Malnutrition:
Undernutrition
“With diseases related to malnutrition on the rise, the challenge
is not only to ensure food security, but also to address the
nutritional quality of the food being consumed and its impact on
health.” - Dr Frenck G20 2012,
http://www.who.int/pmnch/media/press_materials/pr/2012/201205_g20_watch/en/index4.html
Malnutrition terms
Adequate food is at the basis of an active and healthy life. Yet, in
spite of significant improvements, millions of people today are
malnourished.
Malnutrition: An abnormal physiological condition caused by
inadequate, unbalanced or excessive consumption of macronutrients
and/or micronutrients. Malnutrition includes undernutrition and
overnutrition as well as micronutrient deficiencies.
Minimum dietary energy requirement (MDER): amount of energy
needed for light activity and a minimum acceptable weight for attained
height.
Body Mass Index (BMI) relates weight to height and is used to
evaluate thinness and obesity.

Malnutrition terms
Protein-energy malnutrition: BMI and shortness are indicators. A
broad (older) term from the 1970s when protein deficiency was felt to
be the primary driver behind malnutrition. Replaced by the more
general term ‘acute malnutrition’ which includes macronutrient
imbalance/insuffiency as well as micronutrient deficiency.
Micronutrient deficiency: “hidden hunger”, a lack of one or more
essential vitamins and minerals, such as Vitamin A, iron, iodine or zinc.
Indicator iron-deficiency anaemia low haemoglobin in blood.
Micronutrient powders (MNP) are used to prevent micronutrient
deficiencies; for example, on a large-scale basis in Bangladesh.
Undernutrition
Poor health, growth and development outcomes can result from hunger and poor
nutrition.
Under nutrition is “the outcome of undernourishment, and/or poor absorption and/or
poor biological use of nutrients consumed as a result of repeated infectious disease. It
includes being underweight for one’s age, too short for one’s age (stunted), dangerously
thin for one’s height (wasted) and deficient in vitamins and minerals (micronutrient
malnutrition).(FAO definition http://www.fao.org/hunger/en/)
Under nutrition includes being:
• Underweight: a child has low weight for age. Composite measure includes chronic
and acute malnutrition.
• Stunting: child short for their age as a result of chronic under nutrition during the
most critical periods of growth and development in early life.
• Wasting: child’s weight is too low for their height as a result of acute under nutrition,
can vary with the seasons. Reflects loss of muscle tissue and fat.
• Kwashiorkor: sudden onset swelling of the feet, hands and face. Cause unknown,
but occurs typically in children 2-3 years old once they are weaned from breast milk
and can be cured by feeding a specially fortified milk. Form of severe malnutrition.
Undernourishment
Famine
Undernourishment or chronic hunger: A state, lasting for at
least one year, of inability to acquire enough food, defined as a
level of food intake insuffiecient to meet dietary energy
requirements. For the purposes of this presentation, hunger was
defined as being synonymous with chronic undernourishment.
Famine is the state in which significant proportion (at least 20%)
of a defined population lacks access to food in sufficient quantity
and quality, such that epidemics of infectious disease become
more frequent, acute malnutrition rates in children under 5 are
above 30% and death rates rise. In famine conditions, the most
vulnerable members of the population - the very young, the
elderly and those with chronic illness – are at higher risk of
death.
Starvation
Starvation occurs when the individual’ nutrient intake drops
below what is needed to maintain body mass and the body
begins to consume muscle and other lean tissues in order to
supply nutrients to maintain metabolic function.
In an otherwise well adult who continues to drink water but
ceases all nutrient intake, this process of starvation leads to
death in about 2 months.
The process of starvation affects all the body’s organ systems,
but the most visible signs are weakness, apathy and muscle
wasting.
Hunger IQ and FAQs
Action for students:
1. With a partner test your Hunger IQ: http://www.wfp.org/hunger/faqs and
read Hunger Frequently asked questions (FAQs) including the overview,
record what is hunger, who are the hungry, what causes hunger, what is
malnutrition?
2. Extract the salient information from each of the documents and
individually record the information so you can readily refer to it.
3. Can you explain why solving hunger is regarded as a ‘best buy’ in
today's tough economy?
4. Use the data from Who are the hungry?
– Draw a bar chart showing how the 870 million hungry people in the world are
distributed.
– Draw a pie chart which shows the proportion of hungry people living in rural areas.
– Draw another pie chart showing the proportion of hungry people from small holding
farming communities, those from landless families dependent on farming and the
proportion dependent on herding, fishing or forest resources.
Hunger
case studies
“Every man, woman and child has the inalienable right to be free from hunger.”
- First World Food Conference Declaration, Rome, 1974
Action for students:
1.Look through Hunger in the news
http://www.wfp.org/news/hunger-in-the-news
2.Make brief notes on the current hunger crises and debates around the globe paying
particular attention to the case studies used in this unit:
- The Sahel (Sub-Saharan Africa )
- Bangladesh, India (South Asia)
- Kenya
- The UK
- The USA
3.What is in the news about these case studies, malnutrition and life on the margins? Add
helpful information to your notes.
World economic growth
and undernourishment
Agriculture plays an essential role in the world economy. Beyond food
production, it is as an engine of economic growth key to growth in rural settings
and poverty reduction in transition countries. It generally accounts for half of
GDP in developing countries; its share in the economy tends to decline with
development. Investments in agriculture have a poverty-reduction impact larger
than any other sector.

