*Data in this table are constructed from survey questions 1 and 2. (BMI is a relationship between weight and height that is associated with body fat and health risk.)

The overall weighted response rate in 2015 was 51%. It fell short of the 55% rate that PRAMS has regarded as the epidemiologically valid threshold.

*** 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.
