Assessing the body composition is important in adult patients with type 2 diabetes mellitus to prevent and achieve optimum control during treatment. Bioelectrical impedance analysis (BIA), being a more affordable method of assessing the body composition, should therefore be compared with the gold standard dual-energy X-ray absorptiometry (DXA) to look for a correlation between the two and the potential of BIA to be used widely in this population. A cross-sectional observational study was conducted on 60 patients attending the endocrinology outpatient department (OPD) of a tertiary care centre in Kolkata, India.
Body composition was measured by both BIA and DXA. Intra-class correlation (ICC) values were calculated between the two methods for fat mass and fat-free mass for three body mass index (BMI) groups and overall.
DXA and BIA correlated well for both fat mass and fat-free mass in the entire study population and in the non-overweight non-obese group (BMI <23) and the obese group (BMI ≥25). However, the overweight group (23 ≥BMI <25) did not correlate well with the above-mentioned parameters.
We suggest interchangeable use of the two methods in the non-overweight non-obese (BM I <23) and obese (BMI ≥25) BMI groups of adult subjects with type 2 diabetes mellitus. However, the low correlation for all parameters in the overweight group points towards exercising caution when taking such measurements by BIA and planning a further study with a larger cohort of such individuals to better evaluate the said correlation.
评估成年2型糖尿病患者的身体成分对于预防疾病以及在治疗期间实现最佳控制非常重要。生物电阻抗分析（BIA）作为一种更经济实惠的身体成分评估方法，因此应与金标准双能X线吸收法（DXA）进行比较，以寻找两者之间的相关性以及BIA在该人群中广泛应用的潜力。对印度加尔各答一家三级护理中心内分泌门诊的60名患者进行了一项横断面观察研究。
通过BIA和DXA测量身体成分。计算了三种体重指数（BMI）组以及总体的脂肪量和去脂体重在两种方法之间的组内相关系数（ICC）值。
在整个研究人群、非超重非肥胖组（BMI<23）和肥胖组（BMI≥25）中，DXA和BIA在脂肪量和去脂体重方面均具有良好的相关性。然而，超重组（23≤BMI<25）与上述参数的相关性不佳。
我们建议在成年2型糖尿病患者的非超重非肥胖（BMI<23）和肥胖（BMI≥25）BMI组中可互换使用这两种方法。然而，超重组所有参数的低相关性表明，在通过BIA进行此类测量时应谨慎，并计划对更多此类个体进行进一步研究，以更好地评估上述相关性。
