Daily measurements of the heights of two children from June 1984 to May 1985.
Two children, a sister and a younger brother, were measured with regard to stature, head and neck height, iliospinal height, and trunk length, every morning and evening for one year. They were 7.5 years old and 6.6 years old, respectively, on the first day of the investigation. In both children, stature and trunk length, but not the other dimensions, were longer in the morning and shorter in the evening. Almost all the year's statural elongation was due to lower limb elongation, but there was a sharp upward turn in April-May which resulted from an increase in trunk length. The head and neck height curves were flat throughout the year.
