Little is known about the effectiveness of mobile apps in aiding smoking cessation or their validity for automated collection of data on smoking cessation outcomes.
We conducted a preliminary evaluation of SF28 (SF28 is the name of the app, short for SmokeFree28)-an app aimed at helping smokers to be smoke-free for 28 days.
Data on sociodemographic characteristics, smoking history, number of logins, and abstinence at each login were uploaded to a server from SF28 between August 2012 and August 2013. Users were included if they were aged 16 years or over, smoked cigarettes at the time of registration, had set a quit date, and used the app at least once on or after their quit date. Their characteristics were compared with data from a representative sample of smokers trying to stop smoking in England. The percentage of users recording 28 days of abstinence was compared with a value of 15% estimated for unaided quitting. Correlations were assessed between recorded abstinence for 28 days and well-established abstinence predictors.
A total of 1170 users met the inclusion criteria. Compared with smokers trying to quit in England, they had higher consumption, and were younger, more likely to be female, and had a non-manual rather than manual occupation. In total, 18.9% (95% CI 16.7-21.1) were recorded as being abstinent from smoking for 28 days or longer. The mean number of logins was 8.5 (SD 9.0). The proportion recording abstinence for 28 days or longer was higher in users who were older, in a non-manual occupation, and in those using a smoking cessation medication.
The recorded 28-day abstinence rates from the mobile app, SF28, suggest that it may help some smokers to stop smoking. Further evaluation by means of a randomized trial appears to be warranted.
关于移动应用程序在辅助戒烟方面的有效性或其自动收集戒烟结果数据的有效性，人们了解甚少。
我们对SF28（SF28是该应用程序的名称，即“28天无烟”的简称）进行了初步评估，这是一款旨在帮助吸烟者实现28天无烟的应用程序。
2012年8月至2013年8月期间，SF28将有关社会人口学特征、吸烟史、登录次数以及每次登录时的戒烟情况的数据上传至服务器。纳入的用户需年龄在16岁及以上，注册时吸烟，设定了戒烟日期，且在戒烟日期当天或之后至少使用过一次该应用程序。将他们的特征与英国试图戒烟的吸烟者代表性样本的数据进行比较。将记录到28天戒烟的用户百分比与估计的15%的自发戒烟成功率进行比较。评估28天戒烟记录与既定戒烟预测因素之间的相关性。
共有1170名用户符合纳入标准。与英国试图戒烟的吸烟者相比，他们的吸烟量更高，年龄更小，女性比例更高，且从事非体力而非体力职业。总共有18.9%（95%置信区间16.7 - 21.1）的用户记录到已戒烟28天或更长时间。平均登录次数为8.5次（标准差9.0）。年龄较大、从事非体力职业以及使用戒烟药物的用户中，记录到戒烟28天或更长时间的比例更高。
移动应用程序SF28记录的28天戒烟率表明，它可能有助于一些吸烟者戒烟。似乎有必要通过随机试验进行进一步评估。
