Home-Grown School Feeding: Implementation Lessons From a Pilot in a Poor Ethnic Minority Community in Vietnam.

BACKGROUND: Undernutrition threatens the health and future of preschool children in disadvantaged remote communities. Home-grown school feeding (HGSF) in nursery schools could positively impact children's nutrition while creating multiple benefits for the whole community. However, evidence is lacking on implementation of HGSF within multi-sectoral programs in remote areas. OBJECTIVE: This study assessed an HGSF pilot intervention, part of a nutrition-sensitive agriculture (NSA) program, in a mountain ethnic minority community in Vietnam. It aimed to identify the changes brought about by the intervention, in particular diversity of children's food, food sources, barriers and facilitators to change, and future challenges and strategies. METHODS: Mixed-methods assessment covered school meal diversity, cost, and food sources but the key focus was on observed changes resulting from the HGSF intervention and perceived barriers and facilitators to its implementation. Data were collected mainly through semi-structured interviews (n = 30) and seven focus group discussions (n = 76). RESULTS: School meals contributed to increasing diversity of food consumed by children. Above 30% of foods used were home-grown. Respondents reported increased school attendance; children's food preferences and hygiene practices improved as did parents' caring and feeding practices. Local food systems became less cash-crop-oriented and more self-reliant, contributing to household food security and income generation. Social capital increased. Positive changes were attributed to HGSF and synergy among NSA program components. Poverty and limited resilience to external shocks threatened sustainability. CONCLUSIONS: Implementing HGSF within an NSA program in a mountainous ethnic minority area with a high prevalence of undernutrition benefitted children and their communities.

Qualitative evidence for improved caring, feeding and food production practices after nutrition-sensitive agriculture interventions in rural Vietnam.

Background: Research on nutrition-sensitive agriculture (NSA) has mostly been aimed at demonstrating its impact on nutrition and explicating underlying pathways, and more rarely at understanding processes and lessons learnt from them. This study aimed to gain insights into the processes that influence behaviour change, contributing to improved caring, feeding and food production practices, using a program theory perspective. It also investigated perceived challenges to the sustainability of interventions and potential solutions, in the context of an NSA program in rural Vietnam. Using a participatory approach, data were gathered on impact pathways and perceived outcomes, on elements of program theory that led to behavioural change, as well as barriers and facilitators. Respondents in semi-structured interviews (n = 30) and seven focus group discussions (total n = 76) were selected purposively among program participants. Data was collected and triangulated across several stakeholder groups. Results: The impact pathways (production-consumption, caring and feeding, and home-grown school feeding) envisaged in the NSA program functioned as intended; synergies were revealed. The increased supply of locally produced nutrient-rich foods not only contributed to the emergence of a promising income sub-pathway but also reinforced synergy with the home-grown school feeding pathway. Improved diets, feeding and caring practices, and school attendance were key outcomes of the program. Successful elements were pathway-specific, such as flexibility in implementing context-appropriate agricultural models. Others, such as benefit-driven motivation and improved knowledge, triggered changes in multiple pathways. Role models, increased self-confidence, and change agents were the main process facilitators. The biggest barrier to both implementation and sustainability was the poor socio-economic conditions of the most disadvantaged households. Conclusions: This study showed the relevance of NSA programs in addressing undernutrition in remote areas by enhancing self-reliance in local communities. The integration of behaviour change activities proved to be a key strategy in the process to enhance the impact of agriculture on nutrition outcomes. Though outcomes and influencing factors are very context-dependent, lessons on what worked and what did not work could inform the design and implementation of effective behaviour change strategies in future NSA programs in Vietnam and elsewhere.

Nutrition-Sensitive Agriculture: A Systematic Review of Impact Pathways to Nutrition Outcomes.

The role of agriculture in reducing undernutrition is widely recognized, yet there is also consensus on the need to make the sector nutrition-sensitive. Evidence on the impact pathways from nutrition-sensitive agriculture (NSA) interventions, agricultural interventions with specific nutrition objectives, and actions detailing each temporal stage to reach nutrition outcomes is limited, however. We thus synthesized study results regarding impact of NSA interventions on nutrition outcomes relating to undernutrition, and constructed an impact pathway by mapping the evidence on each temporal stage from interventions to nutrition outcomes. We used Preferred Reporting Items for Systematic Reviews and Meta-Analyses to conduct and report our systematic review of studies on NSA interventions implemented in low- and lower-middle-income countries. Forty-three studies that met the inclusion criteria were extracted and synthesized across impact and pathways analyses. We carried out a thematic analysis of the effect of NSA interventions using evidence-based indicators and constructed the pathways by adopting a published framework on agriculture to nutrition pathways. Our findings reveal that NSA interventions can significantly improve dietary practices, and have the potential to enhance care practices and reduce occurrence of diseases, indicating their effectiveness in simultaneously addressing multiple determinants of undernutrition. However, NSA interventions have a lesser impact on nutritional status. NSA interventions lead to nutrition outcomes through 5 key pathways: food production, nutrition-related knowledge, agricultural income, women's empowerment, and strengthening of local institutions. We emphasize the need to carefully design, implement, and evaluate interventions with consideration for factors affecting impact pathways. Future research should focus on the effect of interventions combining multisector components, and pathways through non-food-production-related income, women's empowerment, strengthening of local institutions, food prices at intervention level, and expenditure on health care.
