Current attitudes and preconceptions on newborn genetic screening in the Chinese reproductive-aged population.

PURPOSE: Newborn screening (NBS) applications are limited as they can only cover a few genetic diseases and may have false positive or false negative rates. A new detection program called newborn genetic screening (NBGS) has been designed to address the potential defects of NBS. This study aimed to investigate the perceptions, acceptance, and expectations of childbearing people related to NBGS to provide the basis for the targeted improvement in the NBGS program carried out in Hospitals.

METHODS: A questionnaire with 20 items was designed on www.wjx.cn . Individuals who came to the Nanjing maternity and child health care Hospital for consultation from June 2021 to August 2021 participated in the survey. The data of the study was arranged properly and analyzed after the investigation.

RESULTS: A total of 1141 valid questionnaires were collected in the survey, in which the average age of the participants was 31 (± 4) years, and a 1:4 ratio of males to females. Additionally, 65.12% of the participants possessed a bachelor's degree or above qualification. Overall, 50.57% of participants had an annual household income of 100,000-250,000 RMB, while about 86.68% of the participants supported the development of NBGS. The participation cost to pay for NBGS depended on the family incomes; about 59.42% of them were willing to pay a participation fee of 1000-2000 RMB.

CONCLUSION: Our research provisionally demonstrated that the residents generally supported the use of NBGS, especially those with higher educational degrees, but the understanding of the genetic diseases and NBGS among the low-educated population still needs to be strengthened.
