Youth and young adults (YYAs) are at high risk of cigar use. This study's objective was to examine progression and sociodemographic differences in current cigar use and frequency among new cigar initiators.
We conducted a two-part latent growth model among a nationally representative cohort of cigar initiators (aged 15-25) to examine 24-month trajectories of current cigar use and frequency (n = 1483). The cohort was recruited via address-based sampling with online data collection from 2014 to 2019 and surveyed approximately every 6 months.
The unconditional odds of current cigar use (ie, past 30-day use) within 6 months of initiation was 0.72 (95% confidence interval: 0.63, 0.82), corresponding to a probability of 42%. The odds of current use among recent cigar initiates declined 6 months after initiation and was followed by a stabilization in use over time. Among continued users, frequency (# days used in past 30 days) increased linearly over time but remained low (3.47 days/months at 24 months). Younger individuals, non-Hispanic African Americans, those with lower subjective financial status, and current users of cigarettes, other tobacco products and/or marijuana were at highest risk within 6 months of initiation. Males, younger users, and current cigarette smokers had the highest risk for cigar progression over time.
This study is the first to examine longitudinal cigar use patterns among YYA cigar initiators. Findings emphasize the need for research across the cigar use spectrum and the importance of interventions targeted by age, stage of use, cigarette, other tobacco, and marijuana use and key sociodemographics to interrupt use pathways.
This study is the first to examine progression of cigar use among YYAs who have newly initiated cigars. Results show a high probability of current cigar use within 6 months of initiation followed by a rapid decline and stabilization over time. Frequency increases among those who continue using cigars. Males, younger users, and current cigarette smokers had the highest risk for cigar progression over time. Findings emphasize the need for targeting interventions by age, stage of use, cigarette, other tobacco, and marijuana use and key sociodemographics to interrupt use pathways.
青少年和年轻人（YYAs）使用雪茄的风险很高。本研究的目的是研究新雪茄使用者中当前雪茄使用和频率的进展以及社会人口统计学差异。
我们对一组全国代表性的雪茄使用者（年龄在 15-25 岁之间）进行了两部分潜在增长模型研究，以检查 24 个月内当前雪茄使用和频率的轨迹（n=1483）。该队列是通过基于地址的抽样与 2014 年至 2019 年的在线数据收集招募的，大约每 6 个月调查一次。
在开始后 6 个月内当前雪茄使用（即过去 30 天使用）的无条件几率为 0.72（95%置信区间：0.63，0.82），对应于 42%的概率。最近开始使用雪茄的人中当前使用的几率在开始后 6 个月下降，随后随着时间的推移使用趋于稳定。在继续使用者中，频率（过去 30 天内使用的天数）随时间呈线性增加，但仍然很低（24 个月时为 3.47 天/月）。年轻个体、非西班牙裔非裔美国人、主观经济地位较低的个体以及当前使用香烟、其他烟草制品和/或大麻的个体在开始后 6 个月内风险最高。男性、年轻用户和当前吸烟者在随时间推移的雪茄进展方面风险最高。
本研究首次检查了 YYA 雪茄使用者中纵向雪茄使用模式。研究结果强调了在整个雪茄使用范围内进行研究的必要性，以及针对年龄、使用阶段、香烟、其他烟草制品和大麻使用以及关键社会人口统计学因素进行干预的重要性，以打断使用途径。
本研究首次检查了最近开始吸食雪茄的 YYAs 中雪茄使用的进展情况。结果表明，在开始后 6 个月内有很高的当前吸食雪茄的概率，随后迅速下降并随着时间的推移趋于稳定。继续使用雪茄的人的频率增加。男性、年轻用户和当前吸烟者在随时间推移的雪茄进展方面风险最高。研究结果强调了针对年龄、使用阶段、香烟、其他烟草制品和大麻使用以及关键社会人口统计学因素进行干预的必要性，以打断使用途径。
