To compare the effectiveness of quitting immediately and cutting down to quit in promoting smoking abstinence among smokers in an outpatient clinic.
A total of 100 subjects were randomized into two groups, 50 in the quit immediately group, who received an intervention on abruptly quitting, and 50 in the cut down to quit group, who received an intervention on gradual reduction. All subjects were followed up at 6 and 12 months via telephone. The intention-to-treat principle was used.
At the 6-month follow-up, the self-reported quit rate of subjects in the quit immediately group was significantly higher than in the cut down to quit group (18.0% vs. 4.0%, p = 0.04). However, this difference was not significant at the 12-month follow-up (12.0% vs. 4.0%, p = 0.16).
These data suggest that quitting immediately might be more effective than cutting down to quit at 6 months but not at 12 months.
It is crucial to allow smokers to select quitting immediately or reducing the number of cigarettes smoked. Further studies are warranted to compare the effectiveness of various approaches for achieving smoking abstinence.
比较门诊吸烟者立即戒烟与逐渐减少吸烟量戒烟的效果。
共纳入 100 名研究对象，随机分为两组，立即戒烟组 50 人，接受立即完全戒烟的干预措施；逐渐减少吸烟量组 50 人，接受逐渐减少吸烟量的干预措施。所有研究对象均通过电话在 6 个月和 12 个月时进行随访。采用意向治疗原则。
在 6 个月的随访中，立即戒烟组的自我报告戒烟率明显高于逐渐减少吸烟量组（18.0%比 4.0%，p=0.04）。然而，在 12 个月的随访中，这种差异无统计学意义（12.0%比 4.0%，p=0.16）。
这些数据表明，立即戒烟在 6 个月时可能比逐渐减少吸烟量更有效，但在 12 个月时则不然。
允许吸烟者选择立即戒烟或减少吸烟量至关重要。需要进一步研究来比较实现戒烟的各种方法的效果。
