- Brief Summary
The purpose of this controlled intervention study is to evaluate the effectiveness of a school-based intervention aiming at increasing the water consumption in elementary school children. The intervention schools received refillable water bottles and drying racks for all school children as well as educational material. The focus of the intervention is the promotion of drinking tap water.
- Detailed Description
This pilot project, called "H2NOE-Wasserschulen" (Water Schools in Lower Austria), aims to increase the water consumption of school children in elementary schools, to raise awareness of water drinking in children, parents and school teachers and to promote water drinking in Lower Austria in general.
By increasing the consumption of water, the consumption of sugar-sweetened beverages may decrease and in the long run may have a positive impact on children's body weight and tooth status.
All intervention schools receive refillable water bottles for each school child and drying racks for each classroom. Furthermore, in each school an information session for all school teachers is held and the teachers receive prepared educational material. The control schools do not receive the water bottles nor the educational material.
For the study, the investigators recruited 22 intervention schools and 32 control schools. Outcomes will be measured by paper and pencil questionnaires of school children at third grade of participating elementary schools in Lower Austria and with online questionnaires of teachers at baseline, at the end of the intervention (after one school year/June 2019) and at the one-year follow-up (after two school years/June 2020).
For process evaluation outcomes, the investigators will carry out focus group discussions with a subsample of school children and teachers and include questions in the respective questionnaires for school children, teachers and school headmasters. Parents will have the possibility to give feedback online.

Group Intervention Description Intervention group "Wasserschulen" Wasserschulen 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.
- Primary Outcome Measures
Name Time Method Change of attitude of school children towards drinking water (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) 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 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) consumption of tap water, in number of glasses (with 1 glass defined as 200 mL) per day/ during school time (self-report)
- Secondary Outcome Measures
Name Time Method Change in beverage 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) consumption of tap water, mineral water, fruit- and herbal tea, milk and cacao, soft drinks (lemonade, cola and iced tea), juice and juice with water; in number of glasses (with 1 glass defined as 200 mL) for the last 24h
Change in food 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) consumption of fruit and berries; vegetables (raw or cooked); sweets, chocolate or ice-cream; soft drinks (lemonade, cola and iced tea); fast food (french fries, chicken nuggets, pizza, McDonald's, sausages); salty snacks (crisps, popcorn, salted pretzel sticks); frequency of consumption during a normal week, when thinking of the last weeks
Parameters of process evaluation (implementation reach) end of intervention (after one school year, 9 months) proportion of classes that implemented the intervention, information about intervention on the school homepage, number of interventional material distributed in school; by online questionnaire (all headmasters from intervention schools); extent of information for parents; by online questionnaire (all teachers from intervention schools)
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) frequency of eating breakfast during school days and on the weekend
Parameters of process evaluation (acceptance) end of intervention (after one school year, 9 months) focus group discussions with a subset of school children, teachers and school headmasters
Parameters of process evaluation (implementation dose) end of intervention (after one school year, 9 months) frequency of addressing the topic water during regular lessons, implementation of classroom rules for water drinking, extent of water bottle use of school children; by online questionnaire (all teachers from intervention schools); extent of water bottle use, by paper and pencil questionnaire (all school children from intervention schools); number of interventional material distributed in school; by online questionnaire (all headmasters from intervention schools)
Parameters of process evaluation (implementation fidelity) end of intervention (after one school year, 9 months) implementation of classroom rules for water drinking; extent of information for parents; by online questionnaire (all teachers from intervention schools)
