AIM: Good seat belt fit and positioning is important for crash protection. Older drivers experience problems in achieving good seat belt fit and often reposition seat belts and/or use seat cushions. Comfort influences these behaviours. This work examines the impact of functional morbidities on belt positioning and accessory use and whether comfort mediates this relationship METHODS: Mediation analysis was used to examine the relationship between morbidities affecting physical function, comfort, belt repositions and seat cushion use among 380 drivers aged 75 years and older. RESULTS: Musculoskeletal morbidities increase the likelihood of seat belt repositioning (OR 1.37, 95% CI 1.12-1.67) and comfort partially mediates this relationship (P = 0.03). Morbidities of any type also increase the likelihood of seat cushion use (OR 1.15 95% CI 1.04-1.27), but comfort plays no role in this relationship (P = 0.87). CONCLUSION: Greater awareness among older drivers is needed, to ensure behavioural modifications do not impair their crash protection.
