Suicidal behaviours in South East London: prevalence, risk factors and the role of socio-economic status

Latent groups from multidimensional factors and effects on suicidal ideation in older adults

BACKGROUND

Suicide is a serious social problem among older adults. However, little is known about how multidimensional factors affect suicide of older adults.

AIMS

We classify the multidimensional suicidal risk types of older adults based on their characteristics and identify differences in suicidal ideation.

METHOD

Data were obtained via a nationwide online survey targeting 612 older adults over the age of 55 years. A latent profile analysis identified three profiles, one of which represented the optimal situation for these adults.

RESULTS

We identified three distinct multidimensional suicidal risk types in older adults: high-risk predicament (24.5%), moderate-risk predicament (57.7%) and abundant internal/external resources (17.8%). In particular, depression, a major risk factor for suicide, was found together with self-neglect in each group. Multiple regression analysis showed that older adults in the moderate-risk predicament and high-risk predicament groups were more likely to have suicidal ideation than those in the abundant internal/external resources group.

CONCLUSIONS

Our findings suggest that co-occurrence of depression and self-neglect represents a suicide risk pattern in high-risk older individuals. Therefore, local communities need to urgently screen and provide interventions for such older adults and strengthen their capacity for multidimensional aspects of life to prevent suicide in the long term.

Suicide attempts in the adult Mexican population: an analysis of sociodemographic characteristics and associated factors

OBJECTIVE

Suicide is the culmination of a process or continuum known as suicidal behavior that proceeds from ideation and planning to attempt. The objective was to estimate the prevalence of suicide attempts in the adult Mexican population and to analyze their main associated factors.

METHODS

We conducted an observational, cross-sectional, and descriptive study with information from the National Health and Nutrition Survey (2018). Self-reported lifetime suicide attempt was used in the analysis. We analyzed depression, obesity, tobacco smoking, and alcohol consumption as suicide attempt-associated factors using a multivariate logistic regression model.

RESULTS

The prevalence of adult suicide attempt was 2.0% (95%CI 1.8-2.2) and it was higher among women (2.4%; 95%CI 2.2-2.8) and young people (2.9%; 95%CI 2.4-3.4). Low education (OR=1.6; 95%CI 1.2-2.2), being single (OR=1.3; 95%CI 1.0-1.6), having obesity (OR=1.4; 95%CI 1.1-1.8), consumption of alcohol (OR=2.4; 95%CI 1.7-3.4) or tobacco smoking (OR=1.8; 95%CI 1.4-2.4), and having strong symptoms of depression (OR=10.1; 95%CI 6.2-16.3) were associated with a higher prevalence of suicide attempts.

CONCLUSION

These results help better understand suicidal behavior in Mexico and identify the factors that increase the likelihood of suicide attempts, which is essential to help reduce suicide mortality. This research is crucial for developing early interventions and prevention programs aimed at reducing suicide's public health burden.

A multisite comparison using electronic health records and natural language processing to identify the association between suicidality and hospital readmission amongst patients with eating disorders

OBJECTIVES

To describe and compare the association between suicidality and subsequent readmission for patients hospitalized for eating disorder treatment, within 2 years of discharge, at two large academic medical centers in two different countries.

METHODS

Over an 8-year study window from January 2009 to March 2017, we identified all inpatient eating disorder admissions at Weill Cornell Medicine, New York, USA (WCM) and South London and Maudsley Foundation NHS Trust, London, UK (SLaM). To establish each patient's-suicidality profile, we applied two natural language processing (NLP) algorithms, independently developed at the two institutions, and detected suicidality in clinical notes documented in the first week of admission. We calculated the odds ratios (OR) for any subsequent readmission within 2 years postdischarge and determined whether this was to another eating disorder unit, other psychiatric unit, a general medical hospital admission or emergency room attendance.

RESULTS

We identified 1126 and 420 eating disorder inpatient admissions at WCM and SLaM, respectively. In the WCM cohort, evidence of above average suicidality during the first week of admission was significantly associated with an increased risk of noneating disorder-related psychiatric readmission (OR 3.48 95% CI = 2.03-5.99, p-value < .001), but a similar pattern was not observed in the SLaM cohort (OR 1.34, 95% CI = 0.75-2.37, p = .32), there was no significant increase in risk of admission. In both cohorts, personality disorder increased the risk of any psychiatric readmission within 2 years.

DISCUSSION

Patterns of increased risk of psychiatric readmission from above average suicidality detected via NLP during inpatient eating disorder admissions differed in our two patient cohorts. However, comorbid diagnoses such as personality disorder increased the risk of any psychiatric readmission across both cohorts.

PUBLIC SIGNIFICANCE

Suicidality amongst is eating disorders is an extremely common presentation and it is important we further our understanding of identifying those most at risk. This research also provides a novel study design, comparing two NLP algorithms on electronic health record data based in the United States and United Kingdom on eating disorder inpatients. Studies researching both UK and US mental health patients are sparse therefore this study provides novel data.

Lethal Lust: Suicidal Behavior and Chemsex-A Narrative Review of the Literature

Chemsex is described as the use of certain drugs-commonly methamphetamine, gamma-butyrolactone (GBL)/gammahydroxybutyrate (GHB), and mephedrone-before or during planned sexual activity primarily among men who have sex with men (MSM). Evidence shows that MSM who engage in chemsex are at increased risk of physical harm, such as sexually transmittable infections (STIs), and are more likely to experience mental health symptoms. To further assess this, we reviewed the recent literature to evaluate whether the psychological impact of chemsex behavior includes suicidal ideation and suicidal attempts. Pubmed/MEDLINE was searched for articles reporting suicidal ideation and behavior among chemsex users with the terms "chemsex", "sexualized drug use", "suicide", and "mental health". Twelve articles (three case reports and nine cross-sectional studies) were included in the final narrative review. Overall, we retrieved mixed results regarding the relationship between chemsex practice and suicidality outcomes. Considering the inhomogeneous nature of the studies, the findings indicate that suicidality could be an issue of concern among MSM in general but among chemsex users in particular. Possible risk factors for suicidality among chemsex participants may include adversities experienced due to one's sexual orientation and an increased risk for HIV and other STI infections and the resulting negative impact on mental well-being. These aspects warrant further investigations.

The relationship between causes of suicidal attempts in Iran and individual and social variables: a retrospective study

OBJECTIVE

Determine the prevalence of suicide attempts and the relationships between the different causes of attempts with sociodemographic and clinical characteristics among individuals in Iran.

METHODS

A retrospective review of data about suicide attempts from poisoning care centers in Babol city between 2017 and 2021. Multinomial regression analysis (with mental illness being the reference variable) was used to determine the factors associated with the different causes of suicide attempts (addiction, romantic relationship problems, and economic problems).

