Guided by the life-course perspective, we examined whether there were subgroups with different likelihood curves of smoking onset associated with specific developmental periods.
Using 12 waves of panel data from 4088 participants in the National Longitudinal Survey of Youth 1997, we detected subgroups with distinctive risk patterns by employing developmental trajectory modeling analysis.
From birth to age 29 years, 72% of female and 74% of US males initiated smoking. We detected 4 exclusive groups with distinctive risk patterns for both genders: the Pre-Teen Risk Group initiated smoking by age 12 years, the Teenage Risk Group initiated smoking by age 18 years, the Young Adult Risk Group initiated smoking by age 25 years, and the Low Risk Group experienced little or no risk over time. Groups differed on several etiological and outcome variables.
The process of smoking initiation from birth to young adulthood is nonhomogeneous, with distinct subgroups whose risk of smoking onset is linked to specific stages in the life course.
本研究以生命历程理论为指导，旨在探讨是否存在与特定发展阶段相关的不同起始吸烟可能性曲线的亚组。
本研究使用了来自国家青年纵向调查 1997 年的 4088 名参与者的 12 波面板数据，通过发展轨迹建模分析检测具有不同风险模式的亚组。
从出生到 29 岁，72%的女性和 74%的美国男性开始吸烟。我们为两性都检测到了 4 个独特的具有不同风险模式的亚组：青少年前风险组在 12 岁前开始吸烟，青少年风险组在 18 岁前开始吸烟，青年成人风险组在 25 岁前开始吸烟，低风险组在整个过程中经历的风险很小或没有。不同的亚组在几个病因和结果变量上存在差异。
从出生到青年成人的吸烟起始过程是不均匀的，存在不同的亚组，其吸烟起始的风险与生命历程中的特定阶段有关。
