This study examined the association between young age and poor road safety practices of commercial motorcyclists in Oyo state, Nigeria.
A cross-sectional study of 371 commercial motorcyclists selected via a multistage sampling technique was conducted. Information on sociodemographic characteristics and road safety practices (possession of a valid license, helmet use, number of passengers carried per trip, and compliance with 10 selected traffic signs) was obtained with the aid of an interviewer-administered questionnaire. Individual road safety practice items were scored and a total score was obtained giving minimum and maximum obtainable scores of 0 and 35. Respondents with scores ≤ 17.5 (i.e., less than or equal to half of the maximum obtainable score of 35) were categorized as having poor road safety practices. Descriptive statistics, chi-square, and multiple logistic regression tests were conducted. Selected sociodemographic and occupation-related factors were controlled for in the logistic regression analysis.
All respondents were male, 80.1% had been riding for commercial purposes for less than 5 years, and 73.0% had other jobs in addition to commercial riding. Road safety practices were generally poor; that is, 84.4% of commercial riders were categorized as having poor road safety practices. Almost all (98.6%) respondents aged < 25 years compared to 84.3% of those aged 25 to <35 years and 76.8% of those ≥35 years had poor road safety practices. This difference was statistically significant. Following logistic regression, younger age (<25 years) remained predictive of poor road safety practices. Motorcyclists aged < 25 years had about 16 times higher odds of having poor road safety practices compared to those aged 35 years and more (odds ratio = 15.72, 95% confidence interval, 1.82-135.91).
Most studies conduct only bivariate analysis to test the association between age and road practices of commercial motorcyclists; however, we investigated the influence of potential confounding variables using multivariate analysis. Our findings confirmed young age as a predictor of poor road safety practices among our sample of commercial motorcyclists and emphasizes the need for road safety programs to target this category of riders. The current minimum age for obtaining a rider's license in Nigeria is 18 years; our findings suggest that it might be beneficial to increase the age at which riders in our study area can obtain a commercial rider's license to above 25 years.
本研究调查了尼日利亚奥约州商业摩托车骑手年龄较小与道路安全行为不佳之间的关联。
采用多阶段抽样技术选取了371名商业摩托车骑手进行横断面研究。借助访谈式问卷获取了社会人口学特征和道路安全行为（拥有有效驾照、佩戴头盔、每次搭载乘客数量以及对10个选定交通标志的遵守情况）方面的信息。对各项道路安全行为项目进行评分，得出总分，最低和最高可得分数分别为0分和35分。得分≤17.5分（即小于或等于最高可得分数35分的一半）的受访者被归类为道路安全行为不佳不佳。进行描述性统计、卡方检验和多元逻辑回归分析。在逻辑回归分析中对选定的社会人口学和职业相关因素进行了控制。
所有受访者均为男性，80.1%从事商业骑行的时间不到5年，73.0%除商业骑行外还有其他工作。道路安全行为总体较差；也就是说，84.4%的商业骑手被归类为道路安全行为不佳。与25至<35岁年龄段的84.3%以及≥35岁年龄段的76.8%相比，几乎所有（98.6%）年龄<25岁的受访者道路安全行为不佳。这种差异具有统计学意义。经过逻辑回归分析，年龄较小（<25岁）仍然是道路安全行为不佳的预测因素。与35岁及以上的骑手相比，年龄<25岁的摩托车骑手道路安全行为不佳的几率高出约16倍（优势比=15.72，95%置信区间，1.82 - 135.91）。
大多数研究仅进行双变量分析来检验商业摩托车骑手年龄与道路行为之间的关联；然而，我们使用多变量分析调查了潜在混杂变量的影响。我们的研究结果证实，在我们的商业摩托车骑手样本中，年龄较小是道路安全行为不佳的一个预测因素，并强调道路安全计划需要针对这类骑手。尼日利亚目前获得骑手执照的最低年龄是18岁；我们的研究结果表明，将我们研究区域内骑手获得商业骑手执照的年龄提高到25岁以上可能是有益的。
