Diabetes is among the major risk factors of cardiovascular diseases. Published cohort studies about pre-diabetes and diabetes in the Middle East is very limited. The present study is the third prospective research on the evaluation of pre-diabetes and type 2 diabetes from the region that was carried out in Ahvaz, southwest of Iran.
The individuals aged over twenty years who had participated in the study on the prevalence of metabolic syndrome in 2009 (phase I) in Ahvaz were re-invited in 2014. The questionnaires were completed through interview and anthropometric parameters were measured according to standard protocols. The logistic regression was applied to define the variables affecting the incidence of pre-diabetes and diabetes and the risk probability.
In the median of five year continuous pursuit, 593 subjects participated in reexamination from which 396 individuals were non-diabetic in phase I. These people with average age of 38±13 during five years embrace 6.6% with type 2 diabetes (13.64 per 1000 person years) and 18.5% with pre-diabetes (40.8 per 1000 person years). Among the phase I participants with pre-diabetes, 16.8% were diagnosed with diabetes in a five year period. The factors affecting the incidence of pre-diabetes among people younger than 65 years include age, family history of diabetes, and gender. The factor of age plays vital role in the transformation of pre-diabetes to diabetes.
The city of Ahvaz with the average of 13.64 per 1000 person years with type 2 diabetes is one of the areas with high incidence of diabetes in Iran. Educational and preventive public health interventions are strongly recommended.
