Differences in birth weight (BW), low birth weight (LBW), and small for gestational age (SGA) between minority groups are difficult to interpret.

Misclassification of abnormal newborn size may lead to unnecessary intervention or conversely, overlooking babies requiring special care.

Newborn size charts should be used as screening tools, not as diagnostic tools.

Local population-based BW references, including minority-specific charts, are appropriate for research but not for clinical practice.
