The prevalence of cigarette smoking is particularly high among American Indian communities in the Upper Midwest.
To evaluate the predictors of smoking cessation among a population-based sample of American Indians in the Upper Midwest during a quit attempt aided with nicotine replacement therapy (NRT).
This study used the subsample of American Indian adults (n = 291, response rate = 55.4%) from a cohort study of smokers engaging in an aided NRT quit attempt. Eligible participants filled an NRT prescription between July 2005 and September 2006 through the Minnesota Health Care Programs (e.g., Medicaid). Administrative records and follow-up survey data were used to assess outcomes approximately 8 months after the NRT fill date. This analysis was conducted in 2009-2010.
Approximately 33% of American Indian respondents trying to quit smoking reported complete home smoking bans. Adoption of a complete home smoking ban and greater perceived advantages of NRT were cross-sectionally associated with 7-day smoking abstinence in univariate and multivariate analyses. Consistent with previous research, older age was a significant predictor of 7-day abstinence. Having a history of clinician-diagnosed anxiety in the past year was associated with decreased likelihood of 7-day abstinence in the unadjusted analysis, but not significant in multivariate analyses.
Results of this study suggest potential modifiable targets of interventions for future research to help American Indians quit smoking: (1) improved delivery of behavioral interventions to increase the intensity of smoking cessation treatment; (2) promotion and adoption of complete home smoking bans; and (3) education to increase awareness of the benefits of NRT.
美国中西部上地区的美洲印第安人社区的吸烟率尤其高。
评估在使用尼古丁替代疗法 (NRT) 辅助的戒烟尝试中，美国中西部上地区基于人群的美洲印第安人群体中戒烟的预测因素。
本研究使用了一项吸烟者使用尼古丁替代疗法（NRT）辅助戒烟的队列研究的亚组样本，该研究中的美国印第安成年人（n = 291，响应率 = 55.4%）。符合条件的参与者在 2005 年 7 月至 2006 年 9 月期间通过明尼苏达州医疗保健计划（例如医疗补助）开了 NRT 处方。行政记录和随访调查数据用于评估 NRT 配药日期后大约 8 个月的结果。本分析于 2009-2010 年进行。
约 33%的试图戒烟的美国印第安受访者报告完全禁止在家中吸烟。在单变量和多变量分析中，采用完全家庭禁烟和更多感知到 NRT 的优势与 7 天的吸烟戒断呈横断面相关。与之前的研究一致，年龄较大是 7 天戒断的重要预测因素。过去一年有临床医生诊断的焦虑病史与未经调整的分析中 7 天不吸烟的可能性降低有关，但在多变量分析中不显著。
这项研究的结果表明，未来的研究可以针对可能改变的干预目标，帮助美洲印第安人戒烟：（1）改善行为干预措施的提供，以提高戒烟治疗的强度；（2）促进和采用完全家庭禁烟；（3）开展教育活动，提高对 NRT 益处的认识。
