PURPOSE: Few studies have compared acute use of alcohol in suicide decedents with that in a nonsuicide group. This study provides the first national analysis of acute use of alcohol before suicide compared with an estimate of acute use of alcohol in a living sample. METHODS: Pooled 2003-2011 National Violent Death Reporting System data were used to estimate the prevalence of postmortem blood alcohol content positivity (blood alcohol content >0.0 g/dL) and intoxication (blood alcohol content β₯0.08 g/dL). Population estimates of comparable use of alcohol (within the past 48 hours) were based on the National Epidemiologic Survey on Alcohol and Related Conditions. RESULTS: Compared with the living sample, male and female suicide decedents showed, respectively, a 1.83-fold (95% confidence interval [CI], 1.73-1.93) and 2.40-fold (95% CI, 2.24-2.57) increased risk of alcohol ingestion before their death after age, race/ethnicity, and chronic alcohol problems were controlled. Furthermore, male and female decedents exhibited, respectively, a 6.18-fold (95% CI, 5.57-6.86) and a 10.04-fold (95% CI, 8.67-11.64) increased risk of being intoxicated before their death after confounders were considered. CONCLUSIONS: The findings underscore the crucial need to include among the essential components of suicide prevention policies programs that minimize the use of alcohol, particularly drinking to intoxication.
Study population in the National Violent Death Reporting System (NVDRS), 2003β2011 BAC = blood alcohol concentration; BAC+ = BAC positivity (BAC > 0.0 g/dl)
LLM interpretation
This is a flow diagram illustrating the study population of suicide decedents ($N = 82,519$) from the NVDRS between 2003 and 2011. The population is divided by sex into males ($N = 64,660$; 78%) and females ($N = 17,845$; 21%). For each group, the chart tracks the number of individuals who underwent blood alcohol concentration (BAC) testing and the subset that tested positive (BAC+), showing a higher positivity rate in males (36%) compared to females (28%).
