比较定制和非定制的戒烟短信：一项关于青少年和年轻成人吸烟者的随机对照试验
2014/03/06
摘要
本研究旨在比较高频率发送的定制短信和非定制短信对戒烟的影响。从2007年2月到2009年8月，2030位15～25岁的互联网戒烟项目（提供可选性短信服务）使用者纳入研究，他们相继随机分为接收定制短信组或非定制短信组。在随访的12个月中，记录使用者自报30天不吸烟的情况。定制组和非定制组的回应率分别为36.3%和38.1%。我们分析了整个研究人群，包括那些选择短信服务的人群(n = 1619)。在多项缺失数据干扰的意向治疗分析中，定制组与非定制组相比，30天不吸烟的比值比为1.28（95%可信区间为0.91-2.08）。当分析限定于选择短信服务的受试者时，相应的比值比为1.45（95%可信区间为1.01-2.08）。在限定分析中，定制短信组比非定制短信组的长期戒烟率更高，提示定制和高频短信可增加年轻吸烟者的戒烟率。

Abstract
The aim was to compare the effectiveness of untailored text messages for smoking cessation to tailored text messages delivered at a higher frequency. From February 2007 to August 2009, 2030 users of an internet-based smoking cessation program with optional text message support aged 15-25 years were consecutively randomized to versions of the program that offered either tailored or untailored text messages. Thirty-day point abstinence from smoking was measured self-reportedly at 12-months follow-up. Response rates were 36.3% and 38.1% in the tailored and untailored group, respectively. We analyzed the entire study population, as well as those opting for text messages (n = 1619). In intention-to-treat analysis with multiple imputation of missing data, the odds ratio for 30-day point abstinence was 1.28 (95% CI 0.91-2.08) for the tailored compared with untailored messages. When restricting the analysis to those who had chosen to receive text messages, the corresponding odds ratio was 1.45 (95% CI 1.01-2.08). The higher long-term quit rates in the group receiving the tailored text messages compared with untailored text messages in the restricted analysis indicated that tailoring and higher frequency of text messages increases quit rates among young smokers.
