Motorcycle crash characteristics in Nigeria: implication for control.
ABSTRACT Despite being the second most common cause of road traffic injuries (RTIs) in Nigeria, no study had examined the peculiarities of motorcycle crash site characteristics in Nigeria. We examined and interviewed 363 motorcycle RTI patients in three tertiary hospitals in southwest Nigeria. All the motorcycles are small with capacities between 80 and 125cm3. 68.9% of the patients sustained their injuries while working or going to work and 23.4% on their way to school. 176 (48.5%) of the crashes were with moving vehicles and in 83 (22.3%) cases, either the motorcycle or the other vehicle is moving against the traffic. 37.8% of all crashes occurred at junctions with no roundabout versus 5% at junctions with roundabout. Some risky practices of the patient included carrying more than 2 persons (15.02%), travelling without headlight at night (31.7%) and not wearing helmets (96.5%). This study showed that risky behavior among motorcycle riders, chaotic traffic and road design faults accounted for most of the motorcycle crashes. The implications for the prevention and control of motorcycle injuries were discussed.

ABSTRACT: To investigate whether the risk of motorcycle crash related injuries is associated with the conspicuity of the driver or vehicle. Population based case-control study. Auckland region of New Zealand from February 1993 to February 1996. 463 motorcycle drivers (cases) involved in crashes leading to hospital treatment or death; 1233 motorcycle drivers (controls) recruited from randomly selected roadside survey sites. Estimates of relative risk of motorcycle crash related injury and population attributable risk associated with conspicuity measures, including the use of reflective or fluorescent clothing, headlight operation, and colour of helmet, clothing, and motorcycle. Crash related injuries occurred mainly in urban zones with 50 km/h speed limit (66%), during the day (63%), and in fine weather (72%). After adjustment for potential confounders, drivers wearing any reflective or fluorescent clothing had a 37% lower risk (multivariate odds ratio 0.63, 95% confidence interval 0.42 to 0.94) than other drivers. Compared with wearing a black helmet, use of a white helmet was associated with a 24% lower risk (multivariate odds ratio 0.76, 0.57 to 0.99). Self reported light coloured helmet versus dark coloured helmet was associated with a 19% lower risk. Three quarters of motorcycle riders had their headlight turned on during the day, and this was associated with a 27% lower risk (multivariate odds ratio 0.73, 0.53 to 1.00). No association occurred between risk and the frontal colour of drivers' clothing or motorcycle. If these odds ratios are unconfounded, the population attributable risks are 33% for wearing no reflective or fluorescent clothing, 18% for a non-white helmet, 11% for a dark coloured helmet, and 7% for no daytime headlight operation. Low conspicuity may increase the risk of motorcycle crash related injury. Increasing the use of reflective or fluorescent clothing, white or light coloured helmets, and daytime headlights are simple, cheap interventions that could considerably reduce motorcycle crash related injury and death.BMJ (Clinical research ed.). 05/2004; 328(7444):857.

ABSTRACT: With the introduction of legislation for compulsory crash helmet wear by motorcyclists in Anambra State of Nigeria there was, contrary to expectation, an increase (though not statistically significant) in the case fatality ratio from road crashes involving motorcyclists notwithstanding a high wear rate (96.4%) and use of right type of helmet by the majority (90.9%). The finding that a high percentage did not wear their helmets well-secured was thought to be responsible for this in view of the fact that 61.9% of wrong wearers thought they wore them correctly. This underlines the need for education as a prerequisite to any road traffic accident counter-measure.Accident Analysis and Prevention - ACCID ANAL PREVENT. 01/1980; 12(3):213-216.

ABSTRACT: Earlier studies on alcohol use in Nigeria identified young and middle-aged male adults as mainly concerned. In the last decade however, there has been a noticeable trend of youths getting more and more involved in alcohol use. Some of these latter studies, apart from indicating the increasing involvement of the female sex, have also shown various pathologies associated with alcohol use in Nigeria youths. Most of these reports only looked at alcohol use in the broader context of drug and alcohol abuse in the Nigerian society. However, in the present cross-sectional study of drug use involving 2079 senior secondary school students in two major cities of Nigeria (Ibadan and Abeokuta), prevalence rates of alcohol use was 56% for Ibadan and 51.5% for Abeokuta. The male/female ratio of the users was 1.1:1 in Ibadan and 1.2:1 in Abeokuta. Males used alcohol significantly more than females in each of the two cities (P less than 0.025). Alcohol use was found more common among younger students in the lower school classes and also among those from higher and medium socioeconomic background. Among contributing factors were parental deprivation and delinquency. Alcohol users were also found to be more involved in accidents and the use of other psycho-active drugs than non-users.Drug and Alcohol Dependence 12/1987; 20(3):227-33. · 3.14 Impact Factor
