Prevalência de obesidade visceral estimada por equação preditiva em mulheres jovens pernambucanas

Abstract

The accumulation of visceral fat is considered a major risk factor for cardiovascular and metabolic diseases. To determine the prevalence of visceral obesity and to assess its association with cardiovascular risk factors in young women from the state of Pernambuco. Cross-sectional study carried out with data from the "III Health and Nutrition State Survey", involving women aged 25 to 36 years. The following variables were evaluated: body mass index (BMI), Waist Circumference (WC), waist-to-height ratio (WHtR), volume of visceral fat (VVF) estimated by a predictive equation, Systolic and Diastolic Blood Pressure (SBP, DBP), total cholesterol (TC), Triglycerides (TG), fasting glucose (FG). A total of 517 women were evaluated, with a median age of 29 years (27-32) and prevalence of visceral obesity of 30.6%. BMI, SBP, DBP and TG were higher in the group with visceral obesity: BMI = 28.0 kg/m2 (25.0 to 21.4) vs. 23.9 kg/m2 (21.5 to 26.4) , SBP = 120.0 mmHg (110.0 to 130.0) vs. 112.0 mmHg (100.0 to 122.0), DBP = 74 mmHg (70-80) vs. 70 mmHg (63-80); TG = 156.0 mg / dL (115.0 to 203.2) vs. 131.0 mg / dL (104.0 to 161.0), respectively, p < 0.01. Age, SBP, DBP, TG and TC levels were significantly and positively correlated with the VVF: r = 0.171, 0.224, 0.163, 0.278, 0.124 respectively, p < 0.005. A high prevalence of visceral obesity was observed, being statistically correlated with cardiovascular risk factors.
