RESUMO
Under the influence of a primary prevention trial of coronary heart disease carried out for 10 years (1971-1982) in male subjects aged 40 to 60 years at entry, the curves of the seasonal variation of the incidence of myocardial infarction, sudden death and stroke were changed. The most important reductions of the incidence of these events were registered in spring and in September. In the rest of the year the effect of the action becomes variable according to the month and to the particular major events. These observations are discussed as related to their possible cause and to the necessity of a change of action methodology according to the period of investigation.

A group of 4800 men, aged fourty to sixty at entry, subjected to a multifactorial prevention trial of coronary heart disease for a ten-year period, showed spontaneous seasonal variations of serum cholesterol, characterized by increases in winter and decreases in summer. The authors discuss the relationship between the food changes and the seasonal variation of serum cholesterol values.

The paper presents the evolution of the levels of smoking, hypercholesterolemia, essential hypertension and obesity in the course of a prophylactic action carried out for 15 years (1971-1986) in a group of 5000 males aged 40-60 years. In the group still available after 15 years of follow up consisting of 2000 subjects, a decrease was obtained in the number of smokers, from 22.3% to 5.6% of hypercholesterolemia from 31.3% to 23.7%. The cumulated incidence of essential hypertension has increased from 15.5% to 36.7% and of obesity from 12.6% to 14.4%. At the same time the incidence of angina pectoris and myocardial infarction increased from 1.1% to 5.3%. For comparison are presented data obtained in a similar control group.

Arterial hypertension in adolescents was studied in a group of 899 school boys aged 15-18 years from the vocational school No. 48 of the Bucharest Transport Enterprise (ITB) and the secondary school No. 19 ITB. Essential arterial hypertension in the group investigated was found in proportion of 2.7%, a percentage comparable with that of other European countries (1-3%).
