Road traffic injuries (RTIs) remain a leading cause of morbidity and mortality in Southeast Asia. We aim to estimate the prevalence and predictors of rear seatbelt use, a key behavioural risk factor for RTI, in Bandung and Bangkok, two cities in Southeast Asia. Roadside observational studies were conducted to provide a representative picture of the prevalence in each city. From eight rounds of observations (July 2015 to April 2019), 39,479 and 7,207 rear-seat passengers were observed in Bandung and Bangkok. Across all rounds, 4.2% of rear-seat passengers used seatbelts in Bandung, compared to 8.4% in Bangkok. In both cities, males and adults, as compared to females and adolescents (aged 12-17 years), had higher odds of rear seatbelt use, as did passengers with a restrained driver. Findings highlight the need for rear seatbelt laws in Bandung and improved enforcement of existing rear seatbelt laws in Bangkok.
