SOCIODEMOGRAPHIC DETERMINANTS OF STOPPING SMOKING FROM ITALIAN POPULATION-BASED SURVEYS

Frequency and determinants of smoking cessation were analysed using data from two Italian National Health Surveys, conducted in 1983 and 1986-87 on samples of 89 753 and 77 155 individuals respectively, randomly selected within strata of region of residence, size of the municipality and of the household, in order to be representative of the general Italian population. Overall stopping ratios or "quit ratios" (i.e., ratios between ex- and ever-smokers) were 20.5% for males and 9.0% for females in the 1983 survey, and rose to 23.2 and 11.9% respectively in 1986-87. With reference to age, stopping rates were slightly higher for females than for males below age 35, but considerably higher for males in each subsequent age group, particularly in middle age. Ratios were apparently higher for the most recent survey for both sexes and each subsequent age group. After standardisation for age, "quit ratios" in both sexes were directly related with education. Cessation of smoking was more common in northern (and richer) areas of the country, and positively associated with the prevalence of smoking-related chronic diseases. The major, and most discouraging, finding from these analyses is the absolute low rate of stopping in Italy as compared to northern America or northern Europe, although some positive tendency towards increasing cessation was evident between the early and the late 1980s. These tendencies, together with some recent drops in smoking prevalence in younger women, first observed after decades of increase, indicate a change at least in attitudes towards reporting smoking, and hence social acceptance of the habit. Still, women, as well as less educated individuals of both sexes, particularly from the less developed areas of the country, remain major targets for focusing attention and intervention for smoking cessation programmes.
