Trends in Suicide Mortality in Montenegro From 2000 to 2018

DOI: https://doi.org/10.21203/rs.3.rs-89461/v1

Abstract

Background: This is an ecological study that analyzes suicides committed in Montenegro during the 2000-2018 period, taking into account gender, age and methods of suicide.

Methods: Suicide rates and trends up until 2009 were obtained from the official registers of Bureau of Statistics of Montenegro (MONSTAT) while the later data were obtained from the Department of Interior’s. MONSTAT also provided data on unemployment and average salary. As per statistical methods, descriptive and correlations were calculated.

Results: The average crude suicide rate was 21.06, for males 29.93 and for females 12.42. Crude suicide rates were not associated with unemployment rate or average salary. However, the unemployment rate was significantly correlated with lethal methods of suicide, namely suicide by firearm and by hanging. Average net salary was negatively correlated with suicide by firearm.

Conclusions: The ratio of males and females who committed suicide was 2.41. In the last three years, this ratio continues to rise in favor of males (reaching 4.29 in 2018). This could be explained by specific cultural features where males are expected to be the main financial contributors to the households. The labor market of Montenegro does not offer adequate opportunities to set and maintain a stable economic situation which puts additional pressure and stress on males.

Introduction

Suicide could be regarded as one of the major public health concerns. It is defined as a deliberate and intentional act of ending one’s own life (Gvion and Apter, 2012). It can be differentiated from suicidal behavior which includes behaviors that do not necessarily end with death, such as deliberate self-harm, non-suicidal self injury, suicidal threats and suicidal gestures (Apter, 2010). In 2016, around 800,000 suicides were committed worldwide, with an annual global age-standardized suicide rate of 10.53 per 100,000 (WHO, 2016). Overall average crude suicide rate in Europe was 15.4 (24.7 in males and 6.6. in females), reported in the same year (WHO, 2016). The crude suicide rate in upper-middle-income countries is approximately 7.5, with males to females ratio of 1.3 (WHO, 2014).

Montenegro belongs to the category of upper-middle-income countries, according to The World Bank (https://data.worldbank.org/income-level/upper-middle-income). It had around 622.400 inhabitants in 2018, according to estimates provided by MONSTAT. In this country, approximately 130 individuals per year die by suicide. For example, a crude suicide rate of 17.84 per 100,000 was reported for year 2016 with reduction of 1.85% up until 2018.

Various factors can influence suicide rates across countries. Most reported are socioeconomic factors such as high unemployment rates (Struckler et al., 2009), unemployment risk and expectations of insufficient financial resources during unemployment (Yuryev et al., 2010). It has been shown that economic crisis such as banking crises during the Great Depression also contributed to the increase in the number of committed suicides (Gunnell et al., 2009).

Population risk factors include (1) lack of social cohesion (fast changes in social structure, social isolation, and economic turmoil), (2) environmental factors (poor access to mental health care services, contents disseminated by the media, and access to lethal means), along with (3) three categories of individual factors (predisposing, mediating, and precipitating factors), as was outlined by Turecki and Brent (2015). These three types of individual factors encompass: genetics and early life adversity (predisposing factors); cognitive deficits, high levels of anxiety, impulsive aggression, chronic substance use (mediating factors), and acute substance use, adverse life events, sense of hopelessness, and behavioral disinhibition (precipitating factors).

In general, social well-being reflects on life satisfaction of human beings, and it is base for stabile and sustainable human development (UNDP, 1994)[1]. Concept of the UNDP refers not only to economic insecurity, but also other sources of social inequalities, uncertainties and dissatisfactions with the quality of life, discrimination, injustice, distrust and more (UNDP, 1994). Also, some studies indicate that subjective well-being inequalities in the community could be addressed as relevant suicide risk factors (McDaid, 2017:36), and concept of subjective well-being encompasses much broader aspects.

Gender plays a major role in attempting or committing suicide. Suicide is more frequently attempted by females unlike males who usually commit suicide more while choosing violent suicide methods (Tsirigotis et al., 2010). For example, male-female ratios of committed suicide is more than 4.0 in most countries in the Balkans (WHO, 2014).

This study aims at determining overall and gender-specific crude suicide rates from 2000 to 2018 in Montenegro and their association with unemployment rate, average monthly net salaries, and two methods of committing suicide (firearms and hanging). The rationale of this study includes the fact that it is the first comprehensive study of suicide in Montenegro based on suicide data collected during extended period of time.

