Our purpose is to determine the prevalence of undiagnosed diabetes by checking HbA1c in patients hospitalized outside internal medicine services and assess whether or not there is a difference between those without diabetes awareness and those with known diabetes in terms of age, sex, education status, presence of comorbidity and Body Mass Index (BMI).

The study included 630 patients hospitalized outside internal medicine services and internal medicine side-branch services at or over the age of 18 whose anthropometric measurements could be made. The sociodemographic properties and comorbidities of the patients were recorded. Their anthropometric measurements, fasting blood glucose and HbA1c measurements were made. Those with a previous diagnosis of diabetes were grouped as 'Known Diabetes', those without a known diabetes diagnosis but with an HbA1c value of ≥6.5% during hospitalization were grouped as 'Diabetes Unaware', and those with an HbA1C value of <6.5% were grouped as 'No Diabetes'. Whether or not there were differences among the 3 groups based on sociodemographic characteristics, anthropometric measurements and disease statuses was examined.

Inclusion Criteria:

• Inpatients of units other than internal medicine services and internal medicine side-branch services at or
• Over the age of 18
• Anthropometric measurements could be made were included

Exclusion Criteria:

• Had comorbidities that could affect their anthropometric measurements (heart failure, edema, liver cirrhosis, cancer, cachexia, Cushing syndrome, etc.),
• Who had been using steroids for more than a month,
• Pregnant
• Postoperative period

The study was conducted at two different tertiary healthcare institutions located in Istanbul in Turkey. Patientswho were inpatients of units other than internal medicine services and internal medicine side-branch services at or over the age of 18 whose anthropometric measurements could be made were included. . The internal units included neurology, dermatology, physiotherapy and rehabilitation, cardiology, infectious diseases and pulmonology services, while the surgical units included general surgery, cardiovascular surgery, pulmonary surgery, orthopedics and traumatology, brain surgery, ophthalmology, urology, gynecology and plastic surgery services.
