Social and psychiatric influences on urban-rural differentials in Australian suicide

Inequalities of Suicide Mortality across Urban and Rural Areas: A Literature Review

Suicide mortality is a major contributor to premature death, with geographic variation in suicide rates. Why suicide rates differ across urban and rural areas has not yet been fully established. We conducted a literature review describing the urban-rural disparities in suicide mortality. Articles were searched in five databases (EMBASE, PubMed, PsychINFO, Scopus, and Web of Science) from inception till 26 May 2021. Eligible studies were narratively analyzed in terms of the urban-rural disparities in suicides, different suicide methods, and suicide trends over time. In total, 24 articles were included in our review. Most studies were ecological and cross-sectional evidence tentatively suggests higher suicide rates in rural than in urban areas. Men were more at risk by rurality than women, but suicide is in general more prevalent among men. No obvious urban-rural pattern emerged regarding suicide means or urban-rural changes over time. Potential suicidogenic explanations include social isolation, easier access to lethal means, stigmatization toward people with mental health problems, and reduced supply of mental health services. For research progress, we urge, first, individual-level cohort and case-control studies in different sociocultural settings. Second, both rurality and urbanicity are multifaceted concepts that are inadequately captured by oversimplified typologies and require detailed assessments of the sociophysical residential environment.

Suicide in rural Australia: A retrospective study of mental health problems, health-seeking and service utilisation

BACKGROUND

Suicide rates are higher in rural Australia than in major cities, although the factors contributing to this are not well understood. This study highlights trends in suicide and examines the prevalence of mental health problems and service utilisation of non-Indigenous Australians by geographic remoteness in rural Australia.

METHODS

A retrospective study of National Coronial Information System data of intentional self-harm deaths in rural New South Wales, Queensland, South Australia and Tasmania for 2010-2015 from the National Coronial Information System.

RESULTS

There were 3163 closed cases of intentional self-harm deaths by non-Indigenous Australians for the period 2010-2015. The suicide rate of 12.7 deaths per 100,000 persons was 11% higher than the national Australian rate and increased with remoteness. Among people who died by suicide, up to 56% had a diagnosed mental illness, and a further 24% had undiagnosed symptoms. Reported diagnoses of mental illness decreased with remoteness, as did treatment for mental illness, particularly in men. The most reported diagnoses were mood disorders (70%), psychotic disorders (9%) and anxiety disorders (8%). In the six weeks before suicide, 22% of cases had visited any type of health service at least once, and 6% had visited two or more services. Medication alone accounted for 76% of all cases treated.

CONCLUSIONS

Higher suicide rates in rural areas, which increase with remoteness, may be attributable to decreasing diagnosis and treatment of mental disorders, particularly in men. Less availability of mental health specialists coupled with socio-demographic factors within more remote areas may contribute to lower mental health diagnoses and treatment. Despite an emphasis on improving health-seeking and service accessibility in rural Australia, research is needed to determine factors related to the under-utilisation of services and treatment by specific groups vulnerable to death by suicide.

Urbanization and emerging mental health issues

Rapid urbanization worldwide is associated to an increase of population in the urban settings and this is leading to new emerging mental health issues. This narrative mini-review is based on a literature search conducted through PubMed and EMBASE. A total of 113 articles published on the issue of urban mental health have been selected, cited, reviewed, and summarized. There are emerging evidences about the association between urbanization and mental health issues. Urbanization affects mental health through social, economic, and environmental factors. It has been shown that common mental syndromes report higher prevalence in the cities. Social disparities, social insecurity, pollution, and the lack of contact with nature are some of recognized factors affecting urban mental health. Further reserach studies and specific guidelines should be encouraged to help policy makers and urban designers to improve mental health and mental health care facilities in the cities; additional strategies to prevent and reduce mental illness in the urban settings should be also adopted globally.

Systems modelling and simulation to inform strategic decision making for suicide prevention in rural New South Wales (Australia)

BACKGROUND

The need to understand and respond to the unique characteristics and drivers of suicidal behaviour in rural areas has been enabled through the Australian Government's 2015 mental health reforms facilitating a move to an evidence-based, regional approach to suicide prevention. However, a key challenge has been the complex decision-making environment and lack of appropriate tools to facilitate the use of evidence, data and expert knowledge in a way that can inform contextually appropriate strategies that will deliver the greatest impact. This paper reports the co-development of an advanced decision support tool that enables regional decision makers to explore the likely impacts of their decisions before implementing them in the real world.

METHODS

A system dynamics model for the rural and remote population catchment of Western New South Wales was developed. The model was based on defined pathways to mental health care and suicidal behaviour and reproduced historic trends in the incidence of attempted suicide (self-harm hospitalisations) and suicide deaths in the region. A series of intervention scenarios were investigated to forecast their impact on suicidal behaviour over a 10-year period.

RESULTS

Post-suicide attempt assertive aftercare was forecast to deliver the greatest impact, reducing the numbers of self-harm hospitalisations and suicide deaths by 5.65% (95% interval, 4.87-6.42%) and 5.45% (4.68-6.22%), respectively. Reductions were also projected for community support programs (self-harm hospitalisations: 2.83%, 95% interval 2.23-3.46%; suicide deaths: 4.38%, 95% interval 3.78-5.00%). Some scenarios produced unintuitive impacts or effect sizes that were significantly lower than what has been anticipated under the traditional evidence-based approach to suicide prevention and provide an opportunity for learning.

CONCLUSION

Systems modelling and simulation offers significant potential for regional decision makers to better understand and respond to the unique characteristics and drivers of suicidal behaviour in their catchments and more effectively allocate limited health resources.

Widening socioeconomic inequalities in Australian suicide, despite recent declines in suicide rates

PURPOSE

This study aims to investigate trends in socioeconomic inequalities of suicide from 1979 to 2013 for Australian males and females aged 15-34 years and 35-64 years.

METHODS

Data on suicides and population were obtained from national registries. An area-based measure of socioeconomic status (SES) was used, and categorized into low, middle, and high SES areas. Suicide rates for each SES groups were estimated using a negative binomial regression model, adjusted for confounders. Socioeconomic inequalities in suicide were assessed using absolute and relative risk of low-to-high SES areas. Secular changes in socioeconomic inequalities were assessed using trend tests for relative risk.

