Ⅳ. 연구 결과
주성분분석을 통한 장수 나이(longevity age)의 추정식은 73.729-1.178×성별 - 3.685 × 고혈압 유무 + 3.001 × 고지혈증 유무 -4.244×U1+1.518×U2-2.279×U3+3.044×U4(성별: 남성=0, 여성=1; 고혈압유무: 없음=0, 있음=1; 고지혈증유무: 없음=0, 있음=1; U1~4: 제 1~4주성분)으로 산출되었다. 질환의 유, 무에 따른 장수 나이를 분석한 결과, 건강노인의 실제 나이(72.4±1.2세)는 장수 나이(72.3±1.1세)와 차이가 나타나지 않았으나, 노인질환자의 장수 나이(74.0±0.8세)는 실제 나이(72.2±0.8세)보다 약 1,8세 높게 나타났다. 또한 규칙적인 운동습관이 있는 노인의 실제 나이(72.4±0.8세)는 장수 나이(72.7±0.8세)와 같은 경향을 나타냈으나, 운동습관이 없는 노인의 장수 나이(74.8±1.1세)는 실제 나이(71.9±1.4세)에 비해 약 2.9세 높게 나타났다. 본 연구에서 개발한 건강지표의 변화가능성을 검토하기위해 12주간의 걷기운동 프로그램을 실시한 결과, 노인의 실제 나이((68.3±5.6세)는 운동 실시 전 장수 나이((76.4±6.5세)가 약 8.1세 높게 나타났으나 운동 실시 후 장수 나이(70.1±4.5세)는 6.3세 젊게 나타난 것으로부터 본 연구에서 산출된 장수 나이의 타당성이 검증되었다.

Advances in medical care have enabled many middle-aged and older adults to live for long periods of time. The government has been interested in maintaining healthy aging. The longevity age, which is kind of biological age, has been suggested as an index of health of aging status. The longevity age is based on the assessment of an interaction among many specific characteristics within an individual. It is documented that the longevity age is useful for evaluating functional status for healthy people as well as for chronic disease patients such as atherosclerosis, stroke, hypertension, diabetes, and so on. First, the purpose of this study was to investigate the longevity age for the assessment of health and functional status in older adults based on 31 physical and physiological variables. Second, to determine principle factors responsible for the maintenance of health status or aging and the validity of equation for calculating the longevity age. Third, to assess the correlation analysis between the longevity age, and metabolic syndrome and physical activity.
One hundred ninety Korean men and women (aged 60-85 yrs) were recruited for this study. All subjects were free of any signs or symptoms of overt coronary heart disease, based on a health history questionnaire and were considered in good health. Body composition, blood pressure, blood lipid profiles were measured and physical fitness tests for the living were performed.
The fat-free mass was decreased as age increased, while the percent body fat was increased. The total cholesterol was significantly highest among the subjects aged between 60 and 65 years, while there were no differences in LDLC, HDLC, TG, and blood glucose concentrations between groups. The physical fitness, the functional tests, and the cardiorespiratory fitness were significantly decreased with aging. Taken together, the variables for assessing the physical fitness and cardiorespiratiory fitness could be used to determine to evaluate the physical fitness for the living in older population. The blood lipid profiles is useful to evaluate the metabolic syndrome and the VO2max could be used to evaluate the respiratory fitness for the living. Eleven principle factors were used to compute the longevity age in the subjects. Equation for calculation the longevity age is 73.729-1.178×sex-3.685×hypertension status+3.001×hypercholesterolemia status-4.244×U1+1.518×U2-2.279×U3+3.044×U4(R2=0.776). The chronic disease and physical activity status showed excellent correlation with the longevity age in our study.
In conclusion, this study may suggest that the equation derived for computing the longevity age applies to the assessment of the effectiveness in regular exercise older population as well as chronic disease patients. In addition, this equation will be a good index to improve and maintain the physical fitness for the living in older adults.
