简要总结
Pre-school undernutrition is a global problem with life long adverse consequences. One form of undernutrition, chronic undernutrition or stunting, affects 171 million children under the age of 5 worldwide. 35% of these children live in Africa. In Ethiopia, the focus of this study, in 2014, 44.5% of children under 5 were stunted. Stunting is the consequence of several factors including low birth weights, sub-optimal infant and complementary feeding practices and repeated illness. In Ethiopia, complementary feeding is sub-optimal; only 4% of children aged 6-24 months met the minimum dietary diversity recommended by WHO.
The investigators hypothesize four main reasons why many children and mothers in Ethiopia fall short of best practice in terms of meeting nutritional needs and providing appropriate childcare.
(i) Lack of information on healthy eating and appropriate child-feeding practices; (ii) Limited affordability; (iii) Limited accessibility to markets and diverse food items; and (iv) Limited peer effects in spreading information and adopting new practices.
This study will assess the efficacy of the interventions that address these four barriers to optimal complementary feeding practices in Ethiopia. Using a cluster randomized control design, mother-father-child pairs in two localities, Holeta and Ejere will be enrolled. Treatment will be randomized at the garee (village) level. There will be five treatment arms and a control group: T1, weekly maternal nutrition BCC sessions for four months; T2, weekly maternal nutrition BCC sessions for four months and weekly paternal nutrition BCC sessions for three months; T3, receipt of a food voucher for six months; T4, weekly maternal nutrition BCC sessions for four months and receipt of a food voucher for six months; T5 weekly maternal nutrition BCC sessions for four months and weekly paternal nutrition BCC sessions for three months and receipt of a food voucher for six months; and C, a control group. Within household, recipient of voucher (mother or father) will be randomly selected.
详细描述
- Specific Aim of the study
Aim 1: How does maternal behavior change communication (BCC) on healthy eating affect knowledge on child feeding, child feeding behavior, and nutritional status of the child? o Does BCC lead to changes in knowledge about healthy child-feeding and child-feeding behaviors?
o Does the changes in child-feeding behaviors due to BCC lead to improvements in nutritional status among young children measured by height-for-age and weight-for-height?
Aim 2: How do food vouchers affect food consumption and nutritional status?
- Do vouchers lead to increased food consumption and dietary diversity?
- Do vouchers crowd out private spending on food?
- Does the increased food intake due to food vouchers lead to improvements in nutritional status among young children measured by height-for-age and weight-for-height?
Aim 3: How does increased accessibility affect food consumption, child-feeding behavior and nutritional status?
- By sending petty traders of various food items to randomly selected markets with limited access to diverse food groups, the investigators hypothesize that increased accessibility to diverse food items will lead to increased food consumption and dietary diversity.
- Is there complementarity between accessibility and BCC or vouchers?
