Smoking Cessation in a Prospective Study of Healthy Adult Males: Effects of Age Time Period and Amount Smoked

摘要

The present study examined effects on smoking cessation of three variables—chronological age, time period, and amount smoked—in 637 healthy male smokers aged 22-69 at baseline. Subjects were followed from 1962-1975 using life table procedures. Age was not significantly related to quitting rates (p = .150). The amount smoked effect approached significance (p = .096) with rates of quitting progressively lower at higher consumption levels. Powerful time-period effects were found (p = .008). Incidence rates of quitting increased from 1962-1970, after which a marked decline occurred. (Am J Public Health 1983; 73:446-450.)
