### Question: Is prevalence of retinopathy related to the age of onset of diabetes?

### Context: 1: This is a population-based study for which 1,414 diabetics were recruited. The fundi were photographed using 45-degree 4-field stereoscopic digital photography. The diagnosis of DR was based on Klein's classification of the Early Treatment Diabetic Retinopathy Study scales.
2: The prevalence of DR was 33.3% (95% confidence interval, CI: 26.6-39.9) in known onset of diabetes (≤ 40 years) compared to 15.6% (95% CI: 13.6-17.6) in those with late onset (>40 years; p<0.0001). In the group with age of known onset of diabetes ≤ 40 years, the risk factors, associated with any DR, were poor glycemic control (odds ratio, OR: 1.36 for every g% increase in glycosylated hemoglobin), insulin use (OR: 4.21), increasing known duration of diabetes (OR: 1.10 for increase of every year in known duration of diabetes) and presence of macroalbuminuria (OR: 13.39). In the late onset of diabetes group, besides the above-mentioned risk factors, the presence of microalbuminuria (OR: 2.08), male gender (OR: 1.67), presence of anemia (OR: 1.89) and increased systolic blood pressure (OR: 1.01) were the risk factors for DR.


###Response: The prevalence of DR was almost twice more in those subjects who developed diabetes before the age of 40 years than those who developed it later.
