Do macroeconomic contractions induce or 'harvest' suicides? A test of competing hypotheses

Do Changes in Employment Status Induce or "Harvest" Suicides?

In a seminal Swedish study, Gemmill and colleagues pursued whether suicides after economic contractions might reflect an "induction" process whereby economic change induces suicide in those otherwise unlikely to engage in self-destructive behavior, or a "displacement" process whereby economic contractions effectively bring forward suicides that would have occurred eventually, and found support for both hypotheses. We therefore undertook a replication study examining the hypotheses in the Australian state of New South Wales, analyzing suicide data for the same period as examined in Sweden (i.e., 2000-2011) and also over an extended period of 1978 to 2015. Our analyses failed to replicate findings from the Swedish study in that we found greater support for the induction hypothesis. Significant associations varied across sex and age groups. Our findings support the longstanding Durkheim hypothesis that suicide rates increase during times of low social integration and as a consequence of the economic changes acting as a precipitant stressor.

Work intensity in men and work-related emotional demands in women are associated with increased suicidality among persons attending primary care

BACKGROUND

A large proportion of persons died by suicide are employed at the time of death and work-related factors partly contribute to suicide risk. Our aim was to examine the association between multiple aspects of work organization and suicidal ideation in a study conducted in primary care.

METHODS

Data came from a study of 2027 working patients attending a GP representative of patients in the Nord Pas-de-Calais region in France (April-August 2014). Suicidality was assessed using the MINI (Mini International Neuropsychiatric Interview). Six emergent worked-related factors were explored (work intensity, emotional demands, autonomy, social relationships at work, conflict of values, insecurity of work). Several covariates were considered: patient's and GP's characteristics, and area-level data (material and social deprivation, psychiatrist and GPs' density, suicide attempts and suicide rates).

RESULTS

8.0% of participants reported suicidal ideation in the preceding month (7.5% of men and 8.6% of women, p = .03). In multivariate analyses adjusted for covariates, suicidality was significantly associated with work intensity (OR = 1.65; 95%CI [1.18-2.31]) in men and with work-related emotional demands (OR = 1.35; 95%CI [1.01-1.80]) in women. Area-level data were not associated.

LIMITATIONS

Our cross-sectional study cannot assess the direction of the relationships under study.

CONCLUSION

Our results emphasise a central role for GPs in suicide prevention among workers and highlight the importance of work-related factors with regard to suicidality in primary care.

Patterns of life expectancy before and during economic recession, 2003-12: a European regions panel approach

BACKGROUND

Previous research has reported a decrease in all-cause mortality during times of economic recession. Our objective was to identify the short-term effects of the current Great Recession on life expectancy at birth in Europe, and the role of social protection typology, income and gender.

METHODS

We used a pooled time series cross-sectional design, with 232 European regions (level 2 of the Nomenclature of Territorial Units for Statistics) as the unit of analysis over 10 years (2003-12). The dependent variable was life expectancy at birth, and the independent variable was unemployment rate. We fit a model in first differences for the periods before and during the Great Recession (2003-07 and 2008-12, respectively), and stratified by sex, social protection typology (Eastern, Mediterranean and Northern) and regional income per capita RESULTS: We observed a negative association during the Great Recession between life expectancy (in years) and in unit change in unemployment among men and women in low-income Mediterranean regions [-0.048(95%CI: -0.081,-0.014) and -0.050(95%CI:-0.091,-0.007), respectively] but no change in trend, and a change in trend to a non-significant negative association among men in high-income Mediterranean and Northern regions (P = 0.005 and P = 0.002, respectively). We also observed a positive association among men in middle-income Mediterranean regions [0.044 (95%CI:0.004,0.084)], with change in trend (P = 0.047), and Eastern regions [0.042 (95%CI:0.001,0.072)] without change in trend.

CONCLUSION

Overall, our data do not support the notion that increased life expectancy is associated with unemployment during the Great Recession.

Trends in suicidal behaviour in Dutch general practice 1983-2013: a retrospective observational study

OBJECTIVES

To analyse trends in suicidal behaviour as reported by the Dutch sentinel general practices from 1983 to 2013. Second, to examine the relationship between suicidal behaviour and several patient characteristics. Finally, to compare the relationship between suicidal behaviour and patient characteristics before (1983-2007) and after (2008-2013) the start of the crisis.

