Occupational health studies often rely on self-reported secondhand smoke (SHS) exposure. This study examines the accuracy of self-reported tobacco use and SHS exposure.
Data on serum cotinine, self-reported tobacco use, and SHS exposure for US workers were extracted from three National Health and Nutrition Examination Surveys (n = 17,011). Serum cotinine levels were used to classify workers into SHS exposure categories. The percent agreement between self-reported tobacco use and SHS exposure with the cotinine categories was calculated.
Workers reporting tobacco use were 88% accurate whereas workers reporting work, home, or home+work exposures were 87% to 92% accurate. Workers reporting no SHS exposure were only 28% accurate.
Workers accurately reported their smoking status and workplace-home SHS exposures, but substantial numbers reporting "no exposures" had detectable levels of cotinine in their blood, indicating exposure to SHS.
职业健康研究常常依赖自我报告的二手烟暴露情况。本研究考察自我报告的烟草使用及二手烟暴露的准确性。
从三项美国国家健康与营养检查调查（n = 17,011）中提取美国工人的血清可替宁数据、自我报告的烟草使用情况及二手烟暴露情况。血清可替宁水平用于将工人分类到二手烟暴露类别中。计算自我报告的烟草使用及二手烟暴露与可替宁类别之间的一致百分比。
报告使用烟草的工人准确率为88%，而报告在工作场所、家中或工作场所加家中暴露的工人准确率为87%至92%。报告无二手烟暴露的工人准确率仅为28%。
工人准确报告了他们的吸烟状况以及工作场所-家中的二手烟暴露情况，但大量报告“无暴露”的工人血液中可检测到可替宁水平，表明存在二手烟暴露。
