<p>For the survey estimates included in the JME joint database of primary sources, re-analysis based on standardized methodology using the WHO Child Growth Standards as described in Recommendations for data collection, analysis and reporting on anthropometric indicators in children under 5 years old (<a href="https://data.unicef.org/resources/data-collection-analysis-reporting-on-anthropometric-indicators-in-children-under-5/">WHO/UNICEF 2019</a>) and WHO Anthro Survey Analyser (<a href="https://www.who.int/tools/child-growth-standards/software">WHO, 2019</a>) is applied whenever microdata are available to enhance comparability across the time series. Country teams are encouraged to use the WHO Anthro Survey Analyser (<a href="https://www.who.int/tools/child-growth-standards/software">WHO, 2019</a>) to undertake survey analysis and harmonize with the global standard analysis methods. </p>
<p>For the inclusion of survey estimates into the JME database, the inter-agency group applies a set of survey quality assessment criteria. When there is insufficient documentation, the survey is not included until information becomes available. Discrepancies between results from standard methodology and those reported may occur for various reasons, for example, the use of different standards for z-score calculations, imputation of the day of birth when missing, the use of rounded age in months, the use of different flagging systems for data exclusion. For surveys based on the previous NCHS/WHO references, and for which raw data are not available, a method for converting the z-scores to be based on the WHO Child Growth Standards is applied (<a href="http://www.biomedcentral.com/1471-2431/8/19">Yang and de Onis, 2008</a>). In addition, when surveys do not cover the age interval 0-59 months, or are only representative of the rural areas, an adjustment based on other surveys for the same country, is performed. Any adjustment or conversion is transparently stated in the annotated joint data set.</p>
<p>The JME country modelled estimates, which are based on smoothing techniques and covariates, as described elsewhere (<a href="https://pubmed.ncbi.nlm.nih.gov/30430613/">McLain et al. 2018</a>), vary from estimates from primary data sources such as household surveys, but in most cases the 95 per cent confidence bounds of the country modelled estimates for a given country in a given year fall within the 95 per cent confidence bounds of the estimate from the primary source for the corresponding country and year(s).</p>

<h2> Источники расхождений: </h2>
<p> Стандартный подход к анализу для создания совместного набора данных нацелен на максимальную сопоставимость оценок по странам. Для включения оценок обследования в набор данных публикации "Совместные оценки недоедания" (JME) межучрежденческая группа применяет критерии оценки качества обследования. Если документации недостаточно, данные обследования не включаются до тех пор, пока информация не станет доступной. Когда доступны исходные данные и возникает вопрос о подходе к анализу, повторный анализ данных выполняется по стандартной методологии. Расхождения между результатами стандартизированного подхода и результатами в представленном отчете могут возникать по разным причинам, например, из-за использования разных стандартов для расчета z-оценки, вменения дня рождения в случае его отсутствия, использования округленного возраста в месяцах, использования разных систем отметок для исключения данных. Для обследований, основанных на предыдущих справочных материалах Национального центра медицинской статистики / Всемирной организации здравоохранения (NCHS / ВОЗ) и по которым исходные данные недоступны, применяется метод преобразования z-оценок на основе Стандартов роста детей ВОЗ (Yang and de Onis, 2008). Кроме того, если обследования не охватывают возрастной интервал от 0 до 5 лет или являются репрезентативными только для сельской местности, то выполняется корректировка на основе других обследований для той же страны. Любая корректировка или преобразование ясно и понятно объясняется в аннотированном совместном наборе данных.</p>

<p>The standard analysis approach to construct the joint data set aims for a maximum comparability of country estimates. For the survey estimates included in the JME joint database of primary sources, re-analysis based on standardized methodology using the WHO Child Growth Standards as described in Recommendations for data collection, analysis and reporting on anthropometric indicators in children under 5 years old (<a href="https://data.unicef.org/resources/data-collection-analysis-reporting-on-anthropometric-indicators-in-children-under-5/">WHO/UNICEF 2019</a>) and WHO Anthro Survey Analyser (<a href="https://www.who.int/tools/child-growth-standards/software">WHO, 2019</a>) is applied whenever microdata are available to enhance comparability across the time series.

<p>For the inclusion of survey estimates into the JME databaset, the inter-agency group applies a set of survey quality assessment criteria. When there is insufficient documentation, the survey is not included until information becomes available. When raw data are available, and there is a question about the analysis approach, data re-analysis is performed following the standard methodology. Discrepancies between results from standardised approach methodology and those reported may occur for various reasons, for example, the use of different standards for z-score calculations, imputation of the day of birth when missing, the use of rounded age in months, the use of different flagging systems for data exclusion. For surveys based on the previous NCHS/WHO references, and for which raw data are not available, a method for converting the z-scores to be based on the WHO Child Growth Standards is applied (<a href="http://www.biomedcentral.com/1471-2431/8/19">Yang and de Onis, 2008</a>).

