简要总结
CHAT is an internet-based weight loss research program designed for women with overweight or obesity who want to lose weight through dietary change and increased physical activity. Participants will be randomized into a group-based online program who meet via a text chat or a video chat.
详细描述
The overall goal of this project is to determine whether weight losses can be improved if visual chat and electronic smart scales are added to an established 6-month online weight loss program. The primary aim is to assess weight change differences between subjects randomized to receive an Internet program alone (with text chat; INTERNET) vs. an Internet program with visual chat and electronic scales (VIDEO INTERNET). A secondary aim is to evaluate differences in social support experienced by subjects in both conditions. Overweight and obese adults (n=40) at two study sites (UVM and the University of South Carolina) will be randomly assigned to Internet (n=20) or Video Internet (n=20). All participants will receive the same 24 week web-based group weight control program which features synchronous facilitated chats and online behavioral tools. The only difference will be the delivery of the chat (text vs. visual) and the electronic smart scales given to the VIDEO INTERNET group. Assessments will be conducted at 0, 2 and 6 months and will include measures of body weight, treatment engagement (e.g., attendance, self-monitoring, website utilization), social support and treatment satisfaction.

研究组 & 干预措施
Behavioral Weight Loss + Text chat
Internet delivery of a behavioral weight control program via text in a group format facilitated by an experienced registered dietitian. Participants will have access to study materials including behavioral weight loss lessons on the study's website. Participants will weigh themselves daily and report their weight privately (data will only be accessible by research personnel) on the study website.
干预措施: Behavioral Weight Loss + Text (Behavioral)
Behavioral Weight Loss + Video chat
Internet delivery of a behavioral weight control program via video in a group format facilitated by an experienced registered dietitian. Participants will have access to study materials including behavioral weight loss lessons on the study's website. Participants will be given smart scales to weigh daily, and weight will be transmitted to a secure website accessible only by research personnel.
干预措施: Behavioral Weight Loss + Video (Behavioral)
结局指标
主要结局
Weight loss from baseline
时间窗: baseline, 2 months, 6 months
The investigators will assess weight change differences between subjects randomized to receive an internet program alone with text chat vs. an internet program with visual chat and bodytrace smart scales. Weight will be assessed at baseline, 2 months after intervention begins, and at the end of intervention using a calibrated digital scale (Tanita, WB800S) with subjects in street clothes, without shoes.
次要结局
- Self monitoring weight(6 months)
- Attendance at chat(6 months)
- Self monitoring dietary intake(6 months)
