[Occupationally-induced diseases, a contribution to epidemiologic methodology with results from mining].

For mining exposures the work-relatedness of morbidity measures and functional organ-related disorders was analysed on the base of data concerning medical screening, occupational exposure and disablement. Morbidity corresponds with intensity of occupational exposure. Using risiko measures results for disorders were interpreted in relation to a hypothesis, which allows to distinguish in our opinion diseases without work-relatedness from work-related and occupational diseases. The availability of a "normal exposed" control group and the choice of a well-defined exposed group, for which the definition of selected diseases as work-related is applicable alone, are decisive for the results. For mining exposures functional disorders of muscular and skeletal system require particular consideration.

[Observations on the course of borderline hypertension in workers in ore mining with variable occupational body burden].

The blood pressure response of 198 ore miners--working above ground as well as underground--suffering from borderline-hypertension was checked over a period of 5 years. After a period of 5 years 40.9% of the test persons developed a hypertension in 18.7% of the miners the blood pressure returned to normal and with 40.4% it remained within the limits. No statistically significant relationship could be established between the blood pressure response and the various work loads such as the complex work load on face workers, work above ground and underground, shift work, the total time away from home, physically heavy work as well as exposure of the body or part of it to vibrations. Since the individual risk of developing hypertension, particularly with regard to people affected by borderline-hypertension, cannot be predicted the factory doctor has to provide for the adequate health care the group in question.

[The effect of occupational stress on blood pressure of miners in ore mines].

It was tried to analyse the influence of occupational load on the blood pressure reaction of miners. 200 miners at the age of 25-45 years with a large number of simultaneously affecting loadings at the place of work were examined with regard to the incidence of hypertension within a period of 5 years. The incidence of hypertension was 0.90%. To investigate the blood pressure reactions during an eight-hour shift we chose 2 technologies of mining differing concerning the loading factors, especially the intensity of physical load. In each case 5 miners of the technologies propulsion and mining were examined before the descent, during the eight-hour shift and after having finished the shift and the blood pressure was taken paying attention to standard conditions. The systolic blood pressure taken during an underground mining shift was significantly lower than the systolic blood pressure before the descent and after the shift, while a slight ascent of the diastolic blood pressure was insignificant. In spite of the different physical load we found no signs for a relevant displacement of the blood pressure level. A influence of working on the blood pressure reaction was found neither in the incidence of hypertension nor in the measurements of the blood pressure during an eight-hour miner's shift.

[Diagnostic specific values of disability duration--a contribution to the epidemiologic analysis of empirical morbidity figures].

In view of the great importance of the disablement period for the sickness figure, a method for interpreting empirical distributions of disablement periods is presented which yields practical information for optimizing diagnosis-specific disablement case periods. By approximating the disablement period distribution via a log-normal distribution, the location parameters mode, median and other quantiles can uniquely determined. The cumulatively determined frequencies of the disablement days with reference to chosen location parameters illustrate the possibilities of maintaining the capacity to work and the necessity of intensifying the medical care if diagnosisuntypical disablement periods are exceeded. To establish these requires further research of concrete long-dated disablement cases.

[Drug-taking behavior of workers with hypertension in the health service of the Wismut public health district].

In 353 workers with a medicamentously stabilized high blood pressure following an educational lecture on hypertension the compliance was determined by means of a patients' questionnaire. Circa 70% of the hypertensives reported to take regularly the medicaments prescribed, in which cases approximately 50% admitted to discontinue the taking of medicaments without having conferred with the attending physician when the well-being was disturbed. As essential factors influencing the compliance 4 features were determined: the opinion concerning the duration of the treatment of hypertension, the attitude to the prescription of medicaments, the frequency of taking the tablets and the observation of the terms of control of blood pressure, whereas, for instance, age, working place, professional activity and shift work had no remarkable influence. Before long an improvement of the compliance can be achieved by the decrease of the information deficit proved and by an improved motivation in form of the group therapy. A necessary prerequisite is the complete registration and comprehensive treatment in the dispensary of the works medical officer with established control terms, short times of waiting and sufficient time for a talk between physician and patient.

[Epidemiology of chronic bronchitis from the viewpoint of occupational medicine].

In a comprehensive epidemiological study the influence of age, smoking and exposure to dust upon the prevalence of chronic bronchitis could be confirmed and quantified. From the quantified contributing factors it is evident that chronic bronchitis after exposure to dust cannot generally be declared as occupational disease. The relative risk of heavy smokers of 1,9 is of the same order as the relative risk after 20 years' exposure to dust. Individual measures of health control and health care are necessary and should be intensified after 10 years of exposure.
