Malnutrition is a social problem in the Philippines that affects many children. The document discusses the different forms of malnutrition - underweight, wasting, and stunting - and provides data on the prevalence of each from national surveys. While stunting has decreased from 39% to 30% from 1993 to 2013, wasting has remained the same at around 7.9%. The causes of malnutrition are linked to poor nutrition, unhealthy conditions, and nutritional deficiencies. The effects of malnutrition can impair cognitive development in individuals and lead to low economic growth at the societal level. The government has committed to addressing malnutrition through programs that promote infant and young child feeding and the distribution of supplements.
