Recent evidence from case reports suggests that a ketogenic diet may be effective for bipolar disorder. However, no clinical trials have been conducted to date.

To assess the recruitment and feasibility of a ketogenic diet intervention in bipolar disorder.

Euthymic individuals with bipolar disorder were recruited to a 6–8 week trial of a modified ketogenic diet, and a range of clinical, economic and functional outcome measures were assessed. Study registration number: ISRCTN61613198.

Of 27 recruited participants, 26 commenced and 20 completed the modified ketogenic diet for 6–8 weeks. The outcomes data-set was 95% complete for daily ketone measures, 95% complete for daily glucose measures and 95% complete for daily ecological momentary assessment of symptoms during the intervention period. Mean daily blood ketone readings were 1.3 mmol/L (s.d. = 0.77, median = 1.1) during the intervention period, and 91% of all readings indicated ketosis, suggesting a high degree of adherence to the diet. Over 91% of daily blood glucose readings were within normal range, with 9% indicating mild hypoglycaemia. Eleven minor adverse events were recorded, including fatigue, constipation, drowsiness and hunger. One serious adverse event was reported (euglycemic ketoacidosis in a participant taking SGLT2-inhibitor medication).

The recruitment and retention of euthymic individuals with bipolar disorder to a 6–8 week ketogenic diet intervention was feasible, with high completion rates for outcome measures. The majority of participants reached and maintained ketosis, and adverse events were generally mild and modifiable. A future randomised controlled trial is now warranted.

A core element of the Strengthening Responses to Dementia in Developing Countries (STRiDE) programme was to generate novel data on the prevalence, cost and impact of dementia in low- and middle-income countries, to build better health policy. Indonesia and South Africa are two middle-income countries in need of such data.

To present the STRiDE methodology and generate estimates of dementia prevalence in Indonesia and South Africa.

We conducted community-based, single-phase, cross-sectional studies in Indonesia and South Africa, randomly sampling participants aged 65 years or older in each country. Dementia prevalence rates for each country were generated by using the 10/66 short schedule and applying its diagnostic algorithm. Weighted estimates were calculated with national sociodemographic data.

Data were collected between September and December 2021 in 2110 people in Indonesia and 408 people in South Africa. The adjusted weighted dementia prevalence was 27.9% (95% CI 25.2–28.9) in Indonesia and 12.5% (95% CI 9.5–16.0) in South Africa. Our results indicate that there could be >4.2 million people in Indonesia and >450 000 people in South Africa who have dementia. Only five participants (0.2%) in Indonesia and two (0.5%) in South Africa had been previously diagnosed with dementia.

Despite prevalence estimates being high, formal diagnosis rates of dementia were very low across both countries (<1%). Further STRiDE investigations will provide indications of the impact and costs of dementia in these countries, but our results provide evidence that dementia needs to be prioritised within national health and social care policy agendas.

The COVID-19 pandemic has affected perinatal mental health. Reliable tools are needed to assess perinatal stress during pandemic situations.

To assess the psychometric properties of the Greek versions of the Pandemic-Related Pregnancy Stress Scale (PREPS) and the Pandemic-Related Postpartum Stress Scale (PREPS-PP) and to explore the associations between women's characteristics and perinatal stress during the second pandemic wave.

The PREPS and PREPS-PP were completed by 264 pregnant and 188 postpartum women, respectively, who also completed the State-Trait Anxiety Inventory (STAI) and the Edinburgh Perinatal Depression Scale (EPDS).

The internal consistency was similar for PREPS and PREPS-PP. It was good for preparedness stress (a = 0.77 and α = 0.71, respectively) and infection stress (α = 0.83 for both scales) but low for positive appraisal (α = 0.46 and α = 0.41, respectively). Of the pregnant women, 55.33% and 55.27%, respectively, reported scores of ≥40 on STAI-S and STAI-T, and the respective percentages for the postpartum women were 47.34% and 46.80%. In addition, 14.39% of the pregnant women and 20.74% of the postpartum women scored ≥13 on the EPDS. Higher preparedness stress on PREPS and PREPS-PP was associated with primiparity (P = 0.022 and P = 0.021, respectively) and disrupted perinatal care (P = 0.069 and P = 0.007, respectively). In postpartum women, higher infection stress was associated with chronic disease (P = 0.037), primiparity (P = 0.02) and perceived risk of infection (P = 0.065). Higher score on infection stress was associated with disrupted perinatal care in both groups (P = 0.107 and P = 0.010, respectively).

