Epidemiology of risk factors of atherosclerosis and preventive program for youth.

In 2208 boys aged 15 to 22 years the incidence of risk factors of atherosclerosis were determined. The risk factors were found in 33.7% of boys. The level of risk factors in youth has increased with age (p = 0.001), especially hypertension (p = 0.001) and smoking (p = 0.001). The authors concluded that the most important methods of prevention of atherosclerosis in youth should be: identification of high-risk individuals (overweight, hypertension, hyperlipidemia, family history of CHD and PAD, ischemic postexercise ST segment depression), health education and motivation for change, modification nutritional habits in cases of hyperlipidemia and overweight (prevention of early atherosclerotic lesions in childhood), early diagnosis and control of hypertension, practice of low salt intake, avoidance of smoking, sufficient physical activity (prevention of atherosclerotic disease mainly in adulthood).

The authors suggest that identification of high-risk individuals, modification of nutritional habit, preventing the smoking habit, increased physical activity, low salt intake, and early diagnosis and treatment of hypertension should be the most important methods used for atherosclerosis and IHD prevention in youths.

A group of 201 boys of vocational schools living in an area of developing industry (Belchatów) and another area of developed industry (Lódz) were examined twice: at the age of 16-17 (I examination) and 14-18 months later (II examination). Incomplete right bundle-branch block and intraventricular conduction impairment have been demonstrated mainly in the resting ECG tracings (Table I). The risk factors of coronary heart disease were increasing with age, especially in boys of Belchatów area (Table II). Five boys with risk factors of coronary heart disease exhibited ischaemic type of postexertional ST segment changes (Table III).

The investigations were aimed at an evaluation of the health status of mining-and-power engineering school pupils from the viewpoint of classification to work at a strip mine and power station. Special attention was paid to the detection of possible causes of atherosclerosis and coronary heart disease 811 boys aged 14--20 were examined. Their physical development was good. No pathologies in the respiratory tract were found. Hands force was normal. Of six analysed risk factors most frequent were: hypertension and smoking habit. The percentage of pupils affected was increasing with age: arterial hypertension (from 5.5% to 15.7%) and smoking habit (from 6.1% to 43.3%).

Sport training and some activities of human polymorphonuclear leukocyte lysosomes.

The acid phosphatase and protease, neutral protease, bactericidal and mitogenic activities were determined in the polymorphonuclear leukocyte (PMNL) lysosomes of 16 years old boys. The investigated group consisted of 20 intense sport training persons during the last six years, the control one of the same age boys without any sport training. The significant decrease of hydrolase activity has been observed in the lysosomes of the peripheral blood PMNL's of the sport training boys.
