Number of adults with diabetes has quadrupled since 1980, South-east Asia 2nd-most affected region: WHO

The WHO has reported that there are about 422 million adults living with diabetes as of 2014, most of whom have type 2 diabetes, which is associated with obesity.

GENEVA (AFP) - The number of adults estimated to be living with diabetes surged to 422 million by 2014, a nearly fourfold increase on 1980 figures, the World Health Organization (WHO) said on Wednesday (April 6), in its first-ever global report on the disease, which also named South-east Asia the region second-most affected.

"Globally, an estimated 422 million adults were living with diabetes in 2014, compared to 108 million in 1980," the United Nations health agency said, warning that the condition had spread because of worldwide changes "in the way people eat, move and live".

The disease directly caused 1.5 million deaths in 2012, but elevated blood glucose levels linked to diabetes were responsible for an additional 2.2 million deaths that year, the report said.

The region worst affected, with 131 million estimated cases in 2014, was the WHO's Western Pacific region, which includes China and Japan.


The South-east Asia region - which includes heavily populated India and Indonesia - was the next most affected, with 96 million cases.

Europe and the Americas were third and fourth on the list, with 64 million and 62 million cases respectively.

Diabetes is divided into two types. There is no known way to prevent type one, which occurs when the pancreas does not produce enough insulin.

Most people living with diabetes have type 2, which is associated with obesity and other lifestyle factors and emerges in adults and increasingly among children.

To curb the intensifying burden of the disease, huge efforts were needed to change global "eating and physical activity habits", especially early in life, when key behavioural patterns are formed, the WHO said.

"There is a critical window for intervention to mitigate the risk of obesity and type 2 diabetes later in life," the report said.

It noted that spreading consumption of sugary drinks and other fattening foods was a key factor, but drew particular attention to high rates of physical inactivity.

According to worldwide 2010 figures, nearly a quarter of people over 18 did not do the minimum recommended amount of physical activity per week, with women recorded as less active than men.

The WHO recommends that adults get at least 150 minutes of moderate physical activity, including things like walking, jogging and gardening, per week.

"Physical inactivity is alarmingly common among adolescents," the report added, noting that the excessively sedentary lifestyles were more acute in high-income countries than low income countries.

The WHO estimated that the annual global cost of diabetes, including health care needs, exceeds US$827 billion (S$1.1 trillion).

Citing a separate study, the agency said the global GDP losses linked to diabetes could reach US$1.7 trillion by 2030, with the damage split roughly evenly between developed and developing nations.

Noting both the health and macroeconomic damage caused by the growing diabetes epidemic, WHO chief Margaret Chan called for a coordinated, holistic response.

Like with obesity, the WHO has stressed that putting excessive blame on individuals for eating too much or not exercising enough ignored several key factors, including the obstacles to eating healthily in several societies.

"Effectively addressing diabetes does not just happen: it is the result of collective consensus and public investment in interventions that are affordable, cost-effective and based on the best available science," Dr Chan said in a statement.
