Nutrition Survey Results Database
Nutrition Survey Results Database
Information on the NICS Database
The Nutrition Survey Results database presents the outcomes of the nutrition and mortality surveys which have been made available to NICS. All survey reports are checked for methodology and results. Only those surveys which correspond to the criteria mentioned below, following internationally agreed standards 1,2,3,4, are included in the database:
Cluster sampling using a proportional to population size (PPS) sampling, with at least 25 clusters
Systematic or simple random sampling
Exhaustive surveys
Sample size
The required sample size for any given survey depends on the prevalence of malnutrition; therefore, no minimum sample size is defined for inclusion in the database. All surveys are included for which the 95% confidence intervals are sufficiently narrow to give interpretable results.
