    Obstetrical risk scores effectively identify pregnant women at higher risk for low birth weight (LBW) infants. However, nutritional risk screening based on food frequency did not predict LBW incidence in this study.

    Area of Science:

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

    Background:

    • Identifying high-risk pregnancies is crucial for improving maternal and infant outcomes.
    • Existing screening tools may not fully capture all risk factors for adverse pregnancy outcomes.
    • Nutritional status is a key determinant of fetal growth and birth weight.

    Purpose of the Study:

    • To develop and implement obstetrical and nutritional risk screening systems for pregnant women.
    • To evaluate the predictive value of these screening systems for identifying women at risk of delivering low birth weight (LBW) infants.

    Main Methods:

    • Development of an obstetrical risk score incorporating maternal age, parity, interconceptional period, pre-gravid weight-for-height, and history of miscarriages or LBW infants.

  • Implementation of a nutritional risk screening system using a modified food frequency questionnaire assessing intake from four major food groups.
  • Analysis of data from 910 WIC and 418 non-WIC pregnant women to assess the association between risk scores and LBW incidence.

    • Main Results:

    • Women classified as high risk by the obstetrical score demonstrated a significantly higher incidence of LBW infants compared to low-risk women.
    • The nutritional risk screening score did not show predictive value for identifying women likely to deliver LBW infants.
    • The study population included both WIC and non-WIC participants, providing a diverse sample.

    Conclusions:

    • The developed obstetrical risk score is a valuable tool for identifying pregnant women at increased risk for LBW infants.
    • Nutritional risk assessment using the described food frequency method was not effective in predicting LBW in this cohort.
    • Further research may be needed to refine nutritional screening tools for predicting adverse birth outcomes.
