Success of a smoking cessation program among smoking relatives of patients with serious smoking-related pulmonary disorders.

The aim of the study was to investigate the success of a smoking cessation program among the smoking relatives of patients with serious smoking-related disorders and to determine whether having a relative with such a disorder influences the rate of success of the program. The relatives of patients with chronic obstructive pulmonary disease (COPD) and lung cancer who wanted to quit smoking were included in the smoking cessation program (group I, n = 34). During the same period, the same number of subjects with relatives free of any smoking-related diseases were included as a control group (group II, n = 34). Intensive behavioral therapy and motivational support was given to all subjects. Nicotine replacement therapy was administered to 10 subjects (29.4%) in group I and 14 subjects (41.2%) in group II. The subjects were evaluated in the 1st, 2nd, 4th, 8th and 12th week and subsequently every 3 months for a year in the outpatient clinic and proactive telephone interviews were performed periodically. In group I, 23.5% of subjects had a relative with COPD, 61.8% had relatives with lung cancer, and 14.7% had relatives with both COPD and lung cancer. The rate of quitting smoking was 79.4 and 73.5% on the 15th day and 41.2 and 38.2% at the end of the 1st year in groups I and II, respectively (p > 0.05). We observed that having a relative with serious smoking-related disorders did not motivate smokers to quit smoking. Copyright 2005 S. Karger AG, Basel.
