  1. Assessment of MortalityGroup II

  2. General remarks • Mortality is an important indicator to be included in nutrition surveys. • Mortality estimates often reported without CIs. • Mortality estimate determination basically based on absolute no. of deaths. • Variation in mortality questionnaires. • Collection of mortality data require a lot of other qualitative attributes for data quality/accuracy. • Appropriateness of determination of mortality in small scale surveys.

  3. Issues arising • Concerns on adequate sample size..30x30 methodologies commonly used hence 900 units. However, 900 not good enough. • Mortality data most appropriate in emergency situations as opposed to stable and/or non-emergencies. • Why the interest in Mortality in non-emergency situations? • How have the results or data been used? • Is there any evidence of how mortality data from nutrition surveys has been used to determine what intervention to undertake? • If no,..Is mortality data collection really necessary in nutrition surveys? • All-age vs u5 mortaltiy.

  4. Resolutions • Different methodologies used for mortality..Recall, birth history… • Recall method commonly used in small scale surveys. Got limitations in reliability. Recall time often not long enough to eliminate/spread errors. Could result into over or under estimates. • Not much correlation expected btn wasting & mortality • Overlapping CIs possible cause of unreliability of data.

  5. Resolutions cont’d • Mortality indicators rarely reported without CIs yet if well reviewed could otherwise prove as much or more importance than GAM rates. • Mortality data in nutrtition surveys help to better analyse, interprete and understand othe nutrition indicators. • Sample size dependent on whether it’s done using; 1. number or 2. time. • Experience has shown that different limits/standard aler points should vary within a given context, therefore interpretation of results should be done within a given context.

  6. Conclusion • In principle mortality relevance is agreed, but it remains unclear in practice. • More research required on the practical use of mortality info in from nutrition surveys. • Given the issues related accuracy and reliability of mortality data/results, further insight required in the following: Recall period, use of CIs & sample size. • Need to get a sense of how many children in age group and actual timing of deaths in hh. • Interpretation of results also require further revuew. It could the the possible reason why mortality data is not commonly used..