RESULTS

The overall prevalence of completed suicide in the population sampled was 10.8% (95% confidence interval 9.5-12.1) (244/2,263). Relative to mental disorder, given that other variables in the model are held constant the following were associated with suicide attempts. A previous history of suicide attempts was associated with increasing the relative risk ratio of attempting suicide while having no positive history of smoking was associated with reducing the relative risk ratio of a suicidal attempt. However, the use of multiple drugs to attempt suicide was associated with an increased relative risk ratio of attempting suicide with romantic relationship problems and addiction as causes of suicide attempts. The first year of data collection (2017) and the female gender were both associated with an increased relative risk ratio of having a suicide attempt due to romantic relationships and economic problems. A family history of suicide was associated with an increased relative risk ratio of suicide attempts due to romantic relationship problems. However, using Pesticides-aluminum phosphide and detergent and javel water to attempt reduced the relative risk ratio of attempting due to romantic relationship problems. Age, self-employment, middle income, and married were associated with an increased relative risk ratio of suicide attempts among individuals due to addiction. However, staying longer at the emergency department was associated with a reduced relative risk ratio of having had a suicide attempt due to addiction.

CONCLUSIONS

This study highlights the interplay between romantic hardships, addiction, economic hardships as reasons for suicide attempts and various sociable variables in a population in Northern Iran. The most associated reason for suicide attempts was romantic relationship hardships. Therefore, interventions such as sessions on conflict resolution, boundary setting, and management of grieving would greatly benefit this society and reduce the rate of suicide, especially among individuals with a history of suicide attempts.

Long-term health conditions in UK working-age adults: a cross-sectional analysis of associations with demographic, socioeconomic, psychosocial and health-related factors in an inner-city population

OBJECTIVES

To study the overall disease prevalence, and associations between demographic, socioeconomic, psychosocial, and health-related factors, and self-reporting one or more long-term health conditions (LTCs) in a working-age inner-city population.

DESIGN

Cross-sectional household-based survey with a follow-up timepoint.

SETTING

South-East London Community Health survey data.

PARTICIPANTS

893 adults aged 16-64 years living in Lambeth and Southwark, London.

OUTCOME MEASURES

Prevalence estimates of individual and multiple LTCs. Multinomial logistic regression was used to analyse the association of demographic, socioeconomic, psychosocial and health-related indicators with having one and multiple LTCs at two timepoints.

RESULTS

More than one third of participants reported at least one LTC, with the most prevalent being musculoskeletal conditions and asthma. The prevalence of one LTC at both timepoints was 20.6% and 21.4%, and of multimorbidity was 14.0% and 16.4%. At both timepoints, the 35-44 age group showed the largest increase in prevalence of one LTC compared with the preceding age group (16-34). After adjusting for age and gender, small social networks and a larger number of stressful life events were associated with increased risk of having both one and multiple LTCs. The risk of multimorbidity was greater than for initial LTCs for small social networks (3.8 (95% CI: 1.8 to 7.8) compared with 2.0 (95% CI: 1.0 to 3.9)), and three to five stressful life events (3.0 (95% CI: 1.7 to 5.3) compared with 1.5 (95% CI 1.0 to 2.2)).

CONCLUSIONS

In this study, the prevalence of multimorbidity increased more than the prevalence of one LTC between the two timepoints, indicating a progression of the overall disease prevalence over time. The 35-44 age group showed the greatest increase in the number of initial LTCs which support health-promotion interventions targeting younger age groups. Focusing on increasing social support networks and treating the psychological impact of stressful life events may also be of benefit.

Prevalence of Suicidality in the European General Population: A Systematic Review and Meta-Analysis

OBJECTIVE

To conduct a systematic review and meta-analysis of the prevalence and variability in suicidality in the general adult population of Europe between 2008 and 2017.

METHODS

Studies containing original data on suicidality were identified in five electronic databases. Point, 12-month and lifetime prevalences were calculated for various types of suicidality. Pooled prevalence rates were calculated using a random effects model. Subgroup analysis and multivariate meta-regression were also performed.

RESULTS

We identified 24 papers containing original data, which provided 97 prevalence rates for suicidality. The pooled point prevalence rate was 3.96% (2.37-5.56), pooled 12-month prevalence 2.9% (1.49-4.32), and pooled lifetime prevalence 5.55% (4.31-6.79). The subgroup analysis showed that lifetime prevalence figures for wishing to be dead and suicidal ideation were higher in areas with a population of less than 3,849 inhabitants and in Eastern Europe. Finally, the multivariate meta-regression showed differences with respect to the period and type of suicidality, lower and upper age thresholds, population size, and study area.

CONCLUSION

Our data showed that approximately 21% of European individuals have wished to be dead at some point during their lifetime. Studies like this are necessary to highlight the need for efforts to prevent and intervene in suicidality.

Exploring the role of loneliness in relation to self-injurious thoughts and behaviour in the context of the integrated motivational-volitional model

Suicide is a worldwide public health concern claiming approximately 800,000 lives around the world every year. The impact of loneliness on mental and physical wellbeing has received increasing attention in recent years, however its role in the emergence of self-injurious thoughts and behaviours is unclear. The current study explored loneliness in relation to other psychological variables associated with self-injurious thoughts and behaviour. Data were collected from UK residents (n = 400, aged 18-76 years) via an online survey accessible between September 2018 and April 2019. Univariate multinomial logistic regression analyses identified that loneliness independently distinguished between participants with no history of self-injurious thoughts or behaviours, those with a history of self-injurious thoughts only, and those with a history of self-injurious behaviours. When other key variables were controlled for, loneliness distinguished between controls and those with a self-injurious thoughts or behaviours history. However, loneliness did not distinguish between people with self-injurious thoughts only and those with a history of self-injurious behaviours. To understand how loneliness might contribute towards the emergence of self-injury, analysis exploring the extent to which loneliness moderates established risk factors (e.g., defeat, entrapment) was conducted. The results suggest that loneliness moderates both the relationship between defeat and entrapment, and between entrapment and self-injurious thoughts. Future work exploring these associations prospectively would advance understanding of the role of loneliness in suicide risk and inform the development of clinical and community-based suicide prevention interventions.

Outcomes of community-based suicide prevention program in primary health care of Iran

Background

Suicidal management and prevention in communities, especially in its first stages, is an effective intervention for the health systems. However, in numerous societies most cases go undetected. Primary Health Care (PHC) is an effective place for the management of Suicide Prevention Programs (SPP). In Malekan County, a health community assessment found suicide as the most important health problem. A regional SPP was performed for suicide prevention during 2014–2017.

Methods

This study was carried out in six steps: (1) Establishing a research team, (2) Improving a registry for suicidal behaviors (SBs), (3) Identifying local determinants of SBs, (4) Training healthcare providers, (5) Follow-up and monitoring of SBs, and (6) Public awareness campaigns. Our ultimate goal was to lower the rates of suicide, and suicide attempt (SA) by 15 and 20 %, respectively. Multiple logistic regression was used to estimate the adjusted odds ratios and the 95% confidence intervals.

