[Knowledges of foodstuffs in relation to adult diseases in Japanese students--results from Japan Know Your Body Study].
As part of developing the Know Your Body (KYB) program for Japan, a questionnaire survey was administered assessing knowledge, attitudes, and behavior regarding cigarette smoking, alcohol drinking, dietary lifestyle and exercise. The subjects, about 13,000 in total, were students in elementary, junior and senior high schools in 9 prefectures. The main results concerning knowledge of foods that cause or prevent adult diseases are as follows: 1) Correct responses on the relationship of excessive salt intake and hypertension were made by 39% of males and 41% of female in the fifth grade of elementary school. In the third grade of junior high school, the percentage of correct answer for the same question increased to 80% of males and females, and in the third grade of senior high school, it rose to 90% of males and 91% of females. No clear sex difference was seen in all the grades of school. 2) Less than 23% of the students from the first to fourth grade of elementary school knew the word "cholesterol" and could distinguish high cholesterol foods. In the sixth grade of elementary school, more than 50% of students knew the word "cholesterol". In the third grade of junior high school, more than 50% of students could distinguish high cholesterol foods correctly and recognized the relationship of excessive cholesterol intake to heart disease. These results provide a basis for determination of the age for introducing nutrition education. 3) The percentage of correct answers for distinguishing green-yellow vegetables, showed a clear sex differential. The percentage of correct answers concerning dietary fiber was 75% for males and 81% for females in senior high school.
