Wasting is one of the indicators of malnutrition known to contribute to the deaths occurring from childhood malnutrition. It is the measure of body mass in relation to body length used to explain recent nutritional status. Wasting is defined as the percentage of children under 5 years old whose weight for height is below -2 standard deviation (moderate and severe wasting) and -3 standard deviation (severe wasting) from the median. Moderate or severe wasting in the Philippines was estimated at 7.1. percent in 2015 (NNS, 2015). This translates to about 800,000 children suffering from either moderate or severe wasting. Among its neighboring ASEAN countries, only the Philippines recorded a significant level of wasted children, while together with Indonesia, it belongs to the 14 countries where 80 percent of the world’s stunted children reside. The study will identify and quantify the determinants of acute malnutrition or wasting in the Philippines.
