Abstract

The aim of this study was to verify general and central obesity, as well as the association of anthropometric indicators with cardiovascular risk factors (CvRF) in teachers of the private network of Viçosa-MG. A cross-sectional observational study was conducted with 150 teachers. Body mass index (BMI), conicity index (CI), body adiposity index (BAI), waist-to-hip ratio (WHR), waist-to-height ratio (WHtR), waist circumference (WC), abdominal circumference (AC) and body fat percentage (%BF); systolic blood pressure (SBP) and diastolic blood pressure (DBP); glycemia (GL), total cholesterol (TC), high density lipoprotein (HDL-C), low density lipoprotein (LDL-C) and triglycerides (TG) were evaluated. The prevalence of general and central obesity was calculated in addition to the simple linear regression to verify the association of anthropometric indicators between themselves and with CvRF. General and central obesity was identified in 19% and 17% of teachers respectively. The best associations between anthropometric indicators were between BMI and WHtR (R² = 0.81), WHtR and AC (R² = 0.78) and BMI and AC (R² = 0.76), all of which were positive. Between anthropometric indicators and CvRF, the best associations were found between WHtR and TG (R² = 0.25), AC and SBP (R² = 0.18) and WHR and HDL-c (R² = 0.19), the first two associations being positive and the last negative. It was concluded that approximately one in five teachers presented obesity. The general obesity indicator, BMI, was positively associated with anthropometric indicators and with most CvRF. However, central obesity indicators presented greater explanatory power on CvRF.

Highlights

Excess body weight is characterized by increased deposition of adipose tissue in the body, and obesity is a complex chronic disease of multifactorial origin, associated with numerous comorbidities, including type 2 diabetes, arterial hypertension and cardiovascular diseases (CVD)[1,2]
Its etiology is associated with high caloric intake, low levels of physical activity, genetic, socioeconomic, environmental and personal factors, all of which play a crucial role in the pathogenesis of obesity[3]
Regarding central obesity (CO), the values obtained in this study (17%) are slightly lower than those obtained in the population of teachers of public schools in the same municipality, in which 23% of teachers presented obesity[10]

Summary

Introduction

Excess body weight is characterized by increased deposition of adipose tissue in the body, and obesity is a complex chronic disease of multifactorial origin, associated with numerous comorbidities, including type 2 diabetes, arterial hypertension and cardiovascular diseases (CVD)[1,2]. Obesity has increased significantly in the last 25 years worldwide, especially in underdeveloped countries, which account for 62% of the world’s obese population[4]. In Brazil, more than half of the population is overweight, a rate higher than the world average, and obesity accounts for 17.9% of this percentage, reflecting a 52% increase from 2006 to 20165. In the United States, direct and indirect costs with obesity are estimated at US$ 275 billion a year, and the costs involved with each obese individual are 42% higher compared to normal-weight individuals. Companies pay US$ 6.4 billion due to work leave and US$ 30 billion due to reduced productivity attributed to obesity[3]
