GORDURA ABDOMINAL VISCERAL AVALIADA POR IMAGEM EM HIPERTENSOS DE COMUNIDADES QUILOMBOLAS DE ALCÂNTARA-MA

Abstract

Introduction: Advances in the study of obesity and its correlation with the metabolic syndrome, association with systemic hypertension and diabetes mellitus corroborated the need for a more detailed assessment of body fat distribution, focusing on central obesity, which is characterized by adipose tissue storage compartments predominantly in subcutaneous and visceral abdominal and is inserted between the components of metabolic syndrome, visceral with emphasis on component which can be included among the risk factors for developing or worsening of cardiovascular diseases, and chronic renal disease. Importantly the above morbidities are correlated with ethnicity, highlighting the high prevalence of hypertension in young adults and refractory to anti-hypertensive drugs in the Afro-descendant population. Objective: To quantitatively identify the visceral abdominal fat in the resident population of African descent in Quilombola Communities in the Municipality of Alcântara (MA). Methods: The PREVRENAL research project aimed to estimate the prevalence of kidney disease in adults living in maroon communities in the municipality of Alcântara - MA, and visceral abdominal fat was quantified in hypertensive individuals, diabetics, hypertensive and diabetic selected to perform computed tomography of the abdomen, with protocol single predetermined volumetric section in the L3-L4 time and subsequent analysis in a workstation with appropriate software to measure the amount of adipose tissue, using a cutoff point set for both sexes. The examinations were filed in laptop used exclusively for this purpose, containing own program for radiological image view. Numerical data of the visceral fat volume were stored in specific computerized database created in EPI INFO 2000 to PREVRENAL project. Results: The results found a strong association between the measure of waist circumference and increased visceral fat, according to the literary described in several scientific research. Conclusion: The anthropometric indicators showed high correlation with the amount of visceral adipose tissue, especially waist circumference, higher among men. The prevalence of central obesity rates in the Maroons population, black ethnicity showed no significant difference in percentage values reported in the literature in the general population.
