The relationship between multimorbidity and self-rated health is well established. This study examined self-rated health in relation to multimorbidity, glycaemia and body weight specifically in adults with type 2 diabetes. Bootstrapped hierarchical logistic regression and structural equation modelling (SEM) were used to analyse survey data from 280 adults with type 2 diabetes. The odds of ‘fair/bad/very bad’ self-rated health increased 10-fold in patients with three (OR = 10.11 (3.36–30.40)) and four conditions (OR = 10.58 (2.9–38.25)), irrespective of glycaemic control (p < 0.001). The relationship between multimorbidity and perceived health was more pronounced in male patients. SEM generated a model with good fit, χ² (CMIN) = 5.10, df = 3, p = 0.164, χ² (CMIN)/df = 1.70, RMSEA = 0.05, CFI = 0.97, TLI = 0.95 and NFI = 0.94; self-rated health mediated relations between multimorbidity and BMI. Overall, this study highlights the potential of self-rated health to mediate relationships between multimorbidity and BMI, but not glycaemic control, in adults with type 2 diabetes.

多种疾病和自评健康之间的关系已得到充分证实。这项研究特别调查了成人 2 型糖尿病患者的自评健康状况与多种疾病、血糖和体重的关系。使用引导层次逻辑回归和结构方程模型 (SEM) 分析 280 名成人 2 型糖尿病患者的调查数据。无论血糖水平如何，患有三种疾病（OR = 10.11 (3.36–30.40)）和四种疾病（OR = 10.58 (2.9–38.25)）的患者自评健康状况的几率增加了 10 倍控制（p  <0.001）。男性患者的多重发病率与健康感知之间的关系更为明显。SEM 生成拟合良好的模型，χ ² (CMIN) = 5.10，df = 3，p  = 0.164，χ ² (CMIN)/df = 1.70，RMSEA = 0.05，CFI = 0.97，TLI = 0.95 和 NFI = 0.94；自评健康介导多种疾病和体重指数之间的关系。总体而言，这项研究强调了自评健康在调节 2 型糖尿病成人患者多重发病率和 BMI 之间关系的潜力，但不能调节血糖控制。
