青年时期是一个敏感时期，其特点是资源积累和教育、就业、家庭和住房安排的过渡。这些特征与吸烟结果之间的关联可能随年龄而变化，但很少有研究涉及其动态年龄分级性质。为了探索这一点，我们检查了2011-2012年基于吸烟不平等性跨学科研究的横截面样本中的2083名18-25岁的年轻人。我们利用参与者的资源（例如，教育、收入、财政困难）和过渡阶段（即，学习，全职工作，与父母和孩子的生活安排，以及恋爱）。我们使用多项logistic回归模型和基于年龄的相互作用项，研究了这些特征与两年类别（18-19，20-21，22-23和24-25）中偶尔吸烟和每日吸烟之间的差异。调查结果突出了四个特点，即，受教育程度、个人收入、学生身份和关系状况，在不同年龄组与吸烟结果的关联中存在显著差异。在18-19岁和24-25岁年龄组之间：1）低教育程度与每日吸烟之间的负相关增加; 2）个人收入与每日吸烟之间的正相关减少; 3）学生身份与两种结果之间的负相关减少; 4）关系状态与偶尔吸烟之间的负相关增加。研究结果支持年轻人的社会经济特征和吸烟结果之间的关联在生命的第二个和第三个十年期间变化很大。解决这一问题对于确定弱势群体和为这一年龄组制定适当的基于年龄的政策具有重要意义。
Young adulthood is a sensitive period characterized by the accumulation of resources and transitions in and out of education, employment, family, and housing arrangements. The association between these characteristics and smoking outcomes likely varies with age yet few studies address its dynamic age-graded nature. To explore this, we examined 2083 young adults ages 18–25 from the 2011–2012 cross-sectional sample of the Montreal-based Interdisciplinary Study of Inequalities in Smoking. We operationalized participants' socioeconomic characteristics using their resources (e.g., education, income, financial difficulties) and transition stages (i.e., studying, working full-time, living arrangements with parents and children, and being in a relationship). We examined differences in these characteristics' associations with occasional and daily smoking across two-year categories (18–19, 20–21, 22–23, and 24–25) using multinomial logistic regression models with age-based interaction terms. Findings highlighted four characteristics, i.e., educational attainment, personal income, student status, and relationship status, with significant differences in associations with smoking outcomes across age categories. Between the age groups of 18–19 and 24–25: 1) the negative association between low educational attainment and daily smoking increased; 2) the positive association between personal income and daily smoking decreased; 3) the negative association between student status and both outcomes decreased; 4) the negative association between relationship status and occasional smoking increased. Findings support that the associations between young adults' socioeconomic characteristics and smoking outcomes vary substantially during the second and third decades of life. Addressing this has critical implications for identifying vulnerable populations and developing appropriate age-based policies in this age group.
