A further test of the Finno-Ugrian Suicide Hypothesis: correspondence of county suicide rates in Romania and population proportion of ethnic Hungarians

An Exploratory Analysis of Fifteen Years Suicide Trends Using Population-Level Data From Croatian Committed Suicides Registry

Objectives

The provide a descriptive analysis of the available population-level aggregated data on committed suicides in the Republic of Croatia, in the 2004-2018 period, showing emerging trends in suicide incidence focusing on sex/age/geographical distribution of suicides and the primary and secondary causes of suicide mortality, as well as making comparisons with similar neighboring neighboring countries.

Methods

The aggregated suicide data were obtained from the Croatian Committed Suicides Registry, a national registry maintained by the public health authority. The raw data extract was organized into tables according to several variables (age, sex, place of birth, place of residence, and cause of death). Simple descriptive statistics were performed on the structured data.

Results

Despite being among the highest in the world and EU, the number of committed suicides in Croatia is in decline since 2004. A higher number of suicides by males was observed when compared to females. Most of the suicides occur during spring and summer. The wealthier, northern continental region of the country had the highest average rate of committed suicides per 1,00,000 population, contrary to some of the findings in the published literature associating economic instability with suicide. The most common way to commit suicide for both sexes in all age groups is self-harm by hanging, strangulation and suffocation. Suicide by firearm and explosive devices discharge remains higher than the global average.

Conclusions

Despite its steadily declining incidence rates in the past 20 years, suicides remain a major public health challenge in Croatia. Results may bolster the Ugro-Finnish suicide hypothesis, linking higher suicide rates to regions with populations of Hungarian descent.

Suicide in Hungary-epidemiological and clinical perspectives

Annual suicide rates of Hungary were unexpectedly high in the previous century. In our narrative review, we try to depict, with presentation of the raw data, the main descriptive epidemiological features of the Hungarian suicide scene of the past decades. Accordingly, we present the annual suicide rates of the period mentioned and also data on how they varied by gender, age, urban vs. rural living, seasons, marital status, etc. Furthermore, the overview of trends of other factors that may have influenced suicidal behavior (e.g., alcohol and tobacco consumption, antidepressant prescription, unemployment rate) in the past decades is appended as well. Based on raw data and also on results of the relevant papers of Hungarian suicidology we tried to explain the observable trends of the Hungarian suicide rate. Eventually, we discuss the results, the possibilities, and the future tasks of suicide prevention in Hungary.

Consistency of immigrant suicide rates in Austria with country-of-birth suicide rates: a role for genetic risk factors for suicide?

Multifaceted evidence (family, twin, adoption, molecular genetic, geographic, and surname studies of suicide) suggests genetic risk factors for suicide. The migrant study design is also informative in this context, but underused. In particular, immigrant studies of suicide with a continental European host country are unavailable. The correspondence of suicide prevalence among 22 immigrant groups in Austria (1970-2006) with those of the homelands during the same period was analyzed. Immigrant and homeland suicide rates were significantly positively associated. Controls for age of suicide victim, immigrant group size, national pride, and quality of life in the homelands left the finding essentially unchanged. This correspondence of immigrant and country-of-birth suicide rates is consistent with the assumption of population differences in the prevalence of genetic risk factors for suicide, for which there is emerging evidence.