The Greek versions of PREPS and PREPS-PP are valid tools for the assessment of women at risk of perinatal stress during a health crisis.

As of 2018, there were over 11 million people imprisoned globally. Suicide and self-harm rates have been found to be markedly elevated among imprisoned individuals, however there is much less literature reporting on risk factors for suicide and self-harm following prison release. The immediate post-release period has been found to be a particularly high-risk period for suicide and self-harm. Since many more people are released into the community every year than people kept imprisoned, released prisoners' health is a matter of public health concern. With the societal impact of this topic in mind, this systematic review aims to collate the risk factors for suicide and self-harm upon release from prison.

PubMed, PsycINFO, MEDLINE, and Cochrane were systematically searched using keywords relating to prison release, self-harm and suicide for articles published since 1/1/12. Studies were included if they reported data on risk factors for self-harm or suicide and followed prespecified inclusion criteria. Articles were screened by the author and uncertainty was settled by two independent reviewers. Included studies were evaluated using standardised quality assessment tools. Quantitative data were narratively synthesised due to a high level of heterogeneity in between studies.

248 articles were identified in total. 10 articles were included, reporting data on self-harm and suicide risk factors from 5 countries. Studies ranged from moderate (n = 2) to high quality (n = 8). Risk factors were categorised into the following: demographic characteristics, psychiatric history, conviction type, and imprisonment history. Risk factors which did not fit into any of these categories were categorised into an ”other” group. It was found that there were many non-modifiable factors such as violent convictions, female sex, Indigenous (Torres Strait Islander or Aboriginal) ethnicity, and single relationship status which increase self-harm or suicide risk upon release.

To our knowledge, this is the first systematic review to collate the risk factors for suicide and self-harm following prison release. The results show a complex variety of risk factors. The high mortality rate in this group necessitates the need for strategies to intervene before community re-entry. Study into risk factors post-release may guide identification of at-risk groups to target with proactive, coordinated care pre- and post-release. It is likely this will require a multifactorial approach including health, social and community programmes.

Previous studies suggest that migrants tend to utilise antipsychotics less often than their native-born peers. However, studies examining antipsychotic use among refugees with psychosis are lacking.

To compare the prevalence of antipsychotic drug use during the first 5 years of illness among refugees and Swedish-born individuals with a newly diagnosed non-affective psychotic disorder, and to identify sociodemographic and clinical factors associated with antipsychotic use.

The study population included refugees (n = 1656) and Swedish-born persons (n = 8908) aged 18–35 years during 2007–2018, with incident diagnosis of non-affective psychotic disorder recorded in the Swedish in-patient or specialised out-patient care register. Two-week point prevalence of antipsychotics use was assessed every 6 months in the 5 years following first diagnosis. Factors associated with antipsychotic use (versus non-use) at 1 year after diagnosis were examined with modified Poisson regression.

Refugees were somewhat less likely to use antipsychotics at 1 year after first diagnosis compared with Swedish-born persons (37.1% v. 42.2%, age- and gender-adjusted risk ratio 0.88, 95% CI 0.82–0.95). However, at the 5-year follow-up, refugees and Swedish-born individuals showed similar patterns of antipsychotic use (41.1% v. 40.4%). Among refugees, higher educational level (>12 years), previous antidepressant use and being diagnosed with schizophrenia/schizoaffective disorder at baseline were associated with an increased risk of antipsychotics use, whereas being born in Afghanistan or Iraq (compared with former Yugoslavia) was associated with decreased risk.

Our findings suggest that refugees with non-affective psychotic disorders may need targeted interventions to ensure antipsychotic use during the early phase of illness.

Prenatal selective serotonin reuptake inhibitor (SSRI) antidepressant exposure is associated with increased internalising and anxious behaviours in young children; whether this continues into early adolescence is unknown. Also, it is not well established whether it is the in utero exposure to SSRIs or the underlying maternal mood that contributes more to these associations.

To examine associations between maternal depressive symptoms, prenatal SSRI antidepressant treatment and internalising and anxiety behaviours from childhood into pre-adolescence.

From a prospective longitudinal cohort, measures of maternal depressive symptoms and SSRI use and child outcomes (n = 191 births) were obtained from the second trimester to 12 years. Maternal reports of internalising and anxiety behaviours in children were obtained at 3, 6 and 12 years.

