The prospective association between sleep duration and the development of late-life depressive symptomology is unclear.

To investigate sleep duration from midlife to late life in relation to risk of depressive symptoms in late life.

A total of 14 361 participants from the Singapore Chinese Health Study were included in the present study. Daily sleep duration was self-reported at baseline (mean age of 52.4 years; 1993–98), follow-up 2 (mean age of 65.2 years; 2006–10) and follow-up 3 (mean age of 72.5 years; 2014–16) interviews. Depressive symptoms were evaluated using the Geriatric Depression Scale at follow-up 3 interviews. Modified Poisson regression models were performed to estimate relative risks and 95% confidence intervals of late-life depressive symptoms in relation to sleep duration at baseline and the two follow-up interviews.

Compared with sleeping 7 h per day, a short sleep duration of ≤5 h per day at baseline (i.e. midlife) was related to a higher risk of depressive symptoms (relative risk 1.10, 95% CI 1.06–1.15), and this risk was not affected by subsequent prolongation of sleep. Conversely, a long sleep duration of ≥9 h per day at baseline was not related to risk of depressive symptoms. At follow-up 3 (i.e. late life), both short sleep (relative risk 1.20, 95% CI 1.16–1.25) and long sleep (relative risk 1.12, 95% CI 1.07–1.18) duration were cross-sectionally associated with depressive symptoms.

Short sleep duration in midlife, regardless of subsequent prolongation, is associated with an increased risk of depression in late life. Contrariwise, both short and long sleep duration in late life co-occur with depressive symptoms.

Domestic abuse is a significant risk factor for self-harm and suicide. A large proportion of people presenting to healthcare services following self-harm have experienced domestic abuse. In the UK, routine enquiry for domestic abuse is recommended for people who present having self-harmed, but evidence indicates that this is not happening.

An exploratory qualitative study to explore liaison psychiatry staff experiences of asking about domestic abuse, including the barriers and challenges to asking.

Semi-structured qualitative interviews with active adult liaison psychiatry staff in the UK. Recruitment was via online platforms and professional networks. A reflexive thematic analysis of the narratives was carried out.

Fifteen participants were interviewed across a variety of disciplines (ten nurses, four doctors, one social worker). The generated themes include the following: asking about domestic abuse – the tension between knowing and doing; ‘delving deeper’ and the fear of making things worse; the entanglement of shame, blame and despondency; domestic abuse was different from other clinical problems (mental illness/substance misuse); and biases, myths and misassumptions guiding practice. Participants indicated the need for better training and education, and clear protocols for eliciting and acting on disclosures.

There is a clear need to improve the support offered to victim-survivors of domestic abuse who self-harm and present to healthcare services. National implementation of education and training to better equip liaison psychiatry teams with the skills and knowledge to sensitively support victim-survivors of domestic abuse is required.

On 15 March 2019, a white supremacist gunman sequentially attacked two mosques in Christchurch, New Zealand, killing 51 people aged from 3 to 77 years and bullet-injuring 40 more. Approximately 250 people survived the atrocity, and many more family and community members have been directly or indirectly affected.

To develop an understanding of the personal experiences of some of those affected, including effects on daily life and well-being, in the 18–30 months following the attacks.

Qualitative thematic analysis of semi-structured interviews with 21 men and women from September 2020 to August 2021 was performed. Participants were drawn from a larger quantitative study and included injured, bereaved, witnesses, family members and those from the wider Muslim community in Christchurch.

Four superordinate themes were identified: being overwhelmed in the midst of chaos; experiencing silent and enduring impact; living similarly, but differently; and gaining meaning and growth. These themes captured ongoing distress inclusive of physical symptoms, family and community relationship dynamics and connectedness, secondary stressors, and diversity in coping and growth. For most, the centrality of Islam as a faith tradition was woven throughout.