RESULTS

For young males, there was an increase in socioeconomic inequality driven by a significant decrease in suicide rates in high SES areas. For older males, inequality in suicide increased by 29%, which was related to a marked increase in suicide rates in low SES areas. Inequalities in both young and older female suicides also increased. These increases occurred when corresponding suicide rates in high SES areas decreased.

CONCLUSIONS

Recent widening socioeconomic inequalities in Australian suicide have been primarily associated with declines in suicide rates in high SES areas. However, an increasing inequality in older male suicide is linked with low SES. Efforts targeting people from poor areas, especially older males, should be considered when developing suicide prevention strategy.

Suicide in Castellon, 2009-2015: Do sociodemographic and psychiatric factors help understand urban-rural differences?

INTRODUCTION

Studies have pointed to rurality as an important factor influencing suicide. Research so far suggests that several sociodemograpic and psychiatric factors might influence urban-rural differences in suicide. Also, their contribution appears to depend on sex and age. Unfortunately, studies including a comprehensive set of explanatory variables altogether are still scare and most studies have failed to present their analyses split by sex and age groups. Also, urban-rural differences in suicide in Spain have been rarely investigated. The present study aimed at explaining rural-urban differences in suicidality in the province of Castellon (Spain). A comprehensive set of sociodemographic and psychiatric factors was investigated and analyses were split by sex and age.

MATERIAL AND METHOD

The sample comprised all suicides recorded in the province of Castellon from January 2009 to December 2015 (n=343). Sociodemographic data included sex, age, and suicide method. Psychiatric data included the history of mental health service utilization, psychiatric diagnosis, suicide attempts, and psychiatric hospitalization.

RESULTS

Consistent with past research, suicide rates were highest in rural areas, especially in men and older people. We also found that urban-rural differences in sociodemographic and psychiatric variables were sensitive to sex and age. Our results indicated that specialized mental health service use and accessibility to suicide means might help understand urban-rural differences in suicide, especially in men. When exploring urban-rural differences as a function of age, general practitioner visits for psychiatric reasons were more frequent in the older age group in rural areas.

CONCLUSIONS

Study implications for suicide prevention strategies in Spain are discussed.

Spatial clustering of fatal, and non-fatal, suicide in new South Wales, Australia: implications for evidence-based prevention

BACKGROUND

Rates of suicide appear to be increasing, indicating a critical need for more effective prevention initiatives. To increase the efficacy of future prevention initiatives, we examined the spatial distribution of suicide deaths and suicide attempts in New South Wales (NSW), Australia, to identify where high incidence 'suicide clusters' were occurring. Such clusters represent candidate regions where intervention is critically needed, and likely to have the greatest impact, thus providing an evidence-base for the targeted prioritisation of resources.

METHODS

Analysis is based on official suicide mortality statistics for NSW, provided by the Australian Bureau of Statistics, and hospital separations for non-fatal intentional self-harm, provided through the NSW Health Admitted Patient Data Collection at a Statistical Area 2 (SA2) geography. Geographical Information System (GIS) techniques were applied to detect suicide clusters occurring between 2005 and 2013 (aggregated), for persons aged over 5 years. The final dataset contained 5466 mortality and 86,017 non-fatal intentional self-harm cases.

RESULTS

In total, 25 Local Government Areas were identified as primary or secondary likely candidate regions for intervention. Together, these regions contained approximately 200 SA2 level suicide clusters, which represented 46% (n = 39,869) of hospital separations and 43% (n = 2330) of suicide deaths between 2005 and 2013. These clusters primarily converged on the Eastern coastal fringe of NSW.

CONCLUSIONS

Crude rates of suicide deaths and intentional self-harm differed at the Local Government Areas (LGA) level in NSW. There was a tendency for primary suicide clusters to occur within metropolitan and coastal regions, rather than rural areas. The findings demonstrate the importance of taking geographical variation of suicidal behaviour into account, prior to development and implementation of prevention initiatives, so that such initiatives can target key problem areas where they are likely to have maximal impact.

Exposure to suicidal behaviors: A common suicide risk factor or a personal negative life event?

BACKGROUND

Numerous suicide risk factors have been proposed but not adequately validated for epidemiology, treatment and prevention efforts.

AIMS

Exposures to suicidal behaviors (ESB), from family and friend suicide attempts and completions, were tested for validity as a suicidal risk factor and also for measurement and construct adequacy.

METHODS

An anonymous online survey yielded 713 participants (aged 18-71), who reported ESB, completed the Suicidal Affect-Behavior-Cognition Scale (SABCS), and comprised a broad spectrum on those variables.

RESULTS

Tests of dimensionality and internal consistency showed the four ESB variables (attempts/completions through family/friends) were independent and did not form a common factor or an identifiable ESB latent trait. ESB variables were, however, associated with demographic and psychiatric histories. A battery of tests revealed no meaningful associations between ESB and total suicidality or suicide risk factors (social support, depression, anxiety, stress, satisfaction with life and emotional stability). In addition, in contrast to previous reports, young adults ( n = 200; aged 18-20) showed no increased suicidality due to ESB.

CONCLUSION

Results showed no validity for ESB as a common risk factor for suicidality or other psychopathology, or as a latent trait. ESB showed evidence as a personal negative life event with individual effects and interpretations.

Research protocol for a digital intervention to reduce stigma among males with a personal experience of suicide in the Australian farming community

Background

Australian farming communities have up to twice the suicide rate of the general population. Men, particularly, demonstrate debilitating self- and perceived-stigma associated with an experience of suicide. The Ripple Effect is aimed to reduce suicide stigma within the social, cultural, geographical and psychological contexts in which it occurs.

Methods

A mixed-method design with multi-level evaluation will be effected following the development and delivery of a personalised website experience (combining shared stories, education, personal goal setting and links to resources) to farming men, aged 30–64 years, with an experience of suicide. Pre- and post-surveys will be used to assess changes in self- and perceived-stigma and suicide literacy. Online feedback from participants and semi-structured interviews during follow-up will be thematically analysed.

Discussion

This project will provide information about increasingly accessible, innovative approaches to reducing the debilitating health and wellbeing effects of suicide stigma on a population of Australia’s farmers.

Trial registration

This research protocol was registered with the Australian New Zealand Clinical Trials Registry (ANZCTR) (ACTRN: ACTRN12616000289415) on 7^th March, 2016.

