Diabetes affects almost one in 10
Diabetes is rapidly emerging as one of the world’s most serious public health problems, affecting almost 500 million adults and contributing to the deaths of close to four million people a year.
An alarming report from the World Health Organization has found that incidence of diabetes, once mainly confined to high income countries, is rapidly spreading, and by 2014 422 million adults were living with the disease – almost one in every 10 adults worldwide. In 1980, its prevalence among adults was less than 5 per cent.
WHO Director-General Dr Margaret Chan said the disease’s emergence in low- and middle-income countries was particularly problematic because they often lacked the resources to adequately diagnose and manage the disease, resulting in needless complications and premature deaths.
According to the WHO’s Global Report on Diabetes, the condition was directly responsible for 1.5 million deaths in 2012 and contributed to a further 2.2 million fatalities by increasing the risk of cardiovascular and other diseases.
Diabetes takes a relatively heavy toll of younger people, particularly in less wealthy countries. Of the 3.7 million deaths linked to diabetes in 2012, 43 per cent occurred in people younger than 70 years of age, and the proportion was even higher in low- and middle-income countries.
The rise in diabetes has coincided with an increase in associated risk factors, most particularly a jump in global rates of overweight and obesity. Currently, 10.8 per cent of men and 14.9 per cent of women worldwide are considered to be obese, and on current trends that will increase to 18 per cent of men and 21 per cent of women by 2025.
While rates of obesity and diabetes are continuing to climb in rich countries, the WHO said this is being outstripped in other parts of the world, particularly middle-income nations.
The relative lack of resources to prevent, diagnose and manage diabetes in less wealthy countries is exacerbating its spread and impact.
Programs and policies to encourage physical activity, promote health diets, avoid smoking and controlling blood pressure and lipids are generally better funded in rich countries, where GPs and other frontline health services are better equipped to detect diabetes early and patients generally have good access to insulin and other treatments.
The WHO said that even though most countries have national diabetes policies in place, often they lack for funding and implementation.
“In general, primary health care practitioners in low-income countries do not have access to the basic technologies needed to help people with diabetes properly manage their disease,” the agency said. “Only one in three low- and middle-income countries report that the most basic technologies for diabetes diagnosis and management are generally available in primary health care facilities.”
In particular, it highlighted serious problems with access to treatments.
“The lack of access to affordable insulin remains a key impediment to successful treatment and results in needless complications and premature deaths,” the WHO report said. “Insulin and oral hypoglycaemic agents are reported as generally available in only a minority of low-income countries. Moreover, essential medicines critical to gaining control of diabetes, such as agents to lower blood pressure and lipid levels, are frequently unavailable in low- and middle-income countries.”
Diabetes has been identified as one of four priority non communicable diseases targeted under the 2030 Agenda for Sustainable Development, but Dr Chan said the WHO report showed there was “an enormous task at hand”.
“From the analysis it is clear we need stronger responses not only from different sectors of government, but also from civil society and people with diabetes themselves, and also producers of food and manufacturers of medicines and medical technologies,” the WHO leader said.
