (females 15.7%; males 10.8% of total effect). Bullying victimisation was an important pathway to disordered eating (females 17.1%; males 10.0% of total effect), but only to self-harm in females (15.7% of total effect). Indirect effects were stronger for disordered eating than self-harm. CONCLUSIONS: In males and females, emotional dysregulation in early childhood is associated with disordered eating and self-harm in adolescence and may be a useful target for prevention and treatment. Mediating pathways appeared to differ by sex and outcome, but social cognition was a key mediating pathway for both disordered eating and self-harm.

Societal factors and psychological distress indicators associated with the recent rise in youth suicide in Taiwan: A time trend analysis.

OBJECTIVE: We investigated recent trends in youth suicide and their associations with societal and psychological factors in Taiwan. METHODS: Suicide data (1971-2019) for 10-24 year olds were extracted from Taiwan's national cause-of-death data files. We investigated changes in trends in youth suicide rates, societal factors (gross domestic product per capita, Gini index, overall and youth unemployment rates, divorce rates in people aged 40-59 years [i.e. the age of most 15-24 year olds' parents] and Internet use rates) and psychological distress indicators (youth self-harm rates and the prevalence of worry-related insomnia, and suicide ideation, plan and attempt) using joinpoint regression and graphic examinations. The associations of these factors with youth suicide rates were examined using Prais-Winsten regression. RESULTS: Suicide rates in Taiwan's 10-24 year olds changed from a downward trend (2005-2014) to an upward trend in 2014 and increased 11.5% (95% confidence interval = [5.2%, 18.1%]) annually between 2014 and 2019. There was also an upturn in divorce rates among females aged 40-59 years in 2014 and self-harm rates among 15- to 24-year-old youth in 2013. The prevalence of self-reported insomnia and suicide ideation, plan and attempt in youth started to increase from 2013 to 2016. In the regression analysis, Internet use, female divorce rates and youth self-harm rates were positively associated with youth suicide rates. CONCLUSION: Suicide rates and the prevalence of suicidal behaviors began to increase in Taiwanese youth in the 2010s. These increases may be associated with concurrent rises in parental divorce rates, Internet use and poor sleep. Further research is needed to examine the mechanisms underlying recent increases in youth suicide risk.

"I Can't See an End in Sight." How the COVID-19 Pandemic May Influence Suicide Risk.

Background: The COVID-19 pandemic and its consequences may affect population mental health and suicide risk. Aims: To explore the experiences among suicidal individuals who made calls to a suicide prevention hotline and to identify factors and psychological responses that may influence suicide risk. Method: We identified 60 eligible recorded calls to Taiwan's suicide prevention hotline (January 23, 2020-May 31, 2020) and analyzed the transcripts using a framework analysis. Results: We identified three themes: (a) effects of the COVID-19 pandemic on society (impacts on local economies, the fear of contagion, and disruptions caused by outbreak control measures); (b) stress experienced by callers, including increased challenges (financial burden, restricted freedom of movement, interpersonal conflicts, feelings of uncertainty, and education/career interruption) and reduced support (reduced access to health services and social support); and (c) the callers' psychological responses to stress, including anxiety, sleep disturbance, depression, loneliness, hopelessness, and entrapment, which may increase suicide risk. Limitations: Only the experiences among those who sought help by calling the hotline during the early months of the pandemic in 2020 were explored. Conclusion: Our findings revealed the potential process underlying the impact of the COVID-19 pandemic on suicide risk and have implications for prevention and intervention strategies.

The Impact of the COVID-19 Pandemic on Calls to a National Suicide Prevention Hotline in Taiwan: An Analysis of Time Trend and Characteristics of Calls.

We investigated the impact of the COVID-19 pandemic on call volumes and call characteristics using data from a national crisis helpline. Data were extracted for 215,066 calls to Taiwan's national suicide prevention hotline (January 2018-May 2020). We used negative binomial regression to investigate changes in the weekly number of calls during the early period of the COVID-19 outbreak (January 21, 2020-May 25, 2020), relative to that expected according to the pre-pandemic trend. The call characteristics during the pandemic period (February 18, 2020-May 31, 2020) were compared between COVID-19 related vs unrelated calls. Higher-than-expected call volumes started from the 6th week of the pandemic and reached a peak in the 14th week, which was 38% (rate ratio = 1.38, 95% confidence interval 1.26-1.51) higher than that expected based on the pre-pandemic trend. The higher-than-expected call volumes were mainly attributable to higher-than-expected calls from non-suicidal and male callers. Calls in which COVID-19 was mentioned (13.2%) were more likely to be from male and first-time callers, occur outside 12 am-6 am, last less than 5 min, and were less likely to be from callers who had previous suicide attempts, recent suicidal ideation or suicide plans or actions than COVID-19 unrelated calls. Callers who made COVID-19 related calls were more likely to request information than other callers. Crisis helplines should strategically adapt to the increased need and callers' specific concerns related to the outbreak.
