Healthy eating is essential for children's growth and prevention of chronic diseases such as obesity, heart disease, cancer and diabetes. However, for a number of reasons, healthy eating is not commonly practiced among local students. The Department of Health has recorded a rising trend of obesity among primary school students, from 16.4% in 1997/98 to 18.7% in 2004/05. That is to say, almost one in five school children is obese. In 2005, Chronic diseases accounted for almost 60% of all registered deaths. In the face of the rising trend of childhood obesity, the need to tackle this complex medical, educational and social problem is pressing. With the support of the Education Bureau, Committee on Home-School Co-operation, School Headmasters'/Headmistresses' Associations and other organisations, the 'EatSmart@school.hk' Campaign was launched in the 2006-2007 academic year. The movement aims to cultivate healthy eating practices so that children can grow healthily and learn effectively.
