ClinicalTrials.gov identifier
EudraCT number
Public title The European Diabetes Prevention Study
Scientific title Reducing the burden of non-insulin dependent diabetes mellitus: a randomised controlled trial of behavioural interventions to modify diet and physical activity in people with impaired glucose tolerance Also from June 2011: A follow-up at 10 years of participants in the Newcastle Arm of the European Diabetes Prevention Study who remain free of type 2 diabetes at 10 years from baseline, based of diagnoses from within the trial or subsequent General Practitioner diagnoses: to assess the difference in incidence of type 2 diabetes between the intervention and control arms of the original study
Acronym EDIPS-Newcastle. Also from June 2011: EDIPS2-Newcastle
Serial number at source 057146, N0565163209
Study hypothesis Reducing the burden of type two diabetes. To assess the effectiveness of a diet and exercise intervention programme to prevent or delay the onset of type two diabetes in people with Impaired Glucose Tolerance (IGT).

The null hypothesis is that there will be no difference in the proportions of intervention or control group subjects progressing to develop diabetes within five years.

Please note that due to continuing follow-up the end date of this trial has been extended to 31/07/2007. The previous anticipated end date of this trial was 31/12/2006.

Please note that as of 26/01/2009 this record was updated; due to further continuing follow-up the end date of this trial was extended to 31/12/2007. The initial anticipated end date of this trial was 31/12/2006.

Please not that from June 2011 the original EDIPS-Newcastle participants, who remained free from type 2 diabetes,have been invited to return for a follow-up assessment at ten years from their original recruitment date.

Participants for EDIPS-Newcastle were recruited from the UK. EDIPS-Newcastle is part of a European collaboration, participants in Finland have been recruited to the Finnish Diabetes Prevention study and participants in The Netherlands have been recruited to the SLIM study.
