Abstract
AIMS: To investigate clinically relevant subtypes of perinatal depressive symptoms. DESIGN: Cross-sectional study. METHODS: A sample of 2,783 women at different prenatal and postnatal periods was recruited between August 2015 - August 2017. The Patient Health Questionnaire-9 (PHQ-9) was used to assess depressive symptoms. Data analyses consisted of latent class analysis (LCA), analysis of variance and multinomial logistic regression. RESULTS: (a) Five latent subtypes (Classes 5/4/3/1/2) were identified: 'no symptoms', 'mild physio-somatic symptoms', 'severe physio-somatic symptoms and moderate anhedonia', 'moderate-to-severe symptoms' and 'severe symptoms'; (b) Postpartum women were more likely to belong to the severe depressive symptoms group, whereas pregnant women were likely to report severe physio-somatic symptoms; and (c) History of abortion and perinatal complications increased the likelihood of belonging to all moderate-to-severe classes. Lower levels of education increased the probability of belonging to Class 2. Younger women were more likely to be categorized into Classes 1 and 2. CONCLUSIONS: This is the first study to examine heterogeneity of perinatal depressive symptoms and delineate the characteristics of subtypes at different prenatal and postnatal periods via the PHQ-9, using LCA in a Chinese general population. IMPACT: This research details the heterogeneity of perinatal depressive symptoms and delineates the characteristics of subtypes at different prenatal and postnatal periods in a Chinese general population.
