Recent insights into substance use cessation suggest that outcomes short of long-term abstinence are clinically meaningful and may offer more realistic incremental goals, particularly for highly vulnerable individuals. With the goal of informing tobacco treatment programs, we examined distinct patterns of cigarette smoking and their association with the ongoing use of other substances in women who experience housing instability.
We recruited participants from a longitudinal study of women experiencing housing instability. Between June 2017 and January 2019, participants completed six monthly survey interviews regarding social conditions and the use of multiple substances. We examined associations between cigarette smoking intensity, including number of cigarettes smoked per day, heavy smoking, and an increase in number of cigarettes smoked from the previous 30-days, and other substance use in the past 7-days.
Of the 243 participants, 69 % were current smokers and 58 % were daily smokers. Number of cigarettes smoked per day (Adjusted odds ratio [AOR] 1.02, 95 % CI 1.00-1.03), heavy cigarette smoking, compared to none or light smoking (AOR 2.02, 95 % CI 1.46-2.79), and an increase in number of cigarettes smoked from the previous 30-days (AOR 1.06, 95 % CI 1.01-1.12) were all significantly associated with methamphetamine use in the past 7-days. Associations with other substance use were not as strong.
In a sample of unstably housed women, where almost half used multiple substances, methamphetamine use was associated with higher cigarette smoking intensity. Our findings highlight a potential role for integrating tobacco and methamphetamine use treatment to reduce tobacco use among unstably housed women.
最近对物质使用戒除的深入了解表明，短期戒除的结果具有临床意义，并且可能提供更现实的渐进目标，特别是对于高度脆弱的个体。为了为烟草治疗计划提供信息，我们研究了住房不稳定的女性中不同的吸烟模式及其与其他物质持续使用的关联。
我们从一项关于住房不稳定女性的纵向研究中招募了参与者。在 2017 年 6 月至 2019 年 1 月期间，参与者完成了六次关于社会状况和多种物质使用的每月调查访谈。我们研究了吸烟强度（包括每天吸烟的数量、重度吸烟以及与前 30 天相比吸烟数量的增加）与过去 7 天内其他物质使用之间的关联。
在 243 名参与者中，69%为当前吸烟者，58%为每日吸烟者。每天吸烟的数量（调整后的优势比 [AOR] 1.02，95%CI 1.00-1.03）、与不吸烟或轻度吸烟相比的重度吸烟（AOR 2.02，95%CI 1.46-2.79），以及与前 30 天相比吸烟数量的增加（AOR 1.06，95%CI 1.01-1.12）均与过去 7 天内使用冰毒显著相关。与其他物质使用的关联则不那么强。
在一个不稳定住房的女性样本中，几乎一半的人使用多种物质，冰毒使用与更高的吸烟强度相关。我们的研究结果强调了将烟草和冰毒使用治疗相结合以减少不稳定住房女性吸烟的潜在作用。
