Obesity: Technology-Supported Multicomponent Coaching or Counseling Interventions To Maintain Weight Loss
Summary of CPSTF Finding
CPSTF Finding and Rationale Statement
About The Systematic Review
The review was conducted on behalf of the CPSTF by a team of specialists in systematic review methods, and in research, practice, and policy related to obesity prevention and control.
Summary of Results
Summary of Economic Evidence
- Home and community settings
- Interventions delivered by counselors, therapists, or health coaches
- Assorted technologies (e.g., websites, email, interactive TV modalities)
- Does the type of technology and whether it is mobile make a difference?
- Are technology-based interventions as effective in subpopulations? Does effectiveness vary by age, cultural, SES, gender, race, or ethnicity?
- Is there an interaction between subpopulations (e.g., cultural, age) and type of technology (e.g. computer, mobile device)?
- How does provider training or credentialing affect services to clients?
- Are clients and providers more likely to engage if technical support or training on computer applications are provided?
- All of the included studies used randomized controlled trials.
- Studies were conducted in the U.S. and targeted adults.
When starting an effectiveness review, the systematic review team develops an analytic framework. The analytic framework illustrates how the intervention approach is thought to affect public health. It guides the search for evidence and may be used to summarize the evidence collected. The analytic framework often includes intermediate outcomes, potential effect modifiers, potential harms, and potential additional benefits.

The review reflects systematic searches of four computerized databases (Medline, CINAHL, EMBASE, and PsycINFO). The search combined terms related to technology (e.g., computer, Internet, videoconference) with terms related to weight, physical activity, diet outcomes, health education/promotion, and overweight. The specific search terms used are shown below.
The reference lists from search-identified studies, as well as those of prior literature reviews and systematic reviews, also were used to identify relevant articles. Experts in interventions that address obesity and/or screen time (i.e., time spent watching TV, videotapes, or DVDs; playing video or computer games; and surfing the Internet) were consulted for additional citations.
Searches were limited to literature published in English-language journals between 1966 and the June 2008. To be considered for inclusion in the review of effectiveness, studies had to (1) be primary investigations of interventions rather than guidelines or reviews, and (2) provide data on either weight-related outcomes, physical activity, or nutrition.
Studies were excluded if outcomes were collected in pregnant or post-partum populations, or the study specifically recruited patients with the following medical conditions: end stage disease (e.g., renal), cancer survivor, bulimic, anorexic, or psychiatric disorder. Also excluded were studies that focused specifically on diabetic monitoring (as opposed to nutrition, physical activity, or obesity interventions targeting people with diabetes).

For the economic review, the effectiveness review search was expanded to include additional databases: EconLit, SSCI, JSTOR, Google Scholar, and repositories of health economics research at selected universities and institutes, including the University of York.
The economic search combined economic-specific keywords such as cost, cost-benefit, cost-effectiveness, and cost-utility with the effectiveness search terms.
Considerations for Implementation
- Technology supported counseling may offer increased access for people living in remote areas, people who cannot travel easily, or people with unusual work schedules. They also allow anonymity for those who prefer it, and can be available 24 hours a day.
- Developing technology-supported interventions requires an initial investment in computer hardware, software, and application design.
- Participants will need access to a computer or other technology.
- Practitioners and participants may require training with new technology.
- It may be difficult to keep up with rapid changes in technology (data security).
