This study aimed to evaluate the effect of adiposity and fat distribution on the odds of elevated cardiovascular risk factors among adults with type 2 diabetes mellitus.
The present cross-sectional study included 2,427 adults with type 2 diabetes mellitus. Body fat was assessed by dual-energy x-ray absorptiometry. Multivariate-adjusted logistic regression was used to estimate effects of adiposity parameters on elevated hemoglobin A (HbA , ≥7.0%), hypertension (blood pressure ≥140/90 mmHg), and elevated low-density lipoprotein (LDL) cholesterol (≥2.6 mmol/L).
The multivariable-adjusted odds ratio (OR) for elevated HbA was 0.82 (95% CI: 0.70-0.96) for each SD increase in leg fat mass. The multivariable-adjusted OR for hypertension was 1.15 (95% CI: 1.00-1.32) for each SD increase in android fat mass. Multivariable-adjusted ORs for elevated LDL cholesterol ranged from 1.16 (95% CI: 1.00-1.35) to 1.27 (95% CI: 1.06-1.51) for each SD increase in arm and android fat mass and percentage of total, truncal, arm, and android fat. Each SD increase in BMI, truncal-to-leg fat ratio, and android-to-gynoid fat ratio was significantly associated with increased risks of elevated HbA , hypertension, and elevated LDL cholesterol.
Subcutaneous fat in the lower body was associated with a more favorable glycemic profile, but not blood pressure or lipid profile, whereas central adiposity was associated with poor control of cardiovascular risk factors among patients with type 2 diabetes mellitus.
本研究旨在评估肥胖和脂肪分布对 2 型糖尿病成人心血管危险因素升高几率的影响。
本横断面研究纳入了 2427 例 2 型糖尿病成人。通过双能 X 射线吸收法评估体脂肪。采用多变量调整的 logistic 回归估计肥胖参数对血红蛋白 A(HbA,≥7.0%)、高血压(血压≥140/90mmHg)和升高的低密度脂蛋白(LDL)胆固醇(≥2.6mmol/L)的影响。
多变量调整后,腿部脂肪质量每增加 1 个标准差,HbA 升高的比值比(OR)为 0.82(95%可信区间:0.70-0.96)。安卓型脂肪质量每增加 1 个标准差,高血压的多变量调整 OR 为 1.15(95%可信区间:1.00-1.32)。多变量调整后,手臂和安卓型脂肪质量以及总、躯干、手臂和安卓型脂肪百分比每增加 1 个标准差,升高的 LDL 胆固醇的 OR 范围为 1.16(95%可信区间:1.00-1.35)至 1.27(95%可信区间:1.06-1.51)。体重指数、躯干-腿部脂肪比和安卓-女性型脂肪比每增加 1 个标准差,与 HbA、高血压和升高的 LDL 胆固醇升高的风险显著相关。
下半身的皮下脂肪与更有利的血糖谱相关,但与血压或血脂谱无关,而中心性肥胖与 2 型糖尿病患者心血管危险因素控制不良相关。
