Objective: Data on psychiatric morbidity in high-risk pregnant Singaporean women are limited. This study aimed to establish the prevalence of antenatal depression and anxiety in high-risk pregnancies, compare the prevalence of antenatal depression in high-risk pregnancies vs. pregnancies of unspecified obstetric risk and examine the Edinburgh Postnatal Depression Scale (EPDS) and State Trait Anxiety Inventory (STAI) as screening tools for these disorders.
Method: Two hundred high-risk pregnant inpatients at a national public maternity hospital were included. Three psychometric assessment tools were used to evaluate all participants: the diagnostic Mini International Neuropsychiatric Interview and the screening EPDS and STAI.
Results: Rates of major depression, minor depression, anxiety disorder (agoraphobia, generalized anxiety disorder, panic disorder), and comorbid depression and anxiety were 11%, 7%, 12.5% and 5%, respectively. Major depression was more prevalent in high-risk pregnancies than in the historical cohort of unspecified obstetric risk (11% versus 4.3%). EPDS (cutoff 8/9) screens well for depression and anxiety in high-risk pregnancies (area under the receiver operating characteristic curve=0.82-0.87).
Conclusion: Antenatal depression and anxiety are highly prevalent in a sample of high-risk pregnant Singaporean women. EPDS performs well in screening for depression and anxiety in high-risk pregnant women, with further psychiatric assessment recommended for women with score ≥ 9.
