Bottom Line: Here we evaluated the effect of a combined school- and community-based intervention aimed at reducing children's SSB consumption by promoting the intake of water.Significant positive intervention effects were found for average SSB consumption (B -0.19 litres, 95% CI -0.28;-0.10; parent report), average SSB servings (B -0.54 servings, 95% CI -0.82;-0.26; parent report) and bringing SSB to school (OR 0.51, 95% CI 0.36;0.72; observation report).This study supports the effectiveness of the water campaign intervention in reducing children's SSB consumption.

ABSTRACT

Background: Since sugar-sweetened beverages (SSB) may contribute to the development of overweight in children, effective interventions to reduce their consumption are needed. Here we evaluated the effect of a combined school- and community-based intervention aimed at reducing children's SSB consumption by promoting the intake of water. Favourable intervention effects on children's SSB consumption were hypothesized.

Methods: In 2011-2012, a controlled trial was conducted among four primary schools, comprising 1288 children aged 6-12 years who lived in multi-ethnic, socially deprived neighbourhoods in Rotterdam, the Netherlands. Intervention schools adopted the 'water campaign', an intervention developed using social marketing. Control schools continued with their regular health promotion programme. Primary outcome was children's SSB consumption, measured using parent and child questionnaires and through observations at school, both at baseline and after one year of intervention.

Results: Significant positive intervention effects were found for average SSB consumption (B -0.19 litres, 95% CI -0.28;-0.10; parent report), average SSB servings (B -0.54 servings, 95% CI -0.82;-0.26; parent report) and bringing SSB to school (OR 0.51, 95% CI 0.36;0.72; observation report).

Conclusions: This study supports the effectiveness of the water campaign intervention in reducing children's SSB consumption. Further studies are needed to replicate our findings.

Figure 2: Overview of the data collection.

Mentions: Since the intervention was implemented over two school years, it was necessary to combine the baseline measurements for the child questionnaire and the observations. Children in grades 6 and 7 completed the baseline questionnaire in April 2011; children in grade 5 (and children in grades 6 and 7 who were absent during the April measurement) completed their baseline questionnaire in September 2011. Children in grades 3-7 were observed for baseline measurement in April 2011 and children in grade 2 (and children grades 3-7 who were absent during the April measurement) were observed for baseline measurement in September 2011. Hypothetically, the fact that we used a combined baseline could have led to underestimation of effect because some children had already been exposed to the intervention. However, when we repeated the analyses using only the April 2011 data as baseline measurement we found similar results (data not shown). An overview of the data collection is presented in FigureĀ 2.
