For female household members, HWFWTHTPCTRMDHS (HA12) reports the woman's weight-for-height as a percent of the median weight for a reference population of the same height. For this variable, the reference population was developed by the DHS Program. This index has been adjusted for pregnant women according to duration of pregnancy.
The following variables report the woman's weight for height as a percent of the median weight for different reference populations:
HWFWTHTPCTRMFOG (HA12A) uses Metropolitan Life or Fogarty reference standards
HWFWTHTPCTRMWHO (HA12B) uses WHO reference standards
