Preventing childhood obesity – what we can learn from Japan

Abstract

The prevalence of being overweight or obese among children is increasing rapidly worldwide, placing a heavy burden on healthcare systems. However, Japan has one of the lowest rates of childhood obesity worldwide. Lifestyle factors such as physical activity and eating habits play a crucial role in the development of overweight and obesity. Physical activity forms the basis of Japan's public health strategy. Daily routines are designed to encourage physical activity. A notable example of this is walking or cycling to school. Additionally, schools play a central role in promoting physical activity through compulsory sports programmes. Another cornerstone of Japan's strategy to combat overweight and obesity is the 'Shokuiku' nutrition education programme. The Shokuiku School Lunch Law stipulates that school meals must meet strict nutritional standards and be prepared using fresh, locally sourced ingredients. Integrating nutrition education into everyday life means that what is learnt in the classroom leads to lasting behavioural changes. Japan's active commutes to school and nutrition education programmes instil healthy habits from an early age.
