Among researchers who study puberty, the Tanner scale is commonly considered the "gold standard" for assessing pubertal status when it is conducted by a trained medical examiner. [5] In HIV treatment, the Tanner scale is used to determine which regimen to follow for pediatric or adolescent patients on antiretroviral therapy (adult, adolescent ...
In particular, puberty has been explored as a contributor to changes in adolescent sleep. Luteinizing hormone (LH) is secreted during sleep at the onset of pubertal maturation, pointing to an important relationship between sleep and pubertal development.

Puberty is considered delayed when the child has not begun puberty when two standard deviations or about 95% of children from similar backgrounds have. [7] [8] [9]In North American girls, puberty is considered delayed when breast development has not begun by age 13, when they have not started menstruating by age 15, [2] and when there is no increased growth rate.

Subsequent studies have confirmed these findings, explored the impact of school start times on the sleep needs and patterns of adolescents., [15] and demonstrated a "phase shift" in the release of melatonin at puberty, which appears to be involved in shifting the sleep-wake cycle several hours later during the adolescent years.
Adolescence is a critical period in social development because adolescents can be easily influenced by the people they develop close relationships with. This is the first time individuals can truly make their own decisions, which also makes this a sensitive period.
Early pubertal timing, or precocious puberty, is associated with negative outcomes in both genders. Early maturing girls have been found to be at risk for teenage pregnancy, [34] drinking [35] and weight problems, [36] [37] and giving birth to low birth weight infants. [38]
