Official title
Reducing Added Sugar Intake on Sweetness Perception in Adolescents by Substituting Unsweetened Sparkling Water for Sugar Sweetened Beverages
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The study design is a prospective observational study in adolescents who are at risk for developing Type 2 Diabetes (T2D), to evaluate the effectiveness of sparkling water to reduce dietary intake of added sugars and thereby improve glycemia. Study data on consumption and the flavor profile of sparkling water will serve as a measure of acceptability. The study intervention will be to provide carbonated flavored sparkling water for 12 weeks to adolescents (and their families) who have a usual intake of 2 or more servings of sugar sweetened beverages (SSB) per day and are at a high risk for developing type 2 diabetes. Study measures will be obtained before and after the exposure to carbonated flavored sparkling water and each participant will serve as his/her own control. To encourage the participants to substitute the carbonated flavored sparkling water, study personnel will send them weekly iMessages through the Technology Assisted Dietary Assessment (TADA) app. In addition, investigators will monitor the participants' diet, using the TADA app, every two weeks, for 4 days. Study measurements will be obtained at baseline, before the intervention, during and at the end of the 12 week intervention. Objective: Determine the effect of reducing added sugars intake by substituting carbonated sparkling water on T2D risk in adolescents. Hypothesis: Adolescents who decrease consumption of SSB by substituting sparkling water will experience decreased blood glucose concentrations and increased insulin sensitivity during an oral glucose tolerance test and decreased glucose excursions during continued glucose monitoring, compared to those who do not decrease consumption of SSB.
