    Objective: To test the effectiveness of a social network intervention (SNI) to improve children’s healthy drinking behaviours. Design: A three-arm cluster randomised control trial design was used. In the SNI, a subset of children were selected and trained as ‘influence agents’ to promote water consumption–as an alternative to sugar-sweetened beverages (SSB)–among their peers. In the active control condition, all children were simultaneously expos…

  • Promoting Water Consumption on a Caribbean Island

    Open AccessSaskia C M Franken, Crystal R Smit et al.ARTICLEInternational Journal of…2018

    Sugar-sweetened beverage (SSB) consumption and the associated childhood obesity are major concerns in the Caribbean, creating a need for interventions promoting water consumption as a healthy alternative. A social network-based intervention (SNI) was tested among Aruban children to increase their water consumption and behavioral intention to do so and, consequently, to decrease SSB consumption and the associated behavioral intention. In this stud…