Results

A total of 821 SAs and 32 suicides were identified. The gender distribution for suicides was 70% males whereas SAs were 64% among females. The majority of suicides occurred in spring 18 (56.25%) while summer was the most common season among SAs 288 (35.8%). Almost 62 and 75% of suicides and SAs have used hanging and poisoning methods, respectively. Hanging increased suicide risk significantly (OR: 8.5, 95% CI 2.9–76.99). During the study, 93 life-skill and parenting education sessions were held. The incidence rates of suicide and SA decreased from 11.22, and 203 per 100,000 in 2013 to 2.63, and 157 in 2017, respectively. Similarly, the re-attempt to SAs ratio decreased from 12% to 2013 to 6.7% in 2017. Moreover, more than 8% of SBs were collected from adjacent Counties.

Conclusions

At the study end, suicide, SA, and re-attempt were lowered by 75%, 22%, and 42%, respectively. The practical framework that achieved in this study could be used as a basis for developing future SPPs and suicide researches in the Iranian context. Furthermore, the various socio-economic and socio-cultural challenges highlight the need to consider a wide range of contextual factors when developing an SPP.

A longitudinal study of suicide and suicide attempt in northwest of Iran: incidence, predictors, and socioeconomic status and the role of sociocultural status

Background

A detailed community-level understanding of socioeconomic status (SES) and sociocultural status (SCS) of suicides and suicide attempters (SAs) in a prospective design could have significant implications for policymakers at the local prevention and treatment levels. The effect of SCS and SES on SAs is poorly understood and investigated in Iran. The present study aimed to investigate the incidence, trend, and role of SES and SCS on suicide and SAs.

Methods

A longitudinal study was conducted based on the registry for SAs in Malekan County, Iran, from 2015 to 2018. Demographic characteristics, SES, SCS, incidence rates, and predictors of suicidal behaviors were measured via structured instruments. Simple and multiple logistic regressions were used to estimate crude and adjusted odds ratios (ORs) and 95% confidence intervals (CIs).

Results

A total of 853 SAs (32 suicides and 821 attempts) were identified during the study. Trend analysis revealed that the suicide rate significantly decreased from 2014 (10.28) to 2018 (1.75) per 100,000. In the final multiple variable models, age (26–40), male sex, unemployment, antisocial activities, history of SA, hanging method, and season (spring) increased the suicide risk while religious commitment had protective effects on suicide.

Conclusions

Our findings indicated that demographic characteristics, low SES, and SCS are associated with suicide. In this county, trend of suicide and SA were decreased from 2014 to 2018. This study findings highlight the need to consider a wide range of contextual variables, socio-demographic, SES, and SCS in suicide prevention strategies. Improving inter-sectoral collaborations and policymakers’ attitudes are imperative for SA reduction.

The effect of low childhood income on self-harm in young adulthood: Mediation by adolescent mental health, behavioural factors and school performance

Low childhood income is an established risk factor of self-harm in adolescence and young adulthood, and childhood income is additionally associated with various correlates of self-harm. How these correlates, such as psychiatric disorders, substance abuse, violent behaviour and school problems, mediate the effect of childhood income on self-harm, is less understood. The purpose of the current paper is to examine this mediation. The study is based on administrative register data on all Finnish children born in 1990–1995. An analytical sample of 384,121 children is followed from age 8 to 22. We apply the parametric g-formula to study the effect of childhood income on the risk of self-harm in young adulthood. Adolescent psychiatric disorders, substance abuse, prior self-harm, violent criminality and victimization, out-of-home placements, not being in education, employment or training and school performance are considered as potential mediators. We control for confounding factors related to childhood family characteristics. As a hypothetical intervention, we moved those in the lowest childhood income quintile to the second-lowest quintile, which resulted in a 7% reduction in hospital-presenting self-harm in young adulthood among those targeted by the intervention (2% reduction in the total population). 67% of the effect was mediated through the chosen mediators. The results indicate that increases in childhood material resources could protect from self-harm in young adulthood. Moreover, the large proportion of mediation suggests that targeted interventions for high-risk adolescents may be beneficial. To our knowledge, this is the first paper to use the parametric g-formula to study youth self-harm. Future applications are encouraged as the method offers several further opportunities for analysing the complex life course pathways to self-harm.

•

We study mediation in the association between low childhood income and self-harm.

•

Effects of a hypothetical intervention are examined.

•

Most of the effect of low childhood income on the risk of self-harm is indirect.

•

Distinct pathways are identified.

•

The parametric g-formula offers further avenues for self-harm research.

"There Is So Much More for Us to Lose If We Were to Kill Ourselves": Understanding Paradoxically Low Rates of Self-Harm in a Socioeconomically Disadvantaged Community in London

London has unexpectedly low overall rates of self-harm in public health data and contains highly deprived areas with these paradoxically low rates. Qualitative data were collected via interviews and focus groups with 26 individuals living and working in one such area. Using the Stress Process Model, we explore why this ethnically diverse community, which is exposed to multiple, chronic stressors, might nonetheless appear to have low rates of self-harm. Participants described significant impacts of stressors on the mental health of people locally. These were partly buffered by social resources related to community solidarity and a culture of self-reliance. However, identifying oneself as mentally ill through being known to have self-harmed was seen as highly risky, diminishing a person's social status and exposing them to additional stressors from the community and services. Consequently, people tended to hide distress, respond with behaviors less linked to mental illness, and avoid mental health services.

Characteristics and risk of repeat suicidal ideation and self-harm in patients who present to emergency departments with suicidal ideation or self-harm: A prospective cohort study

BACKGROUND

Characteristics and outcomes of patients presenting to Emergency Departments (EDs) have been under-examined. This paper describes the characteristics and risk of repeat suicidality amongst patients presenting to EDs with (1) suicidal ideation and (2) self-harm, compared to (3) controls in mental health crisis.

METHODS

The Clinical Record Interactive Search tool identified 2211 patients who presented to three London EDs with suicidal ideation or self-harm, and 1108 control patients. All patients received a full psychosocial assessment. Chi-squared tests examined group characteristics. Cox regression models assessed the risk of re-presentation with suicidal ideation or self-harm within one year.

RESULTS

There were a higher proportion of females and individuals under the age of 25 in the self-harm group. Patients presenting with suicidal ideation or self-harm were more likely to be white, live in more deprived areas, and less likely to receive a psychiatric diagnosis within one year compared to controls. Risk of repeat suicidality within one year was 3-4 times higher in those with baseline suicidal ideation (adjusted HR = 3.66, 95% CI 2.44-5.48) or self-harm (HR = 3.53 95% CI 2.47-5.04) compared to controls.

LIMITATIONS

To be included patients needed to have a full psychosocial assessment. Incomplete records meant 21.4% of the sample was excluded. This will have introduced bias which might confound observed associations.

CONCLUSION

Individuals presenting with either suicidal ideation or self-harm have similar risk for re-presentation within one year. Both groups would benefit from personalised risk management plans and active follow-up to reduce the risk of repeat suicidal behaviour.

