摘要：In July 2003, New York State implemented the Clean Indoor Air Act (CIAA) to reduce exposure to environmental tobacco smoke (ETS). In this cross-sectional study, workers (n=168) completed an interview assessing ETS exposure and provided urine for cotinine analysis. Hospitality workers recruited after implementation of the CIAA had significant reductions in ETS exposure and urine cotinine, compared with those recruited before implementation. The New York State CIAA yielded measurable reductions in ETS exposure for hospitality workers. Exposure to environmental tobacco smoke (ETS) has been linked with a variety of health conditions, including lung cancer, heart disease, stroke, and asthma. 1 – 4 Recently, there has been increased emphasis at the state level on implementing policies that reduce tobacco smoke exposures, especially among persons employed in the hospitality industry. The objective of this study was to examine differences in sources and levels of ETS exposure among hospitality and nonhospitality workers in western New York before and after passage of the statewide Clean Indoor Air Act (CIAA) on July 24, 2003, which eliminated smoking in nearly all indoor public places.
