Inclusion criteria

Inclusion criteria: Elderly subjects in a nursing care home for the elderly volunteered to participate in a 3-mo dietary supplement intervention program. All residents in this nursing care home need special care by other people for living. They are classified into Japanese nursing care levels with number between 1 and 5 based on assessed care needs.

Exclusion criteria

Exclusion criteria: Exclusion criteria are subjects with treated with parenteral nutrition, or difficulty of swallowing, or type 1 diabetes mellitus, severe heart failure, liver, kidney, blood disease, or FBS > 200 mg/dl, or blood creatinine >1.5 mg/dl or CRP >2.0 mg/dl or BMI > 23 to avoid a further increase in body weight, or food allergy to supplements used in this study.

Design outcomes

Primary

MeasureTime frame
Muscle function (locomotive and respiratory) and cognitive function at baseline and after 3-mo intervention are compared. Mid-upper-arm muscle area (AMA) is estimated by measuring triceps skin fold thickness (TSF) and mid-upper-arm circumference (AC); strength in the upper extremities is measured by a handgrip dynamometry; strength in the lower extremities is estimated by the leg extension power; muscle function is estimated by gait speed and iteration numbers in legs open and close; strength of respiratory muscles is estimated by peak expiratory flow (PEF) ;cognitive function is estimated by Mini-Mental State Examination (MMSE) and NM scale.

Secondary

MeasureTime frame
Under fasting conditions, blood concentrations in total protein, albumin, creatinine, total cholesterol, HDL-cholesterol, LDL-cholesterol, Triacylglycerol, free fatty acid, choline esterase, blood sugar, HbA1c, white blood cell number, red blood cell number, hemoglobin concentration, hematocrit, platelet number, iron concentration, C-reactive protein, acetoacetic acid, 3-hydroxybutyric acid, and total ketone bodies at baseline and after 3-mo intervention are compared.
