Is the success of the SLIMMER diabetes prevention intervention modified by socioeconomic status? A randomised controlled trial.

Aim: To explore the role of socioeconomic status (SES) in participation, programme attendance, programme acceptability, adherence to lifestyle guidelines, drop-out, and effectiveness in the SLIMMER diabetes prevention intervention.

Methods: SLIMMER was a randomised controlled intervention, carried out in a real-world setting, targeting 40- to 70-year-old adults at increased risk of developing type 2 diabetes (n=316). The intervention group participated in a 10-month combined dietary and physical activity programme.

Process evaluation of a randomised controlled trial of a diabetes prevention intervention in Dutch primary health care: the SLIMMER study.

Objective: To investigate (i) how the SLIMMER intervention was delivered and received in Dutch primary health care and (ii) how this could explain intervention effectiveness.

Design: A randomised controlled trial was conducted and subjects were randomly allocated to the intervention (10-month combined dietary and physical activity intervention) or the control group. A process evaluation including quantitative and qualitative methods was conducted.

Using the intervention mapping protocol to develop a maintenance programme for the SLIMMER diabetes prevention intervention.

Background: Although lifestyle interventions have shown to be effective in reducing the risk for type 2 diabetes mellitus, maintenance of achieved results is difficult, as participants often experience relapse after the intervention has ended. This paper describes the systematic development of a maintenance programme for the extensive SLIMMER intervention, an existing diabetes prevention intervention for high-risk individuals, implemented in a real-life setting in the Netherlands.

Methods: The maintenance programme was developed using the Intervention Mapping protocol.

Feasibility and potential impact of the adapted SLIM diabetes prevention intervention in a Dutch real-life setting: the SLIMMER pilot study.

Objective: Pilot-testing of the adapted Study on Lifestyle intervention and Impaired glucose tolerance Maastricht (SLIM) and to determine its feasibility and likelihood of achieving desired impact.

Methods: Pilot intervention study (a 10-month combined lifestyle intervention) using a one group pre-test post-test design with on-going process measures (i.e.

SLIMMER: a randomised controlled trial of diabetes prevention in Dutch primary health care: design and methods for process, effect, and economic evaluation.

Background: Implementation of interventions in real-life settings requires a comprehensive evaluation approach. The aim of this article is to describe the evaluation design of the SLIMMER diabetes prevention intervention in a Dutch real-life setting.

Methods/design: The SLIMMER study is a randomised, controlled intervention study including subjects aged 40 through 70 years with impaired fasting glucose or high risk of diabetes.

Adapting the SLIM diabetes prevention intervention to a Dutch real-life setting: joint decision making by science and practice.

Background: Although many evidence-based diabetes prevention interventions exist, they are not easily applicable in real-life settings. Moreover, there is a lack of examples which describe the adaptation process of these interventions to practice. In this paper we present an example of such an adaptation.

Translating the SLIM diabetes prevention intervention into SLIMMER: implications for the Dutch primary health care.

All over the world, prevalence and incidence rates of type 2 diabetes mellitus are rising rapidly. Several trials have demonstrated that prevention by lifestyle intervention is (cost-) effective. This calls for translation of these trials to primary health care.
