Analysis of prevalence and incidence trends of diabetes mellitus in Majmaah city, Riyadh Region, Saudi Arabia: A trend of 3 years retrospective study (2017-2019)

Abstract

Diabetes Mellitus (DM) remains a global disease and prevalent among 415 million people. Saudi Arabia is the second-highest country in the Middle East region and the seventh in the world in its prevalence rate. Population-based prevalence and incidence data are ultimate to evaluate the effects of prevention strategies for diabetes and such relevant studies in Saudi Arabia are scarce. Quantification of prevalence and incidence of DM is significant in rural-based populations to allow for clinical resource management. Therefore, this study is designed to determine the prevalence of diabetes among the population of Majmaah city, in the Riyadh region of Saudi Arabia in the past three years (2017-2019) and compare them with prevalence and incidence rates in Saudi Arabia. The data of patients with DM for the past three years were collected from archives of King Khaled hospital in Majmaah city and analyzed with different statistical methods frequency distribution using SAS software. DM's annual incidence (AI), incidence rate (IR), and average annual incidence (AAI) with confidence intervals of 95% are reported. It was found that incidence rates of both type 1 and type 2 DM of all age groups have increased in the last three years. The incidence rate of type 1 DM patients has increased by 20.23% while in type 2 DM has increased by 9.31%. Finally, this study suggested that DM trends among the population in Majmaah city are consistently increasing year by year and it is also in line with the trend of the whole Saudi Arabia irrespective of gender and age.
