Despite decades of tobacco use decline among the general population in the United States, tobacco use among low-income populations continues to be a major public health concern. Smoking rates are higher among individuals with less than a high school education, those with no health insurance, and among individuals living below the federal poverty level. Despite these disparities, smoking cessation treatments for low-income populations have not been extensively tested. In the current study, the efficacy of 2 adjunctive smoking cessation interventions was evaluated among low-income smokers who were seen in a primary care setting.
A total of 846 participants were randomly assigned either to motivational enhancement treatment plus brief physician advice and 8 weeks of nicotine replacement therapy (NRT) or to standard care, which consisted of brief physician advice and 8 weeks of NRT. Tobacco smoking abstinence was at 1, 2, 6, and 12 months following baseline.
The use of the nicotine patch, telephone counseling, and positive decisional balance were predictive of increased abstinence rates, and elevated stress levels and temptation to smoke in both social/habit and negative affect situations decreased abstinence rates across time. Analyses showed intervention effects on smoking temptations, length of patch use, and number of telephone contacts. Direct intervention effects on abstinence rates were not significant, after adjusting for model predictors and selection bias due to perirandomization attrition.
Integrating therapeutic approaches that promote use of and adherence to medications for quitting smoking and that target stress management and reducing negative affect may enhance smoking cessation among low-income smokers.
尽管美国普通人群的吸烟率在过去几十年中持续下降,但低收入人群的吸烟问题仍然是一个主要的公共卫生关注点。受教育程度较低、没有医疗保险和生活在联邦贫困线以下的人群的吸烟率更高。尽管存在这些差异,但针对低收入人群的戒烟治疗方法尚未得到广泛测试。在当前的研究中,评估了两种辅助戒烟干预措施在初级保健环境中接受治疗的低收入吸烟者中的疗效。
共有 846 名参与者被随机分配到动机增强治疗加简短医生建议和 8 周尼古丁替代疗法(NRT)组或标准护理组,标准护理组包括简短医生建议和 8 周 NRT。在基线后 1、2、6 和 12 个月评估烟草吸烟的戒断情况。
使用尼古丁贴片、电话咨询和积极的决策平衡预测了更高的戒烟率,而在社交/习惯和负面情绪情况下的压力水平升高和吸烟诱惑会降低戒烟率。分析表明,干预措施对吸烟诱惑、贴片使用时间和电话联系次数有影响。在调整了模型预测因素和由于随机化后失访引起的选择偏差后,直接干预对戒烟率的影响不显著。
整合促进戒烟药物使用和依从性的治疗方法,并针对压力管理和减少负面情绪,可能会提高低收入吸烟者的戒烟成功率。
