Purpose of reviewChronic respiratory diseases are a leading cause of morbidity and mortality in low-income and middleincome countries (LMICs). We aim to review prevalence of respiratory diseases and related symptoms, which contribute significantly to burden of disease in LMICs. We report global estimates of respiratory problems amongst adults in LMICs and recent findings relating to community prevalence and impact of respiratory problems. We conclude by identifying research priorities for improved recognition and palliation of respiratory problems.
Recent findingsWe report findings from 16 studies, highlighting key issues relevant to burden of respiratory problems in LMICs. COPD and associated symptoms are identified as important drivers of increasing respiratory problems in LMICs, with an estimated prevalence of 7.2%. Negative impacts of respiratory diseases include: reduced physical function (capacity to work), quality of life (depression; anxiety) and socioeconomic wellbeing (healthcare costs; earning potential). Locally appropriate palliative care interventions may improve quality of life without increasing costs.
