To estimate prevalence and identify correlates of age of smoking initiation among adolescents in Africa.
Data (n = 16,519) were obtained from nationally representative Global Youth Tobacco Surveys in nine West African countries. Study outcome was adolescents' age of smoking initiation categorized into six groups: ≤7, 8 or 9, 10 or 11, 12 or 13, 14 or 15 and never-smoker. Explanatory variables included sex, parental or peer smoking behavior, exposure to tobacco industry promotions, and knowledge about smoking harm. Weighted multinomial logit models were conducted to determine correlates associated with adolescents' age of smoking initiation.
Age of smoking initiation was as early as ≤7 years; prevalence estimates ranged from 0.7 % in Ghana at 10 or 11 years age to 9.6 % in Cote d'Ivoire at 12 or 13 years age. Males, exposures to parental or peer smoking, and industry promotions were identified as significant correlates.
West African policymakers should adopt a preventive approach consistent with the World Health Organization Framework Convention on Tobacco Control to prevent an adolescent from initiating smoking and developing into future regular smokers.
评估非洲青少年开始吸烟的流行情况，并确定其相关因素。
数据（n = 16519）来自9个西非国家具有全国代表性的全球青少年烟草调查。研究结果是将青少年开始吸烟的年龄分为6组：≤7岁、8或9岁、10或11岁、12或13岁、14或15岁以及从不吸烟者。解释变量包括性别、父母或同伴的吸烟行为、接触烟草行业促销活动以及对吸烟危害的了解。采用加权多项logit模型来确定与青少年开始吸烟年龄相关的因素。
开始吸烟的年龄早至≤7岁；患病率估计范围从加纳10或11岁时的0.7%到科特迪瓦12或13岁时的9.6%。男性、接触父母或同伴吸烟以及行业促销活动被确定为显著相关因素。
西非政策制定者应采取与《世界卫生组织烟草控制框架公约》一致的预防方法，以防止青少年开始吸烟并发展成为未来的经常吸烟者。