Rise in
hungry people
Number of hungry people, 1969-2010
Since 1995-97 the number of
hungry people has risen.
Even at times of economic
growth and low food prices,
the number of hungry has not
fallen below around 800
million over the past 40
years.

Factors in
rise of hungry people
Factors:
1. Governments and international agencies have neglected agriculture
and the synergy between agriculture and social protection relevant
to very poor people; for every five people suffering from hunger, three
rely on farming. Women and small holder farmers most affected. Food
reserves have also shrunk.
2. Current worldwide economic crisis and financial, trade and policy
issues;
3. Energy and climate issues;
4. Devastating impact of food price hikes, a large upward movement in
price in a short time, on people existing on only a few dollars a day.
5. Speculation and concentration of agribusiness* and retail among
very few players.
* Agribusiness: the manufacture and distribution of farm supplies,; farm production operations, storage,
processing and distribution of farm commodities and products most often by corporations.

How malnutrition kills
•
The commonest form of malnutrition called marasmus results in an
affected child being severely wasted, with no fat and very little muscle
tissue left on his or her body. The internal organs, including the heart and
the blood, are also weakened. The child is left with no reserves to fight
infection, and any illness that comes along is likely to be fatal. The
commonest causes of death during a famine are in fact infectious diseases,
rather than starvation per se. Chief among these are pneumonia,
diarrhoea, and measles.
–
•
•
UNICEF on Marasmus http://www.unicef.org/nutrition/training/2.3/4.html
The other form of malnutrition, called kwashiorkor, in which the child's
body is swollen, likewise kills by lowering resistance to infection. However,
kwashiorkor can also be fatal in its own right, because of the disturbed
levels of salts and minerals (electrolyte imbalances) that accompany it.
In a therapeutic feeding centre, where only severely malnourished children
are cared for, many deaths tend to occur at night. This is because these
children are especially prone to low blood sugar (hypoglycaemia) and low
body temperature (hypothermia). (MSF US website)

Determinants of
child nutrition and development
Immediate determinants include:
• Adequate food and nutrition intake
• Parenting, caretaking and feeding practices
• Low burden of infectious diseases
Underlying determinants include:
• Food and nutrition security
• Adequate resources at the community, household and maternal
(mother’s) level
• Access to health care provision
• Safe and hygienic environment

Wasting and stunting
When a population is short this points to nutritional deprivation or disease in
childhood.

