摘要
Abstract Objectives We aimed to prospectively examine the association between regional body fat and risk of cardiovascular disease (CVD) in individuals with type 2 diabetes (T2D), who often exhibit changes in relative fat distribution and have increased CVD risk. Methods The main analysis included 21,472 participants with T2D from the UK Biobank. Regional body fat was measured by bioelectric impedance assessment. Cox proportional hazards regression models were used to estimate hazard ratios (HRs) and 95% confidence intervals (CIs). Results Over a median of 7.7 years of follow-up, 3,976 CVD events occurred. After multivariable adjustment, upper and lower body fat were independently and oppositely associated with CVD risk among patients with T2D. Higher arm fat percentage was linearly associated with increased CVD risk (P nonlinear >0.05), while higher trunk fat percentage was nonlinearly associated with increased CVD risk (P nonlinear <0.05). In contrast, higher leg fat percentage was nonlinearly associated with lower CVD risk (P nonlinear <0.05). When comparing extreme quartiles, the multivariable-adjusted HR (95% CI) of CVD was 0.72 (0.58, 0.90) for leg fat percentage, 1.63 (1.29, 2.05) for arm fat percentage, and 1.27 (1.06, 1.52) for trunk fat percentage. Similar patterns of associations were observed for all-cause and CVD mortality. In addition, leg fat percentage, but not other regional fat percentage, was associated with CVD risk independently of traditional measures of obesity. Conclusions Among people with T2D, arm fat and trunk fat were positively, whereas leg fat was inversely, associated with the risk of CVD and mortality. These findings highlight the importance of considering both the amount and the location of body fat when assessing CVD and mortality risk among individuals with T2D.
