Objective: To compare stress, anxiety and depression levels among 3 groups of pregnant women: 1) low-risk outpatient (LRO), 2) high-risk outpatient (HRO), and 3) inpatient (IP).
Methods: This was a cross-sectional study using validated instruments. Inclusion criteria were pregnancies 23-37 weeks and maternal age > 18 years. The primary outcome was mean/median scores of Perceived Stress Scale (PSS), State Trait Anxiety Inventory (STAI), and Edinburgh Depression Scale (EDS). Secondary outcome was rate of abnormal scores.
Results: Among 190 women approached, 180 (95%) participated, with 60 (33%) in each group. Mean PSS scores (range 0-40) significantly increased from LRO (12.0, standard deviation [SD] 7.8) to HRO (14.7, SD 7.9) to IP (15.6, SD 8.2); p = .04. Mean STAI scores (range 20-80) also significantly increased from LRO (32.0, SD 11.1) to HRO (35.8, SD 11.9) to IP (40.9, SD 13.1); p < .01. Abnormal anxiety (STAI ≥ 40) was present in 40% of women and significantly higher among IP compared to LRO (56% vs 25%; RR 2.24, 95% CI 1.36-3.67; aRR 2.24, 95% CI 1.34-3.74).
Conclusion: Stress and anxiety scores significantly differ in LRO, HRO, and IP women. While depression screening is common postpartum, screening for stress, anxiety and depression prenatally may be beneficial.
