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, PRECBRFDUR (V429) is a flag variable that indicates the type of problem, if any, found in editing responses on the duration of breastfeeding. The survey's calendar period is typically 5 years, meaning PRECBRFDUR usually refers to births between 6 and 8 years before the survey. Cases without a problem are coded to 0.
For duration of breastfeeding, see PRECBRFDUR (V427).
