Loneliness in Adults Linked to Increased Risk of Diabetes, Study Finds

Recent research presented at ENDO 2025, the annual meeting of the Endocrine Society in San Francisco, highlights a concerning connection between social isolation and the risk of developing diabetes among older adults. The study reveals that adults aged 60 to 84 who experience social loneliness are at a significantly higher risk of having high blood sugar and poor glycemic control. Analyzing data from the National Health and Nutrition Examination Survey (NHANES) from 2003 to 2008, researchers evaluated the health profiles of approximately 38 million older Americans. They found that socially isolated seniors are 34% more likely to have diabetes and 75% more likely to struggle with managing their blood sugar levels effectively. Lead researcher Dr. Samiya Khan from the Keck School of Medicine emphasizes that social factors, especially loneliness, are critical social determinants of health that can influence the development and management of chronic conditions such as diabetes. The findings underscore the importance for healthcare providers to recognize social isolation as a potential risk factor in elderly patients, along with traditional medical and lifestyle factors. In the context of a rapidly aging population and growing social isolation worldwide, these insights are vital for improving preventive strategies and patient care. Addressing social connectivity could play a crucial role in mitigating the risk of diabetes and enhancing overall health outcomes for older adults.
