Physical activity improves physiological, cognitive and psychosocial functioning in chronic non-communicable diseases (NCDs). This study reviewed papers on effects and patients' experiences of physical activity interventions for chronic NCDs in Africa.
We conducted a systematic review of clinical and qualitative studies by searching eight bibliographic databases and grey literature until April 19, 2017. The mixed-methods appraisal and Cochrane Collaboration’s tools were used for quality and risk of bias assessments. Three-stage sequential explanatory syntheses was done.
One randomised controlled trial (RCT), 2 non-controlled before-and-after studies, and 2 qualitative studies of diabetic South African and Reunion patients were included. Exercise and sports unrelated with home and occupational activities were increased in the long term (1 year: moderate quality evidence) and short term immediately after a 4-week intervention (low quality evidence). There was conflicting evidence of intervention effects on home and occupational physical activities. Behaviour change techniques improving chronic disease knowledge, addressing environmental barriers and stimulating/supporting physical activity were important to patients. Procedure-related components – health professional training and adequate health facility were important to patients but were not addressed.
High quality RCTs are needed to confirm the intervention components for improving physical activity for chronic NCD management in Africa.
