Drwy ein gwaith gyda Sefydliad Iechyd y Byd, nodwyd y pum cyflwr hanfodol sydd eu hangen i sicrhau tegwch iechyd, gan gynnwys y system iechyd a gofal; diogelwch incwm a gwarchodaeth gymdeithasol; amodau byw; cyfalaf cymdeithasol a dynol; ac amodau cyflogaeth a gwaith. Mae'n taflu goleuni ar y bylchau sylweddol mewn iechyd a hunanadroddir rhwng y rhai sydd â sicrwydd ariannol a'r rhai sydd heb.
Our work with the WHO highlighted the five essential conditions needed to ensure health equity, including the health and care system; income security and social protection; living conditions; social and human capital; and employment and working conditions.  It shines a light on the significant gaps in self-reported health between those who are financially secure and those who are not.
