Outcome Measures

Primary Outcomes (2)

  • Change in water consumption of school children (from baseline to post-intervention and follow-up)

    baseline, end of intervention (after one school year, 9 months), follow-up (after two school years, 21 months)

  • Change of attitude of school children towards drinking water (from baseline to post-intervention and follow-up)

    preference for water and sugar-sweetened beverages (measured as agreement to various statements regarding water and sugar-sweetened beverage consumption with 5 likert-scale answer categories: yes, that's right; yes, mostly; no, mostly not; no, not true; I don't know)

  • Change in breakfast consumption of school children (from baseline to post-intervention and follow-up)

    baseline, end of intervention (after one school year, 9 months), follow-up (after two school years, 21 months)

Study Arms (2)

Intervention group "Wasserschulen"

EXPERIMENTAL

Schools receive refillable drinking bottles for all school children and drying racks for each classroom. Schools receive special project educational material and informational material and one training session for teachers. The intervention will be implemented during one school year (2018/2019), but schools can use the material and bottles also after ending of the intervention period.
