To determine the accuracy of self-report of cigarette consumption among Mexican American smokers, we compared self-reported cigarette use and serum cotinine concentrations in a sample of 547 participants in the Hispanic Health and Nutrition Examination Survey (HHANES). We defined underreporting of cigarette use as a cotinine to cigarette-per-day ratio of greater than 0.142 microM/l which represented a substantial discrepancy between self-reported consumption and serum cotinine. Of the 98 men and 97 women who reported smoking one to nine cigarettes/day, 20.4 percent and 24.7 percent, respectively, underreported their cigarette consumption. Underreporting was less common among men and women smoking 10 to 19 cigarettes/day (8.3 percent and 10.8 percent, respectively) and 20 or more cigarettes/day (2.2 percent and 2.9 percent, respectively). Comparison of underreporters to other smokers by demographic characteristics within sex and cigarettes/day categories showed no differences. Differences in cotinine metabolism and extremely efficient smoking are alternative explanations that can not be ruled out with these data. We believe, however, that a proportion of Mexican American light smokers may underreport the quantity of cigarettes smoked per day, and may truly be moderate or heavy smokers.
为了确定墨西哥裔美国吸烟者自我报告的香烟消费量的准确性，我们在西班牙裔健康与营养检查调查（HHANES）的547名参与者样本中，比较了自我报告的香烟使用情况和血清可替宁浓度。我们将香烟使用量少报定义为可替宁与每日香烟量的比率大于0.142微摩尔/升，这代表自我报告的消费量与血清可替宁之间存在显著差异。在报告每天吸1至9支烟的98名男性和97名女性中，分别有20.4%和24.7%少报了他们的香烟消费量。在每天吸10至19支烟的男性和女性中（分别为8.3%和10.8%）以及每天吸20支或更多支烟的男性和女性中（分别为2.2%和2.9%），少报情况不太常见。按性别和每日香烟量类别内的人口统计学特征，将少报者与其他吸烟者进行比较，未发现差异。可替宁代谢差异和高效吸烟是无法用这些数据排除的其他解释。然而，我们认为，一部分墨西哥裔美国轻度吸烟者可能少报了每天吸烟的数量，实际上可能是中度或重度吸烟者。
