Brief Summary

Short stature is defined as a height less than -2 Standard Deviations (SD) for age and a slowing of growth velocity by a loss of 1 SD/year. The causes of short stature are multiple (chronic diseases, growth hormone deficiency, hypothyroidism, hyperadrenocorticism, genetic syndromes, etc.). However, nearly 30% are considered idiopathic, with no identified etiology (Naccache et al., unpublished). Growth hormone (GH) is secreted in a pulsatile manner with maximum peaks primarily at night, raising questions about the relationship between sleep disturbances and short stature. In children, one of the main causes of sleep disturbances in the digital age is screen use, which is becoming increasingly important, particularly in the pediatric population.
