We aimed to compare the level of agreement between leg-to-leg bioelectrical impedance analysis (LBIA) and dual-energy X-ray absorptiometry (DXA) for assessing changes in body composition following exercise intervention among individuals with Type 2 diabetes mellitus (T2DM). Forty-four adults with T2DM, age53.2±9.1years; BMI30.8±5.9 kg/m2participated in a 6-month exercise program with pre and post intervention assessments of body composition. Fat free mass (FFM), % body fat (%FM) and fat mass (FM) were measured by LBIA (TBF-300A) and DXA. LBIA assessments of changes in %FM and FM post intervention showed good relative agreements with DXA variables (P<0.001). However, Bland-Altman plot(s) indicated that there were systematic errors in the assessment of the changes in body composition using LBIA compared to DXA such that, the greater the changes in participant body composition, the greater the disparity in body composition data obtained via LBIA versus DXA data (FFM,P=0.013; %FM,P<0.001; FM,P<0.001). In conclusion, assessment of pre and post intervention body composition implies that LBIA is a good tool for assessment qualitative change in body composition (gain or loss) among people with T2DM but is not sufficiently sensitive to track quantitative changes in an individual’s body composition.

Aims.To determine the progression of body weight (BW) and body composition (BC) in patients with type 2 diabetes mellitus (T2D) on insulin therapy and the consequences on muscle strength (MS) as a reflect of free fat mass increases.Research design and methods.We analysed BC using air displacement plethysmography and MS by hand grip dynamometry in 40 T2D before and after three (M3) and six months (M6) of insulin therapy.Results.at baseline HbA1c was 9.76±1.6% and BW was stable with fat mass (FM) 28±10.7 kg; and fat free mass (FFM) 52.4±11 kg; at M6, HbA1c improved to 7.56±0.8%; insulin doses tended to increase. BW gain at M6 was+3.2±4.2 kg and with an increase of only 25% by M3; it was composed of FM, whereas FFM was unchanged. MS did not increase on insulin therapy.Conclusions.In T2D, BW gain was composed exclusively of FM with no improvement in MS.

Background:Obesity is an important health problem, as its prevalence has reached an epidemic level and continues to increase steadily resulting in higher risk of cardiovascular diseases and metabolic disorders. Currently, new methods and criteria are being developed to assess fat and muscle mass, as well as criteria for diagnosing obesity and sarcopenia.Aim:To assess the quantitative composition of muscle and adipose tissue in type 2 diabetes mellitus patients based on the dual-energy X-ray absorptiometry for the diagnosis of obesity and sarcopenia.Materials and methods: We examined 42 type 2 diabetic in-patients admitted to the Department of Therapeutic Endocrinology. Dual-energy X-ray absorptiometry was performed in all patients with subsequent assessment of the composition of muscle and fat tissue.Results:If assessed by the body mass index, all patients had an excess body weight: median, 32.25 [29.75; 35.70]; in men, 31.3 [28.19; 34.63], in women, 32.29 [30.26; 36.54]. 26.2% of the patients (11/42) were overweight, but not obese. Female patients had more severe obesity than male (in total, 33.3% (10/30) of women had 2ndand 3rd degree of obesity, while men 16.7% (2/12)). The assessment by the fat mass index (FMI) showed that 2.4% (1/42) of the patients were normal-weight. Median FMI was 11.91 [10.40; 13.78] (in men, 8.86 [7.46; 12.1], in women, 12.35 [11.55; 15.47]). Overweight was found in 52.4% (22/42) of the patients; in total, 2ndand 3rddegree of obesity was observed in 25% (3/12) of the men and only in 6.6% (2/30) of the women. Median Appendicular Lean Mass Index (ALMI) in the total group was 7.99 [7.32; 9.05], being expectedly higher than in women: 9.19 [8.42; 9.45] and 7.58 [7.24; 8.49], respectively. Median T-score ALMI was 2.32 [1.73; 3.08], Z-score ALMI 2.15 [1.47; 3.54]. In general, there was a decrease in the appendicular muscle mass with age. There was an inverse correlation between the age and T-score ALMI (r = -0.319, р = 0.020), as well as between the age and Z-score ALMI (r = -0.634, p = 0.000). According to the results of T-score ALMI and Z-score ALMI, there were no patients with sarcopenia. However, the calculation of the T- and Z-criteria, corrected for fat mass, has led to a significant decrease of the medians of these parameters and allowed to identify a group of patients meeting the criteria of sarcopenia (97.6%, 41/42).Conclusion:Based on ALMI, T-ALMI, and Z-ALMI, there were no patients with sarcopenia. After these criteria were corrected for fat mass, the number of such patients increased to 97.6% (41/42) and 85.7% (36/42), respectively. The potential use of the adjusted T-ALMI (FMI) and Z-ALMI (FMI) as criteria for sarcopenia and muscle mass reduction compared to the age-related normal values, as well as the classification of obesity by FMI should be studied in large epidemiological studies in different populations.
