Do women know that prenatal testing detects fetuses with Down syndrome?

Area of Science:

• Maternal Health
• Reproductive Genetics
• Public Health Communication

Background:

• Prenatal testing offers valuable insights into fetal health during pregnancy.
• Understanding women's expectations of prenatal testing is key to effective genetic counseling.
• Advanced maternal age (37 years and over) is associated with increased risks for certain chromosomal abnormalities.

Purpose of the Study:

• To investigate the expectations of pregnant women aged 37 and over regarding prenatal testing.
• To identify which conditions, specifically Down syndrome, pregnant women associate with prenatal screening and diagnosis.
• To assess the clarity of information provided about prenatal testing outcomes.

Main Methods:

• A questionnaire-based study was conducted in Victoria, Australia.
• 432 pregnant women aged 37 years and over participated.
• Content analysis was used to examine responses about expected prenatal test information.

Main Results:

• 61.3% of participants mentioned Down syndrome, chromosomal abnormalities, or trisomies.
• Women undergoing both screening and diagnosis were more likely to mention Down syndrome (adjusted OR = 1.6).
• Women from English-speaking backgrounds were significantly more likely to mention Down syndrome (adjusted OR = 3.5).

Conclusions:

• A significant proportion of pregnant women (nearly 40%) did not mention Down syndrome when asked about prenatal testing expectations.
• There is a need for improved patient education regarding the scope and potential findings of prenatal diagnostic and screening tests.
• Clearer communication is essential to ensure pregnant women are fully informed about detectable conditions like Down syndrome.
