Aim: To investigate the associations of high body fat and low muscle mass with arterial stiffness in Asian Indians with type 2 diabetes mellitus (T2DM) in North India. Methods: In this cross sectional study, subjects with T2DM (males n = 110, females n = 58, mean age: 53.8 ± 10.0 years) were recruited. Anthropometry and body composition analysis were performed and measures of glycemia, lipids and PWV were analyzed. Results: Significant positive correlation was observed between PWV and body fat (p < 0.05), left leg fat (p < 0.05), and right leg fat (p < 0.01) percentages only in females. In males, significant negative correlation was observed between PWV and truncal fat free mass (p < 0.05) and fat free mass in right arm (p = 0.05) and left arm (p < 0.05). In both males and females, significant negative correlation was observed between PWV and fat free mass in left leg (p < 0.01) and for right leg fat free mass only in females. Conclusion: Excess adiposity and low fat free mass are associated with arterial stiffening in Asian Indians with T2DM in North India, with significant gender differences. [ABSTRACT FROM AUTHOR]

Aim: To assess the prevalence of diabetic retinopathy (DR) and associated risk factors in Asian Indians with prediabetes.Methods: In a cross-sectional study conducted at two tertiary care diabetes centres in Chennai, India, clinical and biochemical assessment and nonmydriatic ultra-wide field fundus photography was performed in individuals with prediabetes (impaired fasting glucose [IFG] and/or impaired glucose tolerance [IGT]) based on oral glucose tolerance test (OGTT) and/or glycated hemoglobin (HbA1c) between 5.7% and 6.4% in 2019. The retinal photographs were graded by certified ophthalmologists. Systemic risk factors associated with DR in prediabetes were assessed.Results: The mean age of the 192 individuals with prediabetes was 48 ± 13 years (55.2% were males). DR was present in 12 (6.3%) individuals of which nine (4.7%) had mild non-proliferative DR (NPDR) and three (1.6%) had moderate NPDR. None had severe sight-threatening DR. The Poisson multiple regression analysis showed that after adjusting for other systemic covariates, HbA1c values ≥ 6% (6-6.4%) was associated with 2 times higher relative risk of DR (Risk ratio 1.95 (95% CI 1.07-3.545, p = 0.028) in comparison to HbA1c < 6%).Conclusion: DR was present in about 6% of the Asian Indians with prediabetes. Higher HbA1c values among individuals with prediabetes was associated with twice the relative risk for DR. Robust control of HbA1c should be encouraged even before the diagnosis of diabetes is established. [ABSTRACT FROM AUTHOR]
