This systematic review set out to summarise previous trials of aerobic and resistance training.
In people from an ethnic minority with type 2 diabetes, what programmes are effective
The review was carried out in Australia and included people with African, Indian, Polynesian, Hispanic, Arabian, and Chinese ethnicity. It’s not clear whether the review looked for studies carried out in countries where the participants were an ethnic minority, or whether it also included studies on populations in countries where these ethnicities form the majority.
The reviewers found five randomised trials with 521 participants.
They did not attempt a meta-analysis but report a general consensus towards reductions in HbA1c, insulin action, body composition, blood lipids and systolic and diastolic blood pressure.
Users of this research should consider:
- Did they address a clearly focuse question? How did they define “high risk” patients? What outcomes were they interested in and did they specify them in advance?
- Was the search strategy comprehensive enough?
- Did they carry out blind, independent assessments of the relevance and quality of the individual studies?
- Heterogeneity. The study methods, quality, populations, interventions and outcomes were different from study to study: consider looking for individual high-quality trials in patients similar to yours.