A STUNTED IN CHILD
• has greater propensity for developing obesity and
chronic diseases as an adult, fuelling obesity epidemic in low
and medium income countries.
• has lower chances of survival and
less optimal health and growth.
• is more likely to have been born to a mother with poor nutrition
and health status, which perpetuates
vicious cycle of under nutrition and poverty.
International health organisations are starting to shift their focus from
underweight prevalence (inadequate weight for age) to prevention of
stunting (inadequate length / height for age).

Stunting prevalence by region
Globally, about 1 in 5 (26% in 2011) children are stunted of whom 80% live in 40
countries. Undernutrition affects poor children most, but rates are high enough to deserve
attention even among the better-off children in developing countries.

Childhood malnutrition:
causes, campaign and Sahel (1)
The mother’s status (is she disadvantaged?) is likely to affect
the child’s food intake and health status – both proximate determinants
of the child’s nutritional status.
Causes of malnutrition include:
• poverty,
• quality of environmental conditions (poor housing conditions,
inadequate water, hygiene practices and sanitation),
• illiteracy,
• unemployment,
• social problems
• poor awareness about mal/nutrition
• poor access or quality of health services.

Girls and women
• The distribution of malnutrition is highly gendered, girls and
women make up more than 70% of the world’s hungry (UN).
• Girls and women produce more than 55% of the world’s food
supply (UN). They endure lower salaries, fewer promotions, less
secure employment, unreasonably long hours whilst continuing
with traditional household responsibilities.
• They represent 41% of farmers around the world; own only 2% of
the land (Rural Poverty Portal)
• Women in Africa receive less than 10% of all credit going to small
farmers, and only 1% of the total credit going to the agricultural
sector (Rural Poverty Portal)

Women’s
empowerment (1)
Women’s health and nutrition, equality
and empowerment are worthwhile ends in themselves.
In addition they have many benefits, including:
• Intergenerational benefits
• Poverty reduction
• Economic efficiency
In many settings, greater access to agricultural lands
and economic rights are needed for women to exploit
the synergy between agriculture and social protection.

Women’s
empowerment (2)
“Gender-based inequalities at every point in the value-chain have traditionally
impeded the realization of food and nutritional security.....In most developing
countries women play a key role in the cultivation of food and cash crops as well as
the nutritional care of their children and are therefore critical to food and nutritional
security. Investment in women can lead to tremendous dividends.”
According to the Lancet, evidence supports that women and men allocate food
differently. There are:
• Positive associations between women’s empowerment and improved maternal
and child nutrition.
• Negative associations between disempowerment such as domestic violence and
child nutrition outcomes
• Positive impacts on women’s empowerment of agricultural programmes and
cash transfers

Improving Maternal and Child Nutrition?” http://download.thelancet.com/flatcontentassets/pdfs/nutrition_4.pdf
Women’s inequality
drives the cycle
•
Gender “refers to the socially constructed roles behaviour, activities and
attributes that a particular society considers appropriate for men and
women.” Not inherently given by biology, these vary across cultures.
•
“The distinct roles and behaviour may give rise to gender inequalities, i.e.
differences between men and women that systematically favour one
group. In turn, such inequalities can lead to inequities between men and
women in both health status and access to health care.”
(http://www.who.int/topics/gender/en/)
•
Gender equality “implies a society in which women and men enjoy the same
opportunities, outcomes, rights and obligations in all spheres of life.”
(http://www.unfpa.org/gender/empowerment.htm)
•
Gender equity Process of being fair to men and women alike that leads to
equality.
•
Gender empowerment: “A critical aspect of promoting gender equality is the
empowerment of women, with a focus on identifying and redressing power
imbalances and giving women more autonomy to manage their own lives.
Women's empowerment is vital to sustainable development and the
realization of human rights for all.”

