ObjectiveTo estimate the prevalence of a set of risk factors for non-transmissible chronic diseases and compare it to that found 15-16 years ago in a similar survey. Methods A cross-sectional household survey was carried out comprising a random sample of people aged 15-59 years in the city of São Paulo between 2001 and 2002. The total of 2,103 people answered a questionnaire and had their blood pressure, weight, height, waist and hip circumferences measured. For a third of these participants, their total cholesterol, HDL-cholesterol, triglycerides and glucose levels were determined. ResultsThe total age-adjusted prevalences in the study age group were as follows: smoking, 22.6%; uncontrolled blood pressure, 24.3%; obesity, 13.7%; increased waist circumference, 19.7%; total cholesterol ≥240 mg/dL, 8.1%; HDL-cholesterol <40 mg/ dL, 27.1%; triglycerides ≥200 mg/dL, 14.4%; and blood glucose ≥110 mg/dL, 6.8%. Smoking, uncontrolled blood pressure, high total cholesterol, low HDL-cholesterol and high triglycerides were significantly more prevalent in men than women. ConclusionsThe prevalences of a set of risk factors for chronic diseases showed men to have a poorer condition than women. In comparison to the previous survey, the prevalence of uncontrolled blood pressure remained unchanged but the prevalence of smoking has significantly lowered. methodology, most of them were conducted separately and at different points in time (Volta Redonda, 7 1979-1980 Fortaleza, 19 1985; Araraquara, 10 1987; Piracicaba, 1 1988; Cotia, 15 1990 Cotia, 15 -1991 Ilha do Governador, 8 1991-1992 Pelotas, 6,17 1992 and Passo Fundo, 21 1995; Catanduva, 4 1998), making it difficult to identify geographical differences and temporal changes. Few exceptions are the studies on diabetes in Brazilian capitals 13 and on obesity trends in urban and rural areas. 16 Porto Alegre is perhaps the only Brazilian city where the prevalence of hypertension was measured at two points in time, in the 70's and in the 90's. were later excluded because they were found to be pregnant or puerperal women.The final sample was then composed of 2,103 people who answered a questionnaire applied by trained nurse interviewers, and had their blood pressure, weight, height, waist and hip circumferences measured twice. Most (70.9%) interviews were performed on weekends (42.7% on Saturdays and 28.2% on Sundays), and 29.1% were equally distributed on the other five weekdays. A 10% randomly selected subsample of interviews had their integrity checked by telephone, and showed no discrepancies.About a third of participants (759), randomly selected, answered a quantitative nutrition questionnaire and 700 had a fasting venous blood sample collected at home; as 59 (7.8%) refused to have their blood drawn. In order to minimize the interference of overeating on weekends, blood collection was not carried out on Sundays and was avoided on Mondays. Blood samples were processed for determinations of plasma glucose and serum total cholesterol, HDL-cholesterol and trig...
OBJECTIVE: To determine the following parameters in the Brazilian State of São Paulo: 1) the percentage of deaths due to acute myocardial infarction (AMI) occurring in hospitals; 2) the percentage of deaths due to AMI occurring in public health system hospitals as compared with all in-hospital deaths due to AMI between 1979 and 1996; 3) the fatality due to AMI in public health system hospitals from 1984 to 1998. METHODS: Data were available on the Datasus Web site (the health information agency of the Brazilian Department of Health) that provided the following: a) number of deaths resulting from AMI in hospitals; b) number of deaths resulting from AMI in public health system hospitals; c) number of hospital admissions due to AMI in public health system hospitals. RESULTS: The percentage of in-hospital deaths due to AMI increased from 54.9 in 1979 to 68.6 in 1996. The percentage contribution of the public health system to total number of deaths due to AMI occurring in hospitals decreased from 22.9 in 1984 to 13.7 in 1996; fatality due to AMI occurring in public health system hospitals had an irregular evolution from 1984 to 1992 and showed a slight trend for increased frequency from 1993 to 1998. CONCLUSION: The percentage of in-hospital deaths due to AMI has been increasing. Deaths resulting from AMI in public health system hospitals have decreased when compared with the total number of deaths due to AMI in all hospitals. Fatality due to AMI in public health system hospitals did not decrease from 1992 to 1998.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
