Subsequent questions 501-508 establish age of diagnosis, type of diabetes/high sugar levels, whether the diabetes/high sugar levels are still current and long-term.

| ICD-9 codes | 250.0 |
| NHS codes used | . . | 079 | 689,948 |
| Notes | Cannot separate into types of diabetes. Add code 106 to include high sugar levels. | Need to select diabetes as a "current" condition. |  |
| Estimate '000 | . . | 173.4 | 433.8 |
| Standardised rate per 1,000 population(a) | . . | 10.2 | 22.9 |
| 95 % confidence intervals on standardised rates | . . | 8.5 - 11.9 | 21.0 - 24.8 |
| Comments | From 1995 to 2001 the level of reported type 2 diabetes has increased more than two-fold, while the level of unknown/unspecifed diabetes declined by 75%. These opposing trends have a degree of cancelling each other overall, but renders the type 2 time series not acceptable. |
