[Determination and assessment of biological age in 40-85-year-old persons]

Biological age was determined separately for men and for women in a series of 120 subjects (66 women) aged 40-85 years (mean age 66 +/- 11.6 years). The established biological age correlated significantly with the chronological age of the subjects investigated. For the calculation of functional age a battery of 10 tests covering 7 functional systems was developed to meet the requirements of the geriatrician and one of 6 tests covering 5 functional systems for the conditions of the general practitioner. The tests are undemanding as to time and procedure and reflect age and sex differences in the population of 40-85 year old people. A new method for the evaluation of biological age was suggested and used, namely the method of interval assessment and of correction of biological age with respect to the chronological age of the proband.