Multilevel mixed-effects models revealed that maternal depressed mood at the third trimester assessment, not prenatal SSRI exposure, was associated with longitudinal patterns of higher levels of internalising and anxiety behaviours across childhood from 3 to 12 years of age. At each age, hierarchical regressions showed that maternal mood at the third trimester, compared with current maternal depression or prenatal SSRI exposure, explained a greater proportion of the variance in internalising and anxiety behaviours.

Even with prenatal SSRI treatment, maternal depressed mood during the third trimester still had an enduring effect as it was associated with increased levels of internalising and anxiety behaviours across childhood and into early adolescence. Importantly, we found no evidence of a ‘main effect’ association between prenatal SSRI exposure and internalising and anxiety behaviours in children.

Substance use disorders are associated with significant physical health comorbidities, necessitating an integrated treatment response. However, service fragmentation can preclude the management of physical health problems during addiction treatment. (Osborne et al, 2022). Northeast England continues to have the highest morbidity /mortality with regards to substance use (ONS, 2022). Therefore, it is essential that staff in addiction health settings innovate to address physical health.

A review of the literature identified little research relating to physical health care in addiction and recovery settings. Our service protocol for blood testing was used to set the audit standards. The blood testing assessed electronic communication and electronic records. Physical health nurses take blood on request and email blood results to a medical/clinician inbox. The total sample was 1128 since pathway inception in March 2022.A sample size of 70 was selected via systematic sampling using n-15th person. Descriptive analyses of data followed by qualitative exploration with the physical health team was completed. The audit was registered locally.

Of the sample size of 70 whose records were reviewed, we noted that blood tests were reviewed by medics (100%) with 98.6% of these reviews being within 6 hours of notification by the physical health team. Action plans were documented for blood results requests and communicated by email to physical health team (100%). 84.3% of the action plans were completed by physical health team on receipt of emails. Non completion of action plans in 15.7% of cases was related to client being hospitalised or disengaging from services (which might include relocation out of area or transfer into the criminal justice system).

Within our service, we have patients who struggle to attend conventional pathways e.g., GP. In view of the previously stated morbidity and mortality it is important that we are able to offer blood testing with timely follow up and action plans when appropriate to these patients.

Our service has good liaison with local services and bespoke partnerships to cater for the homeless amongst other subgroups. We used this audit to also improve processes and patient safety with plans for a re-audit. There was no previous nor national comparison for these data.

The World Psychiatric Association recently emphasised that the protection of human rights in mental healthcare was a ‘central concern’. This paper examines recent literature on human rights and mental healthcare.

To (a) outline how international human rights law distinguishes between the protection and promotion of human rights; and (b) explore the literature on promoting human rights in mental healthcare which avoids what has been termed the ‘Geneva impasse’ between those who argue that compulsory care and treatment can never comply with human rights law and those who argue that they can if certain conditions are met.

The following doctrinal methodology was used: (a) identification and detailed analysis of international human rights conventions and commentaries; (b) identification of key literature on human rights and mental healthcare; and (c) critical analysis of key issues emerging from the literature.

Much of the literature on human rights and mental healthcare focuses on whether restrictions on compulsory care are required to meet the requirements of United Nations Conventions. There is an emerging literature identifying measures to promote the right to the enjoyment of the highest attainable standard of mental health.

There has been a focus on protecting the rights to liberty and equality before the law for mental health patients. The nascent literature on promoting human rights in mental healthcare could mark a way forward beyond the ‘Geneva impasse’ that has dominated public debate in recent years.

Studies have reported elevated rates of dissociative symptoms and comorbid dissociative disorders in functional neurological disorder (FND); however, a comprehensive review is lacking.

To systematically review the severity of dissociative symptoms and prevalence of comorbid dissociative disorders in FND and summarise their biological and clinical associations.

We searched Embase, PsycInfo and MEDLINE up to June 2021, combining terms for FND and dissociation. Studies were eligible if reporting dissociative symptom scores or rates of comorbid dissociative disorder in FND samples. Risk of bias was appraised using modified Newcastle–Ottawa criteria. The findings were synthesised qualitatively and dissociative symptom scores were included in a meta-analysis (PROSPERO CRD42020173263).

