Anaemia and its severity by haemoglobin (WHO 2024)
who2024_anaemia@1.0Table 3: Adults, 15–65 years, nonpregnant women: No anaemia ≥120; Mild 110–119; Moderate 80–109; Severe <80. Adults, 15–65, years men: ≥130; 110–129; 80–109; <80 (g/L)
World Health Organization, Guideline on haemoglobin cutoffs to define anaemia in individuals and populations (2024) · Executive summary: Table 2 (PDF page 12), Table 3 (PDF page 13), Table 4 (PDF page 14), Table 5 (PDF page 15) · source
Contested: Cut-offs are 5th percentiles of mostly higher-income populations (WHO's own remark); the men's 130 g/L cut-off and severity percentages were debated by the guideline group; CTCAE and laboratory reference ranges use other limits; older adults (>65) are not covered.
Not encoded: The elevation formula (0.0056384 x elevation + 0.0000003 x elevation²) is not used; the 500 m table rows are. The remark that tailored adjustments may be warranted above 2500 m is not encoded. Adjustment for inflammation/infection (malaria) and for genetic ancestry: WHO recommends none (normative statements 2.b and 2.c); nothing is applied. Type and cause of anaemia (iron deficiency, blood loss, haemolysis) are not assessed. Persons older than 65 years and infants under 6 months: Table 2 gives no cut-off, so they are not assessable. Exactly 20 cigarettes per day: Table 5 lists '10–19' and '>20', so 20 per day is outside the table and not assessable (source gap).
