Summary

Maternal weight gain during pregnancy impacts infant and mother health. Following Institute of Medicine (IOM) guidelines is linked to optimal outcomes, though most women don't meet these recommendations.

Area of Science:

  • Obstetrics and Gynecology
  • Maternal-Fetal Medicine
  • Public Health Nutrition

Background:

  • Maternal weight gain recommendations in pregnancy have historically varied.
  • The 1990 Institute of Medicine (IOM) guidelines aimed to improve infant birth weight but faced criticism regarding perinatal outcomes.
  • Controversy exists regarding the optimal approach to maternal weight gain for fetal and maternal well-being.

Purpose of the Study:

  • To systematically review existing studies on fetal and maternal outcomes in relation to IOM weight-gain recommendations for women with normal prepregnancy weight.
  • To assess the association between adherence to IOM weight-gain ranges and health outcomes.
  • To identify the need for further research, particularly experimental studies, on optimizing maternal weight gain.

Main Methods:

Related Experiment Videos

  • Systematic review of observational studies.
  • Analysis of fetal and maternal outcomes based on adherence to IOM pregnancy weight-gain recommendations.
  • Focus on women with a normal prepregnancy body mass index.

Main Results:

  • Pregnancy weight gain within the IOM's recommended ranges is associated with the most favorable outcomes for both mothers and infants.
  • A significant proportion of pregnant women do not achieve weight gain within the recommended IOM ranges.
  • Current evidence is primarily from observational studies.

Conclusions:

  • Adherence to Institute of Medicine (IOM) weight-gain guidelines during pregnancy is linked to optimal maternal and infant health outcomes.
  • Most pregnant women do not meet the recommended weight-gain targets.
  • Further experimental research is crucial to develop interventions for improving maternal weight gain and optimizing health outcomes.
