Description

Definition
BIOFWTHTSDRM (V444A) reports the difference between the respondent'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. BIOFWTHTSDRM 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 BIOFWTHTSDRM by 100 will yield the height-for-age Z-score (HAZ) value.

The complementary DHS variable BIOFWTHTPCTDHS (V442) 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.
