Stature of Russian children with isolated cleft lip and palate.

OBJECTIVE

To evaluate the stature of Russian children with cleft lip and palate (CLP).

DESIGN

One hundred twelve Russian children predominantly with repaired unilateral CLP 4 through 10 years of age underwent studies including height measurement, physical examinations, and record review. Children with health concerns that could affect growth were excluded. U.S. growth data from the National Center for Health Statistics (NCHS) and Russian parental heights were used in the absence of Russian growth norms.

RESULTS

Based on U.S. norms, the distribution curve for heights for the Russian children was largely confined to the +1 to -1 standard deviation (SD) range. Sixty-two percent of the Russian children had heights below the 50th percentile for American female and male children of the same age. The proportion of children found outside the +1 to -1 SD range approximated the proportion expected statistically for the general population, with 14.4% < -1 SD (16th percentile) and 12% > +1 SD (84th percentile). A total of 3.6% of the children ranked below the third percentile, which is close to the expected 3%. Russian parents' (n = 209) mean heights were 0.5 SD below NCHS's 50th percentile values for adults.

CONCLUSION

These results indicate that there is no increased risk of true short stature in 4- to 10-year-old Russian children with repaired CLP.