Changes in South Korean urbanicity and suicide rates, 1992 to 2012

OBJECTIVES

Studies have highlighted the association between the degree of urbanicity and spatial disparities in suicide, but few have evaluated its changes across time. We explored the geospatial trends of suicide in South Korea from 1992 to 2012, and their relationship to the nation's evolving urbanicity.

SETTING

South Korea.

PRIMARY OUTCOME MEASURES

Age-sex-specific suicide rate.

RESULTS

Suicide rates increased in all regions of South Korea during the study period. Controlling the effects of age and sex, there was an overall inverse relationship between the degree of urbanicity and regional suicide rates. These associations were, however, attenuated across the periods, as there were smaller increases in suicide rates in mid-sized urban regions as compared to larger cities and to rural areas. Increases over time in the suicide rates among youth and working-age adults were greater in large urban centres and in rural regions. For elders, the increase was far greater in rural regions.

CONCLUSIONS

The association of urbanicity and the geospatial pattern of suicide in South Korea was a dynamic process and varied by age groups across the course of two decades. Internal migration and related social processes most likely contributed to these changes.

Men's Sheds and the experience of depression in older Australian men

BACKGROUND/AIM

Men's Sheds are community spaces where, usually, older men can socialise as they participate in a range of woodwork and other activities. There is currently little research evidence supporting the anecdotally reported mental health and wellbeing benefits of Men's Sheds. This research project investigated how older men with self-reported symptoms of depression experience their participation in Men's Sheds.

METHODS

This study included in-depth interviews and administration of the Beck Depression Inventory-II with 12 men from 3 Men's Sheds, triangulated with observation of the different shed environments. Interviews explored how participation in the Men's Shed, living in a regional area, and retirement intersected with experiences of depression. Participants had either self-reported symptoms of depression or a diagnosis of depression.

RESULTS

The findings from this study support the notion that participation at Men's Sheds decreases self-reported symptoms of depression. Beck Depression Inventory-II scores showed that most participants were currently experiencing minimal depression. The Men's Sheds environment promoted a sense of purpose through relationships and in the sharing of skills, new routines, motivation, and enjoyment for its members. The shed encouraged increased physical activity and use of cognitive skills. Finally, participants reported feelings of pride and achievement which had an impact on their sense of self-worth.

CONCLUSION

Men's Sheds provide an opportunity to promote health and wellbeing among retired men. The shed's activity and social focus offers a way to help men rediscover purpose and self. Further research is required to measure symptoms of depression before and after participation in Men's Sheds.

Self-reported contacts for mental health problems by rural residents: predicted service needs, facilitators and barriers

BACKGROUND

Rural and remote Australians face a range of barriers to mental health care, potentially limiting the extent to which current services and support networks may provide assistance. This paper examines self-reported mental health problems and contacts during the last 12 months, and explores cross-sectional associations between potential facilitators/barriers and professional and non-professional help-seeking, while taking into account expected associations with socio-demographic and health-related factors.

METHODS

During the 3-year follow-up of the Australian Rural Mental Health Study (ARMHS) a self-report survey was completed by adult rural residents (N = 1,231; 61% female; 77% married; 22% remote location; mean age = 59 years), which examined socio-demographic characteristics, current health status factors, predicted service needs, self-reported professional and non-professional contacts for mental health problems in the last 12 months, other aspects of help-seeking, and perceived barriers.

RESULTS

Professional contacts for mental health problems were reported by 18% of the sample (including 14% reporting General Practitioner contacts), while non-professional contacts were reported by 16% (including 14% reporting discussions with family/friends). Perceived barriers to health care fell under the domains of structural (e.g., costs, distance), attitudinal (e.g., stigma concerns, confidentiality), and time commitments. Participants with 12-month mental health problems who reported their needs as met had the highest levels of service use. Hierarchical logistic regressions revealed a dose-response relationship between the level of predicted need and the likelihood of reporting professional and non-professional contacts, together with associations with socio-demographic characteristics (e.g., gender, relationships, and financial circumstances), suicidal ideation, and attitudinal factors, but not geographical remoteness.

CONCLUSIONS

Rates of self-reported mental health problems were consistent with baseline findings, including higher rural contact rates with General Practitioners. Structural barriers displayed mixed associations with help-seeking, while attitudinal barriers were consistently associated with lower service contacts. Developing appropriate interventions that address perceptions of mental illness and attitudes towards help-seeking is likely to be vital in optimising treatment access and mental health outcomes in rural areas.

Suicides in Urban and Rural Counties in the United States, 2006–2008

Background: Suicide rates are higher in rural areas. It has been hypothesized that inadequate access to care may play a role, but studies examining individual decedent characteristics are lacking. Aims: We sought to characterize the demographic, socioeconomic, and mental health features of individual suicide decedents by urban–rural residence status. Method: We analyzed suicides in 16 states using 2006–2008 data from the National Violent Death Reporting System and examined associations between decedent residence type and suicide variables with separate logistic regressions adjusted for age, sex, race, and ethnicity. Results: Of 17,504 analyzed suicides, 78% were in urban, 15% in rural adjacent, and 8% in rural nonadjacent locations. Rural decedents were less likely than urban decedents to have a mental health diagnosis or mental health care, although the prevalence of depressed moods appeared similar. Most suicides were by firearm, and rural decedents were more likely than urban decedents to have used a firearm. Conclusion: Rural decedents were less likely to be receiving mental health care and more likely to use firearms to commit suicide. A better understanding of geographic patterns of suicide may aid prevention efforts.

Longitudinal course and predictors of suicidal ideation in a rural community sample

OBJECTIVE

Suicide rates in rural Australia are higher than in urban areas. No existing research has explored the long-term patterns and predictors of change in suicidal ideation within rural areas. This report uses longitudinal data and multiple time points to determine predictors of the trajectory of suicidal ideation in rural Australia.

METHOD

Participants in the Australian Rural Mental Health Study (ARMHS) completed self-report surveys at baseline, 12 and 36 months, reporting their psychological and social well-being, and suicidal ideation. Generalised linear mixed models explored these factors as correlates and predictors of suicidal ideation across 3 years using multiple data points.