Methods

Until 2009, the data on suicide mortality were collected and published by MONSTAT. From 2009 and on, the Department of Interiors gathers the data on suicide rates and trends and store them within their official registries. Procedure for collecting these data is as follows. In case of a violent death, the first records are provided by the doctor who arrives first to the investigation spot, usually from the Emergency Center. Further on, police examination takes place. Sociodemographic data about the victim are collected and interviews with family members are conducted in order to obtain information on possible causes of suicide. These data are further supported with those from medical documentation. Possible external causes of death are also under inquiry.

Montenegro suicidal data were collected for the last 19 years. The following variables were included in the statistical analysis: overall crude and gender-specific suicide rates, unemployment rates, average monthly net salaries, as well as committing suicide either by firearms or hanging.

Data analysis

First, the average values and range of all the analysed variables were calculated. Next, Spearman’s coefficient of correlation was used to examine the direction and magnitude of relationships among variables.

Results

Based on the data displayed in Table 1, the average suicide rate for the analyzed period was M = 21.06 (29.93 in males and 12.42 in females). The suicide ratio for the same period was 2.41 in favor of men. Furthermore, this ratio reached 4.29 in 2018. The highest overall suicide rate was 26.39 (in 2014) whereas the lowest one was 17.34 (in 2009). In males, the highest suicide rate was reported for year 2014 (42.00) and the lowest rate for year 2013 (22.49). In females, the highest reported suicide rate was 21.62 (in 2015) whereas the lowest one was 6.67 (in 2018).

Figure 1 shows trends in overall crude suicide rates as well as patterns of change in gender-specific suicide rates. From 2009 to 2015, there was a rapid increase and decrease in overall crude suicide rates, which peaked in 2014. In the last three years, this was an increasing trend in males unlike in females, where suicide rates decreased in this period of time.

As shown in Table 2, the unemployment rate ranged from 15.2 (in 2018) to 30.3 (in 2005). The average unemployment rate was 20.52. It should be noticed that the unemployment rates were very high in the period before Montenegrin independence referendum in 2006 (27.7 and 30.3 in 2004 and 2005) and in the year of the referendum (29.6). Next year, the unemployment rate fell to 19.4. With regard to monthly salaries, the lowest one was recorded in 2000 (97 €) and the highest one was that of 2018 (511 €). The average monthly salary for the analysed period was 360.05 €. Average number of suicides committed by firearms was 45.24 (ranging from 30 in 2015 to 58 in 2011) and average number of suicides with the use of hanging was 59.24 (from 44 in 2017 to 72 in 2006).

As shown in Table 3, neither overall nor gender-specific crude suicide rates were associated with year, average net salary, or unemployment rate. Athough statistically insignificant, the relationships of suicide rates with unemployment rates were positive and stronger than those of years and average net salary.

Discussion

The aim of the current study was to provide comprehensive overview of data on suicide rates and trends and their associated variables in Montenegro between 2000 and 2018. Results indicate that Montenegro belongs to the category of countries with high suicide rates (i.e. 20-24.9, e.g. according to Peković, 2010), as this rate is around 21.06. In the last three years (2016–2018), suicide rates reached the point lower than the average rate calculated for that whole period of time, placing Montenegro in the category of countries with moderate suicide rates (i.e. 10-19.9, Peković, 2010). The overall trend in the last three years could be a result of the better quality of mental health services and the increased number of non-governmental organizations (NGOs) primarily focused on different aspects of mental health protection and implementation of projects in this domain. Crude suicide rates in females were much lower compared to those reported before 2016. Injac Stevovic and Vodopic (2017) reported that most suicides attempts by females in Montenegro were associated with poisoning with psychotropic drugs, especially benzodiazepines. Up until 2015, these drugs have been available without a prescription which could explain reduced availability of benzodiazepine in subsequent years.

In comparison to its neighbour countries, Bosnia and Herzegovina and Serbia, Montenegro had higher crude suicide rates for the period 2007–2011 and 2006–2010, respectively. To be more specific, crude suicide rates in Bosnia and Herzegovina ranged from 12.3 in 2008 to 14.6 in 2007 (Bojanić & Srdanović, 2012) whereas in Serbia these rates ranged from 16.58 in 2010 to 19.43 in 2006 (Dedić, 2014). In this period, the lowest crude suicide rate in Montenegro was 17.34 in 2009 and the highest crude suicide rate was 25.69 in 2010.

