Body Composition with Dual-Energy X-Ray Absorptiometry and Bioelectrical Impedance Analysis in Breast Cancer Survivors.

ABSTRACT:

Background

Because obesity is an independent risk factor for breast cancer recurrence, assessment of body composition is crucial to guide weight management in breast cancer survivors (BCS). This study assessed whether dual-energy x-ray absorptiometry (DXA) and bioelectrical impedance analysis (BIA) yield similar results for body composition in BCS.

Methods

Body fat percentage, lean body mass, and fat mass were estimated using DXA and BIA under fasting conditions in 89 BCS. BMI categories included normal (18-24.99 kg/m² ; n = 28), overweight (25.0-29.9 kg/m² ; n = 21), obese (>30 kg/m² ; n = 23), and severely obese BCS (>35 kg/m² ; n = 17). Agreement between the devices was assessed by Bland-Altman analysis.
