THE HEALTH IMPACT OF PROLONGED TRICYCLE (KEKE) DRIVING WITH INAPPROPRIATE SITTING POSITION IN FREETOWN, SIERRA LEONE

Abstract

This study investigates the health impact of prolonged tricycle (Keke) driving with inappropriate sitting positions among drivers in Freetown, Sierra Leone. Tricycle transportation is a vital mode of public transportation in the city, and many drivers are exposed to long hours of suboptimal seating postures. The primary objective of this research is to assess the health consequences of such conditions and identify potential interventions to improve the well-being of Keke drivers. To achieve the objective, an extensive literature was reviewed and a unique research model was developed. We collected data from 513 Keke drivers and employed the structural equation model (SEM) approach to test the research hypothesis and consequently address the objectives. The results show that, prolonged inappropriate sitting position and ergonomic factors have negative health impacts on Keke drivers. The results further show that, increased levels of mental stress exacerbate the negative health outcomes associated with prolonged and poor sitting ergonomics. The findings also show that taller drivers experience heightened discomfort and health impacts compared to shorter drivers. For policy, it is suggested that implementing ergonomic features such as proper lumbar support, adjustable seat height, and optimal seating angles will mitigate physical strain and discomfort experienced by drivers, thereby reducing the incidence of chronic back pain, spinal deformities, and other musculoskeletal issues. This recommendation underscores the potential of ergonomic interventions to improve the health and well-being of Keke drivers, emphasizing the importance of prioritizing ergonomic considerations in tricycle design and maintenance.
