There is inconsistent evidence that behavioural support to promote smoking reduction is effective at increasing smoking cessation. We examined the effectiveness of brief physician advice together with four very brief telephone calls in promoting smoking cessation among Chinese men via reduction compared with equivalent advice on diet and exercise.
A two-group pragmatic randomized controlled trial.
Male patients attending the Endocrinology and Acupuncture out-patient clinics of a general hospital in Beijing, China.
Physicians advised participants allocated to the smoking-reduction intervention (SRI, n = 181) group to reduce smoking to at least half of their current consumption within 1 month at baseline. At follow-up, a telephone counsellor repeated this advice if the participant had not reduced their cigarette consumption. Participants who had reduced consumption were encouraged to quit smoking. Physicians gave participants in the exercise and diet advice (EDA, n = 188) control group brief advice about physical activity and healthy diet at baseline, and a telephone counsellor reinforced this at each follow-up interview. Both groups had one face-to-face interview at baseline plus five telephone interviews and interventions (approximately 1 minute each) at 1 week and 1-, 3-, 6- and 12-month follow-up.
The primary outcome was self-reported 6-month prolonged abstinence rate at 12-month follow-up interview.
By intention-to-treat, the self-reported 6-month prolonged abstinence rate at 12-month follow-up in the SRI groups (19 quitters, 15.7%) was higher, but not significantly, than the EDA control group (10 quitters, 7.8%), and the adjusted odds ratio (OR) and 95% confidence interval (CI) was 2.26 (0.97-5.26), P = 0.062. The self-reported 7-day point prevalence quit rate (secondary outcome) in the SRI group was significantly higher than the control group at each follow-up interview (at 12-month follow-up: 13.3 versus 6.9%, OR (95% CI) = 2.09 (1.01, 4.34), P = 0.049).
A very brief, proactive and low-cost smoking-reduction intervention without medications for Chinese male smokers with no intention to quit appears to increase smoking abstinence.
有不一致的证据表明，行为支持以促进减少吸烟可有效增加戒烟率。我们研究了在通过减少吸烟来促进戒烟方面，与饮食和运动方面的等效建议相比，简短的医生建议加上四次非常简短的电话对中国男性的有效性。
两组实用随机对照试验。
在中国北京一家综合医院的内分泌科和针灸门诊就诊的男性患者。
将参与者分配到吸烟减少干预（SRI，n=181）组的医生建议他们在基线时的 1 个月内将吸烟量减少到当前吸烟量的至少一半。在随访时，如果参与者没有减少吸烟量，电话顾问会重复此建议。鼓励减少吸烟量的参与者戒烟。给饮食和运动建议（EDA，n=188）对照组的参与者在基线时提供关于体育活动和健康饮食的简短建议，电话顾问在每次随访访谈时都会加强这方面的建议。两组在基线时均进行一次面对面访谈，然后在 1 周和 1、3、6 和 12 个月随访时进行五次电话访谈和干预（每次约 1 分钟）。
主要结果是在 12 个月随访时通过自我报告的 6 个月持续戒烟率。
根据意向治疗原则，SRI 组（19 名戒烟者，15.7%）的自我报告的 12 个月随访时 6 个月持续戒烟率较高，但无统计学意义，而 EDA 对照组（10 名戒烟者，7.8%），调整后的比值比（OR）和 95%置信区间（CI）为 2.26（0.97-5.26），P=0.062。SRI 组在每次随访时的自我报告的 7 天点流行戒烟率（次要结果）均显著高于对照组（在 12 个月随访时：13.3%对 6.9%，OR（95%CI）=2.09（1.01，4.34），P=0.049）。
对于没有戒烟意向的中国男性吸烟者，一种非常简短、积极主动且低成本的不使用药物的吸烟减少干预措施似乎可以增加戒烟率。
