Factors Associated with Fatalities Among Two and Three-Wheeled Vehicle Users in Road Traffic Accidents in Chaiyaphum Province, Thailand.

Road traffic accidents (RTAs) remain a major public health concern in Thailand, particularly in Chaiyaphum Province. This study aimed to identify factors associated with fatalities among two- and three-wheeled vehicle users in Chaiyaphum province. Secondary data from the Thailand Road Injury and Fatality Integrated Database, encompassing 21,337 accident victims from 2023 to 2024, were analyzed. Descriptive statistics and binary logistic regression were employed. A total of 240 fatalities were recorded, representing a fatality rate of 10.81 per 100,000 population, with an increasing trend observed from 2023 to 2024. Gender, occupation, and accident time were significantly associated with fatalities (p < 0.05). Males (OR = 2.20; 95% CI: 1.36-3.56), students (OR = 2.32; 95% CI: 1.40-3.86), individuals involved in twilight accidents (OR = 1.74; 95% CI: 1.03-2.93), and those involved in nighttime accidents (OR = 2.05; 95% CI: 1.29-3.26) had higher odds of fatality. These findings highlight the need for coordinated efforts among public health agencies, local governments, and law enforcement to strengthen road safety measures, promote safe driving behaviors, enhance crash care systems, and improve nighttime road conditions to reduce preventable fatalities.
