Sponsored by Hosted by
Presented at the International Food Security Dialogue 2014
Enhancing Food Production, Gender Equity and Nutritional Security in a
Changing World
Under-nutrition measures for women and children in Africa and Asia
2. The Fish on Farms project is being jointly conducted by the University of
British Columbia (UBC) and Helen Keller International (HKI), with technical
assistance from World Fish, in Prey Veng Province, Cambodia.
This randomized control trial investigates an integrated Homestead Food
Production models in relation to poverty, gender empowerment, and food
and nutrition security, particularly among women and children.
This is the first project known to rigorously measure the effectiveness of
different models of Homestead Food Production at reducing undernutrition
using biochemical and anthropometric measurements.

4. Karen People of Mae La Refugee Camp
• Thai-Burmese border; settled in
1986
• High infant mortality rate
unrelated to major killers
• diarrhea and respiratory illness
• Between 1987 – 1990, infantile
beriberi caused 40% of all
infant deaths
McGready et al 2001; Luxemburger et al 2003; Stuetz et al 2012
5. Background: Thiamin
• Vitamin B1
• Thiamin diphosphate (TDP)
plays major role in carbohydrate
metabolism
• Pentose-Phosphate Pathway
• Kreb’s Cycle
• Modulates neuronal and neuro-
muscular transmissions
Images from: Beltramo, E (2011)
6. Infantile beriberi
• Stems from thiamin (vitamin B1)
deficiency
• Symptoms
• signs of right-sided heart failure
• rapid breathing
• generalized edema
• distinctive, hoarse cry
• Presents around 3 months of age
• Infant AI: 0.2 mg/day
• AI based on [breast milk thiamin] from apparently replete
women
• Root cause: maternal thiamin deficiency

19. Rationale
Need to improve maternal thiamin status to decrease the
incidence of infantile beriberi
Infantile Beriberi
• change dietary behaviours
• supplementation
• food fortification

29. Potential Significance
• Potential to significantly decrease thiamin deficiency in
Cambodia, which in turn will lower the risk of infantile beriberi
• Possibility of scaling up the production and distribution of
fortified product throughout Cambodia
• Potential for multiple micronutrient fortification; for example:
riboflavin
