Abstract Background Poor appetite is common in older age, with estimated prevalence figures ranging between 15–30% in community-dwelling populations. Despite known links between poor appetite and adverse health outcomes, appetite is not routinely assessed and the causes and impact of appetite loss in older age are not well understood.
