Acting on non-communicable diseases in low- and middle-income tropical countries

Abstract

The classical portrayal of poor health in tropical countries is one of infections and parasites, contrasting with wealthy western countries, where unhealthy diet and behaviours cause non-communicable diseases (NCDs) like heart disease and cancer. Using international mortality data, we show that most NCDs cause more deaths at any age in low- and middle-income tropical countries than in high-income western countries. Causes of NCDs in low- and middle-income countries include poor nutrition and living environment, infections, insufficient regulation of tobacco and alcohol, and under-resourced and inaccessible healthcare. We identify a comprehensive set of actions across health, social, economic and environmental sectors that can confront NCDs in low- and middle-income tropical countries and reduce global health inequalities.
