Ethanol levels in legally autopsied subjects (2016-2017): Update of data and epidemiological implications in relation to violent deaths in Canary Islands (Spain)

摘要

The aim of this study was to analyze the prevalence of ethanol in individuals (277) subjected to a mandatory medico-legal autopsy in the Institute of Legal Medicine of Las Palmas (Canary Islands, Spain) during 2016-2017, comparing the results with data published in 2015. Blood and/or vitreous humor samples were analyzed by gas chromatography. 31.8% of the individuals were positive to ethanol. We observed a decrease in the prevalence of ethanol among males (p = 0.002). While the prevalence of ethanol was reduced, the concentration among those positive subjects has increased. 11.9% of the series died in a traffic accident and the percentage of positive to ethanol decreased in relation to 2015 (64.3, 25.0, and 35.3%). The number of suicides remains constant, although the age of the suiciders has been significantly reduced (p = 0.022). The results of this study indicate that ethanol is still heavily involved in non-natural deaths.
