| Outline of Final Research Achievements |
This study examined the association between dietary patterns of local residents focusing on the quality and quantity of fat and their history of cardiovascular-related diseases and cancer. Four dietary patterns of "healthy", "high-fat/meat", "low-fat/fish", and "fruit/dairy" dietary patterns were extracted from the data of the food frequency survey of 7,438 people. The groups with higher scores for "low-fat-fish" and "fruit-dairy" had lower histories of hypertension, diabetes, and cancer. In addition, men with a history of cancer had a significantly higher percentage of saturated fatty acids (palmitic acid) in their blood than men without. These results suggest that, focusing on the quality and quantity of fat, dietary patterns low in fat and high in fatty acids in fish are associated with a history of hypertension, diabetes, and cancer.

| Academic Significance and Societal Importance of the Research Achievements |
近年、栄養疫学研究では、特定の食品や特定の栄養素の摂取ではなく食事パターンを用いた研究が増えている。しかし、脂肪の質や量に着目した食事パターンを抽出し、循環器関連疾患・癌との関連を総合的に検討した研究は少ない。本研究は、「低脂肪・魚型」食事パターンは、高血圧、糖尿病、癌の既往歴の頻度は低いことを示した。今後の研究の進展により、循環器関連疾患・癌と食事パターンの関連性を明らかにし、これらの疾患の発症を予防することが期待される。
