Malnutrition, Illnesses, and Infectious
Diseases
Assessing nutritional status with Mid-Upper Arm Circumference (MUAC) is a
relatively easy and cheap way to rapidly screen/assess for acute malnutrition
and a good predictor of immediate risk of death. A volunteer or health extension worker can easily use MUAC in the community and it has been proven
to increase the routine assessment and nutritional categorization of clients.*

integrate nutrition into HIV services—can be scaled up to
integrate nutrition into clinical and community health services and thus, rapidly expand access to nutrition services.
Screening a child’s growth and nutritional status60 and advising parents based on the results should be part of routine
primary health care rather than an isolated activity. Similarly, treatment for childhood illnesses such as pneumonia or
diarrhea should include not only the appropriate antibiotics
but also the appropriate nutritional assessment counseling,
education, and support to help the child recover quickly and
avoid new infections. NACS helps detect and treat malnutrition and supports prevention practices such as optimal
infant feeding and correction of micronutrient deficiencies.
The NACS approach also provides specialized food—
therapeutic foods (for SAM) and supplementary foods (for
MAM). These are nutritionally dense, fortified food products
that treat acute malnutrition and are prescribed as medicine.
Now with the availability of lipid-based ready-to-use therapeutic foods such as the peanut butter-based Plumpy’nut,
which do not require preparation at home and are less susceptible to bacterial contamination than milk-based foods,
children can often be treated at home. This can reduce expenses, ease overcrowding in hospitals, and lessen the strain
on mothers, who must often forego income and leave their
other children unattended to stay with a hospitalized child.61,
62 Additionally, prescribing lipid-based therapeutic foods in
health facilities has been proven to dramatically improve nutritional status and quality of life for patients.63
10 Briefing Paper, February 2012
A healthy immune system protects a person from the majority of infectious diseases, but malnutrition weakens the
immune system. Undernutrition increases both susceptibility to and severity of common illnesses and infectious diseases. Infectious diseases—particularly diarrhea, malaria, and
respiratory illness—also contribute to stunting of children
under two. Complications of seemingly minor illnesses are
more common. Since malnutrition often affects the way infections manifest themselves—for example, fast breathing is
a common symptom of pneumonia, but malnourished children can have pneumonia without fast breathing64—health
workers may need specialized training to provide the correct
treatments.
Many different types of infections (e.g., bacterial, viral, intestinal) make the body less able to absorb nutrients. Studies
have shown that children with diarrhea can absorb as much
as 40 percent less of the protein they consume than healthy
children.65 Poor absorption leads to malnutrition, which in
turn increases a child’s susceptibility to infection.66, 67, 68, 69,
70, 71 This vicious cycle generally cannot be broken through
diet alone; medical treatment of the infection is also needed.
In addition, more and more research is showing that even
if a child survives very early malnutrition, \