RESULTS

A total of 2135 participants completed at least one wave of ARMHS, and hence were included in the current analysis. Overall, 8.1% reported suicidal ideation during at least one study wave, 76% of whom reported suicidal ideation intermittently rather than consistently across waves. Across the three time points, suicidal ideation was significantly associated with higher psychological distress (OR 1.30, 95% CI 1.23 to 1.37), neuroticism (OR 1.15, 95% CI 1.04 to 1.27), and availability of support (OR 0.80, 95% CI 0.69 to 0.92), with a non-significant association with unemployment (OR 1.73, 95% CI 0.93 to 3.24) even after controlling for the effects of perceived financial hardship. Future suicidal ideation was significantly predicted by distress (OR 1.16, 95% CI 1.09 to 1.23) and neuroticism (OR 1.17, 95% CI 1.03 to 1.32), with a non-significant association with unemployment (OR 2.11, 95% CI 0.41 to 2.27). Predictive effects for marital status, social networks, sense of community and availability of support did not remain significant in the full multivariate analysis.

CONCLUSIONS

Fluctuations in suicidal ideation are common, and may be associated with changes in psychological and social well-being. Public health strategies, focusing on encouraging help-seeking among those with higher psychological distress, lower social support, and unstable or absent employment opportunities, may be a useful long-term initiative to reduce the prevalence of suicidal ideation in the general rural community.

Alcohol consumption, obesity, and psychological distress in farming communities-an Australian study

PURPOSE

Alcohol consumption patterns nationally and internationally have been identified as elevated in rural and remote populations. In the general Australian population, 20.5% of adult males and 16.9% of adult females drink at short-term, high-risk levels. Farmers are more likely to drink excessively than those living in major cities. This study seeks to explore the relationships between farmers' physical and mental health and their alcohol consumption patterns. Our hypothesis is that farmers consume alcohol at high-risk levels more often than the Australian average and that this consumption is associated with obesity and psychological distress.

METHODS

Cross-sectional descriptive data were collected within Australian farming communities from 1,792 consenting adults in 97 locations across Australia. Data on anthropometric measurements, general physical attributes and biochemical assessments were used to explore the interrelationships of self-reported alcohol consumption patterns with obesity, psychological distress, and other physical health parameters.

FINDINGS

There was a higher prevalence of short-term, high-risk alcohol consumption (56.9% in men and 27.5% in women) reported in the study compared with national data. There was also a significant positive association between the prevalence of high-risk alcohol consumption and the prevalence of obesity and abdominal adiposity in psychologically distressed participants.

CONCLUSIONS

The prevalence of short-term, high-risk alcohol consumption practices in this cohort of farming men and women is significantly higher than the Australian average. These consumption practices are coupled with a range of other measurable health issues within the farming population, such as obesity, hypertension, psychological distress, and age.

You've got to have friends: the predictive value of social integration and support in suicidal ideation among rural communities

PURPOSE

To explore the role of social integration and support in the longitudinal course of suicidal ideation (SI) in a rural population.

METHODS

Baseline and 12-month data were obtained from participants within the Australian Rural Mental Health Study, a longitudinal study of community residents within rural and remote New South Wales, Australia. SI was assessed using the Patient Health Questionnaire. Individual psychological factors, family and community characteristics were examined alongside personal social networks (Berkman Syme Social Network Index), availability of social support (Interview Schedule for Social Interaction) and perception of local community (Sense of Community Index).

RESULTS

Thirteen hundred and fifty-six participants were included in the analysis (39% male, mean age 56.5 years). Sixty-one participants reported recent SI at baseline, while 57 reported SI at follow-up. Baseline SI was a strong predictor of SI at 12 months [odds ratio (OR) 19.0, 95% confidence interval (CI) 8.6-42.3); significant effects were also observed for baseline values of psychological distress (OR 1.4, 95% CI 1.0-1.9) and availability of social support (OR 0.76, 95% 0.58-1.0) on 12-month SI. The emergence of SI at 12-month follow-up was predicted by higher psychological distress (OR 1.8, 95% CI 1.3-2.4); there was a marginal effect of lower availability of support (OR 0.74, 95% CI 0.55-1.0); neither of these variables predicted SI resolution.

CONCLUSIONS

This study investigated factors associated with SI over a 12-month period in a rural cohort. After controlling for known risk factors for SI, low availability of social support at baseline was associated with greater likelihood of SI at 12-month follow-up.

Suicide in young men

Suicide is second to only accidental death as the leading cause of mortality in young men across the world. Although suicide rates for young men have fallen in some high-income and middle-income countries since the 1990s, wider mortality measures indicate that rates remain high in specific regions, ethnic groups, and socioeconomic groups within those nations where rates have fallen, and that young men account for a substantial proportion of the economic cost of suicide. High-lethality methods of suicide are preferred by young men: hanging and firearms in high-income countries, pesticide poisoning in the Indian subcontinent, and charcoal-burning in east Asia. Risk factors for young men include psychiatric illness, substance misuse, lower socioeconomic status, rural residence, and single marital status. Population-level factors include unemployment, social deprivation, and media reporting of suicide. Few interventions to reduce suicides in young men have been assessed. Efforts to change help-seeking behaviour and to restrict access to frequently used methods hold the most promise.

Spatial analysis of suicide mortality in Australia: investigation of metropolitan-rural-remote differentials of suicide risk across states/territories

Studies of suicide epidemiology in regions of Australia have been conducted, but the spatial pattern in the whole country has not been fully investigated. This study aimed at visualizing the sex-specific suicide pattern over the country from 2004 to 2008, and studying the metropolitan-rural-remote differentials of suicide across all states/territories. We applied a Poisson hierarchical model to yield smoothed sex specific, age standardized mortality ratios of suicide in all postal areas, and compiled the age-standardized suicide rates across different levels of remoteness and different jurisdictions. We identified the area variation of suicide risk across states/territories, and metropolitan-rural-remote differential with rates higher in rural and remote areas for males. Spatial clusters of some high risk postal areas were also identified. Socio-economic deprivation, compositional factors, high risks for Indigenous people and low access to mental health service are the underlying explanations of the elevation of suicide risk in some areas. These findings suggest that it is important to take geographical variations in suicide risk into account in national policy making. Particular suicide prevention interventions might be targeted at males living in remote areas, and some localized areas in metropolitan zones.

