For household members under age 5, HWCWTAPCTRM (HC9) reports their weight-for-age as a percent of the median weight for a reference population of the same age and sex. For this variable, the reference population was developed by the U.S. Centers for Disease Control. Low weight-for-age, or "underweight," is an indicator of acute and/or chronic malnutrition,
HWCWEIGHT (HC2) reports the young household member's weight as measured by DHS personnel. The related variable AGEMOHHLT5 (HC1) reports age in months at the time of measurement.
The similar variable HWCWTAPCT (HC7) reports the young household member's weight-for-age percentile relative to smoothed percentile growth charts by age and sex, for the same reference population.
For an alternative measure of stunting in terms of weight-for-age and using the same reference population, see HWCWAZNCHS (HC8). HWCWAZNCHS reports the difference between the height and the median weight of the CDC reference population of the same age and sex, expressed in units equal to one standard deviation of the reference population's distribution.