Malnutrition in
South Asia
“Among all regions, South Asia has the worst record on malnutrition... In
developing countries, on average, 29 per cent of children are underweight; In South
Asia it is 49 per cent. Thirty-three [of] children in developing countries are stunted; but
48 per cent in south Asia are. Ten per cent of children in the developing world are
wasted; the share is 17 per cent in south Asia ... [but] child survival rates in south Asia
[are] so much better than in SSA....the south Asian child usually has better access to
modern medical care, especially antibiotics”

Bangladesh
profile (1)
•
In South Asia, Bangladesh urbanisation (highest rate in South Asia) is
largely driven by rural-urban migration, which gained in momentum
after the country’s independence in 1971. The capital Dhaka has most
dominant role.
•
Half of its population of 163,654,860 (July 2013 est., CIA World
Factbook) live in poverty and about one third in extreme poverty, so
third largest number after China and India. Poor access to food due to
poverty.
•
Between 1990 and 2010 poverty rates declined substantially with per
capita GDP doubling and economic growth appearing to have reached
the poor; agricultural growth averaged 3.3% a year thanks to great gains
in rice yields (FAO 2012).

profile (2)
•
Most densely populated country in the world, 28.4% of total population
is urban (2011). Overcrowding, especially intense in urban areas, makes
environmental hygienic conditions worse, which leads to greater disease
affecting absorption of nutrients. The socio-economic status of rural-urban
migrants is moderately lower than their urban native counterparts.
•
Women in South Asia have the worst educational indicators relative to
men with lowest adult literacy rates for women as a percentage of men
(63%)*
•
Bangladesh has seen dramatic advances in child survival thanks to
– economic, economic and political empowerment of women; and
– higher participation of girls in formal education with literacy rates 38% in
1991 increasing to 77% in 2009

“During pregnancy, they eat the same food. Whatever they are having now, they have the same then.
Who will give them extra food? That’s why their children are weak and suffer from malnutrition; for
which they do not do well in education like the children of the rich class. Who will get this fact?”

•
Share of government spending on health about double that of India and Pakistan, its large

•
Twenty-five million face hunger. Hunger distribution is highly gendered with nearly one third of
women undernourished (Ahmed, Mahfuz, Ireen et al 2012)
•
Second highest child malnutrition rates in the world with 48%, which is linked to low status
of women in Bangladeshi society (circumscribed autonomy/agency). Husband and boys can be
prioritised in food allocation. Mothers and daughters can have inadequate or low quality food and
work requirements, leading to low health status.
•
Malnutrition, it is estimated, costs US$ 1 billion a year in lost economic productivity.
•
An estimated 50% reduction in undernourishment has been achieved (SUN 2011) Consumption of
nutritious food appears to be on the increase.

THE DOUBLE BURDEN OF
MALNUTRITION AND
NUTRITION TRANSITION
“Malnutrition, both under and over, can no longer be
addressed without considering global food
insecurity, socioeconomic disparity, both globally
and nationally, and global cultural, social and
epidemiological transitions.”
- Darnton-Hill and ET Coyne “Feast and famine: socioeconomic disparities in global nutrition and health”

Double burden of
malnutrition (1)
Double burden of malnutrition: Persistence of under nutrition, especially
among children, along with rapidly increasing overweight, obesity and dietand life-style related chronic diseases especially among the poor. In
China, for example, there has been a significant rural-urban difference in
obesity prevalence which offset marked reductions in underweight
prevalence.
These forms of malnutrition usually result from uneven access to food and
unbalanced diets. Both under- and over-nutrition are problems of poverty
and are bound to become even more closely interwoven. Immediate and
root causes of malnutrition are multidimensional and complex.
Double burden of
malnutrition (2)
In countries where famine and under nutrition were traditionally the
main issue, the reverse now is the case: over nutrition is increasing,
especially in India and China, countries recently more affluent.
In developing countries, rapid urbanisation is linked to diets with
more fats, animal source foods and processed products and lower
activity levels resulting in higher levels of obesity.

