香港于2007年1月1日实施新的无烟法例，禁止在大部分室内工作间及公众地方吸烟。西方国家的经验显示，禁烟法例实施后，戒烟服务的需求会增加，但东南亚国家并没有就此问题进行有系统的研究。本研究旨在探讨无烟立法在促进戒烟通过本地quitline的影响。本研究报告的电话调查结果，使用中断的时间序列分析。我们于2005年8月至2007年9月期间为市民开设免费戒烟热线。本研究测量了无烟立法实施前后电话接听和处理数量的百分比变化，并对无烟立法实施前（2006年1月至9月）和实施后（2007年1月至9月）9个月的戒烟热线进行了评估。最初阶段的呼叫率为每月27.6，而立法后为每月34.9，增加了26%。基于间断时间序列模型，无烟立法的最初影响是增加每周接收和处理的电话数量（p < .001），但影响是暂时的，并在6个月内恶化。新无烟立法的实施对促进香港戒烟热线的使用有短期影响。有系统和长期的控烟运动应与无烟立法相结合，以促进和维持吸烟者对戒烟的兴趣。
New smoke-free legislation implemented in Hong Kong on 1 January 2007, prohibited smoking in the vast majority of indoor workplaces and public places. Experiences of western countries indicated that the need for smoking cessation services would increase after enactment of the smoke-free legislation, but no systematic study of this issue has been undertaken in Southeast Asia. The present study aimed to examine the impact of smoke-free legislation in promoting smoking cessation through a local quitline.The present study reports the results of a telephone survey using interrupted time-series analysis. We operated a toll-free smoking cessation hotline (quitline) for the general public from August 2005 to September 2007. The present study measured the percent change in the number of telephone calls received and handled before and after the smoke-free legislation.We evaluated the quitline for 9-month periods before (January-September 2006) and after (January-September 2007) the smoke-free legislation was implemented. The call rate in the initial period was 27.6 per month compared with 34.9 per month after enactment of the legislation, a 26% increase. Based on interrupted time-series models, the initial impact of the smoke-free legislation was to increase the number of telephone calls received and handled per week (p < .001), but the impact was temporal and deteriorated within 6 months.Implementation of the new smoke-free legislation had a short-term effect in promoting the utilization of a smoking cessation quitline in Hong Kong. A systematic and long-term tobacco control campaign should be combined with smoke-free legislation to promote and sustain smokers' interests in smoking cessation.
