I need a data set of diabetes patients suffering from diabetes complications like retinopathy kidney diseases and etc. dividing by patient age and sex in at least 25 years.
UCI Machine Learning Repository provides three datasets for diabetes:
- Diabetes Data Set
- Pima Indians Diabetes Dataset
- Diabetes 130-US hospitals for years 1999-2008 Data Set
If these don't meet your needs, you may want to go through the papers that cite these datasets and see what else they have used.
