Research and the health of indigenous populations in low- and middle-income countries.

In low- and middle-income countries (LMICs)-when there are available data-a 'health divide' exists between indigenous and non-indigenous populations living in the same society. Despite the limited available evidence suggesting that indigenous populations have high levels of health needs, there is scant research on indigenous health, especially in Africa, China and South Asia. Pursuing research, however, is clouded by the prior negative experiences that indigenous populations have had with researchers. In this paper, we describe the current evidence base on indigenous health in LMICs, propose practical strategies for undertaking future research, and conclude by describing how global health researchers can contribute to improving the health of indigenous populations.
