Are formal self-care interventions for healthy people effective? A systematic review of the evidence

INTRODUCTION: Preventative interventions are shown to be effective in reducing 40% of the mortality due to unhealthy behaviours and lifestyles. Health-promoting self-care has been recognised as a promising strategy in preventative health. However, self-care research is being done around the self-management of chronic illnesses and the promotion of self-care practices among healthy populations has been overlooked by many healthcare systems. METHOD: The study methodology was a systematic review with a narrative synthesis. The search was done through seven academic databases, reference tracking of selected articles and grey literature. The scoping, selection, screening and quality assessments of the articles were reviewed independently by two reviewers. RESULTS: Sixteen studies met the inclusion criteria. Self-care behaviour, health-promotive lifestyle changes and medical care utilisation were some of the main outcomes evaluated in the studies. Positive effects were seen in increasing self-care and health-promotive behaviours in most interventions although limited or mixed impact was seen in health attitudes, beliefs and utilisation of medical services. Most studies were from high income settings with low-quality study designs. The complexity of the word ‘self-care’ and inconsistencies in the terminology used in health-promotive self-care were significant highlights of the study. CONCLUSION: Health-promoting preventative self-care interventions show promise in increasing the well-being of healthy people. However, the methodological drawbacks limit the generalisability of the findings. As the demand for self-care interventions increases, the lack of a formal globally accepted definition and framework and complexity of behaviour change are key limitations to consider moving forward.
