An Investigation of the Effect of Latitude on the Incidence of Type ۱ Diabetes: A SystematicReview

Introduction: Type ۱ diabetes is an autoimmune disorder that causes the progressive destruction of beta cellsin the pancreas. Numerous epidemiological studies have demonstrated the prevalence of this disease amongvarious age groups, ethnicities, and geographic locations around the globe. The purpose of this study was toinvestigate the effect of latitude on the incidence of type ۱ diabetes in light of its high prevalence, which hascaused a variety of problems for children and adolescents, and the rise in prevalence of this disease worldwide.Methods: Using a predetermined search strategy, the ISI, Pubmed, Proquest, and Willey databases werecombed for all epidemiological studies conducted in Iran and the rest of the world up until ۲۰۲۲. Following thesearch, ۸۷۱ articles were located. After removing duplicates and screening the title, abstract, and main text, ۲۰۰articles were extracted, and finally ۲۰ articles were selected for the study.Results: Studies published up to ۲۰۲۲ were looked at, and it was found that there is a positive correlationbetween type ۱ diabetes and increasing latitude. It means that the number of people with diabetes goes up thefarther away from the equator you are.Conclusion: Given that geographic and environmental factors play a significant role in the etiology of diseases,it can be beneficial for research if decision-makers in the health and sanitation sectors pay attention to thesefactors. Additionally, planning in the health and sanitation sector can be done for each region following theclimatic, environmental, geological, etc. conditions of that region