Consistent with previous literature, post-trauma reactions were pervasive and varied. This appeared to be compounded by secondary stressors in this cohort, such as sociopolitical circumstances, demographic diversity, the COVID-19 pandemic and justice processes. Findings also revealed a strong spiritual thread in the experiences of this minority faith community, shedding light on a complex interaction between recovery and post-traumatic growth.

The Republic of Cyprus has recorded the greatest increase in suicide mortality among Eastern Mediterranean countries, with an average annual increase of 5.1% in 2000–2019.

To investigate trends in suicide mortality rates between 2004 and 2020 in the Republic of Cyprus, with a focus on age, gender and suicide methods.

Suicide deaths (ICD-10 taxonomy, including ‘undetermined’ code) and population denominators were obtained from the National Mortality Registry and Statistical Office, respectively. Directly standardised (European Standard) mortality rates were calculated for four gender and age groups. Annual change was estimated using Poisson regression models with interaction terms to assess differential trends over different time periods.

There were 560 suicide deaths; these were four times more frequent in men, and approximately 80% were classified as ‘violent’ for both genders. The male suicide rate doubled from 4–5 to 9–10 per 100 000, mostly before 2012, representing a 9% annual change (rate ratio = 1.09, 95% CI 1.03, 1.15; P = 0.002). From 2013, the trend reversed (effect modification P < 0.001) with a 4% annual decrease (95% CI −9%, 1%). Declines were not uniform across all age groups; rates in males aged 45–64 years continued to rise, surpassing the previously high rate in males aged 25–44 years. Rates in females declined from 4–5 per 100 000 to 2–3 over the study period. Overall, the male-to-female suicide rate ratio was 5.33 (95% CI 3.46, 8.19) in 2017–2020, compared with 2.73 (1.88, 3.95) in 2004–2008.

Although suicide rates remain relatively low, the gender differential has widened in the Republic of Cyprus. Further analysis of trends in relation to unemployment and other socioeconomic indicators is warranted.

Although there is now substantial evidence on the acute impacts of the COVID-19 pandemic on anxiety disorders, the long-term population impact of the pandemic remains largely unexplored.

To quantify a possible longitudinal population-level impact of the pandemic by projecting the prevalence of anxiety disorders through 2030 among men and women aged up to 95 years in Germany under scenarios with varying impacts of the pandemic on the incidence of anxiety disorders.

We used a three-state illness–death model and data from the Global Burden of Disease Study to model historical trends of the prevalence and incidence of anxiety disorders. The German population projections determined the initial values for projections. The COVID-19 incidence rate data informed an additional incidence model, which was parameterised with a wash-in period, delay, wash-out period, incidence increase level and decay constant.

When no additional increase in the incidence during the pandemic waves during 2020–2022 was assumed, it was estimated that 3.86 million women (9.96%) and 2.13 million men (5.40%) would have anxiety disorders in 2030. When increases in incidence following pandemic waves were assumed, the most extreme scenario projected 5.67 million (14.02%) women and 3.30 million (8.14%) men with the mental disorder in 2030.

Any increased incidence during the pandemic resulted in elevated prevalence over the projection period. Projection of anxiety disorder prevalence based on the illness–death model enables simulations with varying assumptions and provides insight for public health planning. These findings should be refined as trend data accumulate and become available.

Research on schizophrenia and life expectancy has mainly focused on premature mortality.

This study investigates factors associated with longevity in patients with schizophrenia receiving long-term care and identifies shared traits among these individuals.

A retrospective cross-sectional study analysing the clinical records of 138 patients with schizophrenia who died between 2015 and 2017 in a psychiatric long-term care facility was conducted. Longevity was defined by life tables drawn from the national health database. Variables were compared between longevity and control groups to determine predictors of longer lifespans. Cluster analysis was employed to identify shared traits among individuals with longevity. Causes of death by age were compared.

In the long-term care setting, of the 138 participants, 45 were in the longevity group. This group had more males, lower antipsychotic doses, but more mobility issues. Significant predictors of longevity included older age at onset, longer length of stay, lower activities of daily living scores and a hypertension diagnosis. Cluster analysis revealed two patterns, suggesting that poorer health indicators did not necessarily lead to shorter lives. Fatalities caused by pneumonia were associated with a higher age, compared to those from cancer and choking.

