Abstract

BACKGROUND: Perinatal depression affects 21-50% of women in South Africa and poses significant health risks to mothers and children. Trajectories of depressive symptoms change over time and have not been well characterized during the perinatal period in low and middle-income countries. METHODS: Data from women enrolled in a population-based birth cohort study in Paarl, South Africa with at least 3 depression measures from pregnancy through 18 months postpartum (N = 831) were analyzed. Depressive symptoms were measured continuously using the Edinburgh Postnatal Depression Scale (EPDS). Group-based trajectory models were used to estimate trajectories of depressive symptoms during the perinatal period and multinomial multivariable models to identify predictors of trajectory group membership. RESULTS: Five distinct trajectory patterns of depressive symptoms were identified: moderate levels of depressive symptoms during pregnancy but minimal postpartum (3.5%), minimal levels during pregnancy and increasing postpartum (3.7%), unstable levels peaking at 12 months postpartum (6.6%), mild levels with slight decrease postpartum (82.9%), and severe levels during pregnancy and postpartum (3.1%). Membership in the chronic severe symptom group was associated with stressful life events, sexual intimate partner violence and tobacco use. LIMITATIONS: Modeling limitations prevented determining how changes in psychosocial predictors over time may influence depressive symptom trajectories. CONCLUSIONS: Mild to severe depressive symptoms during pregnancy/postpartum were common among this South African cohort. Interventions to treat women with severe chronic depressive symptoms with co-occurring psychosocial issues are urgently needed.

  • The findings highlight the influential role of poverty-related risk factors, including unemployment, deprivation, disempowerment, and food insecurity, in shaping maternal mental health and subjectivities.

    “The findings highlight the influential role of poverty-related risk factors, including unemployment, deprivation, disempowerment, and food insecurity, in shaping maternal mental health and subjectivities (22, 65).”

    From “Motherhood is a work in progress”: a qualitative longitudinal study of maternal subjectivity and well-being of women in the Bukhali trial in Soweto, South Africa (2026) · cites this paper as [22]

    The Introduction (page unavailable) identifies unemployment and food insecurity as social factors that may exacerbate depressive symptoms, supporting part of the claim as background context. But the Discussion (page unavailable) says unemployment was not significantly associated with the depression trajectory tested; the paper does not establish effects of deprivation or disempowerment, or address maternal subjectivities. The claim overstates these factors as findings of this study. (LLM, conf=0.86)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
