Nutritional advice can increase pregnant women's energy and protein intake. However, the study found limited evidence on its impact on pregnancy outcomes, suggesting it may not be a major intervention.

Area of Science:

  • Maternal and Fetal Health
  • Nutritional Science
  • Evidence-Based Medicine

Background:

  • Nutritional intake during pregnancy is crucial for maternal and fetal well-being.
  • Previous research explored protein and energy supplementation, but the impact of nutritional advice alone is less clear.

Purpose of the Study:

  • To evaluate the effectiveness of advising pregnant women to increase energy and protein intake.
  • To assess the impact of this advice on maternal nutritional status, gestational weight gain, and pregnancy outcomes.

Main Methods:

  • Systematic review of controlled clinical trials from the Cochrane Pregnancy and Childbirth Group register.
  • Inclusion of trials involving one-to-one or group nutritional advice on energy and protein intake.
  • Data extraction from published reports and direct contact with trialists.

Main Results:

  • Nutritional advice was successful in increasing energy and protein intake, though to a lesser extent than direct supplementation.
  • Limited data on pregnancy outcomes from one trial, with potential statistical limitations.
  • No consistent evidence of reduced preterm birth or pre-eclampsia; no data on adverse effects of increased fetal size.

Conclusions:

  • Nutritional advice effectively increases pregnant women's energy and protein intake.
  • The available trial data are insufficient to determine implications for fetal, infant, or maternal health.
  • Given modest benefits of supplementation, advice alone is unlikely to be a major intervention.
