Pregnancy Anti-inflammatory Diet Intervention Study

Dietary patterns may influence maternal inflammatory status and pregnancy outcomes. However, structured anti-inflammatory dietary interventions specifically designed for pregnant women remain limited. This study aims to develop and evaluate an evidence-based, theory-informed anti-inflammatory dietary intervention to improve dietary habits and reduce dietary inflammatory potential during pregnancy. The intervention will be developed through evidence synthesis, qualitative research, and expert consultation, guided by the the Behaviour Change Wheel. Following intervention development, a randomized controlled trial will be conducted to assess its feasibility, acceptability, and preliminary effects. Pregnant women will be randomly assigned to an intervention group receiving individualized anti-inflammatory dietary guidance and behavioral support or a control group receiving routine antenatal care. Outcomes will include intervention feasibility, dietary inflammatory potential, maternal inflammatory biomarkers, and relevant pregnancy-related outcomes. The findings will inform further refinement of the intervention and provide evidence for future research.
