Nutritional status of centenarians assessed by activity and anthropometric, hematological and biochemical characteristics

For the maintenance of good health of very old people such as centenarians, nutrition is very important. However, the information on their nutritional status is very limited. In this study, we evaluated the nutritional status of centenarians by comparison with elderly in their 70s and ;young adults....

Description
Summary:For the maintenance of good health of very old people such as centenarians, nutrition is very important. However, the information on their nutritional status is very limited. In this study, we evaluated the nutritional status of centenarians by comparison with elderly in their 70s and ;young adults. Volunteer subjects were comprised of 71 centenarians (51 females, 20 males) who were not bed ridden, 84 elderly in their 70s (51 females, 33 males) who had no specific health problems and 27 healthy young adults in their 20s (17 females, 10 males). We compared 11 'items 'of the activities of daily living (ADL), height, weight, hemato-logical (hemoglobin, hematocrit and red blood cell count) and biochem-ical [total protein, albumin, total-, HDL-, LDL- and VLDL-cholesterols, triglycerides, glutamate oxaloacetate transaminase (GOT), glutamate pyruvate transaminase (GPT) and creatinine] variables among the three age groups. Since the atrophy of muscle is more severe than the atrophies of other tissues in the elderly, we studied the muscle protein breakdown using plasma 3-methylhistidine (3-MH) as a marker. The results of all indices except serum lipids, GOT and GPT, were lower in the centenari-ans than in the subjects in their 20s (p