Seventy-five studies were eligible (FND n = 3940; control n = 3073), most commonly prospective case–control studies (k = 54). Dissociative disorders were frequently comorbid in FND. Psychoform dissociation was elevated in FND compared with healthy (g = 0.90, 95% CI 0.66–1.14, I2 = 70%) and neurological controls (g = 0.56, 95% CI 0.19–0.92, I2 = 67%). Greater psychoform dissociation was observed in FND samples with seizure symptoms versus healthy controls (g = 0.94, 95% CI 0.65–1.22, I2 = 42%) and FND samples with motor symptoms (g = 0.40, 95% CI −0.18 to 1.00, I2 = 54%). Somatoform dissociation was elevated in FND versus healthy controls (g = 1.80, 95% CI 1.25–2.34, I2 = 75%). Dissociation in FND was associated with more severe functional symptoms, worse quality of life and brain alterations.

Our findings highlight the potential clinical utility of assessing patients with FND for dissociative symptomatology. However, fewer studies investigated FND samples with motor symptoms and heterogeneity between studies and risk of bias were high. Rigorous investigation of the prevalence, features and mechanistic relevance of dissociation in FND is needed.

Burnout is a consequence of chronic occupational stress. Specific work-related factors may contribute to burnout experienced by those working in mental health services (MHS), many of which have increased since the COVID-19 pandemic.

To examine personal, work- and patient-related burnout among MHS staff in Ireland during the COVID-19 pandemic, and explore the impact of work-related conditions on burnout.

We conducted a cross-sectional survey of three MHS across Ireland utilising a study-specific questionnaire, the Copenhagen Burnout Inventory and the Effort–Reward Imbalance scale.

Of 396 participants, 270 (70.6%) were female. Moderate and high personal burnout was experienced by 244 (64.1%) participants; work-related burnout by 231 (58.5%) participants and patient-related burnout by 83 (21.5%) participants. Risk factors for both personal and work-related burnout were female gender, urban service, time spent outside main responsibilities, overcommitment, high score on the Effort–Reward Imbalance scale and intention to change job. Being younger, with high workload and deterioration of personal mental health during the pandemic was associated with higher personal burnout, whereas a lack of opportunity to talk about work-related stress contributed to work-related burnout. Fewer factors were associated with patient-related burnout, namely overcommitment, working in urban services and poorer physical and mental health during the COVID-19 pandemic.

High levels of personal and work-related burnout were found among mental health workers. The weak association with COVID-19-related factors suggest levels of burnout predated the pandemic. This has implications for MHS given the recognised additional work burden created by COVID-19.

Few population-based studies have compared the mental health of gender minority and cisgender adolescents.

To compare reports of psychological distress, behavioural and emotional difficulties, self-harm and suicide attempts between gender minority and cisgender adolescents.

Data came from the Millennium Cohort Study (n = 10 247), a large nationally representative birth cohort in the UK. At a 17-year follow-up, we assessed gender identity, psychological distress (Kessler K6 scale), behavioural and emotional difficulties (parent and child reports on the Strengths and Difficulties Questionnaire), self-harm in the previous year, suicide attempts, substance use, and victimisation including harassment and physical and sexual assaults. Multivariable modified Poisson and linear regression models were used. Attenuation after the inclusion of victimisation and substance use was used to explore mediation.

Of the 10 247 participants, 113 (1.1%) reported that they were a gender minority. Gender minority participants reported more psychological distress (coefficient 5.81, 95% CI 4.87–6.74), behavioural and emotional difficulties (child report: coefficient 5.60; 95% CI 4.54–6.67; parent/carer report: coefficient 2.60; 95% CI 1.47–3.73), self-harm including cutting or stabbing (relative risk (RR) 4.38; 95% CI 3.55–5.40), burning (RR 3.81; 95% CI 2.49–5.82), taking an overdose (RR 5.25; 95% CI 3.35–8.23) and suicide attempts (RR 3.42; 95% CI 2.45–4.78) than cisgender youth. These associations were partially explained by differences in exposure to victimisation.

Gender minority adolescents experience a disproportionate burden of mental health problems. Policies are needed to reduce victimisation and services should be adapted to better support the mental health of gender minority adolescents.

Studies about brain structure in bipolar disorder have reported conflicting findings. These findings may be explained by the high degree of heterogeneity within bipolar disorder, especially if structural differences are mapped to single brain regions rather than networks.

