Nowadays, her routine consists of one thing newer and stranger: recording movies of new child infants.
“Earlier we needed to carry weighing scales and tapes, which was tough. Now, we simply carry the cellphone and it exhibits us the newborn’s weight. Even in small villages, we are able to do correct measurement simply,” she says.
Patel is referring to Shishu Mapan, a synthetic intelligence (AI) instrument educated on over 30,000 infants, constructed by scientists on the Wadhwani Institute for AI, a non-profit that develops AI-based solutions for social impression.
Utilizing a brief, arc-shaped video whereas the new child is undressed and laid on a fabric sheet, the app estimates the toddler’s weight and progress metrics, which eliminates the necessity for scales or guesswork.
Initially sceptical, employees and moms gained belief as soon as the app confirmed correct readings.
“Once we first advised moms we’d measure the kid utilizing a cell phone, they thought we had been joking. However after they noticed the video and the load appeared on the app, they had been blissful. Now they lay the sheet down themselves and wish to see if their child has gained weight,” says Patel.
Whereas most infants are weighed at beginning, follow-up checks in the course of the essential first six weeks are patchy, particularly in rural and underserved areas. On this context, AI-powered instruments like Wadhwani AI’s app may change into frontline necessities, able to remodeling youngster well being outcomes the place the system typically falls quick. It additionally eases the burden on frontline well being employees, who typically wrestle to maintain up with excessive demand in rural areas.
Low beginning weight, outlined as infants weighing lower than 2.5kg at beginning, is among the most severe purple flags in early childhood well being. These infants face the next threat of stunting, frequent infections and life-threatening malnutrition. Circumstances similar to marasmus, marked by excessive losing as a result of calorie deficiency, or Kwashiorkor, brought on by protein deficiency and leading to swelling, liver injury and immune suppression, are tragically widespread when detection is delayed. Correct progress monitoring within the first six weeks is usually the one probability to intervene earlier than it’s too late.
“ASHA employees are overworked, their instruments are outdated and there’s no digital record-keeping,” says Alpan Raval, chief scientist at Wadhwani institute of AI.
AI-powered solutions offer a way forward, offering correct and offline-friendly instruments that ease the burden on frontline employees and convey consistency to youngster well being assessments.
Shishu Mapan started in 2019, when the Gates Basis approached the institute with a problem to develop an answer to precisely weigh low-birth-weight infants in rural India. After years of analysis and subject testing, the pilot lastly launched in Daman and Diu final yr.
Throughout India, a new crop of AI-based tools is being deployed to deal with persistent challenges in monitoring early childhood growth, significantly in low-resource settings. MAAP (Malnutrition Evaluation and Motion Plan) by social enterprise RevolutionAIze makes use of smartphone photographs to estimate peak and flag malnutrition dangers. Researchers at IIIT-Hyderabad are testing a dual-photo methodology to estimate each peak and weight utilizing fundamental visible cues. The Little one Development Monitor, developed by Welthungerhilfe with Microsoft, makes use of infrared 3D sensors to scan younger youngsters for anthropometric (measurement of the human physique) evaluation.
Every of those tasks is totally different in scope, age vary and technical complexity, however they share a common approach of rethinking youngster well being infrastructure via accessible AI that may be utilized on a big scale in densely populated areas.
Digital repair for a systemic hole
Neonatal healthcare in rural India faces challenges of entry, affordability and consciousness. Wadhwani’s instrument tackles this hole via early intervention. As soon as a child is discharged from a hospital, the dad and mom solely return for immunizations after six weeks, leaving underweight newborns uncovered to well being dangers. To deal with this blind spot, India’s House-Based mostly New child Care (HBNC) programme requires ASHA employees to conduct residence visits throughout this era. ASHA employees typically assist determine underweight infants and in addition join new moms with authorities diet programmes. These programmes are important to stop low beginning weight spiralling into power undernutrition. However when weight knowledge is lacking or inaccurate, these security nets typically miss essentially the most susceptible.
