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.
