Diabetes and age at onset of diabetes were obtained from reports made at five home visits at age 36, 43, 53, 60-64 and 68-70, and from the response to a postal questionnaire at 31 years which indicated that the cohort member had an onset of physician diagnosed diabetes. Type 1, Type 2 and gestational diabetes cases were distinguished based on age at diagnosis, medication history and the reasons documented.
Blood samples taken at 60-64 and 68-70 were tested for HbA1c, the most commonly-used biomarker for diabetes.

The metabolic syndrome at age 53 years and its components were defined using cut points recommended by ATPIII8 (2001). The ATPIII8 definition was modified to include glycated haemoglobin (HbA1c) instead of fasting plasma glucose, data for which were unavailable. Details of the cut points used are available on request.

The derived diabetes variables have been updated to take account of the most recent data collections.

Obtaining the standard diabetes variables

  • You can obtain a list of the standard topic variables to use in an NSHD data sharing request by selecting the link at the end of this page.
  • The XML version of the link can be sent to the LHA as part of a data sharing request.
  • Simply use your browser's Save As facility to save the list of variables to a file on your computer.
  • You can then email the XML version to us in support of your application, or when you fill in the data access application form and it asks which variables you need, mention the 'diabetes standard basket' along with any others.

Please note that the diabetes standard basket only contains a single variable - the overall summary measure for doctor diagnosis of this condition. However, much more information has been collected on the type of diabetes, date of diagnosis and how it is being managed, so you are advised to run a keyword search for 'diabetes' on sSylark to find out more.