Addressing modifiable risk factors enhances life expectancy in patients with schizophrenia, especially for males, while the age at onset may play a significant role. An integrated long-term care model with close monitoring and timely provision of mental and general healthcare may help extend lifespans. Further research is needed to balance long-term residential care and community-based care for elderly patients with schizophrenia.

People with severe mental illness (SMI) have worse physical health than the general population. There is evidence that support from volunteers can help the mental health of people with SMI, but little evidence regarding the support they can give for physical health.

To evaluate the feasibility of an intervention where volunteer ‘Health Champions’ support people with SMI in managing their physical health.

A feasibility hybrid randomised controlled trial conducted in mental health teams with people with SMI. Volunteers delivered the Health Champions intervention. We collected data on the feasibility of delivering the intervention, and clinical and cost-effectiveness. Participants were randomised by a statistician independent of the research team, to either having a Health Champion or treatment as usual. Blinding was not done.

We recruited 48 participants: 27 to the intervention group and 21 to the control group. Data were analysed for 34 participants. No changes were found in clinical effectiveness for either group. Implementation outcomes measures showed high acceptability, feasibility and appropriateness, but with low response rates. No adverse events were identified in either group. Interviews with participants found they identified changes they had made to their physical health. The cost of implementing the intervention was £312 per participant.

The Health Champion intervention was feasible to implement, but the implementation of the study measures was problematic. Participants found the intervention acceptable, feasible and appropriate, and it led them to make changes in their physical health. A larger trial is recommended, with tailored implementation outcome measures.

Rates of acute mental health presentations in youth were increasing pre-pandemic internationally. Longitudinal studies following COVID-19 attest to ongoing deterioration in youth mental health, recognising adverse unintended consequences following public health restrictions.

To examine whether the initial post-COVID-19 increase in mental health presentations persisted following the reclassification of COVID-19 to endemic status, accompanied by the removal of most restrictions.

All referrals to paediatric liaison psychiatry (PLP) between January 2018 and December 2022 in a Dublin tertiary children's hospital were included in the study. An interrupted time series analysis with autoregressive integrated moving average models was conducted, examining referrals with respect to different phases of COVID-19 and application of public health restrictions.

Some 1385 referrals to PLP were received over the 5-year study. There was a significant decrease in PLP referrals immediately post-COVID-19, followed by a significant and sustained increase as the pandemic progressed and moved to endemic status. Public health restriction phases had a unique effect on those presenting with suicidal ideation, with a significant increase in the number of referrals. There was no effect of restrictions on other clinical profiles.

Increased referrals for youth with mental health difficulties, reported during the COVID-19 pandemic, persisted into the early endemic stage, after COVID-19 public health restrictions ceased. Specific impacts of restrictions on suicidal ideation referrals require further study. Investment in child and adolescent mental health services remains a priority, and future pandemic response strategies need to examine unintended consequences of any enforced public health measure.

Although clozapine is the most effective antipsychotic for people with treatment-resistant schizophrenia (TRS), only 40% of people with TRS respond, and there is limited evidence for augmentation agents. Cannabidiol (CBD) reduces positive symptoms in individuals with schizophrenia, but no trials have specifically examined its efficacy in those with clozapine-resistant schizophrenia.

To examine the clinical efficacy of CBD augmentation in people with clozapine-resistant schizophrenia.

