This systematic review and meta-analysis evaluated the effects of interventions to reduce sugar sweetened beverage (SSB) consumption and increase water intake. It also examined the impact of behaviour change techniques in consumption patterns. Forty studies with 16,505 participants were analysed. Interventions significantly decreased SSB consumption in children by 76ml/d (p<0.01) and adolescents (-66ml/d, p=0.04), but not in adults (-13ml/d, p=0.16). Estimates of water intake were only possible in interventions in children and results indicated increases. For children, evidence suggests modelling/demonstrating the behaviour helped to reduce SSB intake, and home based interventions had greater effects than school based ones. The authors concluded that interventions – mainly via nutrition education/counselling- are moderately successful at reducing SSB and increasing water intake in children, but only small reductions have been achieved in adolescents and adults. As such, complementary strategies may be required to effectively curb free sugar intake in these groups.
