As smoking initiation generally occurs in adolescence, smoking prevention is targeted primarily at young adolescents (aged below 16 years). We hypothesize that, with the adoption of increasingly stronger youth access laws, a shift in the age of smoking initiation may have occurred.
Repeated cross-sectional survey.
The Netherlands.
A total of 13 163 respondents born between 1980 and 1995.
In the 2010-15 National Health Survey we measured retrospectively self-reported initiation rates per year of age by birth cohort (1980-83, 1984-87, 1988-91, 1992-95). Logistic regression analyses were performed to assess differences between cohorts, per sex and educational level.
Of those who started smoking, 67.2% initiated smoking between 12 and 16 years of age. Contrary to our hypothesis, no shift in initiation towards higher ages was observed. The peak age of initiation was 16 years for all cohorts. Initiation at ages 17-21 was lower in younger birth cohorts than in older birth cohorts [e.g. cohort 1993-95 versus 1980-83: odds ratio (OR) for initiating at 19-21 years = 0.45, 95% confidence interval (CI) = 0.31-0.64]. Trends in age of initiation were similar for males and females. Initiation at ages 15-17 decreased across cohorts for respondents in higher education levels, but not for those in lower education levels.
In the Netherlands, the peak age of smoking initiation did not shift throughour subsequent cohorts born between 1980 and 1995, suggesting that young adolescents remain the main target group for smoking initiation prevention policies.
由于吸烟通常始于青少年时期，因此吸烟预防主要针对青少年（16 岁以下）。我们假设，随着越来越严格的青少年接触法律的通过，吸烟起始年龄可能已经发生了变化。
重复的横断面调查。
荷兰。
共有 13163 名出生于 1980 年至 1995 年之间的受访者。
在 2010-15 年全国健康调查中，我们通过出生队列（1980-83、1984-87、1988-91、1992-95）回顾性地测量了每年自我报告的起始率。使用逻辑回归分析按性别和教育水平评估队列之间的差异。
那些开始吸烟的人中，67.2%在 12 至 16 岁之间开始吸烟。与我们的假设相反，没有观察到起始年龄向更高年龄的转移。所有队列的起始年龄峰值均为 16 岁。在年轻的出生队列中，17-21 岁的起始年龄低于年龄较大的出生队列[例如，1993-95 队列与 1980-83 队列相比：19-21 岁开始吸烟的比值比（OR）为 0.45，95%置信区间（CI）为 0.31-0.64]。男性和女性的起始年龄趋势相似。在较高教育水平的受访者中，各队列的 15-17 岁起始年龄均呈下降趋势，但在较低教育水平的受访者中则没有。
在荷兰，1980 年至 1995 年之间出生的后续队列中，吸烟起始的高峰期并未转移，这表明青少年仍然是吸烟起始预防政策的主要目标群体。
