Substance use for cognitive enhancement (CE) is a topic of increasing importance. There are only few data about substances, prevalence rates and factors associated with CE. The aim of this study was to assess first data about the use of coffee, caffeinated drinks and caffeine tablets for CE at school and university.
A self-report questionnaire was developed to analyze 1 547 pupils and students about their use of coffee, caffeine tablets, and caffeinated drinks for CE and factors associated with this use.
Lifetime, past-year, and past-month prevalence for the use of coffee for CE was 53.2%, 8.5%, and 6.3%, for the use of caffeinated drinks 39%, 10.7%, and 6.3%, and for the use of caffeine tablets 10.5%, 3.8%, and 0.8%. Use of caffeinated substances for CE was influenced by gender and school grades.
The use of coffee and caffeinated drinks for CE was found to be widespread in the surveyed population. Although the use of caffeine tablets was found to be smaller than the above-mentioned means, it still indicates a relatively high disposition for using tablets for purposes of CE.
物质滥用对认知增强（CE）是一个日益重要的话题。关于物质、流行率和与 CE 相关的因素的数据很少。本研究的目的是评估关于在学校和大学使用咖啡、含咖啡因的饮料和咖啡因片进行 CE 的初步数据。
设计了一份自我报告问卷，以分析 1547 名小学生和学生关于他们使用咖啡、咖啡因片和含咖啡因饮料进行 CE 的情况以及与这种使用相关的因素。
终生、过去一年和过去一个月使用咖啡进行 CE 的比例分别为 53.2%、8.5%和 6.3%，使用含咖啡因饮料的比例分别为 39%、10.7%和 6.3%，使用咖啡因片的比例分别为 10.5%、3.8%和 0.8%。CE 中使用含咖啡因物质受到性别和学校成绩的影响。
在所调查的人群中，发现使用咖啡和含咖啡因的饮料进行 CE 非常普遍。虽然使用咖啡因片的比例低于上述两种方法，但它仍然表明人们对使用片剂进行 CE 的倾向相对较高。
