They are also adversely affected by the underlying determinants of health, such as access to safe drinking water, sanitation, adequate housing and nutrition. Additionally, health practitioners may give lower-quality diagnoses, medication and care and may even show neglect towards those discriminated against. Indirect discrimination that indigenous peoples experience may on the surface appear neutral, but it has the effect of discrimination. One prime example of indirect discrimination includes providing health information and services only in the dominant language or in accordance with dominant cultural practices, which results in the de facto exclusion of indigenous peoples. In the Asian region, as in other parts of the world, indigenous peoples have spoken clearly on this issue stating that such a data revolution should include the collecting disaggregated information on key indicators for both baseline and progress tracking.
