98 children with simple obesity were investigated. The prevalence of cardiovascular diseases (hypertension, coronary heart disease including heart infarction, disturbances of the cerebral circulation) and diabetes in parents and relatives of the obese children have been evaluated. The relation between the type of obesity (androidal, gynoidal) and the prevalence of the above complications in the family history was assessed. No correlation between the type of obesity and the mentioned diseases was observed.

Distribution of the fat tissue has been estimated in 94 children with simple obesity and in 100 children with normal parameters of the somatic development. The relation of waist measurement (at the navel level) to the hip measurement (at the level of sacral bone) (p/b) was evaluated. This ratio was higher in the group of the obese than in the normotensive children. Higher values of the waist measurement can indicate an excessive fat tissue deposition in the epigastrium. This is a poor prognostic factor as it indicates the greater risk of complications of obesity. This children should be followed up.

A trial of evaluating static and dynamic loads in man by means of analysis of the variability of instantaneous heart rate.

The instantaneous heart rate changes were examined in 12 forest workers during following tests: increasing (up to refusal) dynamic load on ergometer, rest in erect position, static load (about 75% of body weight) in erect position. The ECG signal, carrying information on heart rate, was amplified and processed by means of an especially designed heart rate analyzer. The dynamics of heart rate changes was evaluated through the analysis of differences of subsequent instantaneous heart rates and of distributions of heart rate accelerations and decelerations during the tests. Significantly different distributions of instantaneous heart rate changes as well as of accelerations and decelerations were observed for different loads.
