Smoking, consumption of alcohol and sedentary life style in population grouping and their relationships with lipemic disorders.

The study, part of the project "Atherosclerotic cardiovascular diseases, lipemic disorders, hypertension, obesity and diabetes mellitus in a population of the metropolitan area of the southeastern region of Brazil", had the following objectives: a) the characterization and distribution among typical human socio-economic groupings, of the prevalence of some particular habits which constitute aspects of life-style-the use of tobacco, the use of alcohol and sedentary activity; b) the establishment of the interrelation between the above-mentioned habits and some lipemic disorders. The prevalence of the habits cited behaved in the following manner: the use of tobacco predominated among men, distributed uniformly throughout the social strata; among the women the average percentage of smokers was 18.9%, a significant difference occurring among the highest socio-economic class, where the average was of 40.2%. The sedentary style of life presented high prevalence, among both men and women with exception of the women of the highest socio-economic level and of the skilled working class. The use of alcohol, as one would expect, is a habit basically practised by the men, without any statistically significant differences between classes.(ABSTRACT TRUNCATED AT 250 WORDS)

[Atherogenic food habits of population groups in a metropolitan area of southeastern Brazil]. / Hábitos alimentares aterogênicos de grupos populacionais em área metropolitana da região sudeste do Brasil.

This present study is one part of the project "Atherosclerotic cardiovascular diseases, lipemic disorders, hypertension, obesity and diabetes mellitus in a population of the metropolitan area of S. Paulo, Brazil" undertaken in Cotia county. An alimentary inquiry based on the alimentary history of the individual was carried out among a subsample of the population (568 individuals). The objectives of the inquiry are the following: a) the identification of the atherogenic potential of the diets of different human groups, stratified according to social class and b) the analysis of consumption differentials of some nutrients, which confer atherogenicity to the diet, as between social classes. The consumption differentials were analyzed as between men and women, by social class and taking the 50th percentile (P50) of the sample as the standard of reference, with regard to the following dietary constituents: energy, total proteins, proteins of animal origin, percentages of protein calories (P%), fatty acids, fats (F%) and carbohydrates (CH%). Also, according to this criterion, some diet profiles were analyzed in the light of the recommendations of the National Cholesterol Education Program (NEP) as regards the calorie supplied by fats (F%), saturated fatty acids (SFA%), carbohydrates (CH%) and cholesterol (> 300 mg/day). The following were the findings obtained: the consumption differentials were more pronounced among the men. The social class which presented the largest percentages above the P50 of the sample, with regard to energy, total proteins, fats and carbohydrates, were the non-specialized workers, i.e. the manual laborers who have a high expenditure of energy, an that of small property owners and shop-keepers who lead a sedentary life. The class of the greatest acquisitive power and highest educational level presented a moderate consumption of these constituents. On the other hand, the consumption of the proteins of animal origin, above the P50, among men and women, maintained a direct relationship with socioeconomic level. The proportion of calories coming from fats (F%) and protein (P%) was directly proportional to the acquisitive power of the class, while that of carbohydrates (CH%) presented an inverse relationship. On the other hand, the consumption of cholesterol in excess of 300 mg/day was found to between 37 and 50% and 20 and 32% for men and women, respectively. The percentage of diets with more than 30% of calories coming from fats (F%) varied from 25 to 40% for men and 45 to 50% for women. The participation of the saturated fatty acids (SFA%) in proportions greater or equal to 10 was relatively low for both sexes: being of 5 to 17% for the men and of less than 10% for the women. The percentages of cases in the relationship saturated to unsaturated fatty acids (SFA/UFA) maintaining values less than 1% was also low for the population in general, being of 7 and 22% for the men and less than 10% for the women. It is concluded that diet probably is an important risk factor in cardiovascular diseases, lipemic disorders, obesity and hypertension, for a large part of the population, mainly for the small property owners and shop-keepers, is viable.

[Atherosclerotic cardiovascular disease, lipemic disorders, hypertension, obesity and diabetes mellitus in the population of a metropolitan area of southeastern Brazil. II--Lipemic disorders]. / Doenças cardiovasculares ateroscleróticas, dislipidemias, hipertensão, obesidade e diabetes melito em população da área metropolitana da região Sudeste Do Brasil: II--dislipidemias.

This study has sought to characterize the prevalence of lipemic disorders and other risk factors of atheroschlerotic cardiovascular disease in population groups of Cotia county in Greater S. Paulo, Brazil. The population groups were defined on the basis of socio-economic characteristics and geographical location within the county such as provided elements for the delimitation of the "study areas". A sample representative of each of these areas was taken, constituting in all 1,041 individuals. The data related to eating habits were collected from a sub-sample of 568 people. The lipemic disorders diagnosed were as follows: high risk hypercholesterolemias with values approximately 240 mg/dl for total cholesterol and approximately 160 mg/dl for LDL-cholesterol; borderline risk hypercholesterolemias with values > 200 mg/dl and > 130 mg/dl for total cholesterol and LDL-cholesterol respectively; hypertriglyceridemia, with values approximately 250 mg/dl. The following risk factors were included: atherogenic eating habits (consumption of proteins of animal origin, saturated fats and cholesterol), smoking, drinking, sedentary life style, obesity (IMC > 25 kg/m2), hypertension (140/90 mmHg) and diabetes mellitus (glycemia > 120 mg/dl). The results found were the following: 1--the average number of risk factors was significant by greater among men than among women, for the age groups below 50 years of age (p < 0.01): between 50 and 55 years of age they were equal for the two groups, reaching their greatest value at 60 years of age with a sharp reduction after this latter age as regard the men but presenting a constant gradual increase for the women; 2--the average number of risk factors increased with age for both sexes (p < 0.01); 3--the prevalences of high risk hypercholesterolemias together with hypertriglyceridemia (> = 250 mg/dl) were significantly greater in the classes of higher socio-economic level; 4--the lipemic profile associated with lipemic disorders show that these latter rarely occur with just one constituent in isolation; 5--when the high-risk hypercolesterolemias are added to the borderline cases accompanied by two or more risk factors and hypertriglyceridemia they give a total of 39.2% of men and 32.8% of women, that is to say, 35.4% of the sample need immediate clinical-educational intervention.
