Visualizing some of the indicators…
Assessment and analysis:“Before conducting an anthropometric survey, information on the underlying causes of malnutrition is analysed and reported, highlighting the nature and severity of the problems, and those groups with the greatest nutritional and support needs.”
“The opinions of the community and other stakeholders on the causes of malnutrition are considered”
“International anthropometric survey guidelines, and national guidelines consistent with these, are adhered to for determining the type, degree and extent of malnutrition”
( please see page 115 of the 2004 Edition)
41
General nutritional support standard 1: all groups
Some indicators:
• There is access to a range of foods -staple (cereal or tuber), pulses (or animal products) and fat sources – that meet nutritional requirements.
• There is access to vitamin A, C and iron-rich or fortified foods or appropriate supplements
• There is access to iodized salt for the majority (>90%) of households
• No cases of scurvy, pellagra, beri-beri or riboflavin deficiency
( please see pages 137 & 138 of the 2004 Edition)
43
General nutrition support standard 2: at-risk groups
Some indicators:
• Infants under 6 months are exclusively breastfed or, in exceptional circumstances, have access to an adequate amount of an appropriate breast milk substitute
• Pregnant and breastfeeding women have access to additional nutrients and support
• Community based systems are in place to ensure appropriate care of vulnerable individuals
( please see pages 140 & 141 of the 2004 Edition)
44
The treatment of moderate malnutrition at supplementary feeding centres
A child suffering from malnutrition is given a food ration of 700 - 1,300 calories, in the form of a cereal broth and vegetarian foodstuffs enriched with sugar and oil, well as mineral salts and vitamins, to supplement the family diet.
45
Correction of malnutrition standard 2: severe malnutrition
Some indicators:
• Proportion of exits from a therapeutic feeding programme who have died is < 10%, recovered is > 75%, and defaulted is <15%
• proportion of exits from therapeutic feeding programme who have died is < 10%,defaulted < 15%
• Coverage is > 50% in rural areas, > 75% in urban areas and > 90% in camp situations
• there is a mean weight gain of 8 kg per person per day
• Discharge criteria include non-anthropometric indices such as: good appetite; no diarrhea, fever, parasitic infestation or other untreated illness
• Nutrition worker to patient ratio is at least 1:10

47
Correction of malnutrition standard 3: micronutrient malnutrition
Some indicators:• all clinical cases of deficiency diseases are treated
according to WHO micronutrient supplementation protocols
• Procedures are established to respond efficiently to micronutrient deficiencies to which the population may be at risk
• Health staff are trained in how to identify and treat micronutrient deficiencies to which the population is most at risk
49
Pellagra
Pellagra is caused by Niacin (vitamin B3) deficiency. The condition can be fatal. Good sources of Niacin include groundnuts, fish, meat and pulses.
Pellagra is sometimes called the described by the ”3 D" disease: Dermatitis, Diarrhoea, and finally Dementia. In extreme cases a fourth can occur - Death
The disease takes 2-3 months to fully develop symptoms.

1 Assessment and Analysis
2 General Nutritional Support to the Population
3 Nutritional Support to Those Suffering From Malnutrition
SUMMARY: The 3 Main areas of the Sphere Standards relating to nutrition are critical - particularly in emergency nutrition programmes.
1 Understand (common standards)
2 Provide enough food for everyone to remain healthy
3 If that fails, implement programmes to treat the malnourished
