During the nine-month period, five men (three passive smokers and two nonsmokers) and five women (two passive smokers and three nonsmokers) dropped out of the study because of illness, injury or relocation or because they did not complete the diary. These data and data from their respective matched pair were eliminated from the database. Data from 80 subjects were used in the final analysis.
The men ranged in age from 38 to 65 years. Passive smokers averaged 52.6 years (SD = 7.6) and nonsmokers 52.6 years (SD = 7.8). The women ranged in age from 38 to 62 years. Passive smokers averaged 50.2 years (SD = 5.8) and nonsmokers 50.3 years (SD = 6.0). All subjects were Caucasian. Eighty percent of both men and women were currently married. Locations of work and residence according to zip codes were analyzed for population distribution. Subjects were evenly distributed and no zip code area was overrepresented. All subjects were employed and held fulltime positions. Buy Advair Diskus Online
Carbon Monoxide Levels at the Work Site
Carbon monoxide, a component of tobacco smoke, was not intended to be identified as a specific incitive agent, but was used to identify the presence and level of tobacco smoke in the work place. Carbon monoxide is an accurate tobacco smoke marker when no other sources of CO are present and when the ambient levels of CO are subtracted from the measured level.