Urban-rural influences on suicidality: gaps in the existing literature and recommendations for future research

Suicide is a major public health issue of particular concern among rural populations, which experience a consistently higher suicide rate than urban areas. Although extensive research efforts have been directed towards understanding suicidality and related factors, there is a continued lack of clinically useful factors to target preventive measures, particularly among some regional and demographic groups. This suggests limitations in the conceptualisation of this important construct. A review of the literature was undertaken, using a snowballing and saturation approach. Literature was considered relevant if it addressed the research question 'what are the current limitations in research on urban/rural influences on suicidality?' Findings were used to develop a set of guidelines to inform future research. A number of gaps in existing research relevant to limitations in rural suicide research were identified: inconsistencies in terminology; a focus on high-end suicidal behaviours; a disproportionate focus on urban populations; a dominance of cross-sectional research; and a high use of clinical samples. These limitations are discussed in terms of their implications for rural suicidality, and are used to support the development of recommendations for future research, with a focus on encouraging consistency and standardisation. A number of limitations can be identified in existing research on suicide. Targeting these specific areas can be an important step in addressing the current gaps in knowledge relating to rural suicide prevention.

Using cohort studies to investigate rural and remote mental health

This paper, presented at the 2010 rural health researchers' National Scientific Symposium on Rural and Remote Health, provides an overview of large Australian population mental health cohort studies which have a focus on climate-related and environmental adversity, social factors and mental health. These studies highlight the value of exploiting multiple exceptional datasets to better understand the drivers of rural health, including how to use population-level research to improve health resources in non-metropolitan areas. We show how the key characteristics of rural and remote mental health might be explored by exploiting the following cohort studies: Household, Income and Labour Dynamics in Australia Survey; Australian Rural Mental Health Study; Hunter Community Study; and Extending Treatments, Education and Networks in Depression study. Existing cohort studies that focus on significant rural and regional characteristics can be creatively analysed to better understand geographic variation in mental health. They have the potential to move understanding beyond simple prevalence to building knowledge about the trajectories of psychological distress and determinants of mental disorders and outcomes over time.

Determinants of mental health and well-being within rural and remote communities

BACKGROUND

The individual and contextual factors influencing current mental health and well-being within rural communities are poorly understood.

METHODS

A stratified random sample of adults was drawn from non-metropolitan regions of NSW, Australia. One-quarter (27.7%) of the 2,639 respondents were from remote/very remote regions. An aggregate measure of current well-being was derived from levels of distress and related impairment (Kessler-10 LM), self-reported overall physical and mental health, functioning, satisfaction with relationships, and satisfaction with life. Multivariate methods investigated the contributions to current well-being of demographic/dispositional factors, recent events and social support, individual exposure to rural adversity, and district/neighbourhood level characteristics.

RESULTS

Respondents from very remote regions tended to be younger and have lower education. Univariate associations were detected between well being and exposure to rural adversity (greater drought-related worry, lower perceived service and support availability, greater number of years living in the current district). Multivariate analysis (n = 2,462) accounted for 41% of the variance in well-being scores. The major contributing variables were dispositional factors (trait neuroticism, marital status), recent adverse events and indices of social support. However, no additional effects were detected for district-level variables (drought severity, regional socioeconomic categorisation, population change). Similar associations were detected using the K-10 alone as the outcome measure.

CONCLUSIONS

The chief determinants of current well being were those reflecting individual level attributes and perceptions, rather than district-level rural characteristics. This has implications for strategies to promote well being within rural communities through enhancing community connectedness and combating social isolation in the face of major adversities such as drought.

Effectiveness of Australian youth suicide prevention initiatives

BACKGROUND

After an epidemic rise in Australian young male suicide rates over the 1970s to 1990s, the period following the implementation of the original National Youth Suicide Prevention Strategy (NYSPS) in 1995 saw substantial declines in suicide in young men.

AIMS

To investigate whether areas with locally targeted suicide prevention activity implemented after 1995 experienced lower rates of young adult suicide, compared with areas without such activity.

METHOD

Localities with or without identified suicide prevention activity were compared during the period of the NYSPS implementation (1995-1998) and a period subsequent to implementation (1999-2002) to establish whether annual average suicide rates were lower and declined more quickly in areas with suicide prevention activity over the period 1995-2002.

RESULTS

Male suicide rates were lower in areas with targeted suicide prevention activity (and higher levels of funding) compared with areas receiving no activity both during (RR = 0.89, 95% CI 0.80-0.99, P = 0.030) and after (RR = 0.86, 95% CI 0.77-0.96, P = 0.009) implementation, with rates declining faster in areas with targeted activity than in those without (13% v. 10% decline). However, these differences were reduced and were no longer statistically significant following adjustment for sociodemographic variables. There was no difference in female suicide rates between areas with or without targeted suicide prevention activity.

CONCLUSIONS

There was little discernible impact on suicide rates in areas receiving locally targeted suicide prevention activities in the period following the NYSPS.

Reducing psychological distress and obesity in Australian farmers by promoting physical activity

BACKGROUND

Studies have confirmed that the rate of mental illness is no higher in rural Australians than that of urban Australians. However, the rate of poor mental health outcomes, and in particular suicide, is significantly raised in rural populations. This is thought to be due to lack of early diagnosis, health service access, the distance-decay effect, poor physical health determinants and access to firearms. Research conducted by the National Centre for Farmer Health between 2004 and 2009 reveals that there is a correlation between obesity and psychological distress among the farming community where suicide rates are recognised as high. Chronic stress overstimulates the regulation of the hypothalamic-pituitary-adrenal (HPA) axis that is associated with abdominal obesity. Increasing physical activity may block negative thoughts, increase social contact, positively influence brain chemistry and improve both physical and mental health. This paper describes the design of the Farming Fit study that aims to identify the effect of physical activity on psychological distress, obesity and health behaviours such as diet patterns and smoking in farm men and women.

METHODS/DESIGN

For this quasi-experimental (convenience sample) control-intervention study, overweight (Body Mass Index ≥25 kg/m(2)) farm men and women will be recruited from Sustainable Farm Families™ (SFF) programs held across Victoria, Australia. Baseline demographic data, health data, depression anxiety stress scale (DASS) scores, dietary information, physical activity data, anthropometric data, blood pressure and biochemical analysis of plasma and salivary cortisol levels will be collected. The intervention group will receive an exercise program and regular phone coaching in order to increase their physical activity. Analysis will evaluate the impact of the intervention by longitudinal data (baseline and post intervention) comparison of intervention and control groups.

DISCUSSION

This study is designed to examine the effect of physical activity on psychological health and other co-morbidities such as obesity, impaired glucose tolerance, hypertension and dyslipidaemia within a high-risk cohort. The outcomes of this research will be relevant to further research and service delivery programs, in particular those tailored to rural communities.

