Abstract.
Smoking cessation counseling is a central part of the Medicare guidelines for
lung cancer screening. With increasing age, many heavy smokers eventually stop
smoking, however factors influencing the decision to stop smoking are poorly
understood. We postulated declining health or physician-diagnosis of a medical
condition may be associated with successful smoking cessation.
Methods. A
total of 4,448 current and former smokers in Phase 2 COPDGene answered a
question about reasons for stopping smoking. Subjects were classified as
successful quitters (n=3345), and unsuccessful quitters (n=1003). Reasons cited
for quitting were grouped as: medical diagnoses, social factors, symptoms.
Logistic modeling of factors associated with successful quitting were adjusted
for age, gender, race and education.
Results.
The most common factors cited for a quit attempt by all respondants were
medical diagnoses (48%), followed by social factors (47%) and respiratory
symptoms (36%). Successful quitters were more likely to be older, male and
non-Hispanic white. An adjusted model found increased age, white race,
education beyond high school and male sex favored successful quitting while
ther cited medical diagnoses, social factors and "other" reasons were
associated with unsuccessful quitting. Fagerstrom Nicotine Dependence Scores
were ³ 5 in 54% of unsuccessful group compared to 45% for successful quitters, p<0.0001
suggesting some increased nicotine dependence in the unsuccessful quitters.
Conclusions.
Medical diagnoses were the most common factor cited for considering a quit
attempt by both successful and unsuccessful quitters However, successful
quitting was influenced by demographic factors and potentially the severity of
nicotine dependence.