Determinants of Suicidality in the European General Population: A Systematic Review and Meta-Analysis

Close to one million people commit suicide each year, with suicidal attempts being the main risk factor for suicide. The aim of this systematic review and meta-analysis is to achieve a greater understanding of suicidality in the general population of Europe by studying associated factors and their statistical significance with suicidality, as well as the effect of the temporal moment in which suicidality is observed in a relationship. A search strategy was carried out in electronic databases: Proquest's Psychology Database, Scopus, PsycINFO, Medline and Embase. Odds ratios (ORs), publication bias, influential studies on heterogeneity and analysis moderators were calculated. Twenty-six studies were included after meeting the inclusion criteria. Factors statistically associated with suicidality are female gender, age over 65 years, unemployment, low social support, adulthood adversity, childhood adversity, family history of mental disorder, any affective disorder, major depression, anxiety/stress/somatoform disorders, tobacco and substance use, any mental disorder and body mass index. As a limitation, a high heterogeneity between studies was found. Factors associated with suicidality in the general population are relevant for understanding the suicidal phenomenon.

Prevalence and correlates of suicidality in Andalusia (Spain): Results of the epidemiological study PISMA-ep

BACKGROUND

Suicidality is an important public health problem. Hence, the aims of this study are to report prevalence rates and correlates of suicidality in Andalusia (Southern Spain).

METHODS

This is a cross-sectional household survey conducted on a representative sample of adults living in Andalusia. 4507 subjects were interviewed using the Mini International Neuropsychiatric Interview (MINI) to assess suicidality and standardized instruments were employed to evaluate associated variables. A multivariate logistic regression analysis was used to explore independent associations with suicidality.

RESULTS

Current prevalence of suicidality was 6.4%, 4.4% showed death wish, 1.4% had ideas of self-harm, 2.4% had suicidal thoughts, 1.1% had a suicidal plan, 0.6% had attempted suicide during the month prior to the interview, and, lastly, 2.6% reported to have had any sort of suicide attempt during his/her previous life. Independent factors associated with suicidality were being female, older age, not having a stable couple, lower levels of social support, having had physical childhood abuse experience, having experienced an increasing number of stressful life events, higher neuroticism scores, having a family history of mental disorder and nicotine or drugs dependence.

LIMITATIONS

The instrument employed to measure suicidality is a screening tool rather than a more in-depth diagnostic measure. We have not included all potential correlates of suicidality. This is a cross-sectional study which cannot establish causal relationships between exposures and outcomes.

CONCLUSIONS

This is the first epidemiological study in Andalusia on suicidality offering important results of clinical interest for suicide prevention.

Suicidal Ideation and Attempt among Homeless People: a Systematic Review and Meta-Analysis

Globally, suicide is a major public health problem among homeless people. Suicidal ideation and attempt are remarkably higher among homeless people as compared to the general population and they are linked with greater risk of complete suicide. However, no systematic review and meta-analysis has been conducted to report the consolidated magnitude of suicidal ideation and attempt among homeless people. We searched PubMed, Embase, and Scopus to identify pertinent studies on suicidal ideation and attempt among homeless people. A meta-analysis of the studies was conducted using a random effect model. We also conducted a sensitivity analysis and Cochran's Q- and the I² test was employed to evaluate heterogeneity. Publication bias was assessed by Egger's test and visual inspection of the symmetry in funnel plots. In total, 20 eligible studies with 27,497 homeless people matched the inclusion criteria. Nineteen studies assessed suicidal attempt and thirteen studies assessed suicidal ideation among homeless people. The pooled current and lifetime prevalence of suicidal ideation was 17.83% (95% CI;10.73-28.14) and 41.60% (95% CI; 28.55-55.95), respectively whereas the pooled current and lifetime prevalence of suicidal attempt was 9.16% (95% CI;4.10-19.20) and 28.80% (95% CI; 21.66-37.18), respectively. We found a considerable heterogeneity between the studies, but we found no significant publication bias. The current review revealed a remarkably higher magnitude of suicidal ideation and attempt among homeless people as compared to the estimated prevalence in the general population. The concerned stakeholders need to give attention to address this problem emphasizing more on prevention and treatment strategies as well as utilizing holistic approaches to address the potential predictors of suicide among homeless people including physical, mental, and substance use problems.

Differences in hospital admissions practices following self-harm and their influence on population-level comparisons of self-harm rates in South London: an observational study

OBJECTIVES

To compare the proportions of emergency department (ED) attendances following self-harm that result in admission between hospitals, examine whether differences are explained by severity of harm and examine the impact on spatial variation in self-harm rates of using ED attendance data versus admissions data.

SETTING

A dataset of ED attendances and admissions with self-harm to four hospitals in South East London, 2009-2016 was created using linked electronic patient record data and administrative Hospital Episode Statistics.

DESIGN

Proportions admitted following ED attendance and length of stay were compared. Variation and spatial patterning of age and sex standardised, spatially smoothed, self-harm rates by small area using attendance and admission data were compared and the association with distance travelled to hospital tested.

RESULTS

There were 20 750 ED attendances with self-harm, 7614 (37%) resulted in admission. Proportion admitted varied substantially between hospitals with a risk ratio of 2.45 (95% CI 2.30 to 2.61) comparing most and least likely to admit. This was not altered by adjustment for patient demographics, deprivation and type of self-harm. Hospitals which admitted more had a higher proportion of admissions lasting less than 24 hours (54% of all admissions at highest admitting hospital vs 35% at lowest). A previously demonstrated pattern of lower rates of self-harm admission closer to the city centre was reduced when ED attendance rates were used to represent self-harm. This was not altered when distance travelled to hospital was adjusted for.

CONCLUSIONS

Hospitals vary substantially in likelihood of admission after ED presentation with self-harm and this is likely due to the differences in hospital practices rather than in the patient population or severity of self-harm seen. Public health policy that directs resources based on self-harm admissions data could exacerbate existing health inequalities in inner-city areas where these data may underestimate rates relative to other areas.

Spatial patterning of self-harm rates within urban areas

PURPOSE

Urban areas are usually found to have higher rates of self-harm, with deprivation the strongest predictor at area-level. We use a disease mapping approach to examine how self-harm is patterned within an urban area and its associations with deprivation, urbanness and ethnicity.

METHODS

Data from clinical records on individuals admitted for self-harm for 725 small areas in South East London were included. Bayesian hierarchical models explored the spatio-temporal patterns of self-harm admission rates and potential associations with proximity to city centre, population density, percentage greenspace and non-white ethnic-minority populations. All models were adjusted for area-level deprivation, social fragmentation and hospital of admission.

RESULTS

There were 8327 first admissions for self-harm during the study period. Self-harm admission rates varied fourfold across the study area, with lower rates close to the city centre [adjusted standardised admission ratio, closest versus furthest quartile 0.71(95% CrI 0.54-0.96)]. Deprivation was associated with self-harm but partially masked rather than explained the spatial pattern, which strengthened after adjustment. After adjustment for deprivation, hospital of admission and social fragmentation, greenspace, population density and ethnicity were not associated with self-harm rates.

