SSB, sugar-sweetened beverage; k, number of studies.

Significant time effect only or significant reduction of SSB consumption in both the experimental and the control group.

^†

Significant reduction of SSB consumption in half of the experimental group (peer advocates) and significant increase of SSB consumption in the other half of the experimental group (non-peer advocates).

^‡

Significant reduction of SSB consumption in half of the experimental group and no significant reduction of SSB consumption in the other half of the experimental group.

^§

Significant reduction in frequency of cola consumption, but significant increases in volume of SBB consumed and in percentage of adolescents who consume SSB.
