 Household food security
 Protecting consumers through improved
food quality and safety.
 Preventing and managing infectious
diseases
 Promoting breastfeeding
 Promoting appropriate diets and healthy
lifestyles

 It uses standardized technique
 It is suitable for large sample sizes,
such as representative population

10.  National surveys
which are periodically conducted at
national level (BDHS-2007, NNP 2004)
 Small-scale surveys
which are carried out at local level to
gather nutrition information within the
shortest time possible.

11. Biochemical testing contribute to diagnosing
micronutrient deficiencies.
 The most common deficiencies are:
• Iron
• vitamin A, and
• Iodine
 During emergencies:
scurvy
Beri-Beri (vitamin B 1 deficiency)
pellagra (vitamin B 3 deficiency).

12. Example : National Nutritional survey
2004
 Haemoglobin level among adolescent
girls
 Table salt iodine level
 Urinary iodine excretion
 Prevalence of stool parasite

13. Information on food intake may help
 to better understand the causes of
malnutrition and
 can also be used as a proxy for nutritional
outcome.

14. Food intake or consumption surveys assess
 the types and amounts of food eaten. This can be
represented in terms of daily energy and nutrient
intake per person.
 May involve weighing amounts of food eaten or using
dietary recall.
Difficulties:
 labour-intensive
 time consuming and costly.
 Dietary recall are more dependent on memory.
 The analysis of food intake surveys requires high level
of skills
 the use of specific software
 availability of a food composition table.

15.  Advantages:
 provide invaluable information on
quantities, diet quality and
 on whether energy and nutrient intake
are being met.
 This type of assessment is undertaken
in stable contexts where more
information is needed about dietary
causes of malnutrition.

16.  Dietary diversity (DD) scores is a proxy of nutritional
quality of the diet.
 The DD scores consists of a simple count of the
number of food groups consumed by an individual or a
household over a given period of time.
 The assumption is that the higher the score, the better
the quality of the diet.
 Assessing DD is useful to evaluate the impact of a
wide range of programmes on dietary quality.
 Examples are livelihoods and crop
diversification, nutrition education, school and
homestead gardens.

17.  These assessments may be carried out
in stable situations where there is a
known problem of lack of dietary
diversity and where efforts to improve
agricultural diversification in order to
improve diet have been ongoing for
many years.
 The DD assessment can also be used
in emergency contexts, where shock
can adversely impact the quality of the
diet.

18. Carried out at
 food distribution sites
 camp situations, e.g. among refugees
 in order to ensure that food distribution
systems are operating optimally
 to help identify any risk of nutrition problems,
especially micronutrient deficiency diseases.

19.  Where camp populations are dependent on
long-term food aid, FBM is critical, especially
where the ration diversity is limited and
where there is an absence of micronutrient
rich foods in the ration, e.g. fortified Corn Soy
Blend.
 Computer programmes to calculate
micronutrient content of food rations are
available.
