ASSESSMENT AND ANALYSIS
what is data? what is its relation to reality?
levels and units of analysis
types of variables
determining -- causal, interactive, confounding
2. Planning framework:
questions to address
(and dummy tables)
For programme planning …
You need to decide:
Coverage: how many people?
Content: what activities (components)?
Specify … keep going till you answer them … refer back to them when you get lost
(tables, models, graphics)
Work up dataset
Research questions on malnutrition (examples):
How serious/extensive is it? (Compare to norms)
Is it worse in some places/for some populations? (Compare between groups at one time)
Is it getting better or worse, for whom? (Compare between times, for groups: norm 0.5 – 1 ppt/yr)
What is cause of current situation, or changes? (Analyze associations; includes evaluation)
You could also ask: what problems are we trying to solve, and what resources do we have … this would come in at question 1, but then continue to ask how the resources address the problems ...
E.G of dummy table
E.g. of cut-points: 10% warning, 20% emergency
Example of dummy table: compare districts A and B
Don’t forget precise title!
Prevalences of wasting and stunting in children < 110 cms in Northern province, January 2007
3.Is malnutrition getting better or worse, for whom?
Example of dummy table
Prevalences of wasting in children 6-59 months in January and July 2007 in Northern province
Prevalences of underweight children (6-59 mo) in 2001 (May-July) and 2005 (June-Nov)
Sources: DHS, 2001; MICS, 2005
4A.What are possible causes of the current levels of malnutrition?
Prevalence of underweight in children (6-59 mo) by food security and district, controlling for education level
4B.What are possible causes of changes in malnutrition?
Changes in prevalences of malnutrition Jan – July 2007 in children (6-59 months) with receipt of food aid, for food insecure and secure households.
