Malnutrition assessed by controlling nutritional status is correlated to carotid atherosclerosis in patients with type 2 diabetes

摘要

Diabetes and malnutrition sometimes overlap. Little is known about the relationship between malnutrition and subclinical atherosclerosis in patients with type 2 diabetes. This cross-sectional study investigated this relationship in patients with type 2 diabetes. We evaluated the relationships between malnutrition assessed by controlling nutritional status (CONUT) score and subclinical atherosclerosis assessed by carotid intima-media thickness (IMT) and carotid plaque scores in 461 consecutive patients with type 2 diabetes. Nutritional assessment indicated that 38% of patients were malnourished (CONUT ≥3). Carotid IMT and carotid plaque scores were significantly higher in patients with malnutrition. Multivariate linear regression analyses revealed that a high CONUT score (CONUT ≥3) was correlated with mean IMT (β = 0.196, p = 0.043) and max IMT (β = 0.243, p = 0.011) in patients taking statins and was also correlated with mean IMT (β = 0.287, p = 0.004), max IMT (β = 0.308, p = 0.002), and plaque score (β = 0.190, p = 0.044) in patients not taking statins after adjusting for age, sex, duration of diabetes, body mass index, hemoglobin A1c, creatine, smoking, and hypertension. Our results demonstrate a relationship between malnutrition and subclinical atherosclerosis in patients with type 2 diabetes.
