Child wasting refers to a child who is too thin for his or her height and is the result of recent rapid weight loss or the failure to gain weight. A child who is moderately or severely wasted has an increased risk of death, but treatment is possible. Child wasting is one of the World Health Assembly nutrition target indicators.\n\n#### Definition\nPrevalence of wasting (weight for height <-2 standard deviation from the median of the World Health Organization (WHO) Child Growth Standards) among children under 5 years of age. Numbers affected (thousands) of wasting (weight for height <-2 standard deviation from the median of the World Health Organization (WHO) Child Growth Standards) among children under 5 years of age.\n\n#### Method of measurement\n**Methods and Guidance:** WHO and UNICEF provide recommendations for data collection, analysis and reporting on anthropometric indicators in children under 5 years old. (Recommendations for data collection, analysis and reporting on anthropometric indicators in children under 5 years old. Geneva: World Health Organization and the United Nations Children\u2019s Fund (UNICEF), 2019. Licence: CC BY-NC-SA 3.0 IGO.) **Analysis Tool** To facilitate re-running of nutritional survey data based on standardized approach, WHO has developed an online tool to analyse child anthropometric data. The WHO Anthro Survey Analyzer aims to promote best practices on data collection, analyses and reporting of anthropometric indicators. It offers analysis for four indicators: length/height-for-age, weight-for-age, weight-for-length, weight-for-height and body mass index-for-age. (WHO Anthro Survey Analyser and other tools)\n\n#### Method of estimation\n**Data collection method** UNICEF and WHO employ their existing networks to obtain data. WHO relies on the organization\u2019s structure and an expanding network developed following the creation of the WHO Global Database on Child Growth and Malnutrition. For UNICEF, the cadre of dedicated data and monitoring specialists working at national, regional and international levels in 190 countries routinely provides technical support to produce child malnutrition estimates through surveys and administrative systems and analyses for improved programme planning. The World Bank Group provides estimates available through the Living Standard Measurement Surveys (LSMS). **Method of computation** National estimates from primary sources (e.g., from household surveys) used to generate the JME global estimates are based on standardized methodology using the WHO Child Growth Standards as described in \u201cThe UNICEF-WHO-World Bank Joint Child Malnutrition Estimates (JME) standard methodology\u201d and WHO Anthro Survey Analyser. The JME global estimates are generated using smoothing techniques and covariates applied to quality-assured national data to derive trends and up-to-date estimates. Worldwide and regional estimates are derived as the respective country averages weighted by the countries\u2019 under-five population estimates (UNPD-WPP latest available edition) using annual JME global estimates for 205 countries. However, estimates are only presented in the cases where a country has input data. In line with WHO\u2019s data principle to use transparent models and methods, all codes used to generate estimates for the latest round and prior rounds are openly available on WHO\u2019s GitHub
