The sample sizes used in this study varied from indicator to
indicator. We used the total sample for AAM and INC. For
AANC and DHF, we used the sub-sample who gave birth
during a defined period preceding the survey (three years for
the survey of 1993-94 and five years for the others). No data
was available in the BDHS 1993-94 for the underweight and
overweight indicators. All indicators were dichotomised except
being underweight and overweight.