The acceptability of suicide among rural residents, urban residents, and college students from three locations in China: a cross-sectional survey

BACKGROUND

Community attitudes about suicide and their relationship to suicidal behavior have not been adequately investigated in low- and middle-income countries.

AIMS

To compare the acceptability of suicide in different population cohorts in China, identify factors that affect the degree of acceptability, and assess the relationship of cohort-specific acceptability of suicide and suicide rates.

METHODS

A multistage stratified random sample of 608 rural residents, 582 urban residents, and 629 college students were administered a 25-item scale studying the likelihood they would consider suicide (on a 5-point Likert scale) if they experienced a variety of stressors ranging from "being disciplined at work" to "developing a chronic mental illness." The internal consistency and test-retest reliability for the scale are excellent (Cronbach's alpha = 0.92, ICC = 0.75).

RESULTS

College students had the most permissive attitudes about suicide, and urban residents were significantly more accepting of suicide as a response to serious life stressors than were rural residents. Multivariate analysis found that the overall acceptability score was higher in women, decreased with age, and increased with years of education.

CONCLUSIONS

There was no clear relationship between cohort-specific acceptance of suicide and reported rates of suicide, highlighting the complexity of the relationship between attitudes about suicide (of which acceptability is only one component) and suicidal behavior.

Spatial distribution of suicide in Queensland, Australia

BACKGROUND

There has been a lack of investigation into the spatial distribution and clustering of suicide in Australia, where the population density is lower than many countries and varies dramatically among urban, rural and remote areas. This study aims to examine the spatial distribution of suicide at a Local Governmental Area (LGA) level and identify the LGAs with a high relative risk of suicide in Queensland, Australia, using geographical information system (GIS) techniques.

METHODS

Data on suicide and demographic variables in each LGA between 1999 and 2003 were acquired from the Australian Bureau of Statistics. An age standardised mortality (ASM) rate for suicide was calculated at the LGA level. GIS techniques were used to examine the geographical difference of suicide across different areas.

RESULTS

Far north and north-eastern Queensland (i.e., Cook and Mornington Shires) had the highest suicide incidence in both genders, while the south-western areas (i.e., Barcoo and Bauhinia Shires) had the lowest incidence in both genders. In different age groups (≤ 24 years, 25 to 44 years, 45 to 64 years, and ≥ 65 years), ASM rates of suicide varied with gender at the LGA level. Mornington and six other LGAs with low socioeconomic status in the upper Southeast had significant spatial clusters of high suicide risk.

CONCLUSIONS

There was a notable difference in ASM rates of suicide at the LGA level in Queensland. Some LGAs had significant spatial clusters of high suicide risk. The determinants of the geographical difference of suicide should be addressed in future research.

Rural-urban differences in suicide rates for current patients of a public mental health service in Australia

Rural versus urban rates of suicide in current patients of a large area mental health service in Australia were compared. Suicide deaths were identified from compulsory root cause analyses of deaths, 2003-2007. Age-standardized rates of suicide were calculated for rural versus urban mental health service and compared using variance of age-standardized rates with 95% confidence intervals. There were 44 suicides and the majority (62%) were rural. Only urban patients used jumping from heights as a method of suicide (4/17; p = 0.02). Rural patients had 2.7 times higher rates of suicide, similar to findings for rural versus urban community suicides and may reflect the underlying community rates, differences in mental health service delivery, or socioeconomic disadvantage.

Mental disorders and socioeconomic status: impact on population risk of attempted suicide in australia

The population attributable risk (PAR) of mental disorders compared to indicators of socioeconomic status (SES) for attempted suicide was estimated for Australia. For mental disorders, the highest PAR% for attempted suicide was for anxiety disorders (males 28%; females 36%). For SES, the highest PAR% for attempted suicide in males was for occupation (males 31%; females 16%) and education level (males 19%; females 8%), following adjustment for age and mental disorders. The study results suggest that one third of suicide attempts in both males and females are attributable to anxiety disorders, the same proportion attributable to low educational or occupational status.

Sociodemographic correlates of antidepressant utilisation in Australia

OBJECTIVE

To investigate sociodemographic variation in antidepressant utilisation.

DESIGN AND SETTING

Cross-sectional analysis of antidepressant prescription under the Pharmaceutical Benefits Scheme in Australia, 2003-2005.

MAIN OUTCOME MEASURES

Antidepressant utilisation (defined daily dose/1000/day) by sex, age, socioeconomic status (SES) and geographical area.

RESULTS

Total antidepressant utilisation increased with age. Among those aged > or = 15 years, female utilisation was about double that of males. About half of antidepressant utilisation was accounted for by sertraline, venlafaxine, citalopram, and paroxetine. SES differentials in antidepressant utilisation changed across age groups for males and females: among those aged < or = 19 years, total antidepressant utilisation was significantly less in lower SES groups (P < 0.001); there was no relationship to SES among 20-29-year-olds; and among those aged > or = 30 years, antidepressant utilisation was significantly higher in lower SES groups (P < 0.001). SES differences were attenuated after adjusting for urban or rural residence, but remained statistically significant. Antidepressant utilisation rates were highest in regional centres.

CONCLUSION

Antidepressant utilisation in Australia partially reflects sociodemographic differences in the prevalence of affective disorder. Discrepancies between treatment provision and treatment need suggest that not all social strata in Australia have equal access to these treatments.

Suicides on farms in South Australia, 1997-2001

OBJECTIVE

Despite much having been written, both nationally and internationally, about rural suicides, no one in Australia knows either the number of residents on farms or the suicide rate for this group of people. This paper seeks to determine the number of residents on farms in South Australia, along with the suicide rate.

DESIGN, SETTING AND PARTICIPANTS

A retrospective audit review of the files of suicides completed between the 1 January 1997 and 31 December 2001 was undertaken in the South Australian Coroner's Office. There were 1033 cases examined for sociodemographic details and 380 files were explored in detail.

RESULTS

Estimating both the number of agricultural establishments in South Australia and the resident population on farms for 2001, and determining the number of suicides on farms between 1997 and 2001, the farm suicide rate was found to be 33.8 for men, 6.7 for women and 21.6 per 100,000 for persons, much higher than the rural suicide rate for South Australia in 2001 (23.8 for men, 5.6 for women and 14.5 per 100,000 for persons) according to the Australian Bureau of Statistics.

