Scheuermann's disease: focus on weight and height role

The aim of this cross-sectional case-control study is the comparison of the weight and height between a group of children with Scheuermann's disease (SD) and a comparable group of healthy ones and also the correlation of them with the degree and the morphology of the kyphotic curve. Following a school-screening program of 10,057 school students, aged between 11 and 17 years old, 175 adolescents with Scheuermann's disease were diagnosed. The mean height and weight of 175 adolescents diagnosed to have SD compared with this of a group of normal children taken randomly from the group of 9,882 healthy children screened. The control group was comparable with the study group concerning age (p = 0.605) and sex. The weight, height and body mass index (BMI) were significantly lower in the healthy (control) group (p < 0.001). However, there was no correlation between weight (r = -0.019, p = 0.804), height (r = 0.053, p = 0.484) and BMI (r = -0.177, p = 0.019) with the magnitude of kyphotic curve. There was also no correlation between weight (r = -0.27, p = 0.722), height (r = -0.025, p = 0.744) and BMI (r = -0.038, p = 0.619) with Voutsinas index as well. Scheuermann's disease is probably a multifactorial skeletal deformity. Weight and height do not seem to affect the magnitude and morphology of the main kyphotic curve in SD. It seems probably that this observation is not part of the pathogenetic mechanism of SD but a result of its cascade. The increased weight and height of these patients may be the secondary result of other disturbances (i.e. hormonal), which may play more crucial role in Scheuermann's disease pathogenesis.
