Characteristics of sauna deaths in Korea in relation to different blood alcohol concentrations

Abstract

Although the benefits of sauna bathing have been demonstrated in epidemiological studies, sauna deaths have been reported. The aim of this study was to determine the demographic and forensic characteristics associated with different blood alcohol concentrations (BACs) in sauna deaths in Korea. In this retrospective analysis, data were collected from a nationwide pool in Korea between January 2008 and December 2015 to determine the role of alcohol intoxication in sauna deaths based on the subjects’ BAC and to evaluate the demographic and forensic characteristics associated with different BACs. One hundred and three deaths were classified into 2 groups: the non-intoxication (NI) group (BAC,<0.08%; n = 27) and the intoxication (I) group (BAC,≥0.08%; n = 76). Demographic and forensic characteristics were compared between the groups using a multinomial logistic regression analysis. The proportions of decedents who were male (odds ratio: 17.4, 95.0% confidence interval: 3.8–79.8) and in a prone position at the scene of death (odds ratio: 11.3, 95.0% confidence interval: 2.1–60.1) were significantly higher (P < 0.001 and P < 0.05, retrospectively) in the I group than in the NI group. However, no significant differences were observed with respect to obesity, coronary artery narrowing, and liver pathology. Sauna deaths exhibited different characteristics according to BACs detected at autopsy. The differences in sauna deaths between the I and NI groups may have implications for the targeted prevention of sauna deaths associated with alcohol consumption.
