Abstract
The study aims to explore the distribution characteristics and influencing factors of diabetic retinopathy (DR) in diabetes mellitus (DM) patients and association rules of eye diseases in these patients. Data were obtained from 1284 DM patients at Henan Provincial People’s Hospital. Association rules were employed to calculate the probability of the common occurrence of eye-related diseases in DM patients. A web visualization network diagram was used to display the association rules of the eye-related diseases in DM patients. DR prevalence in people aged < 40 years (≥ 58.5%) was higher than that in those aged 50–60 years (≤ 43.7%). Patients with DM in rural areas were more likely to have DR than those in urban areas (56.2% vs. 35.6%, P < 0.001). DR prevalence in Pingdingshan City (68.4%) was significantly higher than in other cities. The prevalence of DR in patients who had DM for ≥ 5 years was higher than in other groups (P < 0.001). About 33.07% of DM patients had both diabetic maculopathy and DR, and 36.02% had both diabetic maculopathy and cataracts. The number of strong rules in patients ≥ 60 years old was more than those in people under 60 in age, and those in rural areas had more strong rules than those in urban areas. DM patients with one or more eye diseases are at higher risks of other eye diseases than general DM patients. These association rules are affected by factors such as age, region, disease duration, and DR severity.
Highlights
The study aims to explore the distribution characteristics and influencing factors of diabetic retinopathy (DR) in diabetes mellitus (DM) patients and association rules of eye diseases in these patients
The results showed that of the DM patients, 426 (33.07%) had both diabetic maculopathy and DR, 464 (36.02%) had both diabetic maculopathy and cataracts, 326 (25.31%) had both diabetic maculopathy and optic atrophy
The results showed that: (1) among the included DM patients, the prevalence of DR varied with ages, regions, and DM durations, but there was no statistical difference in the prevalence of DR between males and females; (2) patients with one or more eye diseases are at a higher risk of other eye diseases than those in the general population, and these association rules are affected by age, disease duration, and grade of DR classification
Summary
The study aims to explore the distribution characteristics and influencing factors of diabetic retinopathy (DR) in diabetes mellitus (DM) patients and association rules of eye diseases in these patients. Association rules were employed to calculate the probability of the common occurrence of eye-related diseases in DM patients. DM patients with one or more eye diseases are at higher risks of other eye diseases than general DM patients These association rules are affected by factors such as age, region, disease duration, and DR severity. Multiple correspondence analysis and association rules were used to analyze the distribution characteristics of DR and determine its association rules with other eye diseases in DM patients These data provided a frame of reference for developing appropriate measures for better screening, diagnosis, and prevention of DR
