Abstract:
Objective Constructing physiological-psycho-social three dimensional aging index system, and scale to provide a basis for evaluating the effects of human aging and anti-aging measures. Methods Evaluation, modification and determination of the second and third level indexed by Delphi and principal component analysis and other methods. The weight of each index was weighted by the analytic hierarchy process, and the reliability and validity were calculated on the basis of the preliminary scale. A large sample of empirical studied to determine the aging of different age groups standardized score distribution table. The best model for judging functional age was sought, based on a variety of biostatistical models. Results The aging scale was constructed by three levels, the first level included 3 indicators, the second level had 10 indicators, the third level included 51 indicators, and adopted by expert certification the national society. 3 184 valid questionnaires were obtained through epidemiological investigation, the average total score of aging was (46.93±11.07) points, and the scores of aging were positively correlated with age(r=0.785, P<0.001). The average scores of aging in each dimension were different and the difference was statistically significant (all P<0.001), and each dimension had significant difference with age. The growth model (R2=0.635) was selected, the curve of the relationship between the score of aging and age was fitted. Conclusions The three-dimensional human aging scale was scientific, feasible, and has good reliability and validity. The empirical results show that the comprehensive score of aging increase with age, and show certain characteristics and laws on the curve.
