The Real Reason India Dropped Anaemia From NFHS-6

Public health experts in India are questioning the omission of crucial health statistics. Specifically, the newly released National Family Health Survey (NFHS)-6 fact sheets do not contain any NFHS-6 anaemia data. Consequently, this absence has triggered a nationwide debate among clinicians and policy planners who track nutritional deficiencies.

Why is NFHS-6 Anaemia Data Handled Differently?

In previous rounds, survey teams used capillary blood sampling via finger-pricks to test haemoglobin levels. However, experts raised serious concerns that this portable method often overestimates the prevalence of anaemia. Therefore, the Ministry of Health decided to exclude haemoglobin testing from the latest NFHS round. Instead, the government will rely on a separate national initiative to collect this vital information.

The Shift to More Accurate Venous Testing

As a result, India will now rely on the Indian Council of Medical Research’s Diet and Biomarkers Survey. This specialised study utilizes gold-standard venous blood samples to evaluate nutritional health. Thus, clinicians can expect far more reliable and clinically precise statistics in the near future. Nevertheless, researchers caution that changing the testing methodology will make it harder to directly compare new findings with older data sets.

Other Key Health Indicators Under Monitoring

Moreover, officials clarified that the fact sheets represent only the initial stage of data dissemination. Additional indicators, including family planning, child health interventions, and maternal health measures, will appear in the final National Report. Meanwhile, other administrative databases will continue to monitor metrics such as sanitation, birth registration, and mortality. This coordinated strategy aims to reduce duplication and streamline national data collection.

Frequently Asked Questions

Q1: Why is there no anaemia data in the NFHS-6 fact sheets?

The health ministry omitted haemoglobin testing due to concerns that capillary blood sampling, which was used in previous rounds, can lead to inaccurate overestimations. Instead, they will use venous blood sampling in a separate survey.

Q2: How will India measure anaemia prevalence going forward?

The government will estimate anaemia prevalence using the Diet and Biomarkers Survey conducted by the Indian Council of Medical Research (ICMR), which employs more reliable venous blood testing methods.

Q3: Will the missing health indicators be released later?

Yes, several detailed health, maternal, and child indicators are not lost. They will be included in the comprehensive National Report to be published subsequently.
