High prevalence of comorbidities in older adult patients with type 2 diabetes: a cross-sectional survey

Abstract Background Diabetes is a global health problem, and its incidence and complications increase with the duration of the disease and over time. This increase in complications in older patients can lead to disability and a lower quality of life. This study aimed to investigate the rate of diabetes control and complications in older adults. Method This was a cross-section of an ongoing cohort of patients with type 2 diabetes mellitus (T2DM) aged 65 years and older. The clinical and laboratory characteristics of older adult patients with T2DM in good and intermediate health conditions were collected between 2010 and 2022. Results A total of 2,770 older adult patients with T2DM were enrolled, including 1,530(55.3%) female and 1,240 (44.7%) male participants. Metabolic syndrome, hypertension, and coronary artery disease were the most common comorbidities, affecting 1,889 (71.4%), 1,495 (54.4%), and 786 (29.2%) patients, respectively. Albuminuria was present in 626 (22.6%) patients, while retinopathy was detected in 408 (14.7%) patients, including 6% with proliferative retinopathy. Most patients were treated with oral antidiabetic agents (88.9%), with metformin being the most prescribed medication (85.6%). Statins were prescribed to 71.8% of the patients. The most prescribed antihypertensive medications were angiotensin receptor blockers and angiotensin-converting enzyme inhibitors, prescribed to 54% and 15% of patients, respectively.
