Children’s and parents’ responses to three perceived height measures: relative height (Silhouette Apperception Test), sense of height (VAS short/tall), and judgment of appropriate height (yes/no) were compared to measured height. <b><i>Results:</i></b> Children and parents overestimated height at start (72%, 54%) and at 24 months (52%, 30%). Short children described themselves as tall until 8.2 years (girls) and 9 years (boys). Prior to treatment, 38% of children described their height as appropriate and at 3 months, 63%. Mother’s height, parental sense of the child’s tallness and age explained more variance in children’s sense of tallness (34%) than measured height (0%). <b><i>Conclusion:</i></b> Short children and parents overestimate height; a pivotal age exists for comparative height judgments. Even a small gain in height may be enough for the child to feel an appropriate age-related height has been reached and to no longer feel short. 2012-04-19 00:00:00 Children Growth hormone treatment Height determination Height prediction Puberty Quality of life Short stature Height perception
