| Outline of Final Research Achievements |
The aim of the present study was to explore differences in beta cell mass according to the glucose tolerance status.Autopsy samples who underwent a 75-g oral glucose tolerance test were selected in the Hisayama Study.In the Japanese population,beta cell mass decreased with worsening glucose tolerance from the stage of prediabetes.

| Academic Significance and Societal Importance of the Research Achievements |
近年1型、2型糖尿病ではともに膵β細胞量が減少していることが報告され、β細胞の障害が糖尿病に共通した病態であることが強く示唆されている。しかしながら、日本人における糖代謝関連因子とβ細胞量との関係は十分に明らかでない。本検討での耐糖能の悪化に伴うβ細胞量の段階的な減少を示した結果は、2型糖尿病の発症前段階からβ細胞量を維持する治療戦略の重要性を示唆する。