The instruments out there to ASHAs, similar to sling-based Salter spring balances, should not fitted to this use case.
“The needle sparkles and ASHA employees wrestle to get a steady studying,” explains Dr. Sneha Nikam, a public well being skilled at Wadhwani AI. “That makes it arduous to detect points early or take well timed motion.”
The Shishu Mapan app is a straightforward resolution the place an ASHA employee locations the newborn subsequent to a wood ruler, data a brief video and lets the cellphone do the remainder. The app maps the newborn’s key factors and calculates weight, size and head circumference. The mannequin, optimized to run on low-end Android telephones and tolerate imperfect lighting or movement, works in offline mode while not having the web or cloud storage, making it efficient in rural areas with poor connectivity.

Raval says the preliminary growth of the undertaking started in hospitals the place managed lighting and backgrounds allowed the staff to show that the core thought of estimating weight from video was viable. Discipline deployment, nevertheless, required tweaks. As an illustration, as a substitute of a checkerboard for visible calibration, Wadhwani used a wood ruler that ASHA employees already carried.
Some dad and mom raised privateness considerations throughout checks, which the staff ultimately dealt with by storing movies regionally and deleting them after processing.
“We tried constructing a mannequin that would work on blurred faces, nevertheless it didn’t work. The AI would overestimate measurement,” he admits. The staff ultimately discovered a compromise the place movies are saved regionally and deleted instantly after processing. Solely inner annotators, certain by NDAs and dealing in safe rooms, see the uncooked footage.
In early 2024, the app was piloted in Daman and Diu. Native well being authorities built-in it into their PHMP (Proactive well being administration plan) platform, changing handbook weight entries.
The app’s margin of error, round 114 grams, is considerably decrease than spring balances, which might range by 183 grams. To account for attainable over or underestimation, ASHA employees are instructed to refer infants even when their readings are barely above or beneath thresholds.
“If the AI says 1.9 kg, we nonetheless refer it to native hospitals, as a result of it may truly be a 1.8 kg child,” says Nikam. Though it’s too early to evaluate the long-term impression on well being outcomes, preliminary suggestions suggests a shift in how early progress monitoring is being approached.
In line with Nikam, having digital logs provides to the accountability of ASHA workers and in addition gives a clearer image. The rise in well timed referrals helps set off earlier interventions in areas similar to diet and sanitation.
Increasing AI instruments’ ecosystem
Whereas Wadhwani’s instrument focuses on the new child stage, MAAP picks up the place it leaves off—monitoring youngsters from six months onward.
Developed by social entrepreneur Romita Ghosh and knowledge scientist Nilashis Roy beneath their social enterprise RevolutionAIze, MAAP makes use of a single smartphone picture to estimate peak, assess dietary standing and counsel tailor-made meal plans.

“Over 3.5 million severely malnourished youngsters in India go unscreened,” says Ghosh. “MAAP helps well being employees catch early indicators even within the remotest corners.”
Constructed for comparable working circumstances in rural India, MAAP’s instrument additionally works offline and is prop-free. The staff experimented with rulers, checkerboards and even Bisleri bottles for calibration earlier than instructing the AI to estimate scale from posture and environment.
Early challenges like poor lighting and picture angles led to a field-tested MAAP Guide and vernacular coaching movies. Ghosh says co-designing with ASHA and Anganwadi employees was important. “We didn’t simply construct it for them. We constructed it with them,” she says.
MAAP is free for presidency employees, whereas personal suppliers pay. This cross-subsidy helps hold the product sustainable.
The information collected via the instrument is anonymized and doesn’t retailer any faces. The algorithm, alternatively, is continually up to date to replicate regional variety in physique proportions and pores and skin tones. Ghosh says the mannequin has earned international consideration with invites to current on the WHO and the AI for Good International Summit in Geneva.
