尼古丁替代治疗在早期成功戒烟中的作用
2010/02/23
前言:尼古丁替代治疗(NRT)是一种有效的戒烟手段,尽管尼古丁可在非处方药柜台购买,但在戒烟中的使用尚不广泛。本试验研究与其它措施相比,早期自愿采用NRT是否能预测较好的自我戒断率。
方法:共纳入99例期望在近期戒烟的成人吸烟者,受试者在干预前存在10天以上的基线期。研究中既未推荐也不排斥NRT的使用。戒断定义为生化检测呼吸气CO水平小于4 ppm。初始戒断以下面2种方法表示:(a)任何一天的基线戒断;(b)基线戒断总天数。对NRT 使用、人口统计学、自我效能、动机准备及尼古丁依赖的预测值进行检测。
结果:较高的自我效能能预测初始戒断。NRT使用是最为一致的预测因子。在第1天就使用NRT的受试者,基线状态下至少戒断1天的OR比未使用NRT受试者高16.8倍。自我效能及任何基线NRT使用是引起戒断总天数差异的主要原因,总体模型能解释其中29%的变异(P<0.001)。NRT使用的基线天数总和与第1天使用NRT也能预测戒断总天数。
讨论:基于NRT能有效帮助戒烟,但使用不普及。我们研究结果支持以下观点:有必要采取措施鼓励吸烟者使用NRT戒烟。

The role of nicotine replacement therapy in early quitting success.
Amodei N, Lamb RJ.
INTRODUCTION: Nicotine replacement therapy (NRT) is an effective but underutilized smoking cessation aid despite being available over the counter. This exploratory study examined whether voluntary early use of NRT predicted cessation in a self-initiated quit attempt better than other commonly studied variables.
METHODS: Data were collected from 99 adult smokers desiring to quit smoking in the near future over a 10-day baseline period prior to the implementation of a contingency management intervention. NRT use was neither encouraged nor discouraged during the study. Initial abstinence, biochemically verified using a criterion of CO level <4 ppm, was conceptualized in 2 ways: (a) any day of baseline abstinence and (b) the sum of baseline days abstinent. We examined the predictive value of NRT use as well as demographics, self-efficacy, motivational readiness, and nicotine dependence.
RESULTS: While greater self-efficacy was predictive of initial abstinence, NRT use was the most consistent predictor. The odds of abstaining at least 1 day during baseline were 16.8 times greater for those who used NRT on Day 1 than nonusers. Self-efficacy and "any baseline NRT use" contributed significant amounts of variance to the "sum of days abstinent," with the overall model explaining 29% of the variance (p < .001). The sum of baseline days of NRT use and use of NRT on Day 1 also predicted the "sum of days abstinent."
DISCUSSION: Given NRT’s effectiveness, but underutilization in real-world settings, the data support the need for interventions or strategies encouraging people to use NRT in their quit attempts.
