Gambling as a precipitating factor in deaths by suicide in the National Violent Death Reporting System

Objectives

The public health burden of gambling remains difficult to estimate, given the lack of relevant, available data. Death by suicide, represents a substantial and quantifiable public health cost. The current study reviews data from the National Violent Death Reporting System to detect cases where gambling was identified as a meaningful contextual factor to a death by suicide.

Study design

This study is an exploratory content analysis.

Methods

We analysed narrative data from cases of death by suicide, collected from 2003 to 2020 recorded in the Restricted Access Data of the National Violent Death Reporting System. Gambling-related cases identified in our analysis were compared against all other cases on demographic characteristics, case characteristics, US state, and incident year. Chi-square tests of independence and the Wilcoxon ranked sum tests were used in bivariate comparisons.

Results

Overall, 1306 of 296 317 cases were classified as gambling-related. This represented 0.44% of total cases. Gambling-related classification was over-represented among those identified as Asian (7.0% vs 2.2%) and under-represented among those identified as Black or African American (4.0% vs 6.4%) compared with all other deaths by suicide. Gambling-related cases were also over-represented in cases where alcohol use was suspected (28.0% vs 21.2%), where there were significant financial problems (50.3% vs 8.6%), where there were intimate partner problems (31.5% vs 25.6%), and under-represented in cases where there was a previous mental health diagnosis (35.1% vs 38.8%). The rate of gambling-related cases in Nevada was approximately nine times greater than the rate in the overall sample (4.0% vs 0.44%).

Conclusions

Administrative data can be used to study the impacts of gambling on public health in the absence of quality representative survey data. However, these sources are still likely to underestimate the public health burden of gambling with current structures and procedures. Requiring intentional collection of gambling-related information in cases of suicide would be a significant step towards better quantifying the public health burden of gambling in the United States.