<p><strong>Data availability:</strong></p>
<p>The JME modelled country estimates from 2000 to 2022 for overweight were released for 161 countries that had at least one primary data source (e.g., from household survey) included in the 2023 JME country database.</p>

Survey years range from 1983 to the year before the JME release. Worldwide and regional annual estimates are available from 2000 to the year before the JME release. </p>
<p><strong>Disaggregation:</strong></p>
<p>Country, regional and worldwide JME estimates refer to the age group of children under 5 years, sexes combined. Disaggregations are currently not available for the JME modelled estimates. However, a disaggregated dataset of national primary sources with sub national and stratified estimates (e.g., sex, age groups, wealth, mothers&apos; education, residence) is available.</p>

<h1> Доступность данных </h1>
<h2> Описание: </h2>
<p>Для более 150 стран. </p>
<h2> Временные ряды: </h2>
<p>На страновом уровне данные предоставляются за те годы, когда данные обследований включены в объединенный набор данных. Годы проведения обследований варьируются с 1983 по 2016 годы. Для глобального и регионального уровней оценки данные представляются с 1990 года и до последней имеющейся оценки на момент публикации годовых данных (то есть в выпуске Совместных оценок недоедания за сентябрь 2016 года последняя доступная оценка была за 2015 год).</p>
<h2> Дезагрегирование: </h2>
<p> Глобальные и региональные оценки относятся к возрастной группе детей до 5 лет, без разбивки по полу. Дезагрегированные страновые данные доступны в большинстве обследований домашних хозяйств и ЮНИСЕФ - ВОЗ - Группа Всемирного банка расширяют набор объединенных данных, чтобы включить субнациональные и стратифицированные оценки (например, по полу, возрастным группам, благосостоянию, образованию матери, месту жительства) в 2017 году. </p>

<p><strong>Data availability:</strong></p>
<p>More than 150 countries.</p>
<p><strong>Time series:</strong></p>
<p>At country level, dataThe JME modelled country estimates from 2000 to 2022 for overweight were released for 161 countries that had at least one primary data source (e.g., from household survey) included in the 2023 JME country database.</p>
<p><strong>Time series:</strong></p>
<p>At country level, JME country modelled estimates from 2000 to the year before the JME release ) are providesented for the years where surveys are included in the joint datasetcountries with at least one data point (e.g., from survey/surveillance included in the joint database of primary data sources. Survey years range from 1983 to 2016. Fthe year before the globalJME release. Worldwide and regional levels,annual estimates for the years 1990 to the latest available estimate upon release each year (i.e. in Sept 2016 edition of the Joint Malnutrition Estimates the latest available estimate was for 2015)are available from 2000 to the year before the JME release. </p>
<p><strong>Disaggregation:</strong></p>
<p>Global and regionalCountry, regional and worldwide JME estimates refer to the age group of children under 5 years, sexes combined. Disaggregated country data areions are currently not available in a majority of household surveys and UNICEF - WHO- The World Bank Group are expanding the jointfor the JME modelled estimates. However, a disaggregated data set to includeof national primary sources with sub national and stratified estimates (e.g., sex, age groups, wealth, mothers&apos; education, residence) in 2017s available.</p>

<p>Data consistency and quality checks described above are conducted for each potential primary data source (e.g., household survey) before inclusion in the JME country database of primary sources that are used to generate the JME modelled estimates. Cross-validation exercises are performed for the modelled estimates to ensure the method generates estimates that are aligned to national data points. Country consultations with SDG 2.2 focal points an held every other year also provide opportunity to ensure the estimates include all recent and relevant country data. </p>

<p>The quality criteria established in the 2019 UNICEF/WHO guidance (<a href="https://data.unicef.org/resources/data-collection-analysis-reporting-on-anthropometric-indicators-in-children-under-5/">WHO/UNICEF, 2019</a>) were used to update the JME primary data source review form . The JME review form is used to abstract key information including methodological details (e.g., sampling procedures, description of anthropometrical equipment), data quality outputs (e.g., response rates, weight and height distributions, percentage of cases that were flagged as having implausible anthropometry outcomes according to the WHO Child Growth Standards) and the malnutrition prevalence estimates from each primary data source (e.g., household survey) under review. One JME working group member fills in the review form for each data source and when information is missing or further details are required, the country teams are contacted. Once all information is available and the JME primary data source review form is completed, each data source is reviewed by the three agencies (UNICEF, WHO, WB) which form the JME working group. This allows for a thorough and efficient standard joint review of each data source by the three agencies prior to inclusion in the JME country database of primary sources (e.g., household surveys) that are used to generate the JME country modelled estimates. </p>

<p>The JME working group, which was formed in 2011 with representatives from UNICEF, WHO and the World Bank, is responsible for management of the processes used to develop regular updates of the JME estimates. This includes the regular update of the country database of surveys used to generate the JME country modelled estimates, for which regular communication with regional and country teams allows the JME working group to secure microdata for re-analysis according to the standard method. The JME working group also continuously review methods and considers and tests different methodologies to improve the estimates as necessary. Additionally, a Technical Expert Advisory Group on Nutrition Monitoring (TEAM), jointly established by UNICEF and WHO, provides advice on nutrition monitoring methods and processes, including on the JME.</p>
