Objective: Second-trimester anomaly scan was introduced as a regulated practice in Romania in 2019, causing misperceptions and unrealistic expectations about this examination among pregnant women. This study aimed to assess whether second trimester anomaly scan is a reason "per se" for maternal anxiety.
Design: A prospective type 1 cohort study was conducted in a tertiary prenatal diagnosis center with three locations in Bucharest, Romania, among pregnant women who underwent a second trimester anomaly scan between 1 December 2019 and 29 February 2020.
Main outcome measure: Anxiety at the time of prenatal anomaly scan.
Results: Out of the 138 participants, 32.6% believed that the anomaly scan could detect all fetus defects, 13.8% considered that the baby is bothered by the probe "light", 8.7% believed that the scan could harm the fetus, 96.4% reported that it was a pleasant experience, and 95% felt that it strengthened their bond with the fetus. The State-Trait Anxiety Inventory (STAI) score revealed that women with high state anxiety were more anxious at pre-scan (p = 0.001).
Conclusion: Ultrasound scan in the second trimester is correlated with a significant anxiety for women who are prone to this psychological trait. It is also a good opportunity to screen for highly anxious women who could benefit from prenatal psychological counseling to facilitate timely recognition and prevention of postpartum psychiatric disorders such as depression.
