Overview

Systematic review of reviews reveals key components improving diet and physical activity in adults at risk of type 2 diabetes, highlighting self-regulation and combined lifestyle targets.

Key Points

To identify specific intervention components and characteristics associated with increased dietary and physical activity change among adults at risk of developing type 2 diabetes.
Searched MEDLINE, EMBASE, CINAHL, PsycInfo, and the Cochrane Library (1998–2008) for systematic reviews of diet and physical activity interventions in adults at risk of type 2 diabetes.
Identified 3856 articles, from which two independent reviewers selected 30 reviews and extracted 129 causal and associative analyses relating intervention components to effectiveness.
Interventions achieved clinically meaningful weight loss of 3–5 kg at 12 months and 2–3 kg at 36 months, alongside an increase of 30–60 minutes per week of moderate physical activity at 12–18 months.
Causal analyses demonstrated that intervention effectiveness increased when targeting both diet and physical activity simultaneously, engaging social support, and utilizing established behaviour change techniques.
Associative analyses showed effectiveness correlated with higher contact frequency and self-regulatory strategies (goal-setting and self-monitoring), while delivery provider, setting, and mode showed no clear association.
