Warning: these figures indicate the number of cases found in the data file. They cannot be interpreted as summary statistics of the population of interest.
For women who gave birth in the 3 years before the survey's calendar period, PRECBRFEDUR (V427) reports the duration in months of breastfeeding for the last child born in the 3 years preceding the start of the calendar. The survey's calendar period is typically 5 years, meaning PRECBRFEDUR usually refers to births between 6 and 8 years before the survey.
The maximum period of breastfeeding allowed during the creation of PRECBRFEDUR was the interval between the date of birth of the child and the date of the interview. Cases exceeding this duration were left with the original response but are coded with a flag in PRECBRFDFLAG (V429), and were set to "Inconsistent" (code "97") in PRECBRFDMO (V428).