We aim to complete a systematic review and meta-analysis to identify brain networks underlying structural abnormalities observed on T1-weighted magnetic resonance imaging scans in bipolar disorder across the lifespan. We also aim to explore how these brain networks are affected by sociodemographic and clinical heterogeneity in bipolar disorder.

We will include case–control studies that focus on whole-brain analyses of structural differences between participants of any age with a standardised diagnosis of bipolar disorder and controls. The electronic databases Medline, PsycINFO and Web of Science will be searched. We will complete an activation likelihood estimation analysis and a novel coordinate-based network mapping approach to identify specific brain regions and brain circuits affected in bipolar disorder or relevant subgroups. Meta-regressions will examine the effect of sociodemographic and clinical variables on identified brain circuits.

Findings from this systematic review and meta-analysis will enhance understanding of the pathophysiology of bipolar disorder. The results will identify brain circuitry implicated in bipolar disorder, and how they may relate to relevant sociodemographic and clinical variables across the lifespan.

Clinicians working in mental health in-patient settings may have to use nasogastric tube feeding under physical restraint to reverse the life-threatening consequences of malnutrition when this is driven by a psychiatric condition such as a restrictive eating disorder.

To understand the decision-making process when nasogastric tube feeding under restraint is initiated in mental health in-patient settings.

People with lived experience of nasogastric tube feeding under restraint and parents/carers were recruited via the website of the UK's eating disorder charity BEAT. Eating disorder clinicians were recruited via an online post by the British Eating Disorders Society. Semi-structured interviews were administered to all participants.

Themes overlapped between the participant groups and were integrated in the final analysis. Two main themes were generated: first, ‘quick decisions’, with the subthemes of ‘medical risk’, ‘impact of not eating’ and ‘limited discussions’; second, ‘slow decisions’, with subthemes of ‘threats’, ‘discussions with patient’, ‘not giving up’ and ‘advanced directives’. Benefits and harms of both quick and slow decisions were identified.

This research offers a new perspective regarding how clinical teams can make best practice decisions regarding initiating nasogastric feeding under restraint. In-patient mental health teams facilitating this clinical intervention should consider discussing it with the patient at the beginning of their admission in anticipation of the need for emergency intervention and in full collaboration with the multidisciplinary team.

Prior self-harm represents the most significant risk factor for future self-harm or suicide.

To evaluate the cost-effectiveness of a theoretical brief aftercare intervention (involving brief follow-up contact, care coordination and safety planning), following a hospital-treated self-harm episode, for reducing repeated self-harm within the Australian context.

We employed economic modelling techniques to undertake: (a) a return-on-investment analysis, which compared the cost-savings generated by the intervention with the overall cost of implementing the intervention; and (b) a cost–utility analysis, which compared the net costs of the intervention with health outcomes measured in quality-adjusted life years (QALYs). We considered cost offsets associated with hospital admission for self-harm and the cost of suicide over a period of 10 years in the base case analysis. Uncertainty and one-way sensitivity analyses were also conducted.

The brief aftercare intervention resulted in net cost-savings of AUD$7.5 M (95% uncertainty interval: −56.2 M to 15.1 M) and was associated with a gain of 222 (95% uncertainty interval: 45 to 563) QALYs over a 10-year period. The estimated return-on-investment ratio for the intervention's modelled cost in relation to cost-savings was 1.58 (95% uncertainty interval: −0.17 to 5.33). Eighty-seven per cent of uncertainty iterations showed that the intervention could be considered cost-effective, either through cost-savings or with an acceptable cost-effectiveness ratio of 50 000 per QALY gained. The results remained robust across sensitivity analyses.

A theoretical brief aftercare intervention is highly likely to be cost-effective for preventing suicide and self-harm among individuals with a history of self-harm.

The aim of the study was to investigate the potential association between gambling disorder and symptoms of sleep problems including insomnia and hypersomnolence. Gambling disorder is a behavioural addiction featuring persistent, recurrent gambling resulting in distress and impairment of function. Lifetime prevalence of gambling disorder is estimated at 0.6–0.9%, though high quality data in the UK are lacking. Psychiatric comorbidity is common; as are physical health problems such as hypertension. The association between sleep problems and other addictions such as alcohol misuse disorder, smoking and substance misuse has been established; however, research into gambling disorder and sleep problems is limited. It was hypothesised that, compared to controls, individuals with gambling disorder would have significantly greater disturbance of sleep, as indicated by increased scores in: 1) specific sleep items on the Hamilton Anxiety Rating Scale (HAMA) and Hamilton Rating Scale for Depression (HAMD), 2) total score on the HAMA and HAMD and 3) the Epworth Sleepiness Scale (ESS).

