Description

Definition

For female household members of childbearing age, HWFHEMOLEVELALT (HA56) reports the level of hemoglobin in their blood, in terms of grams per deciliter (g/dl), based on testing of blood drawn by DHS personnel, and adjusted for altitude. Hemoglobin levels are tested to determine the presence and severity of anemia. HWFHEMOLEVELALT is a 3-digit variable with 1 implied decimal place.

The USAID publication Adjusting Hemoglobin Values in Program Surveys [URL omitted from DDI.] explains, "At elevations above 1000 m. hemoglobin concentrations increase as an adaptive response to the lower partial pressure of oxygen and reduced oxygen saturation of blood." The report further provides an equation for adjusting hemoglobin values in altitudes at 500-meter intervals, and explains that adjustment is important because "WHO hemoglobin cutoffs for anemia refer to sea-level values."

For a summary statement of the female household member's anemia status, based on grouped hemoglobin level results, see HWFANEMIALVL (HA57).
