Screening for diabetes in the adult population above the age of 20years among inhabitants of rural agricultural and rural desert areas of Egypt.

Abstract

The present study focused on identifying the current prevalence of diabetes mellitus (DM) in rural desert and rural agricultural areas of Egypt and comparing these findings to those of previous studies that reported lower prevalence rates of DM in rural desert versus rural agricultural areas. The study included a total of 15,000 participants aged 20years or older; 10,000 were from rural agricultural areas and 5000 were from rural desert areas in Egypt. The prevalence of DM and impaired fasting glucose for each group was recorded, participants were interviewed, medical history was obtained, physical examinations were performed, and fasting plasma glucose was used for diagnosis of DM and IFG using American Diabetes Association criteria. The prevalence of DM was 12.7% in agricultural areas and 4.7% in desert areas. The prevalence of newly diagnosed cases was 15.8% and 9.9% in agricultural and desert areas, respectively. The prevalence of IFG was 11.14% in agricultural and 8.04% in desert areas. These results suggest that living in a rural area makes patients at a higher risk of developing DM (OR = 2.968 CI (2.570-3.428) p < 0.001) and IFG (OR = 1.43, CI (1.272-1.616), p < 0.001). Logistic regression analysis revealed that increased age, living in agricultural areas, higher body mass index and positive family history of diabetes were the significant predictors affecting the prevalence of DM. The prevalence of DM, IFG, and overall dysglycemia (DM + IFG) in Egypt has generally increased in rural areas, with a lower prevalence in rural desert compared to rural agricultural areas.
