Introducing the PLOS special collection of economic cases for NCD prevention and control: A global perspective.

Noncommunicable diseases (NCDs), such as heart disease, cancer, diabetes, and chronic respiratory disease, are responsible for seven out of every 10 deaths worldwide. While NCDs are associated with aging in high-income countries, this representation is often misleading. Over one-third of the 41 million annual deaths from NCDs occur prematurely, defined as under 70 years of age. Most of those deaths occur in low- and middle-income countries (LMICs) where surveillance, treatment, and care of NCDs are often inadequate. In addition to high health and social costs, the economic costs imposed by such high numbers of excess early deaths impede economic development and contribute to global and national inequity. In higher-income countries, NCDs and their risks continue to push health care costs higher. The burden of NCDs is strongly intertwined with economic conditions for good and for harm. Understanding the multiple ways they are connected-through risk factor exposures, access to quality health care, and financial protection among others-will determine which countries are able to improve the healthy longevity of their populations and slow growth in health expenditure particularly in the face of aging populations. The aim of this Special Collection is to provide new evidence to spur those actions
