Road safety, alcohol consumption and visual function of motor bike riders in Ekpoma, Edo State, Nigeria
Causes of road traffic accidents (RTA) in developing nations have been attributed in part, to poor vision due to excessive alcohol consumption. This cross-sectional study assessed the visual acuity of 230 male motor-bike riders in Ekpoma, Edo State, Nigeria, and their potentials for alcohol abuse, using the cluster sampling technique.A semi-structured interviewer/self administered questionnaire was used to collect data on socio-demographic characteristics, road traffic accidents and alcohol use, while visual acuity was assessed with a Snellens chart. Results showed good right and left eye vision among 68.3% and 71.3% of the riders respectively, but visual impairment was observed among 25.2% (right) and 26.5% (left) of the riders, and the impairment was severe among 6.5% (right) and 2.2% (left) of them. Up to 69.57% had potential for alcohol abuse, while 5.22% and 25.22% had borderline or no potential for alcohol abuse respectively. About half of the respondents (118; 51.3%) have had a road traffic accident in the last one year and there was a statistically significant association between visual acuity and road traffic accidents (P = 0.000). Although majority of respondents had good visual acuity and a high potential for alcohol abuse, there involvement in road traffic accidents was low.
