Diabetes mellitus,metabolic syndrome,and physical activity among Ethiopians: A systematic review

Background and aimsThe incidence of diabetes mellitus (DM) is increasing worldwide, and there is growing appreciation for the impact of limited physical activity on the disease. This study aimed to determine whether the current research on DM in Ethiopia has sufficiently identified and focused on the importance of limited physical activity according to the Global Physical Activity Questionnaire (GPAQ) in the disease etiology.MethodsThis was a systematic review, performed according to the PRISMA checklist. We searched primary studies of diabetes, diabetes-related complications, determinants, and magnitude of related morbidities in Ethiopia in PubMed, Medline, and ISI Web of Science databases. Reviews, editorial communications, reports, and letters were excluded.ResultsAmong 363 articles that were identified from all databases, 28 were included. It was found that 39% of the studies measured and included limited physical activity as a predisposing lifestyle factor in diabetes, while 17.86% either did not report or did not include this variable at all. Although 42.86% of the studies identified limited physical activity as an etiological factor in diabetes, it was not measured according to the GPAQ guidelines.ConclusionsThese data suggest that Ethiopian researchers do not give sufficient attention to the role of physical activity and its definition per GPAQ as a preventative factor for reducing the severity of diabetes symptoms. We suggest that physical activity research and promotion should be advocated in Ethiopia, and that researchers should seek advice on how to re-frame their work in the future.