CONCLUSIONS

This study provides an estimate of the number of farm residents in South Australia in 2001, the number and rate of suicides on farms in South Australia in 2001, and shows that this rate is significantly higher than the overall rate of suicide in South Australia in 2001.

The impact of rural residence on medically serious medicinal self-poisonings

OBJECTIVE

Suicide rates are often high in rural areas. Despite the strong association between deliberate self-harm (DSH) and suicide, few have studied rural residence and DSH. Self-poisonings dominate DSH hospital presentations. We investigate a previously reported association between rural residence and medical severity (defined as a subsequent medical/surgical inpatient stay) among emergency department presentations for medicinal self-poisoning (SP) to determine whether differences in agents taken, mental health service use or hospital-level resources explain the relationship.

METHOD

A cohort of n=16,294 12-64-year olds presenting with SP to hospital emergency departments in Ontario, Canada, in 2001/2002 was linked to their service records over time.

RESULTS

The rural-medical severity association was best explained by differences in hospital resources; presenting to hospitals providing inpatient psychiatric services appeared to reduce medical/surgical inpatient stays in favor of psychiatric ones. Among those with a recent psychiatric admission, more intensive ambulatory psychiatric contact may be protective of a psychiatric inpatient stay subsequent to the SP presentation. Compared to nonrural residents, deliberate intent was identified less often in rural residents, particularly males.

CONCLUSIONS

The rural-medical severity association was best explained by disparities in the delivery systems serving rural and nonrural residents, important to rural suicide prevention efforts.

Rural-urban differences in Austrian suicides

OBJECTIVES

The answer to the question whether suicide rates are higher in urban than in rural areas may have changed over the years. This study analyzes the longitudinal trends of rural and urban suicides in Austria from 1970 to 2005. The most recent decade, 1995-2005 was also investigated cross-sectionally in terms of age groups, gender, suicide methods and family status.

METHODS

Official suicide statistics were calculated in a Poisson regression model to determine trends in suicide rates according to gender in rural and urban regions as well as the ratios of rural- to urban-suicide rates. Population density levels were used as a measure of urbanization. Differences in suicide rates across the rural-urban categories were investigated in terms of genders, age groups, suicide methods and family status using Spearman correlations.

RESULTS

The ratio of rural to urban suicide rates has continuously increased in both genders over the past 35 years, indicating a growing risk in rural areas. Suicide methods used in rural and urban areas vary significantly and suicide rates among men, but not women, were found to decrease with increasing urbanicity.

CONCLUSION

In line with recent findings from other western countries, we showed a growing gap between rural and urban suicide rates. This suggests a need for rural-specific suicide prevention efforts, especially aimed at the male rural population.

Lifetime prevalence of suicide ideation, plan, and attempt in metropolitan China

OBJECTIVE

This is the first community-based epidemiological study examining the prevalence of suicidal behaviors, their transitional pathways, and their relationship with mental disorders in metropolitan China.

METHOD

Suicidal behaviors, including ideation, plans, and attempts were assessed by face-to-face household interviews among 5201 respondents in Beijing and Shanghai in 2001-2002. Lifetime prevalence and risk factors were examined using multivariate discrete-time survival models.

RESULTS

The lifetime prevalence estimates of suicidal ideation, plans, and attempts were 3.1%, 0.9%, and 1.0% respectively. Among suicide ideators, the conditional probability of ever making a plan and an attempt was 29.5% and 32.3% respectively. Progression from ideation to plan and attempt was the highest during the first year after onset. Suicide attempt was predicted by young adulthood, being unmarried, recent onset of ideation and plan, and the presence of mental disorders, especially mood disorder.

CONCLUSION

Suicidal behaviors in metropolitan China exhibit a low prevalence and an epidemiological profile resembling that found in Western countries.

Further increases in rural suicide in young Australian adults: Secular trends, 1979–2003

This study investigates changes in Australian urban-rural suicide differentials over time in the context of overall declines in (male) suicide in the late 1990s, and determines the extent to which differences in socio-economic status (SES) account for observed urban-rural trends. Suicide data were stratified for the period 1979-2003 by metropolitan, rural and remote areas and examined across five quinquennia, centred on each Australian census from 1981 to 2001. Suicide rates (per 100,000) were adjusted for confounding by sex, age, country-of-birth and the mediating effects of area SES, using Poisson regression models. Male suicide rates in metropolitan, rural and remote areas diverged significantly over time, especially in young males (15-24 years). Young male suicide rates increased significantly in metropolitan, rural and remote areas over 1979-1998, and in the most recent period (1999-2003) increased further in remote areas from 38.8 (per 100,000) to 47.9 (23% increase). In contrast suicide rates in rural areas decreased from a peak of 27.5 to 19.8 (28% decrease), and in metropolitan areas from a peak of 22.1 to 16.8 (24% decrease). Similar divergence in the 1999-2003 quinquennium, though of a lesser magnitude, was also evident for males aged 25-34 years. Female suicide rates in the earlier part of the period were significantly lower in rural and remote areas than in metropolitan areas, particularly for those aged 25-34 years, then increased in rural and remote areas to converge with female suicide rates in metropolitan areas. Adjusting for SES in addition to age and country-of-birth reduced urban-rural suicide differentials in both males and females, consistent with SES being an intermediary between rural residence and suicide. Nevertheless, urban-rural differences remained statistically significant. These results show that the largest urban-rural male suicide differentials for the 25-year study period occurred in the most recent period (1999-2003), in the context of decreasing male suicide rates overall.

A review of the literature on rural suicide: risk and protective factors, incidence, and prevention

BACKGROUND

Suicide is a major cause of mortality worldwide. Differences in rates of suicide exist between urban and rural areas; however, little rigorous research has examined the phenomena of rural suicide.

OBJECTIVE

This review examines the current body of literature on rural suicide and investigates differences between rural and urban suicide, including socioeconomic, psychological, and cultural variables. Prevention and intervention strategies specific to rural communities are discussed. DESCRIPTION OF STUDIES: All empirical and epidemiological studies of rural suicide were included in the review regardless of study design or methodology.

RESULTS

Although findings are mixed, research and epidemiological data indicate that suicide is a public health concern in rural areas, with suicide rates often greater than in urban areas.

DISCUSSION

Rural locale may create geographic, psychological, and sociocultural barriers to treatment of suicide. A better understanding of the role of rurality in the development and maintenance of suicidal thoughts and behaviors is needed and may inform prevention and intervention efforts.