This is a 12-week randomised, placebo-controlled, double-blind, parallel-group trial (registration number: ACTRN12622001112752). We will recruit 88 individuals with clozapine-resistant schizophrenia, randomised (1:1) to 1000 mg daily CBD versus placebo. Eligible individuals will be aged between 18 and 64 years, fulfil DSM-IV criteria for schizophrenia or schizoaffective disorder, have a total PANSS (Positive and Negative Syndrome Scale) score ≥60, have received oral clozapine for at least 18 weeks and have a clozapine level of >350 ng/mL. Interim analyses will be conducted at 25, 50 and 75% recruitment; these will also provide an opportunity to reallocate participants dependent on conditional power. The primary endpoint will be the difference in PANSS positive scores at the end of week 12. Secondary endpoints include depression, anxiety, sleep, quality of life, alcohol consumption, change in weight and metabolic syndrome components, and neurocognitive measures, as well as safety and tolerability.

Novel treatments for clozapine-resistant schizophrenia are urgently needed. If found to be effective, CBD may have a role as a novel and safe adjunct to clozapine.

Having social support improves one's health outcomes and self-esteem, and buffers the negative impact of stressors. Previous studies have explored the association between social support and brain activity, but evidence from task-dependent functional connectivity is still limited.

We aimed to explore how gradually decreasing levels of social support influence task-dependent functional connectivity across several major neural networks.

We designed a social support task and recruited 72 young adults from real-life social groups. Of the four members in each group, one healthy participant (18 participants in total) completed the functional magnetic resonance imaging (fMRI) scan. The fMRI task included three phases with varying levels of social support: high-support phase, fair phase and low-support phase. Functional connectivity changes according to three phases were examined by generalised psychophysiological interaction analysis.

The results of the analysis demonstrated that participants losing expected support showed increased connectivity among salience network, default mood network and frontoparietal network nodes during the fair phase compared with the high-support phase. During the low-support phase, participants showed increased connectivity among only salience network nodes compared with the high-support phase.

The results indicate that the loss of support was perceived as a threat signal and induced widespread increased functional connectivity within brain networks. The observation of significant functional connectivity changes between fair and high-support phases suggests that even a small loss of social support from close ones leads to major changes in brain function.

Data on associations between inflammation and depressive symptoms largely originate from high income population settings, despite the greatest disease burden in major depressive disorder being attributed to populations in lower-middle income countries (LMICs).

We assessed the prevalence of low-grade inflammation in adults with treatment-resistant depression (TRD) in Pakistan, an LMIC, and investigated associations between peripheral C-reactive protein (CRP) levels and depressive symptoms.

This is a secondary analysis of two randomised controlled trials investigating adjunctive immunomodulatory agents (minocycline and simvastatin) for Pakistani adults with TRD (n = 191). Logistic regression models were built to assess the relationship between pre-treatment CRP (≥ or <3 mg/L) and individual depressive symptoms measured using the Hamilton Depression Rating Scale. Descriptive statistics and regression were used to assess treatment response for inflammation-associated symptoms.

High plasma CRP (≥3 mg/L) was detected in 87% (n = 146) of participants. Early night insomnia (odds ratio 2.33, 95% CI 1.16–5.25), early morning waking (odds ratio 2.65, 95% CI 1.29–6.38) and psychic anxiety (odds ratio 3.79, 95% CI 1.39–21.7) were positively associated, while gastrointestinal (odds ratio 0.38, 95% CI 0.14–0.86) and general somatic symptoms (odds ratio 0.34, 95% CI 0.14–0.74) were negatively associated with inflammation. Minocycline, but not simvastatin, improved symptoms positively associated with inflammation.

The prevalence of inflammation in this LMIC sample with TRD was higher than that reported in high income countries. Insomnia and anxiety symptoms may represent possible targets for personalised treatment with immunomodulatory agents in people with elevated CRP. These findings require replication in independent clinical samples.

Medications with anticholinergic properties are associated with a range of adverse effects that tend to be worse in older people.

To investigate medication regimens with high anticholinergic burden, prescribed for older adults under the care of mental health services.

Clinical audit of prescribing practice, using a standardised data collection tool.

