An alteration of 25 OH Vit D metabolism and of enteric proteins participating in calcium transport, decrease calcium intestinal absorption and bone mineralization, in CD Growth and bone mineralization of 36 celiac children of both sexes, aged 6 to 16 years and with as an average of 5 years of satifactory compliance with the gluten fee diet were evaluated through a paired case, control study. Nutritional and growth status were studied through weight/height, body fat and height/age measurements, according to WHO charts. Dietary compliance was verified by determination of antigliadin and antiendomisium antibodies. Bone mineral density (BMD) was measured in the spine, hip and total body with a Lunar radiologic densitometer and results were expressed as Z score, using reference from healthy spanish children population. For statistical analysis student T test and relative risk were calculated. A significant lower statural adequation was obsserved in CD(96.6±5.5) compared with the controls (101.5±5.4) while no differences in ponderal adequation and body fat were detected. CD patients had significant lower BMD in total body, spine and femoral neck(-0.19±0.63.-0.92±0.98 and -0.3±0.99 respectivelly) than controls (0.47±0.64, 0.23±1.37 and 0.29-±1.09 respectivelly. CD patients were at increased risk of a bone mineralization below -1 s.d. in total body and spine (2.13 and 1.96 times respectivelly) than controls. These results indicate that children with CD are at high risk of developing osteoporosis in the adult life.
