Maternal eating disorders and disordered eating behaviors increase the risk of delivering small-for-gestational-age (SGA) infants. Low pre-pregnancy weight and poor weight gain are key predictors for SGA infants, highlighting the impact of maternal factors on infant growth.

Area of Science:

  • Reproductive Health
  • Maternal-Fetal Medicine
  • Psychiatry

Background:

  • Low birth weight (LBW) is a significant global health concern.
  • Maternal factors, including eating disorders and body image concerns, may influence infant birth weight.
  • Understanding these associations is crucial for targeted interventions.

Purpose of the Study:

  • To investigate the link between clinical eating disorders, maternal weight/shape concerns, and LBW infants.
  • To identify predictors for delivering small-for-gestational-age (SGA) and premature (PREM) LBW infants.

Main Methods:

  • Retrospective case-control study involving 88 women with LBW infants and 86 controls.
  • Interviews included a modified Eating Disorder Examination (EDE) to assess eating disorder history and concerns.

  • Participants were categorized into term SGA, premature (PREM), and control (CTRL) groups.

    • Main Results:

    • 32% of SGA women had a clinical eating disorder before pregnancy, compared to 9% of PREM and 5% of CTRL women.
    • Women delivering SGA infants showed elevated postpartum eating disorder psychopathology and pre-pregnancy/pregnancy eating disturbances.
    • Predictors for LBW term SGA infants included low pre-pregnancy weight, smoking, low weight gain, and bulimia symptoms.

    Conclusions:

    • Disordered eating significantly increases the risk of delivering term SGA infants.
    • Maternal behaviors and pre-pregnancy characteristics are critical predictors of term growth retardation.
    • Early identification and management of eating disorders in pregnant women may improve infant outcomes.
