The timing of pubertal events is regulated by genetics. • Nutrition and health are strong environmental factors. • Puberty occurs earlier in adolescents who are well nourished and healthy than those who are not. • Girls enter puberty at younger age (faster/early) when their mothers romantic relationships were stressful, girls have their menstrual period at younger age when mothers used harsh punishments on them as preschoolers, • Girls who experience socioeconomic stress; the hormones elicited by this stress may help to activate the hormones that trigger menarche.
