Timing of puberty

چکیده
Zusammenfassung Der Zeitpunkt des Pubertätsbeginns ist von Kind zu verschieden. Es zeigen sich familiäre und ethnische Merkmale sowie ein säkularer Trend, welche dem zeitlichen Aspekt einen gewissen Rahmen verleihen. Dennoch der Schritt in die Pubertät im einzelnen nicht so leicht vorherzusagen, da viele individuelle endogene exogene Elemente Einfluss haben. Wie große zeitliche Variabilität erklären? Ziel dieser Arbeit es, eine kurze Übersicht über jene Faktoren geben, Timing bedeutende Rolle spielen.

Puberty-timing is everything!
Puberty is a dynamic period of physical growth, sexual maturation, and psychosocial achievement that generally begins between age 8 and 14 years. The age of onset varies as a function of sex, ethnicity, health status, genetics, nutrition, and activity level. Puberty is initiated by hormonal changes triggered by the hypothalamus. Children with variants of normal pubertal development--both early ...
متن کاملTiming of puberty by photoperiod.
Photoperiod cues play an important role in the timing of puberty in the female lamb. Removal and replacement of photoperiod cues by denervation of the pineal gland and timed melatonin infusions, respectively, indicate that the pathway for transmission of photoperiod information develops well before puberty. This is reinforced by manipulation of artificial photoperiods during various periods of ...
متن کاملPublic health implications of altered puberty timing.
Changes in puberty timing have implications for the treatment of individual children, for the risk of later adult disease, and for chemical testing and risk assessment for the population. Children with early puberty are at a risk for accelerated skeletal maturation and short adult height, early sexual debut, potential sexual abuse, and psychosocial difficulties. Altered puberty timing is also o...
متن کاملGenetic Regulation of Puberty Timing in Humans.
Understanding the regulation of puberty timing has relevance to developmental and human biology and to the pathogenesis of various diseases. Recent large-scale genome-wide association studies on puberty timing and adult height, body mass index (BMI) and central body shape provide evidence for shared biological mechanisms that regulate these traits. There is a substantial genetic overlap between...
متن کاملRole of environmental factors in the timing of puberty.
Puberty-timing measures have historically been used as indicators of adequate nutrition and growth. More recently, these measures have been examined in relation to exposure to estrogenic or antiandrogenic agents, as well as other environmental factors. The scientific community has debated whether puberty timing is occurring earlier today than in the mid-1900s in the United States and, if so, wh...
