Tamil Nadu’s child health system is moving beyond the narrow measure of keeping children alive, but the state’s own data and officials’ remarks show that survival has not automatically translated into healthy growth and development. The challenge now is whether screening, referral and therapy systems can follow vulnerable children all the way from identification to treatment.
Health minister K G Arunraj set out this shift at a workshop organised by the Press Information Bureau and Unicef. He cited National Family Health Survey 6 data for 2023-24, which showed that wasting among children under five rose from 14.6% in the previous survey round to 17.4%, even as stunting declined from 25% to 20.7%. Tamil Nadu’s infant mortality rate was 11 per 1,000 live births in 2024, compared with 24 for India.
These figures present a more complicated picture than a simple improvement-or-decline narrative. The fall in stunting and the state’s lower infant mortality rate point to progress in preventing long-term growth restriction and early deaths. The increase in wasting, however, indicates that acute nutritional vulnerability remains a problem. The figures cited by the minister therefore place survival, growth and development in the same policy frame rather than treating them as separate health-sector concerns.
That distinction matters because a child can survive infancy while still requiring support for nutrition, developmental delays, birth defects or other health conditions. The state’s response, as described in the report, is to identify such needs earlier and connect children to services before gaps become visible only at school admission.
Tamil Nadu currently has 805 mobile health teams that screen children and refer those needing further care to 34 district early intervention centres. Village health nurses and anganwadi workers are expected to monitor development during the first 1,000 days of life. The stated aim is to detect delays at around 18 months rather than wait until a child enters school.
This is an important change in the location and timing of detection. School admission is a late point at which to discover a developmental difficulty. By then, the child may already have passed through several stages of early development without assessment or therapy. The first 1,000 days framework places more responsibility on frontline workers and local health systems, where children are routinely encountered through anganwadi services, vaccination visits and household-level public health work.
But early identification is only the first link in the chain. Arunraj acknowledged this directly when he said, “A delay identified at an anganwadi and never seen at the intervention centre is not a success. It is a child we found and then lost.” The statement shifts the measure of performance from the number of children screened to the number who actually receive an appropriate follow-up.
That distinction exposes a common institutional problem in public service delivery: activity can be recorded even when the intended outcome is not achieved. A screening visit, a referral entry or a flagged case may demonstrate that the system is functioning at one point. It does not establish that the child reached a specialist, received therapy, continued treatment or was formally assessed as not requiring intervention.
The department’s proposed response is to publish how many children who were flagged received therapy and how quickly they received it. According to the minister, these are the numbers he would seek from officers and invite the public to ask him for. If implemented, such reporting would make the referral chain more visible and create a distinction between coverage and completion.
The pilot programme in Tiruvallur illustrates how this model can work at the point where families already interact with the health system. Growth and developmental checks were added to routine vaccination visits in Gummidipoondi and Ellapuram. Between March and July, health workers screened 2,756 of the 2,773 children who attended vaccination sessions in the two blocks.
The screening coverage was therefore nearly comprehensive among children attending those sessions. The teams flagged 39 children for further assessment. Of these, 19 had growth faltering, nine had developmental delays, another nine had birth defects and two had diseases, according to state National Health Mission additional director Dr K Vinay Kumar.
All 39 children were referred. The outcomes recorded included treatment, continued observation and assessments that found a child to be normal. This detail is significant because referral does not always lead to a diagnosis or therapy. Some cases may require monitoring, while others may be assessed and found not to need treatment. A credible system must be able to record all three outcomes rather than assume that every referral produces the same result.
The pilot also demonstrates the value of linking screening with an existing service instead of creating an entirely separate contact point for families. Vaccination sessions already bring children and caregivers into the public health network. Adding growth and developmental checks to those visits allows the system to use an established interaction to identify additional needs.
At the same time, the figures should not be treated as a complete picture of child health across Tamil Nadu. The screening covered children who attended vaccination sessions in two blocks, not every child in the state. The report does not establish how many children did not attend those sessions, how many referred children completed therapy, the time taken for each intervention or whether outcomes differed by location or socioeconomic condition.
Those gaps are central to understanding the state’s next administrative challenge. A network of mobile teams and district intervention centres creates the infrastructure for detection and referral, but the effectiveness of that network depends on what happens between the first screening and the final recorded outcome. That includes communication with families, transport to facilities, specialist availability, therapy capacity and follow-up by frontline workers. The supplied report does not provide figures for those stages.
The proposed outcome reporting could help answer some of these questions. Reporting the number of flagged children who received therapy would show whether referrals are being completed. Reporting how quickly they received care would add a time dimension that is essential for developmental interventions. Without those measures, a system may appear active while leaving the most important part of the process invisible.
This is also why the contrast between wasting and stunting matters for administration. The NFHS-6 figures cited at the workshop show improvement in one indicator and deterioration in another. The figures do not, by themselves, explain the causes of that divergence. They do show that a single headline measure cannot capture the full condition of children under five. A state can record lower infant mortality and lower stunting while still facing a higher prevalence of wasting.
For local health administrators, that means the task is not limited to expanding survival services. It involves connecting nutrition monitoring, developmental screening, referral systems and early intervention. The institutional responsibility is distributed across mobile health teams, village health nurses, anganwadi workers, district intervention centres and the National Health Mission. The minister’s emphasis on publicly reporting outcomes suggests an attempt to connect those separate functions through measurable follow-up.
The approach also raises a broader question about how public systems define success. Counting the number of children reached is easier than tracking whether a child received care. Screening numbers can demonstrate scale, but they cannot substitute for case closure, treatment completion or continuing observation. The Tiruvallur pilot’s recording of treatment, observation and normal assessments points towards a more detailed system of accountability, although the report does not indicate how consistently that framework is being applied beyond the pilot.
Tamil Nadu’s experience therefore sits at the intersection of health infrastructure and governance. The state has a large screening network and district-level early intervention centres, but the central test is whether information moves reliably across those institutions. A child identified by one worker must remain visible to the next service, and the final outcome must return to the system that first identified the concern.
The evidence currently confirms three things: Tamil Nadu has made substantial progress on infant survival relative to the national figure cited; stunting has declined while wasting has increased; and the state is attempting to detect developmental and health concerns earlier through frontline screening and vaccination-linked checks. What remains to be established is the scale and speed of completed therapy across the full system. That is the measure the health department has said it intends to publish, and it will determine whether early screening becomes sustained care rather than another incomplete referral chain.
