TFRC and anemia (phenotype): Among boys, neither ferritin—the WHO recommended indicator to assess iron status in populations (WHOa, 2017)—nor iron deficiency defined by ferritin varied by anaemia status in bivariate analyses; however, sTfR was associated with anaemia in both bivariate and multivariable analyses, suggesting that iron may have some contribution to anaemia burden among adolescent boys in Nepal.
