We examined socioeconomic inequalities in initiation and cessation rates of smoking and the resultant inequality in smoking prevalence among 3 consecutive Italian birth cohorts.
We used data from the 1999-2000 Italian National Health Interview Survey, which included 28958 men and 29769 women who were born between 1940 and 1969. The association between smoking variables and level of education was assessed with logistic regression and life table analyses.
Inequalities in the lifetime prevalence of smoking increased across the 3 birth cohorts in Italy. At age 40, lower-educated persons in the youngest cohort reported on average 1 to 5 years of additional exposure to regular smoking compared with higher-educated persons. Inequalities in smoking prevalence increased among both men and women because of widening inequalities in initiation rates. Among women, growing inequalities in cessation rates also played a role.
The relative contribution of initiation and cessation to socioeconomic inequalities in smoking rates varied by both gender and birth cohort. For the youngest birth cohort, policies that address inequalities in smoking should focus on both initiation and cessation.
我们研究了连续3个意大利出生队列中吸烟起始率和戒烟率的社会经济不平等现象，以及由此导致的吸烟流行率不平等。
我们使用了1999 - 2000年意大利国民健康访谈调查的数据，该调查涵盖了1940年至1969年出生的28958名男性和29769名女性。通过逻辑回归和生命表分析评估吸烟变量与教育水平之间的关联。
意大利3个出生队列中吸烟终生流行率的不平等现象有所增加。在40岁时，最年轻队列中受教育程度较低者报告的平均定期吸烟年限比受教育程度较高者多1至5年。由于起始率不平等加剧，吸烟流行率的不平等在男性和女性中均有所增加。在女性中，戒烟率不平等加剧也起到了一定作用。
起始和戒烟对吸烟率社会经济不平等的相对贡献因性别和出生队列而异。对于最年轻的出生队列，解决吸烟不平等问题的政策应同时关注起始和戒烟。