Fifty-seven trusts/healthcare organisations submitted data on medicines prescribed for 7915 patients: two-thirds (66%) were prescribed medication with anticholinergic properties, while just under a quarter (23%) had a medication regimen with high anticholinergic burden (total score ≥3 on the anticholinergic effect on cognition (AEC) scale). Some 16% of patients with a diagnosis of dementia or mild cognitive impairment were prescribed medication regimens with a high anticholinergic burden, compared with 35% of those without such diagnoses. A high anticholinergic burden was mostly because of combinations of commonly prescribed psychotropic medications, principally antidepressant and antipsychotic medications with individual AEC scores of 1 or 2.

Adults under the care of older people's mental health services are commonly prescribed multiple medications for psychiatric and physical disorders; these medication regimens can have a high anticholinergic burden, often an inadvertent consequence of the co-prescription of medications with modest anticholinergic activity. Prescribers for older adults should assess the anticholinergic burden of medication regimens, assiduously check for adverse anticholinergic effects and consider alternative medications with less anticholinergic effect where indicated. The use of a scale, such as the AEC, which identifies the level of central anticholinergic activity of relevant medications, can be a helpful clinical guide.

Literature emphasises the importance of identifying and intervening in the adoption of unhealthy lifestyle behaviours (ULBs) during adolescence at an early stage, to mitigate their long-term detrimental effects. Among the possible associated factors contributing to ULBs, attention-deficit hyperactivity disorder (ADHD) has been shown to play an important role. However, little is known about ADHD subclinical manifestations.

The present study aimed to bridge the gap in the literature and shed light on the relationship between subclinical ADHD and early adoption of ULBs during adolescence. Through a clinimetric approach, prevalence of ULBs, severity of ADHD symptoms and psychosocial factors (i.e. allostatic overload, abnormal illness behaviour, quality of life, psychological well-being) were investigated among adolescents. The associations between different degrees of ADHD, ULBs and psychosocial factors were also explored.

This multicentre cross-sectional study involved 440 adolescents (54.5% females; mean age 14.21 years) from six upper secondary schools. Participants completed self-report questionnaires on sociodemographic characteristics, ULBs, ADHD symptoms and psychosocial factors.

The most common ULBs were energy drinks/alcohol consumption and problematic smartphone use. Of the sample, 22% showed subclinical ADHD and 20.2% showed clinical ADHD. The subclinical ADHD group showed several ULBs (i.e. altered mindful eating, impaired quality of sleep, problematic technology use) and psychosocial factors, akin to those of ADHD group and different from peers without ADHD symptoms.

Since subclinical ADHD manifestation is associated with ULBs, similarly to clinical ADHD, identifying subthreshold symptoms during adolescence is crucial, as it could improve health-related outcomes in adulthood across different domains.

The cardiorespiratory effect in mental illnesses has recently received much attention. However, the cardiovascular and pulmonary effects of mood disorders have not been clearly demonstrated.

This study aims to compare individuals with mood disorders and healthy people in terms of exercise capacity, functionality, respiratory muscle strength, pulmonary function, dyspnoea and physical activity level.

This cross-sectional study involved 30 patients with mood disorders and 35 age- and gender-matched healthy individuals. Exercise capacity (6-Minute Walk Test (6MWT), 3-Minute Step Test (3MST)), functionality (vertical jump test, functional reach test), respiratory parameters (respiratory muscle strength, pulmonary function test), dyspnoea (Modified Medical Research Council Dyspnoea Scale) and physical activity level (Short-Form International Physical Activity Questionnaire (IPAQ)) were evaluated.

6MWT results (P < 0.001) and functional test scores (vertical jump test, P = 0.006; functional reach test, P < 0.001) were significantly lower, and heart rate recovery after 3MST (P < 0.001) was higher in mood disorder patients. Although patients' respiratory parameters were lower than healthy individuals, only measured and predicted respiratory muscle strength (P < 0.001), peak expiratory flow rate litres (P < 0.001), forced vital capacity predicted (P = 0.010) and forced expiratory volume in 1 s predicted (P = 0.002) values were statistically significantly different. Dyspnoea with activities was higher in patients (P < 0.001). Patients spent more time sitting (IPAQ, P < 0.001), but overall physical activity levels were similar between the two groups (P > 0.05).

