The recently released National Family Health Survey (NFHS)-6 Fact Sheets have sparked intense debate among public health professionals in India. Surprisingly, the newly published documents omit the critical NFHS-6 anaemia data. Consequently, several experts raised questions regarding this sudden exclusion. However, the Union Health Ministry quickly clarified that the exclusion stems from methodological changes aimed at ensuring data accuracy.
In previous survey rounds, researchers estimated haemoglobin levels using the capillary finger-prick blood sampling method. Nevertheless, many scientific experts argued that capillary sampling often leads to skewed or overestimated anaemia prevalence rates. Therefore, the government decided to suspend this practice for NFHS-6 to prevent data errors. Instead, future anaemia estimates will rely on venous blood samples, which experts consider the gold standard for haemoglobin estimation.
To fill this diagnostic gap, the government will use data from the Indian Council of Medical Research (ICMR)’s Diet and Biomarkers Survey. Because this specialized survey utilizes venous blood samples, it will provide much more reliable and accurate clinical estimates. While some public health experts worry about the lack of immediate comparability with NFHS-5, the government maintains that data quality remains the highest priority. Thus, the new methodology will establish a far more robust baseline for future public health programs.
Importantly, officials rejected any claims that they permanently dropped key public health indicators. Currently, the ministry is working to streamline India’s statistical systems by routing indicators to the most authoritative source. For example, dedicated systems like Swachh Survekshan Grameen track sanitation and clean cooking fuel. Concurrently, NFHS-6 has introduced several new indicators, including antenatal care utilization, financial inclusion, and elderly population share.
Q1: Why was the NFHS-6 anaemia data excluded from the latest fact sheets?
The government excluded the data due to accuracy concerns surrounding the capillary blood sampling method used in earlier rounds. Instead, anaemia estimates will be sourced from a dedicated ICMR survey utilizing venous blood samples.
Q2: Will the final NFHS-6 report contain child health and family planning details?
Yes. The released fact sheets represent only the first stage of data dissemination. The upcoming comprehensive National Report will include detailed family planning indicators, child health interventions, and women’s health parameters.
Q3: Which survey will provide the new anaemia estimates for India?
The Indian Council of Medical Research (ICMR)’s Diet and Biomarkers Survey (DABS) will provide the updated anaemia estimates using the more accurate venous blood sampling method.
