Abstract
Malnutrition is pervasive in Uganda, with about 30% of children experiencing stunted growth. This is linked to a lack of knowledge of good nutrition practices and social norms limiting the consumption of certain foods for vulnerable members. These challenges are most prevalent in the consumption of ASFs. In this study, we implement a combination of gender-differentiated interventions to improve the nutritional outcomes of children and mothers. In our baseline treatment (WN), we deliver a nutrition knowledge module similar to a standard Village Health Team (VHT) nutrition package, as captured by the MIYCAN Counselling Cards of the Ugandan Ministry of Health. This is only administered to women. The second treatment (WmenN) arm receives a similar nutrition knowledge intervention for males. In the third arm (WmenNSN), we implement an intervention that goes beyond the provision of knowledge and changes behaviors and social norms regarding ASF consumption. This is administered to both men and women. We test the impacts of WNSN and WmenNSN relative to the WN through a clustered randomized controlled trial.

Interventions

Intervention(s)
Our project aims to improve the nutritional and dietary behaviors of children and mothers in central Uganda through a series of gender-specific information campaigns. These campaigns are designed to address both nutritional education and social norms within households. We implement the following interventions:
1. Women in the household receive nutrition information sessions - baseline intervention
2. Women and men in the household receive nutrition information sessions
3. Women and men in the household receive information on social norms surrounding food distribution within the household, in addition to nutrition information sessions for both men and women.

Primary Outcomes

Primary Outcomes (end points)
Minimum Dietary Diversity, Consumption of protein-rich ASFs, Nutrition knowledge, Prevalence of social norms
Primary Outcomes (explanation)

Secondary Outcomes

Secondary Outcomes (end points)
Household food expenditure, household non-food expenditure, participation in household activities, consumption of other food groups, and
share and value of farm output consumed by households. We will also analyze other intermediate variables, including education and related expenses, healthcare, sickness, and employment, VHT visits.
Secondary Outcomes (explanation)

Experimental Design

Experimental Design
The central objective of this project is to evaluate the differential treatment effects between the two treatment groups and the control group (baseline intervention). Given that treatment assignment is random, a straightforward comparison of outcomes across treatment groups will provide us with the impact on respective outcomes. The intervention is conducted in two regions in Central Uganda, within each region villages were randomly assigned to one of the three treatment groups:
- T0: Information campaigns on nutrition only to women - control group
- T1: Information campaigns on nutrition to women and men.
- T2: Information campaigns on nutrition and social norms to women and men
