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 female household members, HWFWTHTSDRM (HA11) reports the difference between the woman's weight and the median weight of a reference population of the same height and sex, expressed in units equal to one standard deviation of the reference population's distribution. This variable uses a DHS reference standard.
An anthropometry measure expressed in reference standard deviation units is also known as a Z-score. HWFWTHTSDRM values are reported in units equal to 100 times the Z-score, to preserve two decimal places without requiring the use of a decimal point. Dividing HWFWTHTSDRM by 100 will yield the weight-for-height Z-score (WHZ) value.
The complementary DHS variable HWFWTHTPCTRMDHS (HA12) reports weight-for-height percentiles within the same reference population. Unlike z-scores, percentiles do not allow comparison across age and sex and cannot assess longitudinal change in growth status; users are advised to consult anthropometry literature for further discussion.
