We conducted a longitudinal study of a community-based cohort of HIV-infected indigent adults to examine smoking behaviors and factors associated with quitting. We assessed "hardcore" smoking behaviors associated with a low probability of quitting. Of the 296 participants, 218 were current smokers (73.6 %). The prevalence of "hardcore" smoking was high: 59.6 % smoked ≥15 cigarettes per day, and 67.3 % were daily smokers. During the study interval, 20.6 % made at least one quit attempt. Of these, 53.3 % were abstinent at 6 months. The successful quit rate over 2 years was 4.6 %. Illegal substance use (adjusted odds ratio, AOR 0.2, 95 % CI 0.1-0.6) and smoking within 30 min of waking (AOR 0.2, 95 % CI 0.1-0.7) were associated with lower likelihood of making a quit attempt. Interventions that reduce nicotine dependence prior to smoking cessation and those that are integrated with substance use treatment may be effective for this population.
我们对一个基于社区的贫困 HIV 感染成年人群体进行了一项纵向研究，以研究吸烟行为和与戒烟相关的因素。我们评估了与低戒烟可能性相关的“硬核”吸烟行为。在 296 名参与者中，218 人是当前吸烟者（73.6%）。“硬核”吸烟的流行率很高：59.6%的人每天吸烟≥15 支，67.3%的人是每日吸烟者。在研究期间，20.6%的人至少尝试过一次戒烟。其中，53.3%的人在 6 个月时保持戒断。在 2 年内成功戒烟率为 4.6%。非法药物使用（调整后的优势比，AOR 0.2，95%CI 0.1-0.6）和醒来后 30 分钟内吸烟（AOR 0.2，95%CI 0.1-0.7）与戒烟尝试的可能性降低相关。在戒烟前减少尼古丁依赖的干预措施以及与药物使用治疗相结合的干预措施可能对这一人群有效。
