title: [Physical and psychological changes in relation to the period before and after onset of the menarche].
abstract: This cross-sectional study on 452 girls between 11 and 16 years of age examines the physical and psychological changes in the period 30 months before and 60 months after onset of menarche. Indicators of maturity showed the strongest alterations around menarche. In the majority of the physical characters (e. g. thickness of skinfold) adult values are achieved only a longer period after menarche, whereas others (e. g. dimensions of the head) terminate growth already largely by onset of menarche. We found out a minimum in development of thickness of skinfold at the time of menarche indicating a "second loss of body fat" in girls. In four different dimensions of personality (health, anxiety, neuroticism, power of concentration) menarche causes an interruption of the psychic development, and that in an adverse sense.