Patients with mood disorders had decreased exercise capacity and pulmonary function, lower functionality scores and respiratory muscle strength, and increased dyspnoea. Exercise-based rehabilitation protocols are recommended for the management of risk factors affecting the mood disorder patients' cardiorespiratory status.

Inflammation is increasingly recognised as a fundamental component of the pathophysiology of major depressive disorder (MDD), with a variety of inflammatory biomarkers playing pivotal roles. These markers are closely linked to both the severity of symptoms and the responsiveness to treatments in MDD.

This scoping review aims to explore the scientific literature investigating the complex relationships between inflammatory biomarkers and depression, by identifying new studies and critical issues in current research.

Following the PRISMA Extension for Scoping Reviews guidelines, we systematically searched databases including PubMed, Scopus, PsycINFO, Open Grey and Cochrane Library. Our search focused on articles published from 1 January 2020 to 1 May 2024. We included studies evaluating inflammatory biomarkers in adult patients with MDD, utilising observational and randomised controlled trial designs, and review studies.

Our analysis examined 44 studies on the complex interplay between inflammation and its multiple effects on MDD. Significant associations between specific inflammatory biomarkers and depression severity were found, requiring cautious interpretation. We also highlight several methodological limitations in the current studies, which warrant caution in directly applying these findings to clinical practice. However, identified methodologies show potential for using these biomarkers as diagnostic tools or therapeutic targets, including anti-inflammatory interventions.

The findings emphasise the need for sophisticated, integrative research to understand inflammation's role in MDD. Future studies should identify specific biomarker panels for diagnosing depression and bridging peripheral biomarker measurements with central neuroinflammatory processes, leading to better diagnostic and treatment strategies.

Patients with schizophrenia die decades earlier than the general population. Among the factors involved in this mortality gap, evidence suggests a telomere length shortening in this clinical population, which is associated with premature ageing. Recent studies support the use of strength-based training exercise programmes to maintain, or even elongate, telomere length in healthy elderly populations. However, studies aiming at modifying telomere length in severe mental illnesses, such as schizophrenia, are still very scarce.

To investigate the effect of a strength-based physical exercise programme on the telomere length of individuals with schizophrenia.

We propose a pragmatic, randomised controlled trial including 40 patients aged ≥18 years, with a stable diagnosis of schizophrenia, attending the Complejo de Rehabilitación Psicosocial (CRPS, Psychosocial Rehabilitation Centre) in Salamanca, Spain. These patients will be randomly assigned (1:1) to either receive the usual treatment and rehabilitation programmes offered by CRPS (treatment-as-usual group) or these plus twice weekly sessions of an evidence-based, strength-based training exercise programme for 12 weeks (intervention group). The primary outcome will be effect on telomere length. Secondary outcomes will include impact on cognitive function, frailty and quality of life.

We expect to show the importance of implementing strength-based physical exercise programmes for patients with schizophrenia. We could find that such programmes induce biological and genetic changes that may lengthen life expectancy and decrease physical fragility.

We anticipate that our trial findings could contribute to parity of esteem for mental health, reducing premature ageing in patients with severe mental illnesses, such as schizophrenia.

Psychoeducational interventions are a critical aspect of supporting adults with attention-deficit hyperactivity disorder (ADHD). The Understanding and Managing Adult ADHD Programme (UMAAP) is a six-session, group-based webinar intervention that incorporates psychoeducation with acceptance and commitment therapy. UMAAP relies on self-referrals and is facilitated by a charity, to promote accessibility.

The present study aimed to evaluate the feasibility of UMAAP and explore preliminary effectiveness.

Adults with formally diagnosed or self-identified ADHD (n = 257) participated in an uncontrolled pre–post design. Feasibility was indicated by attendance, confidence in completing the home practice and satisfaction. Quality of life, psychological flexibility, self-acceptance and knowledge of ADHD were assessed at baseline, 1 week post-intervention and 3 months later, to explore preliminary effectiveness.

