A new series of articles published in The Lancet and The Lancet Diabetes and Endocrinology sheds light on the alarming rise of diabetes worldwide and the disparities in its impact. According to the research, diabetes is becoming increasingly prevalent and is expected to affect over 1.3 billion people by 2050.

The series emphasises how geographic disparities and structural racism faced by minority ethnic groups in low- and middle-income countries (LMICs) contribute to the rising rates of diabetes. By 2045, more than three-quarters of adults with diabetes will reside in LMICs, but fewer than 1 in 10 will receive proper guideline-based care. In high-income countries like the USA, diabetes rates are disproportionately higher among minority ethnic groups due to structural racism.

The research reveals that marginalised communities have limited access to essential diabetes medications, resulting in worse blood sugar control, lower quality of life, and reduced life expectancy. The COVID-19 pandemic has further exacerbated these disparities, with people with diabetes, especially those from ethnic minority groups, being more susceptible to severe infection and death.

To address these inequalities, the authors emphasise the importance of real-world interventions and high-quality research. They call for interventions that involve the affected communities and tackle the structural and social determinants of health. Examples of successful interventions include improving insulin access in sub-Saharan Africa and implementing community healthcare worker programmes in the USA.

The series underscores the urgent need for action to transform diabetes care and outcomes for marginalised populations worldwide. Without concerted efforts to address disparities in diabetes, the health of future generations will be at risk. The authors urge increased research funding and the development of effective measures to achieve equitable diabetes care and outcomes.