Emergency management guidelines for telepsychiatry

OBJECTIVE

Telepsychiatry, in the form of live interactive videoconferencing, is an emerging application for emergency psychiatric assessment and treatment and can improve the quality and quantity of mental health services, particularly for rural, remote and isolated populations. Despite the potential of emergency telepsychiatry, the literature has been fairly limited in this area.

METHOD

Drawing on the combined clinical and administrative experiences of its authors, this article reviews the common administrative, legal/ethical and clinical issues that arise in emergency telepsychiatry.

RESULTS

An initial set of guidelines for emergency telepsychiatry is presented to generate further discussion to assist those who are considering establishing general telepsychiatry and/or emergency telepsychiatry services.

CONCLUSION

The practices and techniques of emergency telepsychiatry are relatively new and require further examination, modification and refinement so that they may be fully utilized within comprehensive mental health service systems.

Divergent trends in suicide by socio-economic status in Australia

OBJECTIVES

This study investigated secular trends in socio-economic status (SES) differentials in Australian suicide (1979-2003), which includes overall declines in male suicide from 1998.

METHOD

Suicide rates were stratified by approximate equal-population quintiles of area-based SES for the period 1979-2003 and examined across five quinquennia, centred on each Australian Census from 1981 to 2001, to determine if (1) SES differentials in suicide have persisted over time, and (2) if SES differentials have widened or narrowed. Suicide rates (per 100,000) were adjusted for confounding by sex, age, country-of-birth, and urban-rural residence using Poisson regression models, and secular changes in SES differentials were assessed using trend tests on suicide rate ratios (low to high SES quintiles).

RESULTS

Socio-economic status (SES) differentials persisted across the study period for both males and females after adjusting for the effects of age, migrant status, and urban-rural residence, with the largest differences between low and high SES groups evident in males, and especially young males (20-34 years). For males, suicide rates increased significantly in all SES groups until 1998, before diverging significantly in the most recent 5-year period, particularly in younger males (P<0.0001). In young males, suicide rates in the most recent period increased in the low SES group from 44.8 in 1994-1998 to 48.6 in 1999-2003 (an 8% increase). In contrast, suicide rates in the middle SES group decreased from a peak of 37.3 to 33.5 (a 10% decrease), and in the high SES group from a peak of 33.0 to 27.9 (a 15% decrease). A similar statistically significant divergence of a lesser magnitude was also evident in all age males and younger females (20-34 years).

CONCLUSION

This study shows that SES differentials in suicide persisted in Australia for most of the period 1979-2004. The decline in suicide in young males in the most recent quinquennium was limited to middle and high SES groups, while the low SES group displayed a continued increase. The continued increase in suicide in low SES males has implications for social and economic intervention and suicide control programs.

Hopelessness, demoralization and suicidal behaviour: the backdrop to welfare reform in Australia

OBJECTIVES

To estimate rates of suicidal ideation and attempts, and psychological characteristics of demoralization among Australian income support recipients. To provide information for policy-makers to inform the current welfare reform discussion.

METHOD

Data from the 1997 National Survey of Mental Health and Wellbeing were analysed using sequential logistic regression models, comparing working age people dependent on government income support payments with those having other main sources of income.

RESULTS

Three groups of income support recipients, unemployed, lone mothers and disability payment recipients, reported significantly higher levels on all psychological measures related to demoralization (hopelessness, worthlessness and dissatisfaction with life) than non-recipients. A similar pattern was demonstrated for measures of suicidal ideation and reported suicide attempts, with increased odds of between 3 and 9 for these high-risk groups of welfare recipients. The elevated rates of suicidal ideation, attempts and demoralization among income support recipients were in part explained by sociodemographic characteristics (socioeconomic status, age, educational qualification, experience of serious violence, loneliness, experience of psychiatric disorders), though the unemployed and disability payment recipients remained elevated on the psychological measures.

CONCLUSIONS

Demoralization, poor mental health and suicidal behaviour are common among income support recipients targeted by recently announced welfare reforms. This needs to be considered in the design and implementation of Australian Government policies. Psychiatric epidemiology has a key role in policy development and evaluation.

Rural habitat and risk of death in small areas of Southern Spain

The purpose of this paper is to study the linkage between type of habitat and mortality from all causes in small areas of Southern Spain. An ecological study was conducted on 99,870 people who died between 1985 and 1999. The municipality was taken as the unit of analysis. Data analysis was carried out through hierarchical spatio-temporal bayesian models. Results show a 13.3% reduction in mortality rates among men and 14.1% among women in the most rural areas compared to more urban environments. The study demonstrates the usefulness of socio-demographic indices in small-area geographical analyses.

Mental health and socio-economic variations in Australian suicide

This paper investigates the relationship between suicide rates and prevalence of mental disorder and suicide attempts, across socio-economic status (SES) groups based on area of residence. Australian suicide data (1996-1998) were analysed in conjunction with area-based prevalences of mental disorder derived from the National Survey of Mental Health and Well-Being (1997). Poisson regression models of suicide risk included age, quintile of area-based SES, urban-rural residence, and country of birth (COB), with males and females analysed separately. Analysis focussed on the association between suicide and prevalences of (ICD-10) affective disorders, anxiety disorders, substance use disorders and suicide attempts by SES group. Prevalences of other psychiatric symptomatology, substance use problems, health service utilisation, stressful life-events and personality were also investigated. Significant increasing gradients were evident from high to low SES groups for prevalences of affective disorders, anxiety disorders (females only), and substance use disorders (males only); sub-threshold drug and alcohol problems and depression; and suicide attempts and suicide (males only). Prevalences of mental disorder, other sub-threshold mental health items and suicide attempts were significantly associated with suicide, but in most cases associations were reduced in magnitude and became statistically non-significant after adjustment for COB, urban-rural residence, and SES. For male suicide the relative risk (RR) in the lowest SES group compared to the highest was 1.40 (95% CI 1.29-1.52, p<0.001) for all ages, and 1.46 (95% CI 1.27-1.67, p<0.001) for male youth (20-34 years). This relationship was not substantially modified in males when regression models included prevalences of affective disorders, and other selected mental health variables and demographic factors. From a population perspective, SES remained significantly associated with suicide after controlling for the prevalence of mental disorders and other psychiatric symptomatology. Mental conditions and previous suicidal behaviour may play an intermediary role between SES and suicide, but this study suggests that an independent relationship between suicide and SES also exists.
