Cardiovascular disease, which progresses by many risk factors with their interactions, has different causes at an individual level. The strategy required against it is also different among the subjects. An assessment of a patient's lifestyle in detail and strategy focused on the specific problems should, therefors, be performed. However, the methods to assess lifestyle in detail and to use the results for patient education have not yet fully been established for the health education programs carred out in Japan. A health education program against hypercholesterolemia, which is one of the cardiovascular risk factors, also has the same problem. A self-administered diet history questionnaire (DHQ) was used to assess dietary habits, especialy nutrient intake, at an individual level and the results applied for brief dietar ycounselling, in addition to conventional group-education during a 4 -month health education program performed in Hikone city, Shiga prefecture, Japan. A control group with only con-ventional group-education was established for comparison. After the program had been completed, statistically significant favorable changes in the intake level of saturated fatty acids, P/S rati, and Keys score were apparent for only the case group. The cholesterol intake level also declined, although no statistically significant difference was apparent between the groups. There was no significant change in any other nutrients in both groups. The results indicate that an individual dietary assessment and brief counselling based on DHQ might be effective for dietary modification with a community-based health education program in which group-education has normally been used.
