Background: Diabetes has emerged as a global pandemic. It is one of the leading causes of death worldwide. This study was conducted to evaluate the trend of prevalence of diabetes in different age groups and understand the changing pattern in the age of onset of type 2 diabetes mellitus.
Materials and Methods: This was a retrospective, observational study carried out in type 2 diabetes patients coming to OPD for a period of 1 year from 1st January 2018 to 31st December 2018. The age of onset and year of onset of diabetes were noted. The data was analyzed and presented in the form of
graphs and charts.
Results: A total of 976 patients with type 2 diabetes who visited OPD during the study duration were included in the study. Maximum number of patients were diagnosed in the years 2011-2015 (n = 318, 32.58%). There is an increasing trend of prevalence over the years. The average age of onset during 1991-
1995 was 48.53 years which gradually decreases to 42.70 years in 1996-2000, followed by 41.98 years in 2001-2005, 39.5 years in 2006-2010, 35.79 in 2011-2015 and 36.14 in 2016-2018. Thus, there is a decreasing trend in the age of onset of T2DM.
Conclusion: The prevalence of T2DM is increasing and the age of onset is decreasing. Both the factors decrease the productivity years in the life of patient. This ultimately affect the economy of a country. Hence, measures should be taken to actively modify the lifestyle and improve the health of the population as a whole to fight against this tsunami of diabetes mellitus.
