Global diabetes rate has doubled in the past 30 years
The percentage of adults suffering from diabetes across the world has doubled over the past three decades, with the biggest rises coming in developing countries, a study revealed.
Growing Concern
According to a new report published in The Lancet journal, the health condition affected around 14% of adults worldwide in 2022, compared with 7% in 1990. This significant rise is attributed to the growing population, increased obesity rates, and an unhealthy diet. Researchers estimate that more than 800 million people are now diabetic, compared to under 200 million in 1990.
Analysis and Findings
The study, conducted by scientists from NCD Risk Factor Collaboration in collaboration with the World Health Organisation, analyzed data from over 140 million people aged 18 or older, collected through more than 1,000 studies globally. The data showed a significant rise in diabetes prevalence, particularly in low- and middle-income nations. National figures varied widely, with the rate of diabetes staying the same or even falling in wealthier countries such as Japan and Canada, as well as western European nations like France and Denmark.
Complications and Treatment
Behind the global numbers, uncontrolled diabetes can lead to serious health complications including hyperglycaemia (high blood sugar), which can damage blood vessels and nerves, affecting vital organs. Other complications include amputation, heart disease, kidney damage or vision loss, and even premature death.
The report highlights the widening gap in how diabetes is treated between richer and poorer countries, with three out of five people aged over 30 with diabetes – or 445 million adults – did not receive treatment in 2022. India alone was home to almost a third of that number, while in sub-Saharan Africa, only 5-10% of adults with diabetes received treatment that year.
Obesity and Nutrition
The scientists emphasize that obesity is an “important driver” of type-2 diabetes, as is an unhealthy diet. They underscore the importance of addressing these underlying factors to combat the rising tide of diabetes cases.
Conclusion
The study is a stark reminder of the urgent need to address diabetes and its complications globally, particularly in low- and middle-income countries. Increased efforts are needed to develop and implement effective treatment options, as well as preventative measures, to reduce the burden of diabetes on these nations and their populations.
FAQs
What is the current diabetes rate worldwide?
Around 14% of adults worldwide are affected by diabetes, compared to 7% in 1990.
Has diabetes prevalence increased in developed countries?
In developed countries, the prevalence of diabetes has stayed the same or even fallen in some cases, such as Japan, Canada, western European nations like France, and Denmark.
What is the main type of diabetes?
The two main types of diabetes are type-1 and type-2 diabetes. Type-1 primarily affects young people and is more difficult to treat. Type-2 mainly affects middle-aged or older adults who lose their sensitivity to insulin.
Is diabetes treatment available globally?
No, a significant gap exists in treating diabetes globally, with some countries providing treatment to few adults with diabetes, including in sub-Saharan Africa and India, where only a small percentage of adults receive treatment.
How can I prevent diabetes?
Maintaining a healthy diet, exercising regularly, and avoiding obesity are important measures to prevent or delay the onset of diabetes.
