Santal Nutrition Connect: Design an inclusive last mile for nutrition

Maternal and child nutrition is shaped by interacting causes: household resources, maternal health, child-feeding practices, dietary diversity, service access and communication. An information service can support practical decisions and follow-up, but it cannot create affordable food, diagnose anaemia or replace health care. The management question is where better communication could help an existing service work more effectively for households.

Stiller and colleagues' published Birbhum study reports substantial undernutrition in a sample of Santal children. Its findings justify careful attention, but they are historical and local. They should not be presented as current prevalence for every Santal community. The proposed feasibility stage would establish current needs, variation between villages and the service capacity available to respond.

Government documentation describes POSHAN Tracker as a service-monitoring and governance tool that digitises Anganwadi records. A parallel system for attendance or growth records would duplicate work and increase burden. Santal Nutrition Connect instead proposes understandable household communication, locally relevant food knowledge and two-way contact with existing workers, subject to local programme agreement.

The distinction matters operationally. Clinical measurements and referral decisions would stay with qualified workers and recognised services. The proposed tool would help explain approved messages, remind consenting households about activities and connect questions to a responsible person. Any necessary service record would remain in the authorised system; household-facing content would collect as little personal information as practical.

The initial design combines downloadable audio and images, short Santali and Bengali explanations, worker-assisted demonstrations and locally reviewed food examples. Shared access would be available for households without a suitable device. Content would be checked for seasonal availability, affordability, cultural meaning and nutritional appropriateness. A recipe that requires inaccessible ingredients is an operational failure even if its message is clear.

Rao and colleagues' participatory filmmaking research provides relevant evidence for community-generated communication and the visibility of Indigenous knowledge. It does not prove the proposed Birbhum service will change diets. Local youth, caregivers, elders and workers would help decide which knowledge to record, how to represent it and what may be shared. Participation and consent would remain voluntary.

A smartphone-only application is easy to distribute digitally, but could miss households facing device, connectivity or literacy constraints. In-person communication alone supports trust while placing more demands on limited worker time. A hybrid model combines community sessions and worker support with reusable offline content, preserving human contact while allowing messages to be revisited.

The hybrid is the recommended test. Rogers' diffusion framework helps organise adoption questions: is there a visible advantage, does the service fit local practices, is it understandable, can households try it and can they observe useful effects? These are research questions rather than assumptions of acceptance. Worker time and continuity of content maintenance are as important as technical usability.

A feasibility pilot should measure who is reached, whether messages are understood, what questions remain and whether agreed service connections are completed. Examine participation by device access, language and household circumstances. Record additional worker minutes, unresolved questions, offline failures and reasons for non-use. Voluntary non-participation should not reduce access to existing nutrition services.

A later evaluation could examine dietary diversity or nutrition outcomes only with qualified partners, an appropriate comparison design and sufficient follow-up. Seasonality, food availability, illness and concurrent programmes complicate attribution. The programme budget should include community facilitation, compensation, translation review, training, equipment support and content renewal; downloads alone do not constitute a useful public-service investment case.
