Abstract
ABSTRACTBackground: The study of body composition in patient candidates for bariatric surgery is directly related to the increase and distribution of body fat in the development of cardiovascular disease. Aim: To correlate anthropometric indicators and bioelectrical impedance in the assessment of body fat in female candidates for bariatric surgery. Methods: Cross-sectional, observational study of 88 women. The weight, height, body mass index and waist circumference data were evaluated in the anthropometric analysis. The body fat was determinate by bioelectrical impedance conducted according to the manufacturer´s recommended technique with a specific severe obesity formula. The patients were divided into two subgroups according to the average waist circumference and body mass index for better analysis of the results. Results:The group had a mean age of 39.7 years (±7.2), average weight of 125.6 kg (±16.2), mean body mass index of 48.7 kg/m2 (±6.4) and the mean waist circumference 137.6 cm (±12.4). Negative and significant relationship between BMI values waist circumference and resistance obtained by bioelectrical impedance were found. By analyzing the two groups the mean BMI and waist circumference, a significant relationship was observed, ie, the higher the degree of obesity less resistance was obtained by bioelectrical impedance. The higher is the obesity the lower is value found for resistance. Conclusion: The increase of anthropometric indicators (BMI and waist circumference) determined reduction in resistance and reactance obtained by bioelectrical impedance analysis in obese women candidates to bariatric surgery.
Highlights
Obesity has a multifactorial etiology including genetic predisposition, environmental and behavioral factors[19]
Body composition estimation is in constant concern in relation to the increase in body fat, and its distribution, in relationship to cardiovascular diseases[8,14]
The assessment of body composition can be performed with the use of anthropometric indicators, such as weight, height and waist circumference, and by technical devices as bioelectrical impedance[8]
Summary
Obesity has a multifactorial etiology including genetic predisposition, environmental and behavioral factors[19]. In studies on the quality of life of patients eligible for bariatric surgery, Costa et al reported that obesity interferes in physical, emotional, psychological and social aspects[5]. Body composition estimation is in constant concern in relation to the increase in body fat, and its distribution, in relationship to cardiovascular diseases[8,14]. The assessment of body composition can be performed with the use of anthropometric indicators, such as weight, height and waist circumference, and by technical devices as bioelectrical impedance[8]. Anthropometry is inexpensive method, easy to apply and equations exist in order to predict the body composition using height, weight and waist circumference[7]. Waist circumference has higher correlation with visceral adiposity when compared to MRI and CT11
