This study used a cross-sectional case-control design.
One hundred and thirty-nine 5- and 10-year-old children with CL/P and 299 age-matched controls.
Caries was recorded according to the International Caries Detection and Assessment System. Height and weight were recorded, and BMI was calculated as weight/height2.
There was no correlation between BMI and caries frequency. Weight, height, and BMI were significantly lower in all children with CL/P compared to controls. After adjustment for international adoption, only BMI was significantly lower in CL/P children compared to controls. Non-adopted children with CL/P were significantly heavier and longer than adopted children with CL/P.
Five- and 10-year-old children with corrected CL/P seemed to have a lower BMI than controls, but there was no association between BMI and caries frequency. Internationally adopted children with CL/P were lighter and shorter than non-adopted CL/P children and controls.
