BACKGROUND: Postpartum depression (PPD) remains a major public health concern. In China, the postpartum period is embedded within a family-based caregiving system characterized by intensive intergenerational involvement. Within this context, intergenerational support (IS) and intergenerational conflict (IC) often coexist, forming a distinct stress-regulation environment. Guided by the stress-buffering model of social support, this study conceptualizes the Chinese postpartum family as a dynamic system in which IS and IC jointly shape maternal mental health over time.
METHODS: A four-wave longitudinal design was employed. Parallel Process Latent Growth Curve Modeling (PP-LGCM) was used to examine the co-developmental trajectories of IS, IC, and PPD symptoms. Logistic regression analyses were conducted to identify multilevel predictors of trajectory subgroups.
RESULTS: The prevalence of elevated depressive symptoms (EPDS ≥ 9) ranged from 23.1% to 24.2% across assessments, while probable PPD (EPDS ≥ 13) ranged from 4.6% to 7.2%. PP-LGCM identified five distinct joint trajectory classes: Moderate-risk group (n = 30; 8.6%), Mild-risk group (n = 103; 29.7%), Improving group (n = 45; 13.0%), Resistant group (n = 139; 40.1%), and High-risk group (n = 30; 8.6%). Trajectory membership was significantly associated with living arrangement, sleep quality, psychological flexibility, and partner relationship.
CONCLUSIONS: In the urban Chinese postpartum context, PPD symptom trajectories are closely linked to intergenerational family dynamics. These findings underscore the need for family-based prevention and treatment that, when feasible, engages parents/parents-in-law (and partners) to align caregiving expectations and roles, particularly for women in high-risk or worsening trajectory subgroups.
