Postpartum depression (PPD) affects up to one in five new mothers, posing significant challenges for maternal and infant well-being. With social media becoming a popular source of social connection and information for postpartum women, understanding how digital engagement influences mental health is increasingly important. This literature review synthesizes evidence on how patterns of social media use, such as time spent, platform type, and content interaction, relates to depressive symptoms in postpartum women.

A structured literature search was conducted using the Elicit semantic engine which searched for academic papers from Semantic Scholar and OpenAlex. The query, “How do patterns of social media use (e.g., time spent, type of content) relate to depressive symptoms in postpartum women?” yielded 50 relevant papers. Screening criteria included postpartum population (≤12 months postpartum), assessment of social media use, validated depression measurement, quantitative data, and examination of social media–depression relationships. Four studies met inclusion criteria, encompassing diverse methodologies: one longitudinal cohort (Zhang et al., 2020), two cross-sectional studies (Kıyak & Batı, 2024; Kinser et al., 2021), and one randomized controlled trial (Guevara et al., 2023).

Three studies reported positive associations between specific social media behaviors and higher depressive symptoms. Frequent selfie posting on WeChat Moments was linked to a 2.27-fold increase in PPD risk (95% CI, 1.33–3.87; p = .003). Greater emotional connection and social integration on Instagram predicted higher depression scores (OR = 0.928 per unit increase; p = .010). Increased general media consumption during the COVID-19 pandemic correlated with greater anxiety and implied depressive outcomes. Conversely, one randomized controlled trial demonstrated that participation in a Facebook-based parenting program reduced depressive symptoms, with an adjusted Edinburgh Postnatal Depression Scale (EPDS) score decrease of 2.9 points (95% CI, –4.8 to –1.0; p < .05). Moderators such as younger maternal age, perfectionism, socioeconomic stressors, and cultural context influenced the direction and strength of these associations. Notably, structured, supportive engagement (e.g., educational or parenting programs) appeared protective, whereas comparison-driven or emotionally intensive use heightened risk.

Evidence indicates that the relationship between social media use and postpartum depression is multifaceted and context-dependent. While unstructured or comparison-oriented social media engagement may exacerbate depressive risk, structured and community-based interventions can promote positive mental health outcomes. These findings highlight the dual role of social media as both a risk and a resource in postpartum adjustment. This investigation has also highlighted the minimal research available in this area, and the need for further investigation.

Future research should employ longitudinal and experimental designs to clarify causal pathways and identify strategies for leveraging digital platforms to support maternal well-being.
