Índice de massa corporal e circunferência abdominal: associação com fatores de risco cardiovascular

Abstract

Objective: To evaluate the association between cardiovascular risk factors and the anthropometric values -body mass index (BMI) and waist circumference (WC). Methods:It was studied 231 employees of Federal University of Viçosa, Brazil, 54,1% of them were men (21-76 years old) were measured. Glycemia, total cholesterol, LDL, HDL, triglycerides, blood pressure, BMI, WC, waist-to-hip ratio and body fatness. It was also investigated smoking, alcohol consumption and physical activity. Results:The prevalence of overweight/obesity in this population was high mainly in women. The abdominal obesity was observed in 74% of the women and 46,1% of the men. The average of BMI, body fatness, total cholesterol, HDL and triglycerides were significantly higher in men than in women. (p < 0,05). The sedentary lifestyle was a risk factor for obesity. Smoking and alcohol consumption were more common among men and normal weight volunteers. Most of the correlations between anthropometric indices and risk factors for cardiovascular diseases were significant, but weak and the WC was the index that had the strongest correlation and that associated with the largest number of variables. It was observed that with an increase of the BMI and the abdominal fat, there was also an increase of the glycemia, triglycerides and blood pressure and a decrease of HDL. The metabolic syndrome was more common among men and overweight and obese volunteers. Conclusion:In this study, the frequency of cardiovascular risk factors increased along with BMI and WC. Demographic transition, mainly characterized by a decrease in fecundity and reduction in infant and preschooler mortality, has resulted in an increasingly higher life expectancy in the Brazilian population 1

Prevalence of obesity, overweight and abdominal obesity and its association with physical activity in a federal University

“…The obesity and sedentariness represent a major public health problem, due to the accelerated increase in its prevalence and association with adverse effects on the cardiovascular and metabolic health at increasingly early ages [1][2][3] . High prevalence of obesity (BMI ≥ 30 kg/m²) and overweight (BMI ≥ 25 kg/m²) have been observed in the adult Brazilian population.…”

Prevalência e fatores associados à hipertensão em trabalhadores do transporte coletivo urbano no Brasil

“…Referido dado pode se relacionar diretamente com o consumo de gordura pela maior parte da população, assim como com o grande número de sedentários, considerados aqueles que não praticavam atividade física por tempo superior a trinta minutos e mais de três vezes por semana. Esses fatores são apontados por estudos pregressos que mostram a significância da obesidade quanto à gênese da hipertensão arterial, aumentando seu poder quando associada à alimentação inadequada e ao sedentarismo, expondo esses indiví-duos a alterações cardiovasculares e, conseqüente-mente, a maior risco de morbidade e mortalidade quando não tratadas essas alterações 13 .…”

Tractor operator anthropometric profile of the Brazilian Northeast State

“…Therefore, awareness campaigns should be carried out in the region due to the high number of heart disease and other diseases related to obesity. Operators with overweight, especially with abdominal fat, are more likely to cardiovascular risk diseases and consequently may have a higher death risk if diet changes are not taken (Rezende, 2006).…”
