When evaluating growth in international adoption, it is hard to be “racially correct”. Nowadays, many countries have their specific growth chart for infants but many of the available are outdated from a small sample size, drawn from ethnic groups that may not represent your child’s ethnicity, based on malnourished populations, or all of the above. Even the growth charts of US are not perfect either but they are drawn from large population surveys and were currently modified to better reflect the racial-ethnic diversity in the US. In this article, you can find the growth charts which are used by the Center for Disease Control (CDC).
Girls and boys grow in different patterns and at different rates. So, girls and boys are measured on different growth charts. Also, the growth charts of infant and children are different. In this article, you can find the growth chart for infants. Sometimes, special growth charts are also used for children who have certain conditions, such as Down syndrome.
The 2000 CDC Growth Chart reference population includes data for both formula-fed and breast-fed infants, proportional to the distribution of breast- and formula-fed infants in the population. During the past two decades, approximately one-half of all infants in the United States received some breast milk and approximately one-third were breast-fed for 3 months or more. A Working Group of the World Health Organization is collecting data at seven international study centers to develop a new set of international growth charts for infants and preschoolers through age 5 years. These charts will be based on the growth of exclusively or predominantly breast-fed children.
All individual 2000 CDC growth charts have an initial publication date of May 30, 2000. For various reasons, modifications were made to charts after the initial publication date. For example, the individual charts were modified to create the clinical charts, which were made available on October 16, 2000. Subsequent modifications were made to selected clinical charts to correct or enhance particular aspects of the scales on the graphs. In all cases, the data points in the corresponding data file for each modified chart remain unchanged from the initial release on May 30, 2000. Where applicable, when selected clinical charts were further modified, the date is indicated on each chart. The clinical growth charts for stature-for-age were modified because the scale for inches was not correctly aligned with the metric scale. The clinical growth charts for infant length-for-age and infant weight-for-age were revised to improve the appearance of the scale for inches on the length charts by extending the indicators at ½ inch increments, and enhancing alignment of the English with the metric scales on both the length and weight scales.
