To examine indicators of nicotine dependence in a national sample of Aboriginal and Torres Strait Islander daily smokers and their association with sustaining a quit attempt for at least 1 month, and to make comparisons with a national sample of Australian daily smokers.
DESIGN, SETTING AND PARTICIPANTS: The Talking About The Smokes project used a quota sampling design to recruit 1392 daily smokers from communities served by 34 Aboriginal community-controlled health services and one community in the Torres Strait from April 2012 to October 2013. These were compared with 1010 daily smokers from the general Australian population surveyed by the International Tobacco Control Policy Evaluation Project from September 2011 to February 2012.
Cigarettes per day (CPD), time to first cigarette, Heaviness of Smoking Index (HSI), other indicators of dependence, and whether smokers had ever sustained a quit attempt for at least 1 month.
There was little difference in the mean HSI scores for Aboriginal and Torres Strait Islander and other Australian daily smokers. A higher proportion of Aboriginal and Torres Strait Islander daily smokers smoked ≤ 10 CPD (40% v 33.4%), but more also smoked their first cigarette within 30 minutes of waking (75% v 64.6%). Lower proportions of Aboriginal and Torres Strait Islander smokers reported having strong urges to smoke at least several times a day (51% v 60.7%) or that it would be very hard to quit (39% v 47.9%). Most Aboriginal and Torres Strait Islander smokers reported experiencing difficulties during their most recent quit attempt. All indicators of dependence, except CPD and strong urges, were positively associated with not having made a sustained quit attempt. Reported difficulties during the most recent quit attempt were more strongly associated with being unable to sustain quit attempts than were traditional measures of dependence.
Aboriginal and Torres Strait Islander smokers' experiences of past attempts to quit may be more useful than conventional indicators of nicotine dependence in understanding their dependence.
在澳大利亚原住民和托雷斯海峡岛民每日吸烟者的全国样本中，研究尼古丁依赖的指标，以及这些指标与维持至少 1 个月戒烟尝试的关系，并与澳大利亚全国每日吸烟者的样本进行比较。
设计、地点和参与者：“谈论吸烟”项目采用配额抽样设计，于 2012 年 4 月至 2013 年 10 月从 34 个由原住民社区控制的卫生服务机构和托雷斯海峡的一个社区服务的社区中招募了 1392 名每日吸烟者，与 2011 年 9 月至 2012 年 2 月期间由国际烟草控制政策评估项目在澳大利亚普通人群中调查的 1010 名每日吸烟者进行了比较。
每日吸烟量（CPD）、首次吸烟时间、吸烟严重程度指数（HSI）、其他依赖指标，以及吸烟者是否曾有过至少 1 个月的戒烟尝试。
原住民和托雷斯海峡岛民与其他澳大利亚每日吸烟者的 HSI 评分均值差异不大。较高比例的原住民和托雷斯海峡岛民每日吸烟者吸烟量≤10 支（40%比 33.4%），但更多的人在醒来后 30 分钟内就开始吸烟（75%比 64.6%）。较少比例的原住民和托雷斯海峡岛民吸烟者报告每天至少有几次强烈的吸烟欲望（51%比 60.7%）或认为戒烟非常困难（39%比 47.9%）。大多数原住民和托雷斯海峡岛民吸烟者报告说，在最近一次戒烟尝试中遇到了困难。除 CPD 和强烈的吸烟欲望外，所有依赖指标都与未进行持续戒烟尝试呈正相关。在最近一次戒烟尝试中报告的困难与无法持续戒烟尝试的相关性比传统的依赖指标更强。
原住民和托雷斯海峡岛民吸烟者过去戒烟尝试的经历可能比尼古丁依赖的传统指标更能帮助我们理解他们的依赖程度。
