Physical activity guidelines for adults with type 2 Diabetes: Systematic review

Aims

The aim of this study was to systematically review recommendations on physical activity for adults with type 2 diabetes (T2D).

Methods

Online databases were searched for clinical practice guidelines (CPGs), statements, and recommendations. Two authors screened the guidelines based on eligibility criteria. FITT (Frequency, Intensity, Time, Type) for physical activity and disease-specific precautions were extracted independently. The methodological quality of CPGs was assessed using the AGREE II instrument. Recommendations were categorized according to FITT, with disease-specific adaptations also recorded.

Results

Fifteen guidelines were included. Nine underwent AGREE II evaluation, with three rated high quality and the rest moderate to low. The predominant recommendation was to engage in at least 150 min of moderate aerobic exercise per week. Adaptations for T2D focused on glucose levels, diet, foot care, weather conditions, sedentary behaviour, neuropathy, and retinopathy.

Conclusion

While guidelines consistently recommended aerobic exercise, there was limited emphasis on strength and flexibility exercises. Significant limitations in methodological and reporting quality were noted, especially in stakeholder involvement and applicability. Future guidelines should use a standardized FITT framework and adhere to standard development methods to enhance usability for healthcare professionals and patients.
