Cigarette smoking and changes in smoking among a cohort of Michigan adults, 1980-82

Factors related to cigarette smoking and to changes over two years were investigated in a sample of Michigan adults. Smoking was associated with age, sex, education, occupation, and beliefs regarding its health effects. Cessation was predicted by amount smoked at baseline, desire to stop, and belief concerning difficulty stopping. Starting smoking was associated with time off cigarettes (negatively), age, belief about health effects, sex, and education. Heavy smoking and maintenance of cessation are major problems.
