Collection: European Project ANAMORT Monographs June 2008 Suicide-related deaths in an enlarged European Union Objective using the last available data for a given year. The objective of this monograph is to provide Crude death rate (CDR) was obtained by producers and users of death statistics with a dividing the number of death by the last practical tool to help study deaths related to estimate of the population available in Eurostat suicides. (for a given age group if age specific crude death rate was computed). Age-standardised Methods death rate (SDR) was computed by direct Mortality data produced by health authorities of standardisation, using the 1976 European 33 European countries1 and compiled yearly population . The potential years of life lost by Eurostat2 were used. Depending on their before 75 years-old (PYLL75) due to a given availability, data were used to describe time cause were calculated for each age group by trends, geographical distributions and multiplying the number of deaths related to this demographical risks. cause by the difference between age 75 and By reviewing the literature, the international the mean age at death in each age group. forum for mortality specialists3, the revision Potential years of life lost were the sum of the and update process of the International products obtained for each age group.

SDR for suicide was 10.8 for 100,000 inhabitants in 2005, among the 25 countries of the European Definition of indicators used Union. Variations between 2.9 and 37.0 The number of deaths for each group of /100,000/year according to the countries were underlying causes of death (UCoD) was the observed in Europe (Figure 1). one transmitted by the countries’ national authorities to Eurostat for a given year. The aggregation of number of deaths for the European Union (EU) was made by Eurostat, 1 Included the 25 Member States of the European Union before 2007 , Albania, Bulgaria, Croatia, Iceland, Macedonia, Norway, Romania 6 and Switzerland EU15 comprised the following 15 countries: Austria, Belgium, 2 Denmark, Finland, France, Germany, Greece, Ireland, Italy, http://epp.eurostat.ec.europa.eu 3 Luxembourg, the Netherlands, Portugal, Spain, Sweden, and the http://www.nordclass.uu.se/index_e.htm United Kingdom. 4 33 above mentioned countries, Bosnia Herzegovina, Serbia and 7 EU25 comprised EU15 and the following 10 countries: Cyprus, Turkey Czech Republic, Estonia, Hungary, Latvia, Lithuania, Malta, Poland, 5 http://www.invs.sante.fr/surveillance/anamort Slovak Republic, and Slovenia. * Owing to missing data for 2005, the map Figure 1 Age-standardised mortality rate by suicide in Europe in 2005* In 2005, southern European countries had the lowest SDR by suicide as observed in Cyprus, Greece, Malta, Albania, Italy, Macedonia, Spain, and Portugal. The British islands (United Kingdom and Ireland) and Iceland also had low SDR. Regardless of age, the CDRs by suicide for men were higher than for women (Figure 2). The risk of death by suicide was 3.3 times higher among men Belgium, 2001 for Denmark and 2003 for Italy. (average for EU25 in 2005). In 2005 among EU25 countries, victims were observed among the elderly (65 years-old and more) in 33% of the cases. Compared to 15-24 years-old, the risk of death of the elderly (65 years-old and more) was three times higher. Among men a regular increase of risk was observe after the age of 15. Among women this association with age was also observed between 15 and 49 years old (figure 2).

Definition of intent (sometimes in deaths taking into account the difference between called “manner of death”) is not standardised in intent needed for judicial purposes (as part of a trial) Europe. This may lead to variable underestimation and possible intent which is a purpose of the death of the magnitude of deaths from suicide. This may certificate. be a critical issue in countries where the death Possible values for intent could be: certificates are used for individual purposes and - "no" for disease or accident transmitted to insurance companies, administrations - "suspected or possible homicide" or the public without any ethical approval; in this - "suspected or possible suicide" case a certifier will need much more proof of intent - "undetermined intent" to write the information on the death certificate. In - "other" for operation of war, legal intervention, addition, for some other countries, certifiers do not etc. usually put suicide as the underlying cause of death For the same purposes, common criteria for the as they represent a strong prejudice for cultural and determination of suicide and suspected suicide religious reasons. should be defined. For specific causes of death, some countries may Physicians should be trained to better specify in the apply ICD-10 coding rules differently: hanging, death certificate all information useful for codification where the intention is not determined, may be (circumstances, intent, place and date of external systematically coded as a suicide in many countries factor causing death, etc.).
