| Outline of Final Research Achievements |
This study aimed to analyze the relevance to B vitamins (vitamin B6, B12, folic acid), bone quality and bone strength factors. The subjects were elderly women. Subjects divided into two groups: intervention group that intake of food high in B vitamins and control group. Two groups were followed up at 9 months. Bone strength was evaluated by osteo sono-assessment index (OSI).In baseline, OSI was not associated with serum bone metabolic marker, homocysteine, vitamin B6, B12 and folic acid. However, dietary intake of vitamin B6, B12 and folic acid were showed a positive correlation with OSI.At nine months later, the control group was significantly decreased in OSI, but the intervention group did not change. OSI was associated with dietary intake of vitamin B6 and vitamin B12.
In this study, it was suggested that intake of the B vitamins was helpful to maintain the bone strength in the elderly women.

| Academic Significance and Societal Importance of the Research Achievements |
ビタミンＢ群高摂取の介入群は、コントロール群を比較して骨強度が減少せず維持していた。ビタミンB群摂取が、高齢女性の骨強度の維持に役立つことが示唆されたことは、高齢看護学における、食生活指導による在宅での骨粗鬆症性骨折予防への応用が期待できる。
