To map and synthesise existing evidence on pregnant women’s perceptions and experiences of social media communication for antenatal care (ANC).

Scoping review.

Four electronic databases (PubMed/MEDLINE, Embase, Web of Science and Google Scholar) alongside ‘grey’ and supplementary searches were conducted between December 202–January 2026.

All studies reporting pregnant women’s perceptions or experiences of social media communication for ANC.

Data were extracted independently by two reviewers using a structured charting framework. Extracted data were synthesised using a descriptive and narrative approach, with pregnant women’s perceptions and experiences analysed through reflexive thematic analysis.

Six studies met the inclusion criteria. Across platforms including WhatsApp, Facebook, Instagram and WeChat, pregnant women generally perceived social media communication as acceptable and beneficial, particularly for accessing trustworthy information, reassurance between visits, peer support and flexible engagement. Experiences varied by platform, moderation model and context. Key challenges included limited personalisation, variability in moderators’ capacity and responsiveness, digital literacy barriers, data affordability, privacy concerns and sociocultural influences. Equity-related considerations were recurrent, highlighting the potential for uneven experiences if digital communication is not carefully designed and standardised.

Social media communication is generally experienced positively by pregnant women as a complement to routine ANC, particularly when professionally moderated and responsive to women’s informational needs. However, variability in experiences and equity-related challenges underscore the need for further research and careful implementation. This scoping review provides a preliminary mapping of the evidence and identifies priorities for future qualitative synthesis, primary research and the development of inclusive, person-centred digital ANC communication strategies.

To compare birth weight-to-placental weight (BW:PW) ratios between pregnancies complicated by gestational diabetes mellitus (GDM) and normoglycaemic pregnancies, and to evaluate the associations between BW:PW ratio, perinatal outcomes, and placental histopathologic features within the GDM group.

A prospective cohort study.

A university hospital in Bangkok, Thailand.

A total of 200 women with GDM and 100 normoglycaemic controls.

BW:PW ratios were calculated and compared between the two groups. Participants with GDM were stratified into three categories based on the BW:PW ratio percentiles: 90th. Perinatal outcomes and placental histological abnormalities were analysed across these categories.

Median BW:PW ratios were not significantly different between the GDM and normoglycaemic groups: 6.3 (IQR 5.6 to 6.9) versus 6.2 (IQR 5.6 to 6.8); p=0.399. Within the GDM cohort, the BW:PW ratio cut-offs corresponding to the 10th and 90th percentiles were 5.2 and 7.6, respectively. The prevalence of small-for-gestational-age (SGA) neonates differed significantly among the three BW:PW ratio groups: 14.3% (90th); p=0.004. Similarly, the prevalence of chorangiosis varied significantly across these groups (66.7%, 52.9% and 22.7%, respectively; p=0.009). A BW:PW ratio 90th percentile was associated with reduced odds of chorangiosis (aOR 0.35; 95% CI 0.11 to 0.85).

BW:PW ratios did not differ significantly between the GDM and normoglycaemic groups. However, in GDM pregnancies, extremes in the BW:PW ratio were associated with distinct perinatal and placental outcomes, indicating altered placental efficiency and potential clinical relevance.
