Oromiya, Ethiopia
• Total population: 28,067,000, with only 14 percent lives in
urban areas (Ethiopia Demography and Health, 2008).
• Economy:
– Major national income: agriculture
• Coffee (50-60% of total exports)
• Crops (cereal, pulses and oil crops)
– Vulnerable to food shortages due to natural disaster (flooding,
droughts)
• Education level:
– Literacy rate: 36% (2004), male > female, female literacy in rural
only 17%
– Education attainment: 66% of females with no education, with less
than 2% completed primary and secondary leve
• Health worker:
– Ratio of health workers: 3 per 10,000
– Ratio of public health workers: <0.5 per 10,000

Malnutrition
•
•
•
•
Malnutrition is commonly used as an
alternative to under-nutrition but also
refers to over-nutrition.
Malnourished: inadequate calories
and protein for growth and
maintenance or inability to fully utilize
the food due to illness (undernutrition).
Malnourished children are susceptible
to increased risk of infections (diarrhea
and Acute Respiratory Infection)
Anthropometric indicators of nutritional
status by WHO (WHO Child Growth
Standards) :
– Weight-for-age
– Height-for-age
– Weight-for-height

Severe Acute Malnutrition
• Severe acute
malnutrition “wasting”
is defined as very low
weight for height (below
-3 SD of the median
WHO growth
standards)
Indicator
Measure
Severe wasting
Weight-for-height
< -3 SD
Severe wasting
Mid-upper-arm
circumference (MUAC)
< 110 mm

Prevention Strategy
Facility-based treatment (F-100)
• Advantages:
– Basic ingredients components
– WHO recommendation
• Disadvantages:
–
–
–
–
8/04/2015
Longer recovery time
Relatively expensive
Cooking required
Water-based food (bacterial
contamination)
• Challenges:
– The dearth of skilled health
workers and health
infrastructure
– Poor accessibility (physical
and economic) to these
facilities
– Opportunity and travel costs
incurred by the mother (or
caregiver) getting to staying at
the health center with her child
(more spending time)
15
Prevention Strategy
Community-based treatment (RUTFs)
•
•
Advantages:
– Short time recovery
– Relatively cheap
– No cooking required
– Oil-based food (less bacterial
contamination)
– Fewer communicable illnesses
(through hospital transmission
with other patients)
Disadvantages:
– Patent issue
– Imported ingredients
8/04/2015
•
Challenges:
– Importing ingredients are not
available locally (particularly
dry skimmed milk and the
mineral–vitamin mix)
– Requires clinic nearby or
community health workers for
monitoring progress, treating
illnesses, and distributing
RUTF
– Limited evidence on the
efficacy
16
RUTF
• Ready-to-Use Therapeutic Food (RUTF): homebased therapy for severe child malnutrition or
severe wasting
8/04/2015

• RUTF is a lipid rich
spread paste, contains
of a mixture of
ingredients

Study Design
•
•
•
•
Study type: Randomized controlled trial
Research questions: Is RUTF more effective and cost-effective strategy to
treat severe acute malnutrition among under-five children in community-based
level compared to F-100?
Study hypothesis:
– Null hypothesis: RUTF is as effective and cost-effective as F-100 in the
treatment of severe acute malnutrition among under-five children in
community-based level
Study population: all under-five children aged 6-59 months suffering from
severe acute malnutrition, living in East Hararghe zone in Oromiya region (the
highest adjusted proportion of severe wasting)
– Inclusion criteria:
• Presence of severe wasting (WHO criteria: weight-for-height Z-score is
less than -3 SD)
• Ability of parents or guardians to provide informed consent
– Exclusion criteria:
• Presence of chronic diseases and not good appetite

Objectives
• To compare the effectiveness of F-100 and
RUTF as the treatment of severe acute child
malnutrition among under-five children in
community-based level
8/04/2015
21
Sample
• Sample size is calculated by the sampling method of
comparing proportions for two independent samples.
• From the previous study, % mortality rates for the treatment of
RUTF and F-100 are 3.0% and 5.4%, respectively.1
Assuming 5% two-sided significance level and power of 80%,
we get the sample size of 1,096 for each group. So, total
sample for this study is 2,192 children.

Outcomes
• Primary outcomes:
– Rates of growth (% children with weight-forheight Z-scores >-2 SD)
• Secondary outcomes:
– Mortality (% death rate)
– Rates of normal weight-for-age and heightfor-age (Z-scores >-2 SD)
– Cost of treatment
– Length of recovery time (days)
8/04/2015
23
Intervention
• Intervention:
– Standard F-100 (control)
– Standard RUTF
• Sample is randomly assigned to each
intervention (n1 = n2 = 1,096) for 8 weeks
follow-up
• Each children who is assessed for
anthropometry and identified by the health
workers as severe acute malnutrition will be
allocated to the treatment
8/04/2015
24
Case Identification
• Anthropometric screening
for weight-for-height -3
SD (severe acute
malnutrition/wasting) by
the community health
workers
• Children are taken to the
nearest village health
posts to get measured on
weight and height
• Mothers are expected to
have additional transport
cost to the village health
post  incentives

Next steps….
• Disseminate the results in policy brief
paper to encourage the government and
other stakeholders and persuade potential
industry to locally produce RUTF
• Ask for government support in providing
initial budget, raw ingredients and
technical assistance  building advocacy

Limitation and Challenges
• Study limitation:
– Blinding is not applied
– Conducted only in one area
– Measurement bias
• Challenges:
–
–
–
–
–
–
8/04/2015
Limited numbers of health workers and professionals
Inadequate health facilities
Low coverage of media and health information
Poor transportation system due to geographical condition
Limited funding
Legal ramification issue in RUTF patent and license 
long-term development
32
Recommendations
• Community-based therapeutic care  scaled up in both
emergency and non-emergency settings
• Provide appropriate training included in medical, nursing
and primary health-care curricula
• RUTF  widely produced and distributed to decrease
barriers in access, reduce opportunity costs associated
with treatment and encourage compliance by patients
• Provide further study (qualitative) on the response or
perception from local people, government and
community leaders
