Abbreviated Name:
Children aged under 5 years who are obese
Indicator Name:
Children aged under 5 years who are obese
Domain:
Health determinants and risks / Risk factors
Related Terms:
Child obesity, overweight, underweight, stunting, wasting
Definition:
Percentage of obesity (weight-for-height above +3 standard deviations of the WHO Child Growth Standards median) among children aged 0-59 months.
Measurment Method:
Percentage of children aged 0-59 months years obese for age = (Number of children aged 0-59 months that are over three standard deviations from the median weight-for-height of the WHO Child Growth Standards / Total number of children aged 0-59 months that were measured) x 100. Children`s weight and height are measured using standard technology, e.g. children less than 24 months are measured lying down, while standing height is measured for children 24 months and older. The data sources include national nutrition surveys, any other nationally-representative population-based surveys with nutrition modules, and national surveillance systems. Number of children aged 0-59 months that are over three standard deviations from the median weight-for-height of the WHO Child Growth Standards.
Numerator:
Number of children aged 0-59 months that are over three standard deviations from the median weight-for-height of the WHO Child Growth Standards
Denominator
Total number of children aged 0-59 months that were measured
Estimation method:
WHO maintains the Global Database on Child Growth and Malnutrition, which includes population-based surveys that fulfill a set of criteria. Data are checked for validity and consistency and raw data sets are analyzed following a standard procedure to obtain comparable results. Prevalence below and above defined cut-off points for weight-for-age, height-for-age, weight-for-height and body mass index (BMI)-for-age, in preschool children are presented using z-scores based on the WHO Child Growth Standards. A detailed description of the methodology and procedures of the database including data sources, criteria for inclusion, data quality control and database work-flow, are described in a paper published in 2003 in the International Journal of Epidemiology (de Onis, Blössner 2003).