CONCLUSION

Proximity to the city centre was associated with lower rates of self-harm, but the usual operationalisations of urbanness, population density and greenspace, were not. Deprivation did not explain the spatial patterning, nor did ethnicity. While nationally self-harm rates are higher in urban and deprived areas, this cannot be extrapolated to mean that within cities the inner-city is the highest risk area nor that risk will be principally patterned according to deprivation.

Examining the Contributions of Disability to Suicidality in the Context of Depression Symptoms and Other Sociodemographic Factors

We examined the contribution of disability status to suicidality when accounting for depression and sociodemographic risk factors in 438 American adults, 82 (18.7%) of whom identified as having disabilities. Participants with disabilities had significantly higher depression scores and were more likely to be unemployed and unpartnered, all of which were also associated with increased suicidality. However, disability remained a significant predictor of suicidality even when depression and sociodemographic risk factors were accounted for in a linear regression. Other significant predictors of suicidality in this regression were female gender, depression symptoms, and family and friend suicide history; identifying as a member of a religion was a significant protective factor against suicidality. Our findings suggest that the contribution of disability to suicidality goes beyond that which can be explained by increased depression symptoms and sociodemographic vulnerability.

Differentiation of direct and indirect socioeconomic effects on suicide attempts in South Korea

Despite the wide recognition of the inverse association between socioeconomic position (SEP) and suicidal behaviors, its underlying process and potential mediators are little known. This study investigated the pathway from SEP to suicide attempts with attention to potential mediators.From the Korean Health and Nutrition Examination Survey 2007-2013, which is a nationwide cross-sectional survey of the health and nutritional status, a total of 34,565 participants (≥30 years) were included in the analysis. To unfold the pathways linking SEP to suicide attempts, the direct and indirect effects of 3 SEP measures (educational attainment, household income, and occupational group) and 3 mediators (physical illness, mental health problems, and problematic drinking) were differentiated using structured equation model (SEM).Most of direct and indirect effects of educational attainment, household income, and occupational group on suicide attempts were significant; Nonemployment status had the largest total (β = 0.291, P < .01) and direct effects (β = 0.212, P < .01), while educational attainment had the largest indirect effect (β = -0.124, P < .01). Educational attainment was mainly mediated by physical illness and problem drinking, whereas household income and occupational group were mainly mediated by anxious or depressed mood and problem drinking. Physical illness played a major role in explaining suicide attempts, compared to mental health problem and problem drinking.Overall, experience of socioeconomic disadvantage increased suicide attempts independently of mental and physical problems. An extension of suicide prevention program is required for comprehensively targeting people with general problems such as physical illness and low SEP, complemented to narrowly targeting high risk group with, such as mental health problem.

Validation of the child and youth resilience measure among South African adolescents

Resilience is a dynamic, interactive process between resources that contribute to safeguarding a person and the adversities they experience. Within this promotional framework of resilience, this study sought to validate the Child and Youth Resilience Measure (CYRM-28) among a sample of South African adolescents (N = 1854). Confirmatory factor analysis supported a superior level of fit for a 24-item, three-factor model (i.e., individual/social, familial, and community/spiritual). Internal consistency and test-retest reliability estimates at a 12-month interval (N = 648) supported the reliability of the scales. Higher scores on the scales were associated with feeling more connected at school, greater parental monitoring perceptions, and lower sexual risk, confirming the convergent and criterion validity of the instrument. Partial discriminative power was evidenced based on selected scale distinctions according to age and sex groupings. Collectively, the findings suggest the 24-item CYRM is a valid and reliable self-report measure to assess the availability of resources associated with resilience in South African youth.

Risk factors of suicide attempt among people with suicidal ideation in South Korea: a cross-sectional study

Background

Suicide is a serious public health concern worldwide, and the fourth leading cause of death in Korea. Few studies have focused on risk factors for suicide attempt among people with suicidal ideation. The aim of the present study was to investigate the risk factors and develop prediction models for suicide attempt among people with suicidal ideation in the Korean population.

Method

This study included 1567 men and 3726 women aged 20 years and older who had suicidal ideation from the Korea National Health and Nutrition Examination Survey from 2007 to 2012. Among them, 106 men and 188 women attempted suicide. Multivariate logistic regression analysis with backward stepwise elimination was performed to find risk factors for suicide attempt. Sub-group analysis, dividing participants into under 50 and at least 50 years old was also performed.

Results

Among people with suicidal ideation, age, education, cancer, and depressive disorder were selected as risk factors for suicide attempt in men. Age, education, national basic livelihood security, daily activity limitation, depressive disorder, stress, smoking, and regular exercise were selected in women. Area under curves of our prediction models in men and women were 0.728 and 0.716, respectively.

Conclusions

It is important to pay attention to populations with suicidal ideation and the risk factors mentioned above. Prediction models using the determined risk factors could be useful to detect high-risk groups early for suicide attempt among people with suicidal ideation. It is necessary to develop specific action plans for these high-risk groups to prevent suicide.

A comparative analysis of suicide attempts in left-behind children and non-left-behind children in rural China

To estimate the prevalence of suicide attempts and explore the shared and unique factors influencing suicide risk in left-behind children (LBC) and non-left-behind children (NLBC) in rural China, this study collected data using a multi-stage cluster random sampling method from 13,952 children including 6,034 LBC and 7,918 NLBC. Sociodemographic characteristics, suicide attempts, neglect and physical abuse, negative life events, and loneliness were measured by self-reported questionnaires. Data were analyzed using logistic regression models. Gender and mother's education level were unique influential factors for NLBC while family structure type was a unique influential factor for LBC. The study provides two novel findings regarding NLBC specifically: 1. Children with optimal family socioeconomic status are more likely to report suicide attempts (odds ratio OR = 1)than are those in the general children population, OR 0.52 (95% CI: 0.39-0.70), and 2. Children with higher mother's education level are subject to higher suicide rates in high school, OR 1.67 (95% CI: 1.13-2.46), and post-secondary education, OR 2.14 (95% CI: 1.37-3.37). The unique characteristics of LBC and NLBC in China suggest that investigating risk factors and determining the factors that might be targeted in intervention programs are urgently needed currently.

Major depressive disorder and suicidality in early HIV infection and its association with risk factors and negative outcomes as seen in semi-urban and rural Uganda

INTRODUCTION

There is a paucity of research into the psychiatric problems associated with early stage HIV clinical disease in sub-Saharan Africa.

METHODS

A cross sectional study was undertaken among 899 adult ART naïve persons in early stage HIV clinical disease (participants with CD4≥250 and who were at WHO clinical Stage I or II) attending a semi-urban and a rural clinic in Uganda.

RESULTS

The prevalence of major depressive disorder in this study was 14.0% [95% CI 11.7-6.3%] while that of 'moderate to high risk for suicidality' was 2.8% [95% CI 1.7%; 3.9%]. Multivariable analyses found that factors in the socio-demographic, vulnerability/protective and stress (only for major depressive disorder) domains were significantly associated with both major depressive disorder and 'moderate to high risk for suicidality'. Major depressive disorder but not 'moderate to high risk for suicidality' was significantly associated with impaired psychosocial functioning, greater utilisation of health services and non-adherence to septrin/dasone. Neither major depressive disorder nor 'moderate to high risk for suicidality' was associated with CD4 counts, risky sexual behaviour nor with non-utilisation of condoms.

