IL6 and anemia (phenotype): The ratio of anemia due to ID (Ferritin <12 ng/mL) or inflammation (IL-6 > 60 pg/mL) was estimated using adjusted Poisson regression models, reporting prevalence ratios (PR).<h4>Results</h4>Applying the new WHO guidelines, anemia prevalence changed from 50% to 42.2% in children aged 6-59 months (62% to 47% in children aged 6-23 months and from 45.9% to 40.6% in children aged 24-59 months).
