The delivery of obesity interventions to children and adolescents with physical disabilities: a systematic review

Background To examine the process and mechanisms of delivering obesity interventions to physically disabled children/adolescents. Methods PubMed, Medline, CINAHL Plus, Embase, Cochrane Library, Google Scholar, ClinicalTrials.gov, Science Direct were systematically and manually searched for studies conducted in physically disabled children/adolescents (0-18 years). Included interventions were physical activity, diet and obesity prevention education. Included outcomes were body mass index (BMI)/weight and obesity prevention knowledge. The Mixed Methods Appraisal Tool aided methodological quality assessments. Data were extracted and delivery models were synthesized and narratively summarized using the social ecological model. Results Seven studies of low (n = 4) and moderate (n = 3) scoring on methodological quality were eligible for inclusion. Study duration was 5 months or less (n = 5), 8 months (n = 1) and 2 years (n = 1). Interventions were delivered at home, school, hospital and rehabilitation centre through the internet, face-to-face and parents. No intervention was delivered at three or more levels of individual, interpersonal, institutional or community levels. No study reported significant outcomes on reduction in BMI/weight, or increase in obesity prevention knowledge. Conclusions Evidence reviewed in this study shows that obesity interventions for physically disabled children/adolescents lack both in delivery and design. Gaps revealed should be considered when developing interventions for this special population.