LIMITATIONS

The bidirectional nature of some of the relationships between the investigated psychiatric problems, risk factors and outcomes in this cross sectional study makes it difficult to elucidate the actual direction of causality.

CONCLUSION

Early stage HIV clinical disease is associated with considerable major depressive disorder and 'moderate to high risk for suicidality'. Therefore there is a need to integrate mental health into HIV interventions that target early stage HIV disease.

Understanding women who self-harm: Predictors and long-term outcomes in a longitudinal community sample

OBJECTIVE

There is growing awareness of the range of psychosocial, lifestyle, and sociodemographic factors related to self-harm, however this research is often limited by using cross-sectional or convenience samples. And while we generally assume that young adults who self-harm experience poorer long-term outcomes, longitudinal research is needed. This paper builds on prior research using a large, representative, longitudinal sample.

METHODS

5765 Australian women completed 5 surveys (age 18-23 to 31-36). Six-month self-harm was measured by self-report. We had two aims: firstly to predict future self-harm, separately for women with and without prior self-harm. Secondly, to identify outcomes 3 and 6 years following self-harm.

RESULTS

Six-month self-harm prevalence was 2.5%. Predictors among women without recent self-harm included depression, dieting behaviours, number of male sexual partners, and abuse. Among women with recent or current self-harm, predictors were number of dieting behaviours, tiredness of life, and stress. Women who self-harmed reported poorer outcomes, namely greater difficulties in relationships at 3- and 6-year follow-up.

CONCLUSIONS

Longitudinal risk factors for self-harm differed depending on prior self-harm status, and included depression, dieting behaviours, tiredness of life and stress. These factors may serve as warning signs for new or continued self-harm. This study offers new insight into long-term outcomes up to six years after self-harm, particularly with relationships.

Gender-Specific Factors Associated with Suicide Attempts among the Community-Dwelling General Population with Suicidal Ideation: the 2013 Korean Community Health Survey

We identified traditional risk factors and investigated poorly understood risk factors for suicide attempts according to gender in a large Korean population. We analyzed the data from 6,768 males and 12,475 females with suicidal ideation obtained from the nationwide 2013 Korean Community Health Survey. The dependent variable was suicide attempts within the past year. There was a significant trend towards an increase in suicide attempts with decreasing age in both genders. Compared with those who were married, suicide attempts were significantly higher among those who were widowed, divorced, or separated for males (odds ratio [OR], 2.07; 95% confidence interval [CI], 1.34-3.20), but lower for females (OR, 0.66; 95% CI, 0.45-0.98). Current smoking and depression were significant risk factor for suicide attempts in males and females. However, monthly household income, myocardial infarction, and osteoporosis were significantly associated with suicide attempts only in males, whereas education level, recipient of National Basic Livelihood Security, family contact, leisure activity, and drinking frequency were significantly associated only in females. These findings indicate that gender difference should be considered in the assessment, prevention, and management of future suicide attempts by community policy-makers and clinicians.

Minority status and mental distress: a comparison of group density effects

BACKGROUND

It has been observed that mental disorders, such as psychosis, are more common for people in some ethnic groups in areas where their ethnic group is less common. We set out to test whether this ethnic density effect reflects minority status in general, by looking at three situations where individual characteristics differ from what is usual in a locality.

METHOD

Using data from the South East London Community Health study (n = 1698) we investigated associations between minority status (defined by: ethnicity, household status and occupational social class) and risk of psychotic experiences, common mental disorders and parasuicide. We used a multilevel logistic model to examine cross-level interactions between minority status at individual and neighbourhood levels.

RESULTS

Being Black in an area where this was less common (10%) was associated with higher odds of psychotic experiences [odds ratio (OR) 1.34 95% confidence interval (CI) 1.07-1.67], and attempted suicide (OR 1.84 95% CI 1.19-2.85). Living alone where this was less usual (10% less) was associated with increased odds of psychotic experiences (OR 2.18 95% CI 0.91-5.26), while being in a disadvantaged social class where this was less usual (10% less) was associated with increased odds of attempted suicide (OR 1.33 95% CI 1.03-1.71). We found no evidence for an association with common mental disorders.

CONCLUSIONS

The relationship between minority status and mental distress was most apparent when defined in terms of broad ethnic group but was also observed for individual household status and occupational social class.

Risk assessment and suicide by patients with schizophrenia in secondary mental healthcare: a case-control study

OBJECTIVES

To investigate the role of risk assessment in predicting suicide in patients with schizophrenia spectrum disorders (SSDs) receiving secondary mental healthcare. We postulated that risk assessment plays a limited role in predicting suicide in these patients.

DESIGN

Retrospective case-control study.

SETTING

Anonymised electronic mental health record data from the South London and Maudsley National Health Service (NHS) Foundation Trust (SLaM) (London, UK) linked with national mortality data.

PARTICIPANTS

In 242 227 SLaM service users up to 31 December 2013, 635 suicides were identified. 96 (15.1%) had a SSD diagnosis. Those who died before 1 January 2007 (n=25) were removed from the analyses. Thus, 71 participants with SSD who died from suicide over the study period (cases) were compared with 355 controls.

MAIN OUTCOME MEASURE

Risk of suicide in relation to risk assessment ratings.

RESULTS

Cases were younger at first contact with services (mean±SD 34.5±12.6 vs 39.2±15.2) and with a higher preponderance of males (OR=2.07, 95% CI 1.18 to 3.65, p=0.01) than controls. Also, suicide occurred within 10 days after last contact with services in half of cases, with the most common suicide methods being hanging (14) and jumping (13). Cases were more likely to have the following 'risk assessment' items previously recorded: suicidal history (OR=4.42, 95% CI 2.01 to 9.65, p<0.001), use of violent method (OR=3.37, 95% CI 1.47 to 7.74, p=0.01), suicidal ideation (OR=3.57, 95% CI 1.40 to 9.07, p=0.01) and recent hospital discharge (OR=2.71, 95% CI 1.17 to 6.28, p=0.04). Multiple regression models predicted only 21.5% of the suicide outcome variance.

CONCLUSIONS

Predicting suicide in schizophrenia is highly challenging due to the high prevalence of risk factors within this diagnostic group irrespective of outcome, including suicide. Nevertheless, older age at first contact with mental health services and lack of suicidal history and suicidal ideation are useful protective markers indicative of those less likely to end their own lives.

Does socioeconomic status moderate the relationships between school connectedness with psychological distress, suicidal ideation and attempts in adolescents?

OBJECTIVE

Research has indicated that school connectedness acts as a buffer against depressive symptoms and suicidality. However, little is known about the role of socioeconomic status (SES) on these links. The present study examined the moderating role of subjective SES and parental education on the relationships between school connectedness and psychological distress, suicidal ideation and suicide attempts.

