The following results were obtained: a) the prevalence of one risk factor was about 55%, and of two or more associated risk factors was of approximately 9% in the age group from 20 to 39. There was found to be a prevalence of about 51% and 57%, respectively of two or more associated risk factors for the age groups from 40 to 59 and 60 years of age and over; b) the prevalence of lipemic disorders proper was of about 49%, 58% and 57% respectively, for the age groups of 20 to 39, 40 to 59 and 60 years of age and over. In these cases the most prevalent risk factors among men were alcoholism and hypertension, either isolatedly or associated with obesity, and among women the most prevalent was obesity, alone or associated with hypertension; c) the most prevalent lipemic disorder was due to HDL-cholesterol, mainly among the younger people. The prevalence lower-than-normal HDL-cholesterol, was of about 28% and of "other lipemic disorders" was of 22% in the age group between 20 and 39 years of age.
