*Data in this table are constructed from survey questions 4 and 5. (BMI is a relationship between weight and height that is associated with body fat and health risk.)

~Low participation was a substantial problem for NC PRAMS in 2011.The overall weighted response rate was 54%.

*** This estimate was suppressed because it did not meet statistical reliability standards

#Use caution in interpreting cell sizes less than 50.
N = Cell Size, % = Percentage, C.I.(95%) = Confidence Interval (at 95 percent probability level).
The percentages shown are weighted percentages, designed to reflect the entire population of North Carolina women having a live birth.
