Diabetes complications

The association of physical activity and sedentary behaviour with the development and progression of microvascular complications in type 1 and type 2 diabetes: A systematic review of cohort studies

Diabetes Res Clin PractPublished systematic review of cohort studies

Authors' conclusion

Higher PA was associated with some favourable longitudinal microvascular outcomes, mainly in T2D, but residual confounding, self-reported exposures and heterogeneous outcomes limit interpretation. Evidence on SB was restricted to one small cohort and cannot establish its association with incident microvascular complications.

Study context

Population
Adults with type 1 (T1D) or type 2 diabetes (T2D); prospective or retrospective cohort studies comparing physical activity (PA) or sedentary behaviour (SB) levels in relation to retinopathy, nephropathy, neuropathy or severe neuropathy-related foot outcomesstudies included (nine prospective and three retrospective), reported sample sizes summed to 2.55 million, participants not necessarily unique · prospective studies nine · retrospective studies three

  • First diabetic foot ulcer (SB evidence, one cohort of 175 participants with established diabetic peripheral neuropathy): Evidence on SB was restricted to one cohort of 175 participants

Renal, neuropathic and retinopathy outcomes with higher PA

Higher PA was associated with lower risk of several renal and neuropathic outcomes, predominantly in T2D
Retinopathy findings varied
