The purpose of this study was to develop prediction models of sarcopenia in 1,894 Japanese men and women aged 18-85 years. Reference values for sarcopenia (skeletal muscle index, SMI; appendicular muscle mass/height2, kg/m2) in each sex were defined as values two standard deviations (2SD) below the gender-specific means of this study reference data for young adults aged 18-40 years. Reference values for predisposition to sarcopenia (PSa) in each gender were also defined as values one standard deviations (1SD) below. The subjects aged 41 years or older were randomly separated into 2 groups, a model development group and a validation group. Appendicular muscle mass was measured by DXA. The reference values of sarcopenia were 6.87 kg/m2 and 5.46 kg/m2, and those of PSa were 7.77 kg/m2 and 6.12 kg/m2. The subjects with sarcopenia and PSa aged 41 years or older were 1.7% and 28.8% in men and 2.7% and 20.7% in women. The whole body bone mineral density of PSa was significantly lower than in normal subjects. The handgrip strength of PSa was significantly lower than in normal subjects. Stepwise regression analysis indicated that the body mass index (BMI), waist circumference and age were independently associated with SMI in men; and BMI, handgrip strength and waist circumference were independently associated with SMI in women. The SMI prediction equations were applied to the validation group, and strong correlations were also observed between the DXA-measured and predicted SMI in men and women. This study proposed the reference values of sarcopenia in Japanese men and women. The prediction models of SMI using anthropometric measurement are valid for alternative DXA-measured SMI in Japanese adults.

一般に体組成の加齢変化としては,体脂肪の増加とともに全身筋量の低下が認められる.すなわち,高齢者は「肥満」と「やせ」の問題を同時に抱えていることになる.現在の生活習慣病対策では,国民の医療費適正化対策の一環として,メタボリックシンドロームの基準値に基づいた特定保健指導が義務付けられているが,介護予防の観点から考えると,加齢による筋量およびそれに伴う筋機能の低下,すなわちサルコペニア対策も重要であると考えられる.本稿では,サルコペニアおよびメタボリックシンドロームと運動・身体活動,体力,遺伝との関連について解説し,生活習慣病予防のためのテーラーメイド運動処方プログラムの可能性について言及する.