A secondary analysis of a subset of previously published data by Grant and Chamberlain (2018) on gambling and impulsivity. A total of 152 non-treatment seeking adults, aged 18–29 years, who had gambled at least five times in the past year were recruited. Individuals were stratified into three groups: controls, those at risk of gambling disorder, and those with gambling disorder, as per DSM-5 criteria. One-way ANOVAs with post-hoc tests were conducted. These were used to show whether the three groups differed significantly in their scores in the sleep items and total scores of the HAMA and HAMD, and the ESS.

The HAMD scale demonstrated a significant increase in all patterns of insomnia for members of the disorder group, when compared to controls. The increase was particularly marked for middle and late insomnia. The HAMA item score demonstrated significantly worse sleep quality in the disorder group, compared to at risk and control groups. Total scores on the HAMA and HAMD scales were also significantly higher in the disorder group, reaching the thresholds for clinical significance for anxiety and depression. ESS scores were not significantly different between groups.

Global disruptions in sleep, as well late- and middle-insomnia, were found to be significantly higher in gambling disorder than controls. Symptoms of anxiety and depression were also significantly higher in the gambling disorder group. Further research could have implications for the identification and treatment of sleep disorders and psychiatric comorbidities in gambling disorder.

Public and patient expectations of treatment influence health behaviours and decision-making.

We aimed to understand how the media has portrayed the therapeutic use of ketamine in psychiatry.

We systematically searched electronic databases for print and online news articles about ketamine for psychiatric disorders. The top ten UK, USA, Canadian and Australian newspapers by circulation and any trade and consumer magazines indexed in the databases were searched from 2015 to 2020. Article content was quantitatively coded with a framework encompassing treatment indication, descriptions of prior use, references to research, benefits and harms, treatment access and process, patient and professional testimony, tone and factual basis.

We found 119 articles, peaking in March 2019 when the United States Food and Drug Administration approved esketamine. Ketamine treatment was portrayed in an extremely positive light (n = 82, 68.9%), with significant contributions of positive testimony from key opinion leaders (e.g. clinicians). Positive research results and ketamine's rapid antidepressant effect (n = 87, 73.1%) were frequently emphasised, with little reference to longer-term safety and efficacy. Side-effects were frequently reported (n = 96, 80.7%), predominantly ketamine's acute psychotomimetic effects and the potential for addiction and misuse, and rarely cardiovascular and bladder effects. Not infrequently, key opinion leaders were quoted as being overly optimistic compared with the existing evidence base.

Information pertinent to patient help-seeking and treatment expectations is being communicated through the media and supported by key opinion leaders, although some quotes go well beyond the evidence base. Clinicians should be aware of this and may need to address their patients’ beliefs directly.

Evidence from pandemic and pre-pandemic studies conducted globally indicates that people with disabilities (PWDs) have a higher risk for suicidality. However, none of these studies has assessed suicidality among PWDs in Bangladesh.

The purpose of this study was to determine the prevalence of and factors associated with suicidal ideation among PWDs during the COVID-19 pandemic in Bangladesh.

Using a snowball sampling technique, a cross-sectional survey was conducted from February to April 2021 among PWDs from six districts in the northern region of Bangladesh. Information related to sociodemographic factors, clinical characteristics, behavioural factors and suicidal ideation was collected. Chi-squared test and logistic regression were used to describe the data and explain the relationship of factors associated with suicidal ideation.

The prevalence of COVID-19-related past-year suicidal ideation was 23.9%. The factors associated with suicidal ideation included: age above 35 years, being female, acquiring a disability later in life, lack of sleep and current substance use. In addition, higher education appeared to be a protective factor against suicidal ideation.

This study highlighted that PWDs had an increased risk of suicide; that is, one-fourth of them had past-year suicidal ideation. This may have been because of COVID-19-related restrictions and stressors. Thus, the government and policy makers need to pay more attention to developing effective suicide assessment, treatment and management strategies, especially for at-risk groups, to minimise the impact of the COVID-19 outbreak.
