Interventions
The foundational intervention approach
Nutrition-specific interventions or programs address the immediate determinants of nutrition status. For UPAVAN, this means age-appropriate feeding practices and adequate nutrient intake for children, maternal care to ensure rest and optimal nutrition, and care during child illness [7]. | |
Nutrition-sensitive agriculture addresses the underlying causes of undernutrition and incorporates specific nutrition goals. For UPAVAN, this means increasing physical, economic, and socio-cultural access to nutritious food year-round; increasing resources for health and nutrition at individual and household levels; improving women’s decision-making in agriculture activities, time use, and use of income; and reducing workload for pregnant and lactating women. Nutrition-sensitive agriculture does no harm to humans or the environment |
UPAVAN interventions
-
Two facilitated group meetings per month per group over 32 months, of varying content between arms, that are run by local, trained, paid facilitators.
-
In at least half of the meetings (all meetings in AGRI; half of the meetings in AGRI-NUT and AGRI-NUT+PLA), groups will view and discuss NSA videos on a pre-defined set of prioritised practices.
-
Follow-up visits to all participating pregnant women and mothers of children aged 0–23 months after each video viewing, or PLA meeting where applicable. The purpose of these visits is to maintain rapport with the participant, check if the participant recalls or has adopted the key practices discussed in the video, reinforce messages shown in the videos and clarify if needed, when relevant strengthen the link between participants and community frontline workers, and encourage attendance at the next meeting.
-
AGRI. Women’s groups view and discuss two NSA videos each month, following the foundational approach.
-
AGRI-NUT. Women’s groups view and discuss two participatory videos each month, following the foundational approach but with 50% of the videos covering NSA topics (half of the videos shown in the AGRI arm) and 50% covering nutrition-specific behaviour change topics.
-
AGRI-NUT+PLA. Each month, women’s groups view one NSA video (half of the videos from the AGRI arm) and have one PLA meeting on nutrition-specific topics. Some of these PLA meetings are discussion-based and some are facilitated disseminations of videos on nutrition-specific topics. The videos produced in this arm arise out of relevant discussions from the PLA meetings and so are different from the nutrition-specific videos in AGRI-NUT that use the foundational approach of identifying content described earlier. Facilitators will also only conduct follow-up visits when relevant — that is, after all NSA videos and PLA meetings that contain clear nutrition-specific messages.
Intended coverage
Impact evaluation
Trial outcomes
-
Percentage of children (6–23 months of age) consuming ≥ 4 out of 7 food groups per day, based on a 24-h dietary recall answered by the mother or female primary caregiver
-
Mean maternal BMI (kg/m2) of non-pregnant, non-postpartum (gave birth > 42 days ago) mothers or female primary caregivers of children aged 0–23 months
-
Percentage of mothers or female primary caregivers consuming ≥ 5 out of 10 food groups per day, based on a 24-h dietary recall
-
Percentage of children with a weight-for-height z-score < -2 SD
