摘要：Abstract Background High suicide rates in the Russian North are coupled with high alcohol consumption in the described populations. Objective To investigate the potential role of alcohol consumption on suicides in the Nenets Autonomous Okrug (NAO) in 2002–2012 and to compare this information with corresponding data from the neighboring Arkhangelsk Oblast (AO). Design Retrospective population-based mortality study. Methods Data from autopsy reports were used to identify 252 cases of suicide in the NAO and 1,198 cases in the AO in the period 2002–2012. Postmortem blood alcohol content (BAC) was available for 228 cases in the NAO and 1,185 cases in the AO. BAC as well as other selected variables were compared between the NAO and the AO among women and men, different age groups, ethnic groups, and selected variables of suicide. Results Alcohol was present in the blood of 74.1% of male and 82.9% of female suicide cases in the NAO, which was significantly higher than the proportions found in the AO (59.3% of male and 46.6% female cases). BAC<1.0‰ and between 2.0 and 3.0‰ were more frequently found among suicide cases in the NAO than those in the AO. Conclusions Our findings specify that alcohol drinking may be an essential risk factor for suicide in the NAO, and that this factor may be of greater importance in the indigenous population of the NAO than among Russians in the AO.
