Lausanne [Switzerland]: Type 2 diabetes (T2D), a chronic condition affecting hundreds of millions of people worldwide, is commonly caused by the body's inability to make enough insulin or use it correctly.
To avoid negative outcomes and long-term complications such as limb amputation or heart problems, patients must understand how to manage the condition on a daily basis.
A team of researchers in Portugal has now assessed how many patients - both insulin-treated and not insulin-treated - have this crucial knowledge about T2D. They published their findings in Frontiers in Public Health.
Scientists found that many people with type 2 diabetes know little about their condition, indicating a need to improve communication about the disease.
"Our main motivation was to contribute to the reduction of the existing disparity in the knowledge that diabetic patients have regarding their disease," said first author Prof Pedro Lopes Ferreira, director of the Center for Health Studies and Research of the University of Coimbra. "With this study we evidenced the need to improve the disease knowledge of type 2 diabetic patients."
Knowledge levels vary widely
To measure diabetes knowledge, the researchers employed a test designed for persons with type 1 or type 2 diabetes. The test, among other things, asks about diet, signs and symptoms, and medication control. The research included 1,200 diabetics, over 40 per cent of whom were treated with insulin. The remainder of the sample followed particular diets, with some also using non-insulin oral antidiabetics, while others depended only on food.
The results showed that many participants (71.3 per cent) could answer food-related questions correctly, and that more than four out of five respondents demonstrated good knowledge of the positive impact of physical activity. More than 75 pre cent of respondents also knew about the best method for testing blood sugar levels.
In other areas, however, the researchers found that knowledge was severely lacking. For example, when asked which food item should not be used to treat low blood sugar levels, only 12.8 per cent of participants answered correctly. The lowest percentage (4.4 per cent) of correct answers was on a question concerning the symptoms of ketoacidosis, a potentially life-threatening, late-stage T2D complication.
"One of the main reasons for this disparity in knowledge is probably the behavior of health professionals and the areas that are prioritized when informing patients," Lopes Ferreira explained.
Equipping patients with knowledge
The researchers found that the use of medication was one factor that impacted T2D knowledge. The percentage of correct answers was 51.8 pre cent for non-insulin treated patients, and 58.7 per cent for patients using insulin. Looking at socioeconomic and demographic factors, being younger than 65 years, having a higher education, not living alone, and following a specific diet had a positive impact on disease knowledge.
The researchers said that their results highlight the need to improve T2D knowledge about certain aspects of the disease, for example, blood sugar monitoring, which can help to avoid spikes in blood sugar levels that are associated with acute and chronic complications. Knowledge gaps within individual sections of the test are also something that needs to be addressed urgently, the team pointed out.
They also stated that studies with even more participants could help to better understand the role of the socioeconomic and clinical determinants of the disease. "We focused on patients' own knowledge of their disease, rather than disease management being based solely on biological indicators. We hope that the results obtained will allow professionals to change the way they inform patients," Lopes Ferreira concluded. (ANI)
