Anxiety and depression are prevalent during pregnancy. There is significant evidence that antenatal anxiety and depression are risk factors for adverse maternal and neonatal outcomes.

This study aims to determine the prevalence of anxiety and depression among pregnant women who undergo ultrasonographic detection of structural fetal anomalies in the Department of Maternal and Fetal Medicine of University of the Philippines–Philippine General Hospital, Manila, Philippines, for a 13-month period.

The study utilized a comparative cross-sectional study design comparing those who underwent congenital anomaly scan (CAS) with those who just underwent routine biometry. There were 177 research respondents for each group. The Filipino version of the Hospital Anxiety and Depression Scale (HADS-P) was used. The psychiatric interview was based on the 5th edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM V) particularly on the Major Depressive DIsorder and the Generalized Anxiety Disorder.

The results showed that the mean pre-diagnostics anxiety score of women who underwent CAS was significantly higher than the mean pre-diagnostics anxiety score of women who had biometry. The mean post-diagnostics depression score of women who underwent CAS was significantly higher than the mean post-diagnostics depression score of women who had biometry. However, all pregnant women had normal HADS-P score before and after CAS and biometry. Psychiatric evaluation showed that none was diagnosed to have generalized anxiety disorder or major depression in the conduct of the diagnostic tests.

This study indicates that generalized anxiety and depression among pregnant patients subjected to routine biometry and congenital scan were not problems in this tertiary hospital. Knowledge of CAS and awareness of risk factors for congenital anomalies are important for providing care and counseling pregnant women.
