The objective of this investigation was to examine how variation in adolescent physical activity is related to smoking and alternative tobacco use.
Adolescents (N = 1,384) completed a self-report survey every 6 months from ages 14- to 18-years old in a prospective study of health behaviors. The 8 waves of data were analyzed using General Growth Mixture Modeling (GGMM) RESULTS: GGMM identified five physical activity trajectories including stable higher (SHPA), decreased (DPA), stable regular (SRPA), curvilinear (CPA), and stable low (SLPA). Across 4 years, the likelihood of smoking was greater among adolescents in the DPA, SLPA and SRPA trajectories compared to adolescents belonging to the SHPA trajectory. Alternative tobacco use was greatest among adolescents in the DPA and SRPA trajectories.
Adolescents with decreasing physical activity and even adolescents averaging an hour of physical activity a day (SRPA) are important groups to target for tobacco use prevention and intervention efforts.
本研究旨在探讨青少年体育活动的变化与吸烟和其他烟草使用的关系。
在一项针对健康行为的前瞻性研究中,青少年(N=1384)在 14 至 18 岁期间每 6 个月完成一次自我报告调查。使用广义增长混合模型(GGMM)对 8 个波的数据进行分析。
GGMM 确定了五种体育活动轨迹,包括稳定较高(SHPA)、下降(DPA)、稳定常规(SRPA)、曲线(CPA)和稳定较低(SLPA)。在 4 年期间,与属于 SHPA 轨迹的青少年相比,DPA、SLPA 和 SRPA 轨迹中的青少年吸烟的可能性更大。在 DPA 和 SRPA 轨迹中的青少年中,使用替代烟草的情况最为严重。
对于吸烟预防和干预工作来说,活动量减少的青少年,甚至每天平均进行一小时体育活动的青少年(SRPA)都是重要的目标群体。
