Reducing Sugar-sweetened Beverage Consumption in Overweight Adolescents (BASH)

August 8, 2012 updated by: Boston Children's Hospital

Reducing Sugar-Sweetened Beverage Consumption in Overweight Adolescents

The primary aim of this study is to examine the effect of a multi-component intervention, designed to reduce consumption of sugar-sweetened beverages, on weight gain, total energy intake, and diet quality in adolescents. The secondary aim is to evaluate whether outcomes of the intervention differ between adolescents for whom 100% fruit juice vs. other products (i.e., soda, fruit punch, lemonade, iced tea, coffee drinks, energy drinks, sports drinks) constitutes the primary source of sugar from beverages.

Detailed Description

We are partnering with community organizations (including high schools) in the greater Boston area and a major regional supermarket. Participants will be 240 high school students who drink at least 1 serving of sugar-sweetened beverage (including 100% fruit juices) per day and who have a BMI ≥ 85th percentile. They will be randomly assigned to an intervention or control group. The intervention, of 1-year duration, will target the home/family environment in combination with a behavioral intervention provided during brief check-in visits. The environment will be changed by delivering non-caloric beverages to the homes of adolescents who regularly consume sugar-sweetened beverages. Parents will be counseled by telephone to serve as role models in consuming non-caloric beverages. The behavioral intervention for the adolescents will include didactic and experiential components during the check-in visits. Study outcomes will be assessed at baseline, 1 year (end of intervention period), and 2 years (end of follow-up period).

Additional relevant material based on the original proposal (NIH grant application) is provided below:

Each outcome will be compared between groups using a general linear model, adjusted for baseline covariates that could affect body weight: sex, race, ethnicity (Hispanic vs non-Hispanic), household income, parents' education, BMI, beverage consumption (sugar-sweetened, artificially sweetened, unsweetened), energy intake (total, sugar-sweetened beverages, fruit juice), physical activity level, and daily television viewing. Each covariate will be tested for confounding, mediation, and interaction effects on the primary outcome. Stratum-specific estimates of the group difference will be constructed for any covariates showing significant interaction.
