A few weeks ago the Yomiuri News on-line reported the following:

健診結果でこの数値が低いと、認知症リスクが…

　健康診断の血液検査項目の赤血球数やＨＤＬ（善玉）コレステロール値、アルブミン値が低いと、認知機能の低下が２～３倍起きやすいとの研究結果を、東京都健康長寿医療センター研究所のグループがまとめた。

　栄養が低い状態が将来の認知症のリスクを高めることを示す結果で、老年医学専門誌に近く発表する。

　同研究所の谷口優研究員らは、群馬県と新潟県に住む７０歳以上の１１４９人の暮らしぶりや健康状態を調べて、認知症が疑われた人などを除いた８７３人を追跡調査（平均２・７年）した。

　調査開始時の赤血球数、善玉コレステロール値、アルブミン値を、それぞれ「低い」「普通」「高い」の３群に分け、その後の認知機能の変化との関係を調べた。

　その結果、それぞれの値が低い群は高い群に比べて２～３倍、認知機能が低下しやすかった。

A research group came from the Tokyo healthy long-life medical center research institute summarized its research findings which showed that in the blood test of a medical examination, if the red blood cell count, the HDL (good) cholesterol count, and the albumin level were low, a decline in cognitive function might occur easier by 2-3 times.

The research result which showed that low nutrition situation could increase the risk of dementia in future was announced in a gerontology technical magazine recently.

Masaru Taniguchi and researchers of the research institute investigated for the first time the health condition and lifestyle of 1149 people who were aged over 70 living in Gumma Prefecture and Niigata Prefecture, and conducted a follow-up survey (on average 2.7 years) on 873 people except for those who was suspected to have dementia etc.

At the time when the investigation was started, their red blood cell count, the good cholesterol value, and the albumin value were divided into three groups of "low", "common", and "high" respectively, and then their relation with changes in cognitive function was investigated.

Based on the results, the group that had low values when compared with the high value group, showed a easier decline in the cognitive function by 2-3 times.

It is interesting to note that low nutrient level could increase the chance of dementia.
