This article reports on the accessibility of online public health campaigns such as Australian cancer screening programs for people with intellectual disability. A range of accessibility issues were found, demonstrating that government public health initiatives need to make improvements to ensure they meet the communication and information rights of people with intellectual disability and reduce the risk of under-screening among this population.

The study evaluated Australian government health websites promoting the national breast, bowel, and cervical screening programs for their compliance with accessibility guidelines. The accessibility errors identified included low-contrast colors, missing alternative text, broken links, and excessive content. Readability was a consistent issue, with most materials written at levels considered too high for both people with intellectual disability and the general population. 

The creation and dissemination of more accessible materials should be a priority for governments and health services to meet the communication needs of people with intellectual disability and uphold their right to information about their healthcare.
