    Strategien zur Optimierung der Ernährung in schulischen Einrichtungen mit besonderem Fokus auf die Nährstoffversorgung
    (2014) Böhringer, Stefanie; Grimm, Peter
    Changes in society, such as growing number of employed women lead to a larger amount of schools in Baden-Württemberg that offer full time school programs. Due to this, the number of all day school pupils has more than tripled over the last 10 years (Landesinstitut für Schulentwicklung et al. 2011). As a result, in 2008, the Federal Ministry of Food, Agriculture and Consumer Protection set up the Vernetzungsstelle Schulverpflegung in Baden-Württemberg in joint financing with the Ministry of Rural Affairs and Consumer Protection. The Vernetzungsstelle Schulverpflegung Baden-Württemberg supports the schools in this new additional task of lunch catering and improves the quality and acceptance of the school meals in Baden-Württemberg. This study aims to evaluate and enhance the methods of the Vernetzungsstelle Schulverpflegung Baden-Württemberg to optimize the nutrition in educational institutions. For this purpose, ten schools with the corresponding seven canteens and 6000 pupils had been reviewed from June 2010 until October 2011 by the Vernetzungsstelle Schulverpflegung Baden-Württemberg. This supervision targets to improve the nutrition consumption of the pupils and thereby increase the amount of pupils with normal body-mass-index In order to reach this aim, both, the quality as well as the general requirements (e.g. menu, reservation) of the school lunch needs to be improved. Furthermore, the satisfaction of the customers as well as the resulting weekly participation in lunch at school canteens should be increased. Additionally, the pupils shall be sensitized for an appropriate diet. The “round table” is the fundament of the supervision of schools by the Vernetzungsstelle Schulverpflegung Baden-Württemberg. Several target groups come together to organize the improvement of the school canteen. For each school canteen, individual important optimizing and advertising strategies take place. Optimizing strategies include the training of caterers and canteen personal. Advertising strategies comprise several events, like pasta day or Santa Clause day, which help to raise the acceptance of the school canteen. To be able to measure the changes caused by intervention, an analyses takes place at the beginning and the end of the the study. For that, the surrounding conditions are evaluated by an expert interview with the responsible person of the school canteen. The satisfaction of the customers, such as pupils, teachers and parents is evaluated by written questionnaire. The quality of the lunch is analyzed by the criteria of the DGE quality standards of school feeding. Additionally, anthropometric data, like body height, body weight and abdominal girth, of six and seventh class pupils are measured. A bioelectric impedance analysis determines the body composition. Furthermore, a food frequency questionnaire and a 24h recall are conducted. Results of the study show, that during the time of intervention, on average 8 optimizing strategies and 15 advertising strategies are executed. 2991 (2966) pupils, 1939 (1785) parents and 143 (114) teachers take part at the first (second) survey. The cooperation of the schools with the Vernetzungsstelle Schulverpflegung Baden-Württemberg leads to an increased acceptance of the scool canteen by pupils, teachers and parents. Pupils and parents upgrade the school canteen judgment (scale 1-5) from 2,8 to 2,4 and teachers upgrade from 2,5 to 2,2. The cooperation doesn´t lead to an improvement of the nutrition composition of the canteen food. The pupils declare that they eat in the city more rarely, however rather bring food from home or eat at home. These changes in lunch habbits, though, do not have any impact on the total nutrition intake of the pupils from the sixth and seven grades (N first evaluation=436, N second evaluation=413). Therefore, neither the antropometroc parameters nor the body composition of the pupils are influenced. The methods of the Vernetzungsstelle Schulverpflegung Baden-Württemberg can be used successfully to raise the acceptance of the school canteen. Reasons, why there have been no changes in the nutrition intake of the pupils, can be discussed versatile. One explanation is that the intervention phase is too short in order to take measurable influence on the nutrition intake. As a result of the cooperation one can say that the school canteen initially needs to be integrated in every day school life, in order to improve the lunch catering. Moreover, the schools should make sure that one person takes responsibility for the catering. In addition to that, all involved parties have to work together on the optimization. Not until these points are settled, optimizing strategies, such as quality improvement of the canteen food, can´t be possible and successful. Finally, the food offer needs to be acceptable for the pupils, in order to be advertising in a good way.
