Summary

Drink size significantly impacts estimated alcohol consumption in pregnant women at risk for Fetal Alcohol Syndrome. Standard drink sizes underestimate actual intake, potentially masking high-risk drinking behaviors.

Area of Science:

  • Public Health
  • Maternal Health
  • Alcohol Consumption Research

Background:

  • Fetal Alcohol Syndrome (FAS) is a significant concern during pregnancy.
  • Accurate assessment of alcohol consumption is crucial for identifying at-risk pregnancies.
  • Standard drink size definitions may not reflect actual consumption volumes.

Purpose of the Study:

  • To investigate the role of self-defined drink size in determining average daily alcohol consumption.
  • To assess consumption patterns among women at risk for Fetal Alcohol Syndrome.

Main Methods:

  • Cross-sectional retrospective interviews with 321 pregnant women from diverse ethnic backgrounds in urban California.
  • Utilized graduated frequency series and respondent-defined vessel sizes to calculate alcohol volume.

  • Community outreach supplemented clinic-based recruitment.

    • Main Results:

    • Self-selected drink sizes were significantly larger than standard sizes, ranging from 49% (beer) to 307% (spirits) greater.
    • Average daily consumption for at-risk women increased substantially when self-defined sizes were used.
    • Daily ethanol intake for high-consumption women rose from 57g to 153g when accounting for larger drink sizes.

    Conclusions:

    • Current risk assessments may underestimate alcohol consumption due to standard drink size assumptions.
    • Screening protocols for at-risk drinkers should include questions about actual drink sizes.
    • Higher true risk levels for FAS may exist than previously recognized.
