Limitations of the Study 1279 The data are from self-reports and hence responses might be subject to social desirability considerations, although there was no reason for parents and teachers to distort their opinions as they were provided with an envelope to return their completed questionnaires; in addition, the teachers responses were anonymous. The schools included in the intervention study were recruited by e-mail. While the Internet offers a cheap- and quick way to contact many schools simultaneously, a disadvantage is, however, the low response rate (10% school response in the intervention study). A more personalized communication and follow-up by telephone usually leads to a higher response rate; however, this was considered not feasible because of limited time, staff, and budget resources. Caution is necessary in generalizing the results, especially those concerning the satisfaction with their own school‟s food policy, bearing in mind that response from schools was low, that parents‟ opinions are based only on those of 16 schools, that only a small number of fathers participated in the study, that there might be a bias in selection of the parents and teachers participating in the study, and that the data of parents and teachers were collected in the context of two different studies for which different schools were approached. 6. Conclusions Parents agree that schools should create a context for their children where healthy food choices and behaviours are promoted: while nutrition should be part of the curriculum, snacks and soft drinks should be restricted; however, to replace fruit juice and sugared milk drinks with sugarless alternatives would take special effort. Teachers are in general even more supportive to restrict less healthy food items. Parents would appreciate availability of fruit at school and like to be informed about what happens at school, including the dietary behaviour of their child. Parents of lower educational background are more likely to be more permissive (= would restrict less food items at school).