Action for students: Write a few paragraphs for your folder explaining
what is meant by the phrase “the double burden of malnutrition.”
contents
Nutritional adequacy
•
•
•
•
Energy – provided in the form of protein, carbohydrates and fats.
Sometimes referred to as macro-nutrients.
Micronutrients – vitamins and minerals essential to all metabolic
processes in the body. Fruits and vegetables are rich in micronutrients,
as are many animal sourced foods. Liver is an excellent source of iron,
B vitamins and Vitamin A.
Animal sourced food – meat, fish, eggs, dairy. These foods provide
complete protein and many micronutrients in addition. For example,
dairy foods provide complete protein, an excellent source of calcium,
zinc and essential fats.
Tubers and cereal – the least expensive source of energy,
predominately carbohydrates. Also provide some protein and often rich
in B vitamins. However, protein is usually not complete and these foods
must be paired with beans or lentils to provide all the essential aminoacids (protein-building blocks).
Hunger and obesity both forms of malnutrition

5.
Discuss in groups of four why hunger and obesity
are two sides of the same coin, bearing in mind
socio-economic, political and environmental factors.
Poorest are
most vulnerable to malnutrition
Triad: Poverty – Dietary Quality / Adequacy – Health
In MEDC, poverty can be associated with poorer health and
shortened life expectancy due to obesity because calories are cheap
and micronutrients are expensive.
In LEDC, it can manifest as wasted/stunted children who do not get
enough of the right kinds of foods at crucial moments in their life
when assailed by many infections. Adult obesity is one of the risks in
populations with many undernourished young children as well as
higher mortality rates at all phases of the life cycle.
Hunger and obesity
The number of hungry people and obese people are both growing, worldwide.
Source: FAO and WHO study http://www.farmingfirst.org/green-economy/
Hunger and obesity
afflict poorest populations most (1)
• Root cause of chronic hunger: poverty and lack
of income generation. These also can limit
access to basic health and sanitation services
and decent housing.
• Malnutrition and food insecurity are interrelated
with poverty.
• Social disparities drive both hunger and obesity.
• Tremendous issues around affordability of food,
percentage of income spent on food.

Globalisation of
hunger and obesity
Globalisation and technical innovation have reduced global inequality, but
inequality within countries has widened. The twin forces expose the food system
to novel economic and political pressures.

Action for students:
1. Define globalisation and take special note of trends and their
relevance to obesity and hunger around the world
http://www.newworldencyclopedia.org/entryGlobalization
2. In pairs, watch the Ted Talk video and explain Why “Obesity +
Hunger = 1 Global Issue”. What does globalization of obesity and
hunger mean? How does obesity in the US relate to Africa?
2. Work with a partner and discuss and record the conclusions that can
be drawn from the TED talk.

Public health
issue
Obesity is an issue that is as complicated as undernutrition and it
is far more complex than personal lifestyle choices.
• Double burden countries. India is the best example. High
prevalence of low-birth weight and childhood undernutrition and
rapidly increasing prevalence of adult obesity
• Mexico: now the most obese country in the world. Excessive
consumption of sugar-sweetened beverages, in large part driven by
a long history of water-borne illness in the water supply (e.g., poor
sanitation, contaminated drinking water)
• Food policies: the US government with a forty-year history of
subsidising corn and soy bean farmers – resulting in a large source
of cheap calories , but lead to high calorie, cheap food that coerce
the poorer quintiles of the population into consuming less nutritious
food that promotes obesity.

Obesity:
Physical factors
Apart from social disparities and being at the bottom of the
income distribution, physical factors cause obesity. These are
influenced by the food and physical activity environment in
which people live.

