Socioeconomic status and uptake of reproductive carrier screening in Australia

Abstract

Reproductive carrier screening enables the early identification of genetic conditions that may impact the long-term health of a child, including cystic fibrosis, fragile X syndrome, and spinal muscular atrophy. We used unique data from the major providers of pathology services in Australia to profile women who intend on becoming, or who are, pregnant and access basic to advanced testing for genetic conditions. We found a strong socioeconomic gradient in the uptake of reproductive carrier screening, with women living in the most advantaged postcodes across Australia significantly being more likely to have reproductive carrier screening than those living in the most disadvantaged areas. These results highlight the need to minimise social and financial barriers that are currently limiting access.
