Abstract Background High consumption of sugar-sweetened beverages (SSB) is a global health concern. Additionally, sugar-sweetened beverage (SSB) consumption is disproportionately high among adolescents and adults in rural Appalachia. The primary study objective is to determine the intervention effects of Kids SIP smart ER on students’ SSB consumption. Secondary objectives focus on caregivers’ SSB consumption and secondary student and caregiver outcomes e. g, body mass index (BMI), quality of life (QOL). Methods This Type 1 hybrid, cluster randomized controlled trial includes 12 Appalachian middle schools (6 randomized to Kids SIP smart ER and 6 to control). Kids SIP smart ER is a 6-month, 12 lesson, multi-level, school-based, behavior and health literacy program aimed at reducing SSB among 7th grade middle school students. The program also incorporates a two-way text message strategy for caregivers. In this primary prevention intervention, all 7th grade students and their caregivers from participating schools were eligible to participate, regardless of baseline SSB consumption. Validated instruments were used to assess SSB behaviors and QOL. Height and weight were objectively measured in students and self-reported by caregivers. Analyses included modified two-part models with time fixed effects that controlled for relevant demographics and included school cluster robust standard errors. Results Of the 526 students and 220 caregivers, mean (SD) ages were 12. 7 (0. 5) and 40. 6 (6. 7) years, respectively. Students were 55% female. Caregivers were mostly female (95%) and White (93%) ; 25% had a high school education or less and 33% had an annual household income less than 50, 000. Regardless of SSB intake at baseline and relative to control participants, SSB significantly decreased among students [-7. 2 ounces/day (95% CI = -10. 7, -3. 7) ; p 24 SSB ounces/day at baseline (i. e. , high consumers), the ES increased to 0. 45 and 0. 95, respectively. There were no significant effects for student or caregiver QOL indicators or objectively measured student BMI; however, caregiver self-reported BMI significantly decreased in the intervention versus control schools (p = 0. 001). Conclusions Kids SIP smart ER was effective at reducing SSB consumption among students and their caregivers in the rural, medically underserved Appalachian region. Importantly, SSB effects were even stronger among students and caregivers who were high consumers at baseline. Trial registration Clincialtrials. gov: NCT03740113.
