To understand the level of postpartum depression literacy among women in Guiyang within 0-6 months postpartum, and to analyze the latent profile categories of postpartum depression literacy, in order to effectively carry out mental health services.

The communities were selected through multi-stage stratified random sampling, and 1 088 subjects were continuously included in the study. A questionnaire survey was conducted using general information, the Edinburgh Postnatal Depression Scale (EPDS), and the Postpartum Depression Literacy Scale (PoDLis). A latent profile analysis was performed on postpartum depression literacy, and logistic regression was used to analyze the influencing factors.

The positive rate of postpartum depression symptoms was 14.5%. The total score of postpartum depression literacy was 3.29 (3.00, 3.58) points. The postpartum depression literacy of the mothers was divided into three latent classes: the low literacy group (5.97%), the medium literacy group (47.88%), and the high literacy group (46.14%). Younger maternal age (OR=3.282, 95% CI: 1.130-9.534), high school education (OR=2.296, 95% CI: 1.080-4.880), and low monthly per capita family income (OR=2.385, 95% CI: 1.050-5.420) were risk factors for the low literacy group, while participating in relevant courses (OR=0.673, 95% CI: 0.472-0.959) was a protective factor for the high literacy group (P<0.05).

There is heterogeneity in postpartum depression literacy among women. Special attention should be paid to women with younger maternal age, low educational level, low family economic level, and no participation in maternity school courses. Interventions can be implemented based on the characteristics and influencing factors of different latent classes to improve postpartum depression literacy and prevent the occurrence of postpartum depression.
