Schools are regarded as an important setting for the prevention of overweight. This study presents a nationally representative picture of the obesogenity of the school environment, the awareness of schools regarding overweight, and actions taken by the schools aiming at overweight prevention. In addition, differences between school levels were studied.
In 2006-2007, questionnaires were sent to all Dutch secondary schools (age group 12-18 years). Prevalences of the outcome variables were calculated for the schools in total and by school level. The association between school level and outcome variables were analysed by a log linear regression.
Unhealthy foods and drinks are widely available at secondary schools. One third of the schools indicated that overweight has increased among students and half of the schools agreed that schools were (co)responsible for the prevention of overweight. Only 3% of the schools have a policy on overweight prevention. Small differences were observed between vocational education schools and higher education schools. The presence of vending machines did not differ by school level, but at vocational education schools, the content of the vending machines was less healthy.
This study describes the current situation at schools which is essential for the development and evaluation of future overweight prevention policies and interventions. In general, secondary schools are not actively involved in overweight prevention and the nutritional environment at most schools could be improved. The small differences between school levels do not give reason for a differential approach for a certain school level for overweight prevention.
学校被视为预防超重的重要场所。本研究呈现了学校环境致肥胖的全国代表性图景，学校对超重问题的认识，以及学校为预防超重而采取的措施。此外，还研究了不同学校层次之间的差异。
2006-2007 年，向所有荷兰中学（12-18 岁年龄组）发送了问卷。计算了学校总样本和不同学校层次的肥胖发生率。采用对数线性回归分析学校层次与肥胖相关变量之间的关系。
不健康的食品和饮料在中学广泛供应。三分之一的学校表示学生超重的情况有所增加，一半的学校认为学校（共同）有责任预防超重。只有 3%的学校有预防超重的政策。职业教育学校和高等教育学校之间存在细微差异。自动售货机的存在与学校层次无关，但在职业教育学校，自动售货机的食品更不健康。
本研究描述了学校的现状，这对于制定和评估未来的超重预防政策和干预措施至关重要。总的来说，中学并没有积极参与超重预防，大多数学校的营养环境还有待改善。学校层次之间的微小差异并没有为特定学校层次的超重预防提供差异化方法的理由。
