Advantages of Using the WHO Growth Charts to Assess the Growth of Children from Birth to Aged 2 Years
The WHO standard charts use growth of the breastfed infant as the norm for growth.
- The WHO standards bring the tools used to assess growth and national guidelines that recommend breastfeeding as the optimal infant feeding method into agreement.1
The WHO standards are based on high-quality data collected for children younger than aged 2 years .
- The WHO growth standard charts were created with longitudinal length and weight data measured at frequent intervals.2-3
- The CDC growth reference charts were based on cross-sectional length and weight data. However, weight data were not available for infants aged birth to 2 months, and the sample sizes were small for sex and age groups during the first 6 months of age.4
