Bodycomposition measurement is useful in the diagnosis of pathology, assessment of disease process and response to treatement in many endoclonologic and metabolic diseases. The Techniques used currently are mostly indirect, often expensive,
difficult
and time-consuming. A new method for estimation of body composition, infrared interactance, is rapid, safe, noninvasive, and may be useful in research and clinical studies.
Body composition was assessed in 51 children and adolescants with insulin-dependent diabetes mellitus by infrared interactance method using a Futrex 5000A body fat content analyzer. Percentage body fat of pubertal girls was 26.1±7.6%,
significantly
greater than prepubertal girls (17.9%, 0<0.01) and pubertal boys (19.9%, p<0.05). Body fat content was increased through puberty in girls. but not increased in boys. Our data do not explain why body fat of pubertal boys was not increased. There
was
no
significant association of insulin dose and HbA1C level with percentage body fat. Thus, we had to attempt measure calorie intake, activity level and diet composition. Our data revealed that dietary carbohydrates may prompt fat deposition, but
energy
balance does not explain the differences between pubertal girls and boys.
In conclusion, Body fat increased through puberty in girls, but the etiology of differences in pubertal girls and boys is not clear, and in view of potential adverse effect of fat depostion of long-term health, further larger case-contolled study
will
be necessary.
