Contrary to the common belief that diet and lifestyle hugely affect the onset of a girl's first period, a new study brings to light the fact that a mother's age has the biggest influence on her daughter's menarche.
The new study dispels the previously held thought that the average age of menarche, which is in between 11 to 12 years, has been falling as a result of childhood obesity, faster growth, and their bodies maturing early.
Scientists at the Institute of Cancer Research, a college of the University of London, have claimed that a woman’s age of menarche is significantly linked with that of her relatives, including her mother, older sister, grandmother or aunts, the Daily Mail reports.
