Hi Tammam,
You would need a similar comparator (previous SMART surveys) to draw a comparison. In your case, I assume the nutrition screening is not the same as SMART in terms of methodology.
Regarding the SAM/MAM prevalence of SMART, you would need to check the Confidence Interval (C.I.) and design effect to explain the prevalence. If I were a manager of that project, I would not draw conclusions on the impact of your project based on the data you've provided only. To help me do so, I would need a record of programme admission trends and performance indicators over time, and to compare repeated SMART reports. These data, among other indicators, should be analysed within your desired programme impact which was set during the project inception (logical framework).
I am quoting myself below-you might find the comment relevant to your case:
"You can check if there a statistical significance between the prevalence of the two surveys by using the CDC statistical calculator for two surveys. It comes with the SMART training package (managers training), please check the annexes on the SMART methodology website. The difference will be mainly based on the interpretation of the p. value as my colleagues indicated above. C.I. overlap is one quick way to do it as well.
You have to consider other circumstances when you draw comparisons, such as seasonality, sample size, design effect, other nutritional deficiencies, livelihood status or other health interventions in the area, and whether CMAM services have expanded since the last survey or not, or if there was an outbreak of acute watery diarrhoea since the last survey etc. You may wish to talk to health professionals and community members to get insight into your interpretation.
I have worked on SMART surveys and CMAM in Darfur and Yemen, I know sometimes you feel pressured to find and report progress in the nutrition status of children within your programme areas to satisfy donors. SMART reports when they are not consistent over time they may cause confusion and frustration. However, when you look at your programme indicators, admission trends and performance, you should know if your intervention is working or if it needs a bit of improvement. In all cases, interpret your SMART findings based on your context, you and your field team could tell if the nutrition situation is getting worse."
