Point estimateAnalysis weights
• Each respondent “speaks” for about 12 other women
Not selected for sample or who
did not respond• Weighting process complex
•Done by CDC PRAMS•See PRAMS reports on DOH website
![Page 26: Maternal & Child Health Epidemiology: An Overview of Selected Data Systems Data Users Conference November 17, 2004 Presented by Susan Nalder, EdD, MPH,](https://reader030.vdocument.in/reader030/viewer/2022032723/56649d1f5503460f949f25d7/html5/thumbnails/26.jpg)
Potential bias from
• Less than 100% response – about 30% do not participate
• Mail survey: appeals to more educated women, but many less-advantaged women participate
• Phone respondents vs. mail• Recall (2-6 months after birth)• Self-report by respondent
