Abstract:

Objective To explore the status of cardiopulmonary fitness in type 2 diabetes mellitus (T2DM) patients with fatty liver disease and its influencing factors. Methods One hundred and fourteen T2DM patients with fatty liver disease were selected and underwent cardiopulmonary exercise test (CPET). They were divided into the lower group and the higher group according to the median of VO2 peak. The difference of general data and clinical data were compared between the 2 groups. Multivariate Logistic regression analysis was used to analyze the influencing factors of cardiopulmonary fitness in T2DM patients with fatty liver disease. Results The median of VO2 peak was 20.95 (18.38, 23.72) mL·kg-1·min-1 in all 114 patients, accounting for 69% (62%, 81%) of the expected value. Compared with the higher group, patients in the lower group were older, the proportion of men was lower, the height was lower, the waist circumference was higher, the waist hip ratio was higher, the grip strength/weight was lower, the proportion of patients with smoking history was higher, the sedentary time was longer and the average daily activity was lower (P<0.05). Alanine aminotransferase (ALT), gamma glutamyl transferase (GGT) and triacylglycerol (TG) were increased in the lower group (P<0.05). Multivariate Logistic regression analysis showed that gender, grip/weight, smoking history and average daily activity were the independent influencing factors of VO2 peak in T2DM patients with fatty liver disease. Conclusion VO2 peak of T2DM patients with fatty liver disease is significantly reduced. Being female and having smoking increase the risk of reduced VO2 peak. Increasing the grip strength/weight ratio and increased daily activity can reduce the risk of the decrease in VO2 peak.
