Abstract

Abstract Anthropometry is considered a widely applicable and effective method to track adiposity. Among the current methods of anthropometric analysis are the Body Mass Index (BMI) and the Waist Hip Index (ICQ) are utilized. However, both presents limitations because they fail to estimate the adiposity. In this sense, recently the Body Adiposity Index (IAC) emerged as an important tool in the adipose mass evaluation of large populations. Thus, the present study aimed to evaluate adults aged between 18 and 50 years through BMI, IAC and ICQ and to analyze the agreement degree between the methods. A total of 2602 individuals were analyzed, of which 1457 were women and 1145 men. After analyzing the data, it was verified that the majority of the population are within the standards of men was classified as not overweight only for ICQ and women for BMI and ICQ. In contrast the population of men is classified as healthy only for ICQ and women for BMI and ICQ. Concerning the agreement between the methods, only a positive and significant agreement between BMI and IAC was observed. Therefore, it can be concluded that IAC is an alternative for assessing body composition, showing a good method to estimate the percentage of total body fat of men and women, thus increasing the possibilities of diagnosis of obesity and overweight.

Highlights

Obesity is a global public health issue[1]
An interesting study was conducted in 2005 with 27,000 participants from 52 countries highlighting the high number of people at risk for myocardial infarction through the ICQ assessment, and this risk was underestimated through the Body Mass Index (BMI) assessment
Corroborating with the present research, in Salvador (BA), a study of 634 individuals of both sexes with 316 adults aged between 20 and 59 years and 318 elderly aged over 60 years, showed a low-intensity agreement between BMI and the ICQ14.Current evidences indicate that ICQ is effective at predicting the risk of cardiovascular events, but BMI is more efficient at characterizing obesity than ICQ15

Summary

Introduction

The current obesity epidemic is related to the urbanization process, sedentary lifestyle, high-calorie diet, and alcohol and tobacco consumption[1,2]. Anthropometry is considered to be the most useful, inexpensive and non-invasive method for tracking obesity, and is universally applicable in large populations[3]. Among the main methods of anthropometric analysis are the Body Mass Index (BMI), Waist Hip Index (ICQ ) and Body Adiposity Index (IAC). The BMI is a low cost, fast, easy to apply and feasible method for treating large populations. BMI has limitations in determining body adiposity in athletes, individuals with a high percentage of lean body mass, children, the elderly and people of different ethnicities[4].On the other hand, ICQ is another widely used method because it has low cost and easy application[5]. The ICQ does not allow estimating the percentage of body adiposity
