Plasma cotinine levels were measured in 137 students (ages 14 to 17 years), as an independent validation of self-reported cigarette smoking status. Ninety-five per cent of the students who reported daily cigarette smoking had detectable cotinine levels. In contract, only 2 per cent of students who reported that they never smoke cigarettes had detectable levels of plasma cotinine. Results suggest that adolescents can report accurately on their smoking status if sufficient assurance of confidentiality is stressed.
对137名学生(年龄在14至17岁之间)的血浆可替宁水平进行了测量,作为对自我报告吸烟状况的独立验证。报告每天吸烟的学生中有95%的人血浆可替宁水平可检测到。相比之下,报告从不吸烟的学生中只有2%的人血浆可替宁水平可检测到。结果表明,如果强调足够的保密保证,青少年能够准确报告他们的吸烟状况。
