Data from the World Health Organization (WHO) Model Disability Survey reveal that environmental factors such as inaccessible physical environments and transportation, lack of social support and assistive devices, and negative attitudes and barriers for accessing health care, increase limitations in functioning for persons with disabilities to a higher extent than people without disabilities., 
Providing cross-sectoral public health interventions that address the social determinants and risk factors to inclusive and equitable health, accelerates the achievement of the health sector in improving the health and well-being of its populations. Furthermore, advancing health equity for persons with disabilities is central to all efforts in protecting populations in health emergencies.
Health equity contributes to a meaningful participation in society
Advancing health equity is a prerequisite for the wider participation into society of persons with disability. Good health and well-being are essential to living a decent and meaningful life. Not benefiting from necessary health care hinders the realization of other fundamental rights, such as the right to education or employment. By not receiving the required health services, such as rehabilitation and assistive technology, persons with disability may not be able to go to work, attend school, access livelihood opportunities, or participate in community life and society.
