Nutrition has been the most involved factor in the timing of menarche in many industrialized nations over the past 150 years. Improvements in nutrition and overall health have led to earlier onset of menstruation in girls. This trend has been observed globally and has been linked to the increase in the consumption of animal protein and overall caloric intake. Other factors, such as education and genetics, may play a role but have not been found to have as significant an impact as nutrition.
