Anemia is an important component related to mortality and morbidity as far as MCH(Maternal and Child Health) care is concerned. So, accurate estimates are needed to tackle the crisis. 

 Comparing data of NFHS-4(2015-16) and NFHS-5(2019-21) anemia burden in India increased by nearly 4% and 8% in women of reproductive age group and children of age 6 to 59 months.

This created fear of over diagnosis of anemia in India. 

The method already followed in NFHS uses capillary blood(diluted one) for Hb estimation rather than venous blood which is more accurate. Hence questions related to anemia are dropped from NFHS-6 which is scheduled to commence in July. 

Diet and Biomarkers Survey in India (DABS-I) launched last year to map diet, nutrition and health status, shall provide the correct estimate of anaemia among the rural and urban population.
