目的：サルコペニアを有する高齢2型糖尿病患者（T2DM）の栄養摂取量の特徴を明らかにする。

方法：栄養食事指導歴のある高齢T2DM 56名（73.6 ± 5.8歳）を対象にサルコペニアの特徴および栄養摂取量を調査した。

結果：サルコペニア（S）群では糖尿病罹病期間が長く（p = 0.009），3 年間平均HbA1cが高かった（p = 0.006）。S群では炭水化物%エネルギー（C%E）が高く（p = 0.027），脂質%エネルギー（F%E）が低かった（p = 0.026）。また，重回帰分析において男女とも最大握力に対しC%Eで負の関連を認めた。

結論：栄養食事指導を受けているサルコペニアを有する高齢T2DMではC%Eが高くF%Eが低い特徴を示し，C%Eの高さは特に最大握力と強い負の関係性を認めた。

Objective: We aimed to characterize nutritional intake in elderly type 2 diabetic patients with sarcopenia.

Method: We investigated the characteristics of skeletal muscle mass and strength and nutritional intake in 56 elderly people with type 2 diabetes who had received nutritional dietary guidance (age 73.6 ± 5.8 years).

Results: The prevalence of sarcopenia was 19.6 %. The sarcopenic group had a longer duration of diabetes (p = 0.009) and a higher mean HbA1c over the past 3 years (p = 0.006). The sarcopenic group had higher carbohydrate % energy (C%E) (p = 0.027) and lower fat % energy (F%E) (p = 0.026). Furthermore, multiple regression analysis showed a negative association between C%E and maximum grip strength in both men and women.

Conclusion：In elderly type 2 diabetic patients who received a standard nutritional care, sarcopenia was associated with high C%E and low F%E. High C%E was particularly strongly correlated with maximum grip strength.
