Effects of a Province-Based Strategy to Prevent Suicide Using Charcoal Burning: A Preliminary Time Series Analysis

The suicide rate in Korea has been declining steadily after peaking in 2011. However, to date, time-series analyses of Korean suicide rate data have mainly addressed factors related to increases in suicide rates. This study analyzed one of the most important evidence-based public health strategies to decrease suicide, that is, preventive effects of restricting access to lethal means via a charcoal-selling procedure improvement campaign, using multivariate time series analysis. The results showed the campaign in Gyeonggi Province had a significant effect on decreasing the number of charcoal-burning suicides in this area. It is believed that the present study has important implications in terms of providing the first empirical evidence for the charcoal-selling procedure improvement campaign in Korea. Further repeated research is needed to evaluate the impact of the intervention when the more enough observational data become available.

Overview of Suicide by Charcoal Burning and Prevention Strategies / 신경정신의학

Suicide by charcoal burning is common in Asian countries such as Hong Kong and Taiwan. Suicide by charcoal burning has recently shown a rapid increase in Korea, following a celebrity suicide, which was extensively reported by the media. Not only is suicide by charcoal burning fatal, but it also causes delayed neuropsychiatric symptoms through carbon monoxide poisoning. Risk factors associated with charcoal-burning suicide include middle age, male, divorced or unmarried, and economically active but with financial difficulties. To prevent suicide by charcoal burning, limited access to charcoal, responsible media reporting as recommended by international guidelines, and detoxification of charcoal by modifying the raw material should all be considered. In addition, suicide prevention programs should increasingly focus on suicide by charcoal burning. Relevant measures to prevent suicide by charcoal burning will be essential in order to lower the overall suicide rate in Korea.

Trends and Risk Factors of the Epidemic of Charcoal Burning Suicide in a Recent Decade among Korean People

The aims of this study were to analyze annual trends of charcoal burning (CB) suicide, 2000 to 2011, and to examine the risk factors of CB suicide in Korea. Data on suicides (n=138,938) were obtained from the Statistics Korea. The proportion of CB suicides among all suicide deaths reported was 0.7% (84 cases) in 2007, and since 2008 it has rapidly increased to 7.9% (1,251 cases) in 2011. Of significant risk factors of CB suicide, the presence of the media report of Ahn's suicide was the greatest risk factor (adjusted odds ratio, 11.69; 95% CI, 10.30-13.23) of the initial phase of the continuing CB suicides since 2008. Korean Government should urgently consider effective measures against CB suicide, including enforced media regulations on reporting such suicides.