SETTING

40 general practices in the Netherlands during the period 1983-2013.

PARTICIPANTS

Patients with an ICPC code of P77 (suicide attempt).

PRIMARY AND SECONDARY OUTCOMES

Primary outcomes were age-adjusted and gender-specific trends in reported suicides (342) and suicide attempts (1614). Secondary outcomes were the relationship between suicidal behaviour and age, household composition, history of depression, recognition of suicide ideation, treatment before the suicidal behaviour and contact within the past month before suicidal behaviour for the period 1983-2013. Additionally, separate frequencies for the periods 1983-2007 and 2008-2013 were presented.

RESULTS

Join-point analyses revealed a significant rise in male suicides from 2008 (b=0.32, SE=0.1, p=0.008), and an increase in male suicide attempts since 2009 (b=0.19, SE=0.04, p<0.001). Female suicidal behaviour showed a steady decrease from 1989 to 2013(b=-0.03, SE=0.007, p<0.0001 for female suicide, b=-0.02, SE=0.002, p<0.001 for female attempts). Before 2007, a history of depression was reported in 65% (168/257) of the suicides. After the start of the recession, a depression was recognised in 44% (22/50) of the patients who died by suicide.

CONCLUSIONS

Since 2008, there was a rise in the male suicide rate while female suicide behaviour has continued to decline. General practitioners less often reported a history of depression within patients who died due to suicide after 2007 than before. Training in the early recognition of suicide ideation in depressive patients might improve suicide prevention in primary care.

Health Impacts of the Great Recession: A Critical Review

The severity, sudden onset, and multipronged nature of the Great Recession (2007-2009) provided a unique opportunity to examine the health impacts of macroeconomic downturn. We comprehensively review empirical literature examining the relationship between the Recession and mental and physical health outcomes in developed nations. Overall, studies reported detrimental impacts of the Recession on health, particularly mental health. Macro- and individual-level employment- and housing-related sequelae of the Recession were associated with declining fertility and self-rated health, and increasing morbidity, psychological distress, and suicide, although traffic fatalities and population-level alcohol consumption declined. Health impacts were stronger among men and racial/ethnic minorities. Importantly, strong social safety nets in some European countries appear to have buffered those populations from negative health effects. This literature, however, still faces multiple methodological challenges, and more time may be needed to observe the Recession's full health impact. We conclude with suggestions for future work in this field.

The World Health Organization (WHO) dataset for guiding suicide prevention policies: A 3-decade French national survey

BACKGROUND

Public health policies aim to prevent suicide in the general population. Assessing their effectiveness is required to further guide public health policies. The present article focuses on the French paradox. The French health care system was classified as the best in the world according the World Health Organization (WHO). However, suicide rates in France remain high compared to other European countries. The aim of the present article was to analyze (i) the evolution of suicide Age-Standardized Death (ASDRs) in France during the last three decades and the associations with socio-economic parameters and (ii) to understand which populations may specifically benefit from further targeted suicide prevention policies.

METHODS

The database of the World Health Organization (WHO), freely available, was explored in April 2015. ASDRs were calculated each year by ratio between the number of deaths by suicide and the total population (per 100,000 inhabitants). Number of deaths by gender and age were also analyzed.

RESULTS

Overall, ASDR suicide has decreased since 1987 in France (-32.8% between 1987 and 2010). However, France kept the same rank (10/26) when compared to other European countries between 1987 and 2010. The relative burden of suicide in all-causes mortality increased during the same period (+28.2%) while the total number of deaths by suicide increased only slightly (+3.9%). More specifically, the number of deaths by suicide increased substantially in [35-54] years old (+40%) and 75+ years old (+27%) males, and in [35-54] (+41%) years old females. Between 2000 and 2010, suicide rates significantly decreased when yearly mean income increased, and when general and psychiatric care beds decreased.

CONCLUSION

Although ASDR suicide has decreased in France since 1987, this decline is quite modest when considering its universal access to care, the prevention of depression and suicide public policies. Suicide prevention public policies should focus on evaluation and improvement of prevention and care in the [35-54] years old population, and in the males aged 75+.