METHODS

Data were gathered from 4955 participants within the 2013 cycle of the Ontario Students Drug Use and Health Survey, a province-wide repeated school-based survey of students in grade 7 to 12 across Ontario, Canada.

RESULTS

Results indicated that higher subjective SES is associated with high levels of school connectedness. Subjective SES is also a significant moderator of the association between school connectedness and psychological distress, but not between school connectedness and suicidal ideation or attempts. At low subjective SES, there was no difference in risk of psychological distress between students with high and low levels of school connectedness. However, at higher subjective SES, students with high levels of school connectedness have lower odds of psychological distress than those with low levels of school connectedness. The associations between school connectedness and each of the mental health outcomes did not significantly vary with parental education.

CONCLUSIONS

These findings suggest that the beneficial effects of school connectedness on mental health problems may be more strongly related to adolescents' status beliefs rather than parental education. Future research is needed to better understand the mechanism through which subjective SES and school connectedness influence psychological distress.

Opening the 'Vaccine Hesitancy' black box: how trust in institutions affects French GPs' vaccination practices

BACKGROUND

In recent years, vaccine hesitancy among health professionals has emerged as an important issue on public health agendas. However, we do not yet know very much about whether, and if so how, trust in institutions affects their practices.

METHODS

A path analysis model explaining the influence of trust on GPs' vaccine hesitancy was applied to a cross-sectional survey of 1,582 French GPs performed in 2014. We hypothesized that distrust in public health institutions influences GPs' concerns about the safety of various vaccines, their perceptions about the importance of vaccination, their self-efficacy in the doctor-patient relationship, and ultimately their vaccination recommendations to patients.

RESULTS

GPs' trust in institutions was found to be significantly associated with lower vaccine hesitancy, an association mediated to a large extent by the vaccine's perceived safety (β = 0.09, P < 0.01) and the importance of vaccination (β = 0.46, P < 0.001).

CONCLUSION

These results suggest that restoration of high vaccination coverage may require the re-establishment of a significant degree of trust in the public health system among health professionals.

Factors influencing attempted and completed suicide in postnatal women: A population-based study in Taiwan

The aims of study were to investigate risk factors associated with attempted and completed suicide. This nested case–control study was conducted using the medical and death data of nearly all pregnant women for the period 2002–2012 in Taiwan. A total of 139 cases of attempted suicide and 95 cases of completed suicide were identified; for each case, 10 controls were randomly selected and matched to the cases according to age and year of delivery. A conditional logistic regression model was used. The mean attempted and completed suicide rates were 9.91 and 6.86 per 100,000 women with live births, respectively. Never having married and postpartum depression also increased the risk of attempted suicide (OR = 2.06; 95% CI = 1.09–3.88 and OR = 2.51; 95% CI = 1.10–5.75, respectively) and completed suicide (OR = 20.27; 95% CI = 8.99–45.73 and OR = 21.72; 95% CI = 8.08–58.37, respectively). Other factors for attempted suicide included being widowed or divorced, and having a caesarean delivery or suicide history. Other factors for completed suicide included lower education level, low infant birth weight, and diagnosis of anxiety or mood disorder. These results suggest that people should appropriately assess potential risk factors and provide assistance for postnatal women to reduce the occurrence of suicide events.

A 6-year Longitudinal Study of Self-harm and Suicidal Behaviors among Chinese Adolescents in Hong Kong

STUDY OBJECTIVE

To examine the trajectories of self-harm and suicidal behaviors among Chinese adolescents in Hong Kong and to investigate the related predictors, including gender, family nonintactness, economic disadvantage, positive youth development, and family functioning.

DESIGN

We used quantitative data from a large sample of adolescent participants. Participants initially joined this study when they were in grade 7 (wave 1), and they were followed from grade 8 (wave 2) to grade 12 (wave 6).

SETTING, PARTICIPANTS, AND INTERVENTIONS

The participants consisted of 2023 grade 12 students from 28 secondary schools in Hong Kong. A multistage cluster random sampling method was adopted.

MAIN OUTCOME MEASURES

Self-harm and suicidal behaviors.

RESULTS

The trajectories of self-harm and suicidal behaviors in general declined from grade 7 to grade 12. Regarding the effect of gender, whereas adolescent girls showed a higher prevalence for self-harm and suicidal behaviors at baseline and other waves, adolescent boys showed a pronounced decline in self-harm rates. Adolescents from nonintact families were more likely to self-harm or engage in suicidal behaviors at wave 6. Economic disadvantage at wave 4 predicted higher suicidal behavior among adolescents but not self-harm at wave 6. Regarding positive youth development, several protective factors that include cognitive-behavioral competencies, prosocial attributes, general positive youth development qualities, and positive identity could help reduce self-harm and suicidal behaviors at different time points. Regarding the role of family functioning, more family conflicts predicted higher suicidality in adolescence (self-harm and suicidal behaviors), and family communication affected self-harming behaviors at wave 6.

CONCLUSION

The trajectories of self-harm and suicidal behaviors decline from early to late adolescence among Chinese adolescents. Positive youth development and constructive family functioning are critical to help reduce suicidal behaviors. Regarding increased risk, more attention should be paid to adolescent girls and adolescents from nonintact and economic disadvantaged families.

Self-harm and life problems: findings from the Multicentre Study of Self-harm in England

PURPOSE

Self-harm is a major clinical problem and is strongly linked to suicide. It is important to understand the problems faced by those who self-harm to design effective clinical services and suicide prevention strategies. We investigated the life problems experienced by patients presenting to general hospitals for self-harm.

METHODS

Data for 2000-2010 from the Multicentre Study of Self-harm in England were used to investigate life problems associated with self-harm and their relationship to patient and clinical characteristics, including age, gender, repeat self-harm and employment status.

RESULTS

Of 24,598 patients (36,431 assessed episodes), 57% were female and with a mean age of 33.1 years (SD 14.0 years), 92.6% were identified as having at least one contributing life problem. The most frequently reported problems at first episode of self-harm within the study period were relationship difficulties (especially with partners). Mental health issues and problems with alcohol were also very common (especially in those aged 35-54 years, and those who repeated self-harm). Those who repeated self-harm were more likely to report problems with housing, mental health and dealing with the consequences of abuse.

CONCLUSIONS

Self-harm usually occurs in the context of multiple life problems. Clinical services for self-harm patients should have access to appropriate care for provision of help for relationship difficulties and problems concerning alcohol and mental health issues. Individualised clinical support (e.g. psychological therapy, interventions for alcohol problems and relationship counselling) for self-harm patients facing these life problems may play a crucial role in suicide prevention.

Self-harm and ethnicity: A systematic review

AIMS

This review will focus on the rates, clinical characteristics, risk factors and methods of self-harm and suicide in different ethnic groups in the United Kingdom, providing an update synthesis of recent literature.

