Joinpoint regression analysis of suicides in Denmark during 1980-2015

Is the suicide rate in Denmark increasing or decreasing? Effective suicide prevention requires vigilant monitoring of suicide trends. The aim of this study was to assess the change in the Danish suicide rate over time using joinpoint regression analysis. The suicide rate fell sharply between 1980 and 1999 in Denmark, but since then the decrease has been modest, especially since 2007. Further reduction in the suicide rate requires new and effective measures. The study is published in Danish Medical Bulletin

Suicide among persons in same- sex and opposite-sex marriages in Denmark and Sweden

People belonging to sexual minority groups have higher levels of suicidality than heterosexuals. However, findings regarding suicide death are sparse. Using national data from Denmark and Sweden, this study investigated whether individuals entering a same-sex marriage have higher suicide rates than those entering opposite-sex marriage.

The findings revealed that people in same-sex marriages have a 1.5-fold higher suicide rate when compared to people living in opposite-sex marries. Over the periods 1989-2002 and 2003-16, the rate of suicides among people in same-sex unions fell by 46%, compared to a decline of about 28% in the number of suicides by people in heterosexual relationships.

“Although suicide rates in the general populations of Denmark and Sweden have been decreasing in recent decades, the rate for those living in same-sex marriage declined at a steeper pace, which has not been noted previously,” the study, which followed 28,000 people in same-sex partnerships for an average of 11 years, concludes Annette Erlangsen, the lead author, suggested that along with other gay rights legislation, same-sex marriage may have reduced feelings of social stigmatisation among some homosexual people. “Being married is protective against suicide,” she told Thomson Reuters Foundation
