Abstract：
This study aimed to assess the prevalence of drinking and driving on roadways in urban areas and highways in Cameroon, and to determine the associations between drinking and driving and socio-demographic factors.
A cross-sectional study of motor vehicle drivers was performed on Fridays, Saturdays, and Sundays between May and September 2020 with three driver groups: (1) random motor vehicle drivers (including riders) on major highways, (2) drivers recruited at car stations in Yaoundé, and (3) at fuel stations in Douala. Alcohol was measured using breathalyzers, and a questionnaire collected socio-demographic data.
In total, 2402 motor vehicle drivers were asked to participate in the study and 1701 (70.8%) gave informed consent. The vast majority (98.6%) were men. Drivers aged 30-39 years constituted the largest age group on highways and in Yaoundé, whereas 18-29 years was the largest age group in Douala. The highest prevalence of alcohol was observed among drivers in Yaoundé, which included mainly clandestine taxi car drivers and motorcycle taxi riders, where about 30% had blood alcohol concentrations (BAC) above the legal limit of 0.08%. The proportion with BACs above the legal limit was about 6% among the drivers in Douala, which included mainly motorcycle taxi riders, and about 4% among drivers on highways.
The findings indicate that drinking and driving is a major traffic safety problem on Cameroonian public roads, especially among motorcycle taxi riders and clandestine taxi drivers in towns, which represent the major mass transportation means in the country. Drinking and driving education and legislation should be better developed and enforced in order to reduce the number road traffic crashes.

摘要：
这项研究旨在评估喀麦隆城市地区和高速公路道路上饮酒和驾驶的患病率，并确定饮酒和驾驶与社会人口因素之间的关联。
在星期五对机动车驾驶员进行了横断面研究，星期六,和2020年5月至9月的星期日，三个司机组：（1）主要高速公路上的随机机动车司机（包括骑手），(2)在雅温得的汽车站招募的司机，和（3）在杜阿拉的加油站。酒精是用酒精测试仪测量的，问卷收集了社会人口统计数据。
总共，2402名机动车驾驶员被要求参加研究，1701（70.8％）给予知情同意。绝大多数（98.6%）是男性。30-39岁的司机是高速公路和雅温得最大的年龄组，而18-29岁是杜阿拉最大的年龄组。雅温得的司机中酒精患病率最高，其中主要包括秘密出租车司机和摩托车出租车司机，其中约30％的血液酒精浓度（BAC）高于0.08％的法定上限。在杜阿拉的司机中，超过法定限额的BAC的比例约为6%，其中主要包括摩托车出租车司机，高速公路上的司机中约有4%。
调查结果表明，酒后驾车是喀麦隆公共道路上的主要交通安全问题，特别是在城镇的摩托车出租车司机和秘密出租车司机中，代表了该国主要的大众交通工具。应该更好地发展和执行酒后驾驶教育和立法，以减少道路交通事故的数量。
