Research. Do NOT change current methods unless new methods have been tested. MR method - prior birth history CMR v <5MR other data: 30-35yr children, Mother:child ratio, demographic profile etc. Anthro - calculation from mean/ GIS other data: MUAC vs anthro (mort risk). CMR - why?.

Research
  • Do NOT change current methods unless new methods have been tested.
  • MR method - prior birth history
  • CMR v <5MR
  • other data: 30-35yr children, Mother:child ratio, demographic profile etc.
  • Anthro - calculation from mean/ GIS
  • other data: MUAC vs anthro (mort risk)
cmr why
CMR - why?
  • Most basic public health indicator - should have some idea of CMR in all populations
  • Need to assess overall severity of population stress
  • to inform resource allocation
  • documentation/ advocacy
  • calibration of surveillance data/ triangulation
  • urgency of intervention
cmr when
CMR - When?
  • Best obtained with surveillance methods
  • use survey if no reliable data from other sources
  • Co-ordination of timing with other agencies
  • At same time as anthro survey
  • seasonality/ peak
cmr how
CMR - How?
  • By surveillance methods where possible (with calibration)
  • No evidence based basis for choice of a particular method at the moment
  • Current household method most often used - other methods should be chosen where they are thought to have advantages
  • need to assess prior birth history method as it appears to be the most promising method
  • 3 month recall where possible.
cmr who
CMR - Who?
  • Scale - each agency has different purpose for survey. National to micro scale.
  • To large a scale averages out pockets: to small a scale misses pockets and is not generalisable- difficult to use data to inform where there is a problem.
  • Commend areas based upon characteristic likely to be important determinant - Agroeconomic zones, tribal/ethnic areas, etc. and not necessarily administrative districts
  • CANNOT in general be used to decide where to set up a program - this comes from other information
anthro why
Anthro - why?
  • Need to assess overall severity of nutritional stress in population.
  • to inform resource allocation
  • documentation/ advocacy
  • urgency of intervention
anthro when
Anthro - When?
  • Need to design feeding programs
  • when surveillance /program data shows that there is a problem
  • when program “coverage” likely to have changed.
  • Seasonality/ peak and trough
  • Co-ordination of timing with other agencies
anthro how
Anthro - How?
  • Systematic random sample where feasible otherwise cluster sampling
  • 30x30 clusters unless data to inform assumptions and expertise available
  • use systematic random or random for cluster choice if feasible and convenient. Otherwise start - chose person from crowd and go to his/her house to start; then EPI-n with bottle spin after each house.
  • Take ALL children in house
  • use houses with no children for CMR/demographic other data collection.
anthro who
Anthro - Who?
  • As with Mortality rates - each agency has different purpose for survey. National to micro scale.
  • To large a scale averages out pockets: to small a scale misses pockets and is not generalisable- difficult to use data to inform where there is a problem.
  • Commend areas based upon characteristic likely to be important determinant - Agroeconomic zones, tribal/ethnic areas, etc. and not necessarily administrative districts
  • CANNOT in general be used to decide where to set up a program - this comes from other information
anthro who 2
Anthro - Who? 2
  • From program data - e.g. map admissions to TFC - new arrivals - anecdotal information.
  • Assess with anthro survey (area often security delimited)
  • secure areas likely to be best
