Study –
Diabetes cases are becoming more and more common around the world
The frequency of diabetes has doubled worldwide over the past thirty years. A trend which primarily affects less wealthy countries, shows a study published Wednesday in “The Lancet”.
Researchers estimate that more than 800 million people have diabetes, up from fewer than 200 million in the early 1990s.

According to this work, carried out by compiling a large number of studies previously carried out in most countries in the world, diabetes will affect around 14% of adults worldwide in 2022, compared to around 7% in 1990.
Taking into account the increase in the population, researchers estimate that more than 800 million people have diabetes, compared to less than 200 million in the early 1990s.
These figures include the two main forms of diabetes: type 1, which affects patients from a very young age and is often more difficult to treat because it is directly caused by an insulin deficiency, and type 2, which strikes relatively elderly people due to loss of insulin sensitivity.
1 in 3 Pakistani women are diabetic
Behind these global estimates, the reality is different depending on the country. In rich countries, such as those of Western Europe or Japan, the frequency of diabetes tends to stabilize, or sometimes even decline slightly.
On the other hand, “the burden of diabetes (…) is increasingly shifting to low- or middle-income countries,” note the researchers. For example, almost a third of Pakistani women are now diabetic, compared to less than a tenth in 1990.
Researchers particularly emphasize that type 2 diabetes tends to progress in countries where obesity is increasingly common, as is poor diet.
Inequalities in care
They also emphasize inequalities in treatment. While diabetes is increasing in less wealthy countries, this is not necessarily the case for the share of the population being treated for the disease.
Thus, in sub-Saharan Africa, the authors estimate that only 5% to 10% of adults with diabetes benefit from treatment.
Although some developing countries, such as Mexico, are performing well in population treatment, the general trend is toward “an ever-widening global gap between diabetes prevalence and its treatment,” the authors conclude. .
