Overview

Systematic review reveals mixed effectiveness of dietary interventions in pregnant women, highlighting the role of behavior change techniques.

Key Points

  • Current dietary interventions primarily focus on enhancing psychological capability in pregnant women.
  • Common behavior change techniques include goal setting and knowledge shaping, but social factors are less addressed.
  • Forty-five studies were included, revealing substantial heterogeneity in intervention designs and outcomes.
  • Future interventions should consider broader COM-B dimensions and address health literacy disparities for better outcomes.
