aThe analysis only included respondents to TUS-CPS aged ≥18 years who reported that they worked indoors and mainly worked in an office building or in another nonresidential indoor place at the time of the interview. Those respondents who reported the presence of a smokefree workplace policy at their place of employment that did not permit smoking in work areas and that also did not permit smoking in indoor public or common areas (such as lobbies, rest rooms, and lunch rooms) were considered to be covered by a smokefree workplace policy. .White collar workers included management, business, and financial occupations (0010–0950); professional and related occupations (1000–3540); sales and related occupations (4700–4960); and office and administrative support occupations (5000–5930). Blue collar workers included installation, maintenance, and repair occupations (7000–7620); and production occupations (7700–8960). Service workers included healthcare support occupations (3600–3650); protective service occupations (3700–3950); food preparation and serving related occupations (4000–4160); building and grounds cleaning and maintenance occupations (4200–4250); and personal care and service occupations (4300–4650).
bRelative difference = 100 × (2010–2011 estimate – 2003 estimate)/2003 estimate. The significant relative differences based on two-proportion z-tests are bolded. A Bonferroni-adjusted p value of .0021 was used as the threshold for the multisubgroup comparisons.
