Public Health Implications of Altered Puberty Timing

Public 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...

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.

Timing 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 ...
