CDC promotes one set of growth charts for all racial and ethnic groups.
Racial- and ethnic-specific charts are not recommended because studies
support the premise that differences in growth among various racial and
ethnic groups are the result of environmental rather than genetic
influences.
Also, the reference population lacked sufficient numbers of specific
racial/ethnic groups to consider separate charts.
Although some studies using BMI-for-age to evaluate at risk of
overweight and overweight have found differences by ethnic and racial
groups, factors that affect differences in growth among racial and ethnic
groups, if they truly exist, remain unclear and more research is needed to
clarify the issue.
