For instance, in some populations where perceptions of race are linked with socioeconomic disparities and differences, the access to care can be considerably lesser.[11] Dually, bias in healthcare systems themselves can perpetuate non-biologically founded higher instances of disease. A study conducted by the National Health Service checks program in the United Kingdom, which aims to increase diagnosis across demographics, noted that "the reported lower screening in specific black and minority ethnic communities... may increase inequalities in health."[12] In this specific case, the lack of attention to certain demographics can be seen as a cause of increased instances of disease from this lack of proper, equal preventative care. One must consider these external factors when evaluating statistics on the prevalence of disease in populations, even though genetic components can play a role in predispositions to contracting some illnesses.
