Assumptions on reasons for the stagnation:
•Increase in inequity (increase in Gini coefficient)
•Reduction in infant mortality rate resulting in more infants surviving but
with malnutrition

On the Causes of Malnutrition
Population increases in a geometric ratio, while the means of subsistence increases in an arithmetic ratio
Thomas Malthus (1766-1834)

•Close to 27% or 40 million live in urban areas
•About 40% of Dhaka city population lives in slums•Dhaka is the fastest growing city

On the Causes of Malnutrition
Famine and malnutrition are a result of a collapse of entitlements for a certain segment of society and the failure of the state to protect those entitlements.
Amartya Sen

Evidence-Based Interventions

Interventions with Sufficient Evidence to Implement in All Countries
Maternal and Birth Outcomes• Iron folate supplementation• Maternal supplements of multiple micronutrients• Maternal iodine through iodization of salt• Maternal calcium supplementation• Interventions to reduce tobacco consumption or indoor air pollution
Newborn Babies• Promotion of breastfeeding (individual and group counseling)
Infants and Children• Promotion of breastfeeding (individual and group counseling)• Behavior change communication for improved complementary feeding• Zinc supplementation• Zinc in management of diarrhea• Vitamin A fortification or supplementation• Universal salt iodization• Handwashing or hygiene interventions•Treatment of SAM

Hygiene interventions: Reduce incidence of diarrhea by 30%, reduce odds of stunting
Bhutta ZA, Ahmed T et al. Lancet 2008
![Page 33: Ahmed 1 the food and nutrition situation in bangladesh](https://reader033.fdocuments.net/reader033/viewer/2022061200/5473f93bb4af9fbe0a8b565b/html5/thumbnails/33.jpg)

To eliminate stunting in the longer term, these Interventions should be supplemented by improvements in the underlying determinants of undernutrition, such as
poverty, poor education, disease burden, and lack of women’s empowerment.
![Page 36: Ahmed 1 the food and nutrition situation in bangladesh](https://reader033.fdocuments.net/reader033/viewer/2022061200/5473f93bb4af9fbe0a8b565b/html5/thumbnails/36.jpg)
Recommendations
• Business as usual will not work• Need to think out of the box now• There is no one size that fits all, several
strategies need to be tried
![Page 37: Ahmed 1 the food and nutrition situation in bangladesh](https://reader033.fdocuments.net/reader033/viewer/2022061200/5473f93bb4af9fbe0a8b565b/html5/thumbnails/37.jpg)
Recommendations
• Immediate need is to improve existing services and scale them up– Primary health care focusing on child & maternal
health and nutrition should be priority– Increase number of centers, staff– Improve quality of counseling– Rigorous monitoring of quality of services to
reduce dissatisfaction with existing services
![Page 38: Ahmed 1 the food and nutrition situation in bangladesh](https://reader033.fdocuments.net/reader033/viewer/2022061200/5473f93bb4af9fbe0a8b565b/html5/thumbnails/38.jpg)
Recommendations
• Primary health care intervention package should be expanded and improved– IFA tablets for adolescent girls, PLW– Breastfeeding & complementary feeding– Micronutrient powder for infants & young children– Management of moderate & severe acute
malnutrition
![Page 39: Ahmed 1 the food and nutrition situation in bangladesh](https://reader033.fdocuments.net/reader033/viewer/2022061200/5473f93bb4af9fbe0a8b565b/html5/thumbnails/39.jpg)
Undernutrition hotspots need special attention– Monga-prone areas in the north
– The coastal belt and char areas
– Areas in Chittagong & Sylhet divisions with higher prevalence of child malnutrition
– Rat-infested areas in the Hill Tracts
![Page 40: Ahmed 1 the food and nutrition situation in bangladesh](https://reader033.fdocuments.net/reader033/viewer/2022061200/5473f93bb4af9fbe0a8b565b/html5/thumbnails/40.jpg)
Recommendations
• But the ultimate goal is to prevent/control rapid unplanned urbanization– Create livelihoods in rural Bangladesh– Control population growth drastically– Improve livelihood & living conditions of people who
are already living in urban areas
