Illness representations of lung cancer, lung cancer worry, and perceptions of risk by smoking status.

Abstract

We examined perceived risk, worry, and illness representations of lung cancer by smoking status using data from the 2005 Health Information National Trends Survey (n = 1,765). Perceived lung cancer risk was rated "very high" more frequently by current (15.2%) than former (1.9%) and never (1.6%) smokers. Current smokers more frequently reported worry about lung cancer (18.4%) than former (3.1%) and never smokers (1.8%). Confusion about lung cancer prevention was higher among current (55.2%) than former (41.3%) or never smokers (38.2%). Agreement that lung cancer is caused by a person's behavior was higher among never (86.1%) and former (82.6%) than current smokers (75.4%). In multivariable models, never (OR = .07) and former smokers (OR = .16) were less likely than current smokers to perceive their lung cancer risk as high. Never smokers (OR = .21) were significantly less likely than current smokers to report worrying about lung cancer, while former and current smokers did not differ.
