Summary
A digital intervention effectively reduced sugar-sweetened beverage (SSB) consumption in Appalachian adults. This method also led to significant weight reduction, showing promise for public health initiatives.
Area of Science:
- Public Health
- Behavioral Science
- Digital Health Interventions
Background:
- Reducing sugar-sweetened beverage (SSB) consumption is a global public health priority.
- Appalachia exhibits significant disparities in SSB consumption patterns.
Purpose of the Study:
- To measure the efficacy of a digital behavioral intervention in reducing SSB intake.
- To explore the intervention's impact on weight and quality of life (QOL).
Main Methods:
- A two-group randomized-controlled trial (RCT) involved adults in Appalachia.
- Participants received either a digital intervention or a static education website.
- SSB intake, QOL, and weight were assessed at baseline, 9 weeks, and 6 months.
Main Results:
- Digital intervention participants showed significant reductions in SSB consumption at 9 weeks and 6 months.
- The digital intervention group experienced a significant reduction in body weight at 6 months.
- High engagement and retention rates were observed in the digital intervention group.
Conclusions:
- A digital behavioral intervention proved effective in reducing SSB consumption among Appalachian adults.
- The intervention demonstrated high engagement and retention, suggesting its potential for broader application.
- Further evaluation in populations with high SSB consumption is recommended.

Blinding is a commonly used method of not telling participants which treatment a subject is receiving. Blinding is a critical part of a randomized control trial or RCT. It reduces the bias that affects the results. In an RCT, blinding is used in the form of a placebo. A placebo effect occurs when untreated subjects falsely believe they have received the treatment and report improved symptoms. A placebo or a dummy treatment is administered to subjects to negate the bias caused by such an effect.

Sampling is a technique to select a portion (or subset) of the larger population and study that portion (the sample) to gain information about the population. Data are the result of sampling from a population. The sampling method ensures that samples are drawn without bias and accurately represent the population.