METHODS

Studies that met the inclusion criteria between 2003 and 2013 were reviewed using the following databases: MEDLINE, PsycINFO, EMBASE and CINAHL. The methodological quality of each study was then assessed using a structured scoring system.

RESULTS

A total of 2,362 articles were retrieved, 10 of which matched the inclusion criteria were reviewed. Significant differences were found in the rates of self-harm between ethnic groups with Asian males being least likely to self-harm and Black females being most likely to self-harm. Also, Black and South Asian people were less likely to repeat self-harm. Factors that may help protect or predispose individuals to self-harm or attempt suicide (such as religion, mental health and coping styles) also differ between ethnic groups.

CONCLUSIONS

There are clear ethnic differences in self-harm and suicide, which may be affected by factors such as cultural pressures and prevalence of mental illness. An awareness of these differences is vital to help prevent further attempts of self-harm and suicide. Further research into differences between ethnic and cultural groups and self-harm continues to be important.

Suicidality and its relationship with depression, alcohol disorders and childhood experiences of violence: results from the ESEMeD study

BACKGROUND

Suicidality constitutes a major health concern in many countries. The aim of the present paper was to analyse 10 of its risk factors and their interdependence.

METHODS

Data on suicidality, mental disorders and experience of childhood violence was collected from 8796 respondents in the European Study of the Epidemiology of Mental Disorders (ESEMeD). The CIDI was used to assess mental disorders. Individuals were randomly divided into two subgroups. In one, a Graphical Markov model to predict suicidality was constructed, in the second, predictors were cross-validated.

RESULTS

Lifetime suicidality was predicted mainly by lifetime depression and early experiences of violence, with a pseudo R-square of 12.8%. In addition, alcohol disorders predicted suicidality, but played a minor role compared with the other risk factors in this sample.

CONCLUSION

In addition to depression, early experience of violence constitutes an important risk factor of suicidality.

LIMITATIONS

This is a cross-sectional and retrospective study assessing risk factors for suicidality, not for suicide itself.

Prevalence of suicidal ideation and suicide attempts in the general population of China: A meta-analysis

OBJECTIVE

The objective of this meta-analysis is to estimate the pooled prevalence of suicidal ideation and suicide attempts in the general population of Mainland China.

METHODS

A systematic literature search was conducted via the following databases: PubMed, PsycINFO, MEDLINE, China Journals Full-Text Databases, Chongqing VIP database for Chinese Technical Periodicals, and Wan Fang Data. Statistical analysis used the Comprehensive Meta-Analysis program.

RESULTS

Eight studies met the inclusion criteria for the analysis; five reported on the prevalence of suicidal ideation and seven on that of suicide attempts. The estimated lifetime prevalence figures of suicidal ideation and suicide attempts were 3.9% (95% confidence interval: 2.5%-6.0%) and 0.8% (95% confidence interval: 0.7%-0.9%), respectively. The estimated female-male ratio for lifetime prevalence of suicidal ideation and suicide attempts was 1.7 and 2.2, respectively. Only the difference of suicide attempts between the two genders was statistically significant.

CONCLUSION

This was the first meta-analysis of the prevalence of suicidal ideation and suicide attempts in the general population of Mainland China. The pooled lifetime prevalence of both suicidal ideation and suicide attempts are relatively low; however, caution is required when assessing these self-report data. Women had a modestly higher prevalence for suicide attempts than men. The frequency for suicidal ideation and suicide attempts in urban regions was similar to those in rural areas.

Suicide completion in secondary mental healthcare: a comparison study between schizophrenia spectrum disorders and all other diagnoses

BACKGROUND

Suicide completion is a tragic outcome in secondary mental healthcare. However, the extent to which demographic and clinical characteristics, suicide method and service use-related factors vary across psychiatric diagnoses remains poorly understood, particularly regarding differences between 'schizophrenia spectrum disorders (SSD)' and 'all other diagnoses', which may have implications for suicide prevention in high risk groups.

METHODS

308 patients who died by suicide over 2007-2011 were identified from the South London and Maudsley NHS Foundation Trust Biomedical Research Centre Case Register. Demographic, clinical, services use-related factors, 'full risk assessment' ratings and the Health of the Nation Outcome Scale (HONOS) scores were compared across psychiatric diagnoses. Specifically, differences between patients with and without SSD were investigated.

RESULTS

Patients with SSD ended their lives at a younger age, were more frequently of Black ethnicity and had higher levels of social deprivation than other diagnoses. Also, these patients were more likely to have HONOS and 'risk assessment' completed. However, patients who had no SSD scored significantly higher on 'self-injury' and 'depression' HONOS items and they were more likely to have the following 'risk assessment' items: 'suicidal ideation', 'hopelessness', 'feeling no control of life', 'impulsivity' and 'significant loss'. Of note, 'disengagement' was more common in patients with SSD, although they had been seen by the staff closer to the time of suicide than in all-other diagnoses. Whilst 'hanging' was the most common suicide method amongst patients with non-SSD, most service users with a SSD diagnosis used 'jumping' (from heights or in front of a vehicle).

CONCLUSIONS

Suicide completion characteristics varied between SSD and other diagnoses in patients receiving secondary mental healthcare. In particular, although clinicians tend to more frequently recognize suicide risk as a focus of concern in patients who have SSD, who are therefore more likely to have a detailed risk assessment documented; 'known' suicide risk factors appear to be more relevant in patients with non-SSD. Hence, the classic suicide prevention model might be of little use for SSD.

Prevalence and correlates of disordered eating in a general population sample: the South East London Community Health (SELCoH) study

PURPOSE

Disordered eating has been shown to be more prevalent than full eating disorders diagnoses. However, research on its prevalence, socio-demographic, psychological correlates, and patterns of service use in multi-ethnic samples is still limited. This paper explores these associations in a South London-based (UK) sample.

METHODS

The South East London Community Health (SELCoH) study is a general population survey (N = 1,698) of individuals aged 16+. Disordered eating was defined as ≥2 positive answers at the SCOFF questionnaire. Crude and adjusted logistic and multinomial logistic regression models were fit to investigate associations between socio-demographic characteristics, disordered eating, psychiatric comorbidity, and service use.

RESULTS

A total of 164 (10 %) participants reported disordered eating and the majority were from ethnic minorities. In adjusted models, Asian ethnicity was associated with purging, loss of control eating and preoccupation with food. Individuals with disordered eating had higher odds of screening positive for post-traumatic stress disorder and personality disorders and of having anxiety/mood disorders, suicidal ideation/attempts, hazardous levels of drinking, and used drugs in the previous year. Only 36 % of individuals with disordered eating had sought professional help in the previous 12 months mostly through their general practitioner (27.4 %), followed by psychotherapists (12.8 %) and mental health specialists (5.5 %).

CONCLUSION

This study found a high prevalence of disordered eating, especially amongst ethnic minorities, and associations with a number of psychiatric conditions. Overall few participants accessed specialist services. These findings suggest that both disordered eating manifestations amongst ethnic minorities and access to care need better investigation.
