iSIPsmarter: An RCT Evaluating the Efficacy of a Technology-Based Intervention to Reduce Sugary Drinks in Rural Appalachia

Summary

The proposed randomized controlled trial (RCT) is guided by the RE-AIM (i.e. reach, efficacy, adoption, implementation, maintenance) framework and targets 244 adults from rural Appalachia. The overall goal is to examine the efficacy of iSIPsmarter in a 2 group \[iSIPsmarter vs. static Patient Education (PE) website\] by 4 assessment (Pre, 3-, 6- and 18-month follow-up) design. It is hypothesized that iSIPsmarter will be more efficacious at reducing SSB consumption than a PE website at post assessment.

Conditions

• Diet Habit
• Sugar-Sweetened Beverages

Interventions

BEHAVIORAL

iSIPsmarter

iSIPsmarter is a technology-based behavioral and health literacy intervention. It is comprised of six Internet-delivered Cores, an integrated short message service (SMS) strategy to engage users in tracking SSB behaviors, and the incorporation of a cellular enabled scale for in-home weight tracking. Participants will be prompted (via email or text) to self-monitor their sugar-sweetened beverage intake. iSIPsmarter is a highly interactive, structured, and self-guided program that uses strategies previously proven to promote behavior change. iSIPsmarter also incorporates a stepped care approach to re-engage users who struggle to complete components.

BEHAVIORAL

Patient Education (PE)

he PE website will include scientifically accurate information that is typical of nutrition education websites and will include information about SSB recommendations, types of SSB and portion size, SSB-related health risks, energy balance information, identifying personal motivators and barriers to reducing SSB intake, interpreting SSB nutrition labels, and recognizing media influences and misclaims in SSB advertisements, as well as printable forms to track SSB and weight. Unlike iSIPsmarter, the content will not be tailored and will be presented all at once.
