Measuring Healthy Beverage Intake and Exploring Opportunities to Improve Beverage Consumption

Background: Poor beverage consumption habits pose significant health concerns. Delivering health behavior change interventions via social media is an emerging area of health research and may provide a promising way to minimize barriers such as cost, intervention delivery time, and access. However, there is limited research on online social support health behavior change delivered through Instagram. Objectives: 1) Assess the validity and reproducibility of the updated BEVQ-15, a beverage intake questionnaire; 2) Review the current literature on the availability and effectiveness of mobile phone interventions targeting sugar-sweetened beverage (SSB) consumption; and 3) Use the updated BEVQ-15 to conduct the Healthy Beverage Habits pilot study, which is an online social networking worksite intervention aimed at improving Healthy Beverage Index (HBI) scores. Methods: The Healthy Beverage Habits study was an online randomized controlled pilot trial with an 8-week intervention and a 4-week maintenance period delivered through Instagram. The materials were adapted from the in-person SIPsmartER SSB reduction intervention. Data analysis included RM-ANOVAs to test for differences in beverage intake between the Instagram intervention group and the E-mail control group. Results: For the Healthy Beverage Habits trial, no significant between group over time differences were found. However, the Instagram group demonstrated a significant reduction in total beverage kcal (mean difference±SE=-156±48; p=0.049), and increase in total HBI scores (mean difference±SE= 11.9±2.3; p=0.025) from baseline to the end of the maintenance period. No within group differences were demonstrated for the E-mail control group over the intervention or maintenance period. The study retention rate was 38%, with 39 participants initially enrolled and 15 participants completing all study visits through maintenance. Results for the validity and reproducibility of the updated BEVQ-15 and a review of the availability and effectiveness of mobile phone interventions targeting SSB consumption are presented. Conclusions: Mobile phone-delivered interventions may be a promising method for improving beverage intake quality. Technologically-based interventions targeting beverage consumption should consider utilizing multiple forms of mobile-phone contact methods. The preliminary findings from the Healthy Beverage Habits trial highlight the need for more rigorous studies that determine which technology and intervention components are most effective for mobile-delivered beverage consumption interventions.