Overall and gender-specific suicide rates were not in statistically significant relationships neither with year nor with average net salary. Hence, suicide rates did not increase steadily as time passes and this type of rates is not influenced by average net salary growth. It should be taken into account that only data for average salaries were available and not those for median salaries which could be considered as better indicator of individual income.

Nonsignificant correlation between overall suicide rates and unemployment was obtained. This finding was in accordance with findings obtained by Gutierrez-Barroso et al. (2018). In fact, as research evidence showed (e.g. Kim & Cho, 2017), unstable employment is better predictor of suicide rates. However, some studies (e.g. Nordt et al., 2015) revealed that unemployment and lack of job security are important factors that can increase risk of suicide. Other studies (e.g. Agerbo et al., 2002) underlined the possibility that mental health could mediate the relationship between unemployment and suicide rates. In spite of that, numbers of suicides by firearms and hanging were significantly associated with unemployment rate. Additionally, higher net salary seems to have negative relationship with suicide by firearms. In other words, unemployment and low salaries are linked to suicides committed by firearms.

These results should be interpreted with caution as unemployment data may not reflect accurately the labour situation in the country. Official employment and unemployment data do not include information on those who are not looking for a job anymore, those who have been deprived of working abilities, or those who are working in undocumented positions (Yuryev et al., 2010).

Overall suicide rates were relatively stable between 2000 and 2008 with minor oscillations. Notable change can be observed in data from 2009 where the suicide rate drops down below 17.5 and already in 2010 it increases above 25, reaching its highest point of more than 26 in 2014 (placing Montenegro among countries with very high suicide rates). This trend in suicide rates was highlighted by Fountoulakis et al. (2014).

Males are 2.41 times more likely to commit suicide compared to females, which is in accordance to previously conducted studies on gender differences in commiting suicide (Tsirigotis et al., 2010; WHO, 2014). In 2018, this ratio was even 4.29. This finding can be explained with regards to Montenegrin cultural context which imposes high expectations on males in securing financial and material stability of households. Due to these expectations, it is plausible to assume that males in Montenegro are more prone to experience intense stress and pressure during times of economic, political and social disturbances, in comparison to females. Males’ reactions on economical changes related to employment and the average salary, seem to be more severe and lead to more extreme behavioral acts than those of females (Medojević, 2011). The risk of suicide in different population groups change during times of economic crisis or uncertainty. Men are more vulnerable than women to the adverse effects of economic recession, what also include suicide risk (McDaid, 2017:39).

Montenegro, as a small state, goes through the processes of transition (economic, political, social) in last three decades, what causes uncertain political and economic environment, and inevitably effects and concerns for well-being of citizens. By the sources reported from World Bank, poverty in Montenegro dropped about 11% in the mid-2000’s to its minimum of 4.9% in 2008, and rising again to 8.6% in 2013, with a huge proportion of vulnerable categories, which are close to the poverty line (World Bank, 2016). Possibly, it indicates correlation between the suicide ratio and poverty, but also correlation with unstable socioeconomic situation in Montenegro.

The main advantages of the study are summarized as follows. Analysed data were obtained from the reliable and valid source and collected in a systematic way according to official Department of Interior’s procedures. In addition to this, they encompass an extensive time period from 2000 to 2018. Database used in the present study has potential to inform statistical registries on suicide rates and trends of worldwide organizations such as WHO.

Further research should focus on age-adjusted suicide rates in Montenegro and should analyse data for other methods of suicide (e.g. suffocation, drowning, poisoning, wrist cutting). At the same time, these recommendations can be considered as limitations of the present study. Another recommendation could be investigating the relationship of mental health, online and offline social networking, some other socioeconomic characteristics (e.g. marital status and educational level), and urban population growth with crude and age-adjusted suicide rates in Montenegro.

Conclusion

To sum up, male-female suicide ratio increases over time in Montenegro, probably due to unstable socioeconomic situation. Based on crude suicide rates in the last three years, Montenegro belongs to countries with moderate risk for suicide. It seems that unemployment rate does not have significant impact on overall suicide rates; however, number of suicides commited by firearms and hanging was strongly associated with unemployment rates.