Health
consequences
of obesity
In many countries around the
world, being obese is now the
biggest driver of sickness,
because it raises the risk of,
for example, diabetes, heart
disease, stroke and some
cancers. It is also linked to
the increased incidence of
osteo-athritis of the hip and
knee (major cause of hip and
knee replacements)

http://www.healtheo360.com/blog/729/obesity-a-ticking-time-bomb/; The Economist December 15th 2012;
Impact of obesity
• Individuals bear the bulk of the burden, but in many countries the
state covers some or most of the associated and growing healthcare
costs.
• The prognosis of those who do fall ill depends on where they live
and whether they have access to health care. This can be a major
issue for the poor living in the US and India, for example, where
there is very high quality health care for those who can afford it.
• The social consequences go beyond increased health costs and
include:
–
National security concerns. In the United States, where health care is privatised
for approximately half of the population, obesity is seen as a national security
issue because so many military recruits are unfit (overweight). Similarly in
China, childhood obesity is becoming a major concern, resulting from increased
wealth (better and higher caloric diets) at the intersection of the one-child policy.
– Economic concerns: lost work days due to illness ultimately impacts productivity.
Obesity and social
inequality in the UK
•
•
Obesity prevalence for adult women increases overall with greater levels of
deprivation regardless of indicator used, whereas only occupation-based and
qualification-based measures show differences in obesity rates by levels of
deprivation for adult men.
Highest level of educational attainment can be used as a measure of socioeconomic
status. Obesity prevalence goes down as levels of educational attainment go up for
both women and men.
Action for students: In
pairs, explain why
malnutrition and disease
work in a deadly cycle
and are driven by
inequality and note
down your agreed
answers in your folder.

Since 1980: significant increases in global obesity** rates, the rate has
nearly doubled
Rises in obesity-related chronic diseases poses threat to individuals,
health care systems and economies (e.g., cardiovascular disease diabetes
type 2, musculoskeletal disorders — especially osteoarthritis, some cancers
(endometrial, breast, and colon).
Since 1990: rise in childhood obesity.
Obesity has now reached epidemic*** proportions globally. Most prevalent
in high-income countries, the obesity epidemic is also spreading to low- and
middle-income countries as countries move up the income scale.
Sixty-five per cent of the world's population live in countries where
overweight and obesity kills more people than underweight.
Obesity: Body mass index (BMI) of 30 or higher. Body mass index is defined as the individual's body
mass divided by the square of their height
Overweight: 25 BMI or higher.
** Rate “A measure of the intensity of the occurrence of an event. For example, the mortality rate equals the
number
who die in one year divided by the number at risk of dying. Rate—A measure of the intensity of the
occurrence of
an event.“(http://www.idph.state.ia.us/hpcdp/common/pdf/10_glossary.pdf)

• Developmental transition: better food and nutritional status;
urbanisation and globalisation as countries become more
developed. Urbanisation and meat consumption rising hand in hand
• Nutrition transition: shift to food with high energy density
especially fat “stone age appetites meeting capitalist abundance”
• Life style changes especially less physical activity
• Social disparities in obesity are unabated. Obesity shifting
disproportionately to poor.
• Paradox: persisting underweight along with rising obesity within the
same country, sometimes household.

There are worryingly high rates of inactivity. “Since the beginning of the industrial revolution,

Nutrition
transition
Convergence of diets and lifestyles globally:
•
More globalised food tastes such as westernised habits of meat eating, more dairy
which takes more energy to produce and drives future grain consumption.
– Media encourages the food transition from traditional diets of grains and
vegetables to often high protein and fats and sugars, westernised dietary habits and
lower physical activity levels. Globalisation can mean that there is a switch from
associating being obese with being rich to with being poor.
– With rising income rising middle classes in transition economies such as China are
changing their food habits (China more quickly than India for various reasons)
•
More choices and less active life style in urban areas
•
Mechanisation of farm activity, switch from subsistence farming to high yielding cash crop
also imports bad eating habits to rural areas. Food transition drives obesity and heart
disease health risks and changes in the social and physical environment of production
areas.
•
The shift to foods that are far more resource-intensive to produce such as meat puts
pressure on scarce resources.

Consumption culture
Many consider obesity a personal decision or weakness, but
actually a culture of consumption with much broader forces
must be at work given the growing scale of the problem around
the world.
Many answers to deal with obesity have to do with culture and the
food system and are not medical or personal, but the chronic
health problems created in part by the food system tend to be
medicalised by healthcare systems (hooking us up to machines
and onto medicines).