In Telangana, IIIT-Hyderabad researchers are testing a dual-photo app that estimates peak and weight utilizing markers similar to wall charts and scale shows. Nonetheless within the pilot part, it exhibits potential for institutional settings however requires tighter protocols. In the meantime, the Little one Development Monitor developed by Welthungerhilfe and Microsoft makes use of 3D infrared cameras to create full-body scans of kids beneath 5. The mannequin is correct and hardware-driven, however its excessive price and dependency on sensors restrict its subject adaptability.
The highway forward
Wadhwani AI’s subsequent step is to broaden its anthropometry mannequin to cowl youngsters as much as six years previous. Prasaanth Balraj, product supervisor on the institute, who additionally oversees its work on tuberculosis and maternal well being, advised Mint that the ministry of girls and youngster growth has requested this enlargement to combine the instrument with the Poshan Tracker, India’s nationwide child nutrition knowledge platform.
“This may require retraining the mannequin to precisely assess older youngsters, whose motion patterns and physique proportions differ considerably from newborns,” says Balraj.
Wadhwani AI can also be making ready to roll out pilots in different states, with Arunachal Pradesh among the many first. The staff has begun the method of contextualizing the mannequin for regional variations in lighting, pores and skin tone and toddler look. Discipline groups are supporting this with coaching, technical setup and suggestions loops.
“In lots of testing websites, that is the primary time we’re seeing such knowledge on toddler progress being captured and shared upward in close to actual time,” says Balraj.
For Romita Ghosh, whose work via MAAP focuses on the broader problem of figuring out malnourished youngsters, the long-term impression is dependent upon integrating AI into current public techniques somewhat than creating parallel ones.
“You don’t transfer mountains with tech alone. You do it with coverage, partnerships and persistence,” she says.
MAAP flags early malnutrition dangers and suggests meal plans tailor-made to native diets. By embedding the instrument into current authorities workflows and providing it free to public well being employees whereas subsidizing prices via personal companions, Ghosh says they’re aiming to “transfer the needle” on India’s malnutrition disaster.
Whether or not it’s MAAP’s pose-estimation mannequin, IIIT-Hyderabad’s dual-photo instrument or Wadhwani’s new child weight app, the instruments can have a bigger impression after they combine into the system. Therefore they’re being designed to work offline, on fundamental telephones and inside routines that frontline employees already comply with.
Scaling AI for healthcare
Sumedha Sircar, a public well being researcher with a public well being diploma from Harvard and founding father of Liger India, has labored extensively on deploying AI for cervical cancer screening in rural Bihar and Jharkhand.
“Anthropometry is less complicated. It ought to be attainable to construct dependable AI round it, particularly one that provides standardized, repeatable leads to rural settings,” she says.
Past accuracy, Sircar emphasizes the potential for AI to enhance knowledge reliability.
“ASHA employees are overburdened and sometimes have to fulfill targets. A smartphone instrument that requires visible inputs makes knowledge more durable to fudge than paper entries,” she says.

Sircar suggests increasing the ASHA workforce and utilizing AI to embed native coaching and suggestions loops, so employees can report points or share successes with out ready for top-down interventions.
Shally Awasthi, head of the paediatrics division at King George’s Medical college and a member of the World Well being Group’s advisory group, says AI-based interventions have enormous potential in detection of malnutrition and undernutrition in areas with restricted entry to educated paediatricians. In addition they have a task to play in areas manned by healthcare professionals who’re both too busy to concentrate on anthropometry and its interpretation and comply with up, or haven’t been educated in paediatrics, she says.
“AI intervention for detection have to be supported by amenities for motion and follow-up at a clinic near their residence,” says Awasthi. “The comply with ups can’t be accomplished successfully by AI as loads of private teaching and handholding might be wanted for a very long time.”
In different phrases, AI shouldn’t be a silver bullet. However it will possibly have a hugely positive impact on tens of millions of lives whether it is complemented by modifications in follow and coverage.
