Denial and minimization in self-reports of cigarette smoking are probable common among youth and other groups where smoking is discouraged. Chemical measures may obtain more accurate measurement of smoking habits in those groups. One such measure, saliva thiocyanate (SCN), was evaluated in 1,419 eighth grade students. In that group, 54.9% of students admitted to regular smoking of greater than one pack/week had thiocyanates greater than or equal to 100 m g/ml compared to 2.3% nonsmokers at those levels. Of students who smoked greater than or equal to 10 cigarettes in the prior 24 hours, 66.7% were at or above 100 microgram/ml. Elevated SCN in nonsmokers was uncommon. Saliva SCN is a safe, inexpensive, and acceptable prevalence measurement for cigarette smoking. It can be used in place of self-reports to document smoking of greater than on pack/week in populations of youth.
在青少年以及其他不鼓励吸烟的群体中,吸烟自我报告中的否认和瞒报现象可能很常见。化学检测方法或许能更准确地测定这些群体的吸烟习惯。其中一种检测方法,即唾液硫氰酸盐(SCN),在1419名八年级学生中进行了评估。在该群体中,承认每周常规吸烟超过一包的学生中,有54.9%的硫氰酸盐含量大于或等于100毫克/毫升,相比之下,非吸烟者中该水平的比例为2.3%。在前24小时内吸烟大于或等于10支的学生中,66.7%的唾液硫氰酸盐含量达到或高于100微克/毫升。非吸烟者中硫氰酸盐含量升高的情况并不常见。唾液硫氰酸盐是一种安全、廉价且可接受的吸烟流行率检测方法。它可用于替代自我报告,以记录青少年群体中每周吸烟超过一包的情况。