Feasibility was demonstrated by the high attendance ratings and satisfaction with the intervention, although there was only moderate confidence in the ability to complete the home practices. Quality of life (mean increase 9.69, 95% CI 7.57–11.80), self-acceptance (mean increase 0.19, 95% CI 0.10–0.28) and knowledge of ADHD (mean increase 1.55, 95% CI 1.23–1.82) were significantly improved post-intervention. The effects were maintained at the 3-month follow-up. Psychological flexibility did not significantly change immediately post-intervention, but increased significantly at the 3-month follow-up (mean increase 0.42, 95% CI 0.26–0.58).

Overall, UMAAP is a feasible intervention for adults with ADHD. Findings highlighted the feasibility of delivering psychological interventions online in group settings, to increase access to support for adults with ADHD.

People with psychosis experience worse cardiometabolic health than the same-aged general population. In New Zealand, Indigenous Māori experiencing psychosis have greater risk of cardiometabolic and other physical health problems.

To identify a cohort of adults accessing secondary mental health and addiction services in New Zealand, with a previous psychosis diagnosis as of 1 January 2018, and compare odds of hospital admission outcomes, mortality and receipt of cardiometabolic blood screening between Māori and non-Māori in the following 2 years.

Crude and adjusted logistic regression models compared odds of hospital admission outcomes, mortality and receipt of cardiometabolic blood screening (lipids and haemoglobin A1c) between Māori and non-Māori, occurring between 1 January 2018 and 31 December 2019.

A cohort (N = 21 214) of Māori (n = 7274) and non-Māori (n = 13 940) was identified. Māori had higher adjusted risk of mortality (odds ratio 1.26, 95% CI 1.03–1.54), and hospital admission with diabetes (odds ratio 1.64, 95% CI 1.43–1.87), cardiovascular disease (odds ratio 1.54, 95% CI 1.25–1.88) and any physical health condition (odds ratio 1.07, 95% CI 1.00–1.15) than non-Māori. Around a third of people did not receive recommended cardiometabolic blood screening, with no difference between Māori and non-Māori after covariate adjustment.

Māori experiencing psychosis are more likely to die and be admitted to hospital with cardiovascular disease or diabetes than non-Māori. Because of the higher cardiometabolic risk borne by Māori, it is suggested that cardiometabolic screening shortfalls will lead to worsening physical health inequities for Māori experiencing psychosis.

The World Health Organization and the Global Burden of Disease study estimate that almost 800 000 people die from suicide yearly. The role of non-traditional risk factors such as climate and high-altitude exposure are poorly understood.

This study aims to determine a potential relationship between altitude exposure and suicide rates among 221 cantons located at different altitudes ranging from 0 to 4300 m.

We conducted an 11-year, country-wide, population-based analysis on age- and gender-standardised suicide rates in Ecuador, based on the official data from the National Institute of Statistics, using all available self-harm death codes (ICD-10 codes X60–X84).

A total of 11 280 cases of suicide were reported during 2011–2021. Suicide rates were higher among men (11.48/100 000). In terms of elevation, suicide rates were significantly higher among people from high-altitude cantons (3.7/100 000) versus those from low-altitude cantons. When applying the International Society Mountain Medicine categorisation, suicide rates were significantly higher at moderate- (4.3/100 000), high- (3.6/100 000) and very-high-altitude cantons (4.4/100 000) when compared with low-altitude locations (2.5/100 000).

Ecuador is one of the few countries that has a vast range of cantons located at different altitudes. We found that living at higher elevations is positively associated with greater suicide rates. Although the rates are significantly greater as elevation increases, a clear linear relationship is not apparent, likely because of the interplay of socioeconomic factors, including urbanicity. The effect of chronic hypobaric hypoxia on mood cannot be ruled out, although the existence of causal mechanisms remains to be elucidated.
