本综述探讨了目前不想戒烟的吸烟者减少吸烟是否（a）破坏或促进未来戒烟或（B）降低患吸烟相关疾病的风险。系统的计算机搜索和其他方法找到19项研究检查减少和随后的停止和10项研究检查减少和疾病的风险。由于方法和结果的异质性，无法进行荟萃分析。19项研究中没有一项发现减量会破坏未来的戒烟，16项发现减量与未来更大的戒烟相关，包括减量与非减量的两项随机试验。10项关于疾病风险的试验发现了相互矛盾的结果，没有一项是适当的测试。我们的结论是：（a）减少吸烟会增加未来戒烟的可能性，（B）减少吸烟是否会降低吸烟相关疾病的风险尚未得到充分的检验。
This review examines whether reduction in smoking among smokers not currently interested in quitting (a) undermines or promotes future smoking cessation or (b) decreases the risks of developing smoking-related diseases. Systematic computer searches and other methods located 19 studies examining reduction and subsequent cessation and 10 studies examining reduction and disease risk. Because of the heterogeneity of methods and results, a metaanalysis could not be undertaken. None of 19 studies found that reduction undermined future cessation, and 16 found that reduction was associated with greater future cessation, including the two randomized trials of reduction versus nonreduction. The 10 trials of disease risk found conflicting results, and none was an adequate test. We conclude that (a) smoking reduction increases the probability of future cessation and (b) whether smoking reduction decreases the risks of smoking-related diseases has not been adequately tested.
