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

•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

Page 18: Ahmed 1 the food and nutrition situation in bangladesh

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

Page 19: Ahmed 1 the food and nutrition situation in bangladesh

BBS, World Bank, WFP 2005

•Poverty•Food insecurity•Poor maternal nutrition•Low birth weight•Low rates of EBF•Lack of proper CF•Frequent illnesses

There has been some improvement but much more is required

Evidence-Based Interventions

Bhutta ZA, Ahmed T et al. Lancet 2008

Page 31: Ahmed 1 the food and nutrition situation in bangladesh

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

Coverage is most important !

% of DALYs averted

99% coverage 25% 35% 25%

90 % coverage 22% 32% 23%

70 % coverage 17% 27% 17%

Bhutta ZA, Ahmed T et al. Lancet 2008

Page 35: Ahmed 1 the food and nutrition situation in bangladesh

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

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

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

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

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

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
