The onset of type 2 diabetes mellitus can be prevented or delayed by lifestyle changes. Communication technologies such as a mobile phone can be used as a means of delivering these lifestyle changes.
The purposes of this analysis were to explore applicability of potential components of a mobile phone-based healthy lifestyle program and to understand motivators and barriers to continued engagement in a mobile phone healthy lifestyle program.
We conducted 6 focus groups (4 female and 2 male groups) in May and June 2010 with 35 focus group participants. The qualitative data were analyzed by 3 researchers using a qualitative description method in an ATLAS.ti software program. Inclusion criteria for enrollment in a focus group were as follows: (1) being aged from 30 to 69 years, (2) speaking and reading English, (3) having a sedentary lifestyle at work or during leisure time (screened by the Brief Physical Activity Survey questionnaire), and (4) having a body mass index (BMI) >25 kg/m(2) (Asian >23 kg/m(2)) based on self-reported weight and height or 5) having a self-reported prediabetic condition.
The mean age was 51 (SD 10.6) years; 54% (n = 19) were white; 71% (n = 25) used a mobile phone at least once a week during the last month prior to the study enrollment; and mean BMI was 32.5 (SD 6.5) kg/m(2). In the qualitative analyses, the following 4 major themes and their subthemes emerged: (1) real-time social support (real-time peer support from participants who are similarly engaged in a diet or physical activity program, and professional support from health care providers or a researcher), (2) tailoring of mobile phone programs (3) self-monitoring and motivation, and (4) potential barriers and sustainability of the program (fear of failing, age and mobile technologies, and loss of interest over time).
Participants from a wide range of age and racial groups expressed interest in a mobile phone-based lifestyle program. Such a program that incorporates the themes that we identified may be able to help motivate participants to increase their physical activity and to improve their diet.
2型糖尿病的发病可以通过改变生活方式来预防或延缓。诸如手机等通信技术可作为传递这些生活方式改变的一种手段。
本分析的目的是探讨基于手机的健康生活方式项目潜在组成部分的适用性，并了解持续参与手机健康生活方式项目的动机和障碍。
2010年5月和6月，我们对35名焦点小组参与者进行了6次焦点小组讨论（4个女性组和2个男性组）。3名研究人员使用定性描述方法在ATLAS.ti软件程序中对定性数据进行了分析。焦点小组参与者的纳入标准如下：（1）年龄在30至69岁之间；（2）会说和读英语；（3）工作或休闲时久坐不动（通过简短身体活动调查问卷筛选）；（4）根据自我报告的体重和身高，体重指数（BMI）>25kg/m²（亚洲人>23kg/m²）；或（5）自我报告有糖尿病前期状况。
平均年龄为51（标准差10.6）岁；54%（n = 19）为白人；71%（n = 25）在研究入组前的最后一个月至少每周使用一次手机；平均BMI为32.5（标准差6.5）kg/m²。在定性分析中，出现了以下4个主要主题及其子主题：（）实时社会支持（来自同样参与饮食或体育活动项目的参与者的实时同伴支持，以及来自医疗保健提供者或研究人员的专业支持）；（2）手机项目的定制；（3）自我监测和动机；以及（4）项目的潜在障碍和可持续性（害怕失败、年龄与移动技术，以及随着时间推移兴趣丧失）。
来自广泛年龄和种族群体的参与者对基于手机的生活方式项目表示出兴趣。这样一个纳入我们所确定主题的项目可能能够帮助激励参与者增加身体活动并改善饮食。
