Measuring the prevalence of hunger in the Philippines directly from food consumption data
2006
Arcilla, R.G.
Two methodologies for measuring prevalence of hunger, defined as the consumption of a diet inadequate to sustain good health and normal activity, growth and development, were developed using the 2003 Food Consumption Survey. The first methodology compared per capita energy consumption using the divisor total consumption unit TCU with per capita hunger threshold. The second methodology compared household's total dietary energy consumption with household hunger threshold. Prevalence of hunger was computed using the design-based combined ratio estimator r sub g. It is a ratio of two counts: total number of hungry households (persons) and total number of households (persons). Estimates were then compared with estimates obtained using the National Statistical Coordination Board (NSCB) and Food and Nutrition Research Institute (FNRI) methodologies on the basis of 1) the properties of the estimates, 2) the strength of association, and 3) the percentage of correct classification, sensitivity, specificity and predictive value. Results showed that the second methodology gave estimates that were accurate, precise and reliable. Regional rankings provided by it had a very strong association with the rankings provided by the FNRI methodology. It likewise had higher percentage of correct classification, sensitivity, specificity, and predictive value. Thus, it is highly recommended for measuring hunger prevalence in the country.
