Abstract
The prevailing life style in Japan has been westernized and highly industrialised. This inevitably has bad effects on nutrition and the eating pattern of youth. These ill effects may be summarized as follows, 1) lack of daily physical activities, 2) an increasing number of working mothers, 3) irregular timing of food intake, 4) an increasing intake of energy in the form of fat, 5) increasing consumption of processed foods ready for eating, 6) lack of integrated management systems such as health education programs against atherogenic risk factors. These changes have resulted in increasing atherogenic risk factors among young people. It is necessary to study the present risk factors and their relation to prevailing life styles and to organize a follow-up system for surveillance of risk factors.
