[Atherosclerotic cardiovascular diseases, dyslipidemia, hypertension, obesity, and diabetes mellitus in a population of the metropolitan area of southeastern Brazil. I--Research methodology].

An epidemiological study was carried out into the risk factors for the following atherosclerotic cardiovascular diseases: lipemic disorders, obesity, hypertension, diabetes mellitus as related to some factors which characterize life-style (sedentary, drinking, smoking and eating habits). The population studied belongs to the metropolitan area of S. Paulo.

[Serum lipids levels and some risk factors of cardiovascular diseases in a population of the municipality of São Paulo, SP (Brazil)].

An attempt was made to characterize lipemic levels according to sex, age and presence or absence of cardiovascular disease risk factors, in a population of 3,792 people between the ages of 20 and 59, in terms of smoking habits, obesity, family history of diabetes and use of oral contraceptives. Those individuals who did not present any of the risk factors mentioned were classified as "exempt". After submitting the data to variance analysis it was found that: for men between 20 and 49 years of age there were high significant differences in the averages obtained for the seric levels of total lipids, triglycerides and total cholesterol between "exempt" and obese and "exempt" and obese with a family history of diabetes; for the 50 to 59 age group there were significant differences in the average of the values corresponding to the seric levels of total lipids between "exempt" and those individuals in whom obesity appeared associated with smoking habits or associated with a family history of diabetes.

[The evaluation of cellular immunity in the aged by skin tests].

Unlabelled: Cellular immunity of persons over 60 years of age was evaluated by intradermal testing with ubiquitous antigens, such as PPD, Trichophytin, Candidine and Varidase (SK, SD-40-10 U/ml) and by skin sensitization with DNCB. The group consisted of 290 individuals, 95 men and 195 women, without any signs of disease other than the usual geriatric disturbances, such as osteoporosis, ostearthritis and mild systolic hypertension. No medication was used that could interfere with the results of the tests.
