[Human biological age].

By biological age is understood that state of the organism, with the inclusion of both physical and psychic parameters, which has been reached at a certain point of the chronological age. Experiments are reported which have been conducted in an attempt to measure the biological age of human beings by the aid of batteries of tests. So far, more than 1000 subjects have been examined, and they include both "normal subjects" and groups of patients showing such risk factors as overweight, hypertension, and diabetes mellitus. The motivation for such studies is the desire to satisfy practical needs. To tackle this problem it is necessary that investigators representing the various disciplines of gerontology should work closely together.

[Creativity and age in the arts and sciences (author's transl)].

Studies into the relations between aging and creativity are reported. After a brief review of statistics on works of medical scientists, the author deals with the age-dependent creativity of composers and, more specifically, symphonists. Using the method of differential analysis of works, he then analyzes and discusses the composing activities of Beethoven, Brahms, and Bruckner.

[Serum uric acid - the longitudinal behavior and age (author's transl)].

The longitudinal behavior of serum uric acid was studied by regular determinations made on a total of 195 subjects (of whom 53 were males and 142, females) between 1968 and 1978. The concentration of uric acid showed a significant increase within ten years irrespective of age, sex, and body weight. Nutritional influences, problems of physical and mental activity, therapeutical measures and agents, as well as hormonal alteration are discussed as possible cause thereof. There were no correlation between change in relative weight and uric acid level. Serum cholesterol and uric acid trends showed negative correlations in young men and positive correlations in older men.

[Socioeconomic importance of obesity].

It is reported on the annual deficiency of work, the stay in the hospital and the sanatorium as well as on the expenditure for these criteria which were established on 346 males with normal weight and 1,041 males with overweight and females at the age of 18--59 years within the research project nutrition and effect. With growing overweight in women as well as in men the days of deficiency of work, the duration of the stay in the hospital and the cost for this increase. In these cases the dependence on age concerns persons with normal weight and obese persons. It is referred to the prevention and early treatment of obesity.

[Frequency of bacteriuria in the aged (author's transl)].

1125 inhabitants of 2 homes for aged people were tested for bacteriuria by dip slides. Increasing of age did not lead to higher frequency of bacteriuria, neither in women (n = 869), nor in men (n = 256). The persons were divided in the 4 decades of being 61--70, 71--80, 81--90, and 91--99 years old. The corresponding rates of bacteriuria (greater than or equal to 10(5) germs/ml) were 14.0, 15.0, 12.4, and 9.1%, respectively. The rate of reproducibility was 75.4%, indicating still smaller values in reality. The discrepancies to the much higher values reported in the literature may depend on the people tested: "normal persons" instead of hospital patients or patients' specimens having been sent to a microbiological laboratory.

[Diagnostic standards in geriatrics (author's transl)].

This paper, which is based upon and interdisciplinary discussion of the subject by members of the Geriatrics Division of the G.D.R. Society of Gerontology, deals with questions concerning the elaboration of standards of diagnosis in geriatrics. In addition to general considerations, the author discusses a number of those problems which general practitioners and specialists in internal medicine usually come up against. Complete solutions cannot, in the present state of development, be offered. Rather, efforts are being made to invite experts, by the raising of questions, to further discuss the whole subject in order to arrive at definite rules of specific diagnosis by drawing on as wide a range of experience, findings, and information as possible.

[Epidermiologic studies on nutritional behavior of adipose subjects].

In 1,000 obese persons and 250 persons with normal weight detailed anamneses of nutrition concerning the average daily intake of calories, carbohydrates, protein, fats, cholesterol, saturated and manifold unsaturated fatty acids were made. Obese persons ingested less food than persons with normal weight, - findings which on the one hand are explained with the different habits of eating in the dynamic phase (the hyperalimentation takes place above all in this phase) and the stationary one of obesity, on the other hand a further differentiation in hypophages, normophages and hyperphages should be performed. Finally frequency and structure of the meals are of importance. Tendencies of age did not occur in females, whereas all nutrients in males, beginning with the fourth decade of life, were ingested in a smaller degree than in adolescence. Longitudinal studies on the behaviour concerning nutrition are desirable.

[Behavior of the body weight in 2261 maturity-onset diabetics under conditions of ambulatory care].

Of 2,261 maturity-onset-diabetics (970 males, 1,691 females) body weight, size and Broca-index were established at the beginning of the treatment, one year after the beginning of the treatment and at the date of analysis (x=5.7 years after the manifestation of diabetes). 72% of the females and 49% of the males had a Broca-index of more than 10 at the beginning of the treatment. The average loss of weight of the diabetics of adult type with overweight with a Broca-index of more than 5 was in the first year 7.6 kg in males and 5.2 kg in females. In the first year after beginning of the disease in the diet group and in the buformin group was achieved an average reduction of weight in males of about 7 kg and in females of about 6 kg. After the first year of treatment in the groups mentioned the body weight remained or rose to one kg. The patients treated with sulfonylureas--compared with the diet-biguanide group--showed in the first year of treatment, indeed, a loss of weight which was about 50% smaller, however, also in the following years (x=4.7) a further continuous reduction of weight could be recognized. The initial results and the late results in the treatment of elderly diabetics with overweight show that, compared with former years, partial success is to be achieved with reduction cures performed in outpatient departments. The importance of the reduction of weight in elderly diabetics for the improvement of the carbohydrate tolerance and the fat metabolism is emphasized.

[On the relations between overweight and age (author's transl)].

There are reported new results on pathogenesis, etiology, and classification of adiposity under consideration of the age. The examinations show, that the postulated hyperphagia of the adipose person cannot be demonstrated so simply, therefore it is necessary to make longitudinal studies in further researches in this field. There are given simple directive rules for classification of the adipose persons to overcome the common uncertainly in this regard. New studies on the motivation of adipose persons for visiting a adiposity dispensary show an age dependence, in which in younger persons mostly esthetic causes, in the elderly sanitary causes are important.

[Primary hyperlipoproteinemia and cardiovascular diseases in relation to age].

The primary hyperlipoproteinaemia is a frequently appearing disease of the second half of life. Out of 188 patients with hyperliporpoteinaemia 19% were at an age of 40-49 years, 33% at an age of 50-59 years and 51% of 60-69 years. The type IV of hyperlipoproteinaemia was the most frequent one (19%), in the second place was type IIa (21%) and in the third place was type IIb (14%). In the 5th decade of life type IV prevailed in males and type IIa in females, in the 6th and 7th decade of life nearly the same percentage for these types was to be found in both sexes. In 60% of the patients with hyperlipoproteinaemia we found a hypertension, in males in 20% coronary insufficiency appeared already in the 4th decade of life, then it rose to 70%, in females these appearances occurred about 10 years later. 9% of the patients fell ill from myocardial infarction. A general arteriosclerosis appeared in 63% of the males and in 89% of the females beginning with the 5th decade of life, then it still increased. Therefore, adequate preventive and curative measures (diet and pharmaca) are necessary in time.

[Methodological problems in the determination of biological age].

It is reported on a new method of the establishment of the biological age. The test battery designed comprises 12 parameters, from which a so-called biological index can be calculated which on its part serves as basis for the establishment of biological age. The realisability of the methods is demonstrated by examinations carried out on 340 healthy persons. The method developed for the geriatric practice is regarded as supplementation of the general medical examination and for the clarification of certain, above all gerontologically orientated questions.
