[Osteogenesis imperfecta: quality of life in children].

The impact produced by osteogenesis imperfecta in childrens' quality of life almost has not been reported; 65 children, 38 males, were evaluated according to the questionnaire PedsQL 4.0 Argentinean Spanish version. Median age was 7.76 years; 35 children with OI type I were compared with 30 type III-IV (according to Sillence Classification) finding significant difference in the physical domain in both visions, children and parents, and only in parents' vision in the social area. Multivariate analysis showed an association between better PedQL scores and treatment compliance (coef. β= 19.41 p= 0.03) in children's vision. In parental report on the other hand, the association was found with greater pamidronate doses (coef. β 1.44 p=0.037), lower height compromise (coef. β= 3.8; p= 0.039) and less number of fractures (coef. β= 0.69; p= 0.003).
