Global diabetes cases grow four-fold in the last 30 years: The Lancet

The number of adults living with diabetes worldwide has surpassed 800 million, more than quadrupling since 1990, according to new data released in The Lancet on World Diabetes Day (November 14). 

The analysis, conducted by the NCD Risk Factor Collaboration (NCD-RisC) with support from the World Health Organization (WHO), highlights the scale of the diabetes epidemic and an urgent need for stronger global action to address both rising disease rates and widening treatment gaps, particularly in low- and middle-income countries (LMICs). 

Global diabetes prevalence in adults rose from 7% to 14% between 1990 and 2022. LMICs experienced the largest increases, where diabetes rates have soared while treatment access remains persistently low. This trend has led to stark global inequalities: in 2022, almost 450 million adults aged 30 and older – about 59% of all adults with diabetes – remained untreated, marking a 3.5-fold increase in untreated people since 1990. Ninety per cent of these untreated adults are living in LMICs.

The study further reveals substantial global differences in diabetes rates, with the prevalence of diabetes among adults aged 18 and older around 20% in the WHO South-East Asia and the Eastern Mediterranean Regions. These two regions, together with the African Region, have the lowest rates of diabetes treatment coverage, with fewer than 4 in 10 adults with diabetes taking glucose-lowering medication for their diabetes.

According to WHO Director-General Dr Tedros Adhanom Ghebreyesus, “We have seen an alarming rise in diabetes over the past three decades, which reflects the increase in obesity, compounded by the impacts of the marketing of unhealthy food, a lack of physical activity and economic hardship. “To bring the global diabetes epidemic under control, countries must urgently take action. This starts with enacting policies that support healthy diets and physical activity, and, most importantly, health systems that provide prevention, early detection and treatment.” 

To address the soaring diabetes burden, WHO is also launching a new global monitoring framework on diabetes.  This product represents a crucial step in the global response, providing comprehensive guidance to countries in measuring and evaluating diabetes prevention, care, outcomes and impacts. By tracking key indicators such as glycaemic control, hypertension and access to essential medicines, countries can improve targeted interventions and policy initiatives. This standardized approach empowers countries to prioritize resources effectively, driving significant improvements in diabetes prevention and care.
