The epidemiology of breathlessness
Breathlessness is a prevalent issue reported in the general population, increasing with advancing age. A variety of analyses have been undertaken to characterise the epidemiological characteristics and demographic patterns of this important symptom. There are several methodological factors that should be considered when assessing the available data in this area, and overall, there remains a paucity of high-quality and robust data. The aim of this chapter is to describe findings from the available published work in this field and to highlight the different approaches that have been used to assess this issue. The chapter addresses differences among populations, risk factors and changes in breathlessness across the lifespan. The chapter also covers health-related events that are associated with breathlessness and concludes by addressing unmet needs and future research priorities.
