Brief summary
The goal of this observational study is to compare glycemic control and irisin levels in subjects with diabetes mellitus type 2 with sarcopenic obesity vs non-sarcopenic obesity. The main questions it aims to answer are: Is glycemic control worse in diabetic patients with sarcopenic obesity? Are irisin levels higher in patients with non-sarcopenic obesity? Participants will be asked to: * Fill in three questionaries on lifestyle * Perform two physical performance tests The investigators will collect the following data: * Anthropometric measurements * Body composition by bioelectrical impedance analysis. * Results of routine blood analyses * Irisin levels by drawing a vial of blood from the antecubital vein
Detailed description
Patients will be enrolled from our Diabetology Center. Eligible patients will be contacted by phone to be informed of the procedures and to schedule the visit. The patients will come to the visit bringing the blood analyses they usually bring for the routine diabetologic visit; they will also be fasting for at least 3 hours, and abstaining from smoking and physical activity since the day before. All visits will be performed in the afternoon, at about 4-6 p.m. Participants will be asked to: * Fill in three questionaries (SARC-F \[Strength, assistance with walking, rising from a chair, climbing stairs, and falls questionnaire\], IPAQ-EIT \[International Physical Activity Questionnaire validated in the Elderly Italian population\], MEDI-LITE \[Adherence to the Mediterranean diet questionnaire\]) * Perform two physical performance tests (5-times chair stand test and handgrip test). Anthropometric measurements will be assessed; body composition will be evaluated by bioelectrical impedance analysis. A venous blood draw will be executed for evaluation of irisin levels after signing a written consent form.
