Abstract:Objective To investigate the prevalence and classification of cataract and their influencing factors in type 2 diabetes patients aged 50 years and above in Jinhua City, and to provide a basis for prevention and treatment of cataract among people with type 2 diabetes. Methods A cross-sectional study and stratified cluster random sampling method were used in this analysis. 2,569 diabetes patients were selected from 17 basic sampling units in Wucheng District of Jinhua City to serve as the studysubjects, and their general information and diabetes related information were collected through a questionnaire survey. Fundus examinations were made by ophthalmologists and technicians, and cataract diagnosis was performed. Multivariate logistic regression analysis was conducted to identify the factors related to cataract in the diabetes patients. Results A total of 2,156 diabetes patients were actually enrolled into the study (with a response rate of 83.92%). A total of 391 (18.14%) cataract patients were detected, including 307 cases of nuclear cataract (78.52%), 47 cases of cortical cataract (12.02%), 5 cases of posterior subcapsular cataract (1.28%), and 32 cases of mixed cataract (8.18%). The results of multivariate logistic regression analysis displayed that diabetes patients aged 60-69 years and70 yearsand abovehad an increased risk of developing cataract (OR=1.210, 95%CI:1.028-1.423; OR=1.419, 95%CI:1.151-1.751) compared with ones aged 50-59 years. Male diabetes patients were at a higher risk of having cataract compared with female ones (OR=1.239, 95%CI:1.036-1.481). Diabetes patients with hypertension had a higher risk of having cataract compared with ones without hypertension (OR=1.436, 95%CI:1.102-1.871).Diabetes patients with underweight, overweight and obesity had a higher risk of suffering from cataract (OR=1.466, 95%CI: 1.084-1.982; OR=1.362, 95%CI:1.126-1.647; OR=1.345, 95%CI:1.053-1.718) compared with ones with normal BMI. Diabetes patients having the course of disease with 5-9 years and 10 years and above ran a higher risk of getting cataract (OR=1.848, 95%CI:1.475-2.315; OR=2.130, 95%CI:1.200-3.783) compared with ones having the course of disease less than 5 years. Diabetes patients with fasting blood glucose levels of 6.1-7.9 mmol/L and ≥8 mmol/L ran a higher risk of getting cataract (OR=1.829, 95%CI:1.075-3.111; OR=2.171, 95%CI:1.124-4.194) compared with ones with fasting blood glucose level <6.1 mmol/L. Conclusion The prevalence rate of cataract was higher in diabetes patients aged 50 years and above than in non diabetes population.The results suggest that special attention should be paid to diabetes patients with long disease course, advanced age and hypertension.It is of great significance for reducing the occurrence of cataract to strengthen the regular screening of cataract and enhance the control of blood sugar and blood pressure.
