Study context and justification EpidemiologyGlobal age-standardised diabetes prevalence increased from 4.3% in 1980 to 9% in 2014 in men, and from 5% to 7.9% in women. 5 In 2019, worldwide prevalence is estimated to be 9.3%. The geographic distribution of the disease shows that it is no more specific to developed countries (prevalence of 10.4%). 1 On the contrary, the prevalence of diabetes has increased faster in low income countries (4%) and middle income countries (9.5%). 1,5 79% of adults with diabetes are living in low-and middle-income countries and in Africa alone 19.4 million of people are living with diabetes, 60% of cases are undiagnosed and 73.1% of deaths due to diabetes occur in people under age of 60 years, compared to only 31.4% in Europe. 1 These premature deaths reduces the workforce and has a negative impact in the economy as stipulated by Boomer et al. 6 in their diabetes indirect costs estimation.Diabetes is a major cause of many complications such as retinopathy and cataract (ultimately leading to blindness), kidney failure, sexual dysfunction, heart attack, stroke, diabetic neuropathy and lower limbs amputation. 4 But one of the largest studies (pool of 628) in Cameroon has shown that the mortality of type 2 diabetes is high and most of the diabetic patients dies from acute metabolic complications (22.2%). 7 With this exponential rise, diabetes was already the 7th deadliest disease in the world in 2016. 8 According to new data from the IDF, 1 the number of people with diabetes is expected to rise to 700 million by 2045. These statistics are a real issue for global health system agencies and governments in many countries, which is why diabetes has become a major public health
