Substance use among fatally-injured pedestrians in New York State, USA: a retrospective analysis.

BACKGROUND

Pedestrian fatalities remain a public health burden. Risky behaviours by pedestrians such as alcohol or drug use are understudied. This study aims to quantify the prevalence and characteristics of substance use among pedestrian fatalities in New York State, USA.

METHODS

The Fatality Analysis Reporting System was used to capture New York State pedestrian deaths from 2018 to 2020. Substance use was defined as the presence of alcohol, drugs, or both. Pedestrian death rates were calculated by age and sex. Statistical analyses used χ2, Fisher's exact test or t-test with significance defined as p<0.05.

RESULTS

Of 771 pedestrian deaths, 43.8% involved substance use. Drug-only involvement accounted for 18.3% of all deaths, which was slightly higher than alcohol-only involvement (13.7%) and alcohol and drug co-use (11.8%). Substance-involved deaths were more common among males than females and varied by circumstances such as time of day and pedestrian location.

CONCLUSIONS

Nearly half of pedestrian deaths in New York State involved substance use by the pedestrian. Public safety campaigns that traditionally emphasise drinking and driving should also address the dangers of walking while impaired. Interventions should encourage planning for safe travel and target high-risk groups.
