At what age did you start menstruating?

When women are menstruating, they should be careful not to eat some cold foods during this period. At the same time, they should also reduce the choice of some high-calorie foods, otherwise it will cause physical discomfort. A common example is ice cream, which is a favorite of many women. It should not be eaten during the menstrual period, otherwise it will cause dysmenorrhea. At what age do people have menstruation? This is also something that many parents do not understand. The following is a detailed introduction.

At what age did you start menstruation?

A girl's first menstruation is called menarche. Girls and their parents are very concerned about the timing of menarche and hope that the timing of menarche is normal. However, we don’t quite know when the normal menarche should be, which makes it difficult to judge whether the timing of menarche is normal. According to relevant statistics in our country, most girls have their first menstruation between the ages of 12 and 16.

For example, from 1978 to 1980, relevant units conducted a survey on the menstrual conditions of 130,000 women in 29 provinces, municipalities, and autonomous regions across the country and found that the youngest age of menarche was 9 years old and the oldest was 21 years old. The vast majority were between 12 and 19 years old, with an average of 15 years old. The most common age of menarche for urban women is 15 years old, while for rural women it is 16 years old.

Another survey data from 1978-1979 showed that the earliest average age of menarche was in Guangzhou and Beijing, at 13.3 and 13.6 years old respectively; the latest was in Shandong, at an average of 15.4 years old. The early or late menarche is generally believed to be closely related to genetics. If the mother's menarche is early, the daughter's menarche will also be early; if the mother's menarche is late, the daughter's menarche may also be late.

But this is not absolute, it will also be affected by other factors. The early or late menarche is also related to the degree of cohabitation in urban and rural areas. From the above statistics, we can see that the age of menarche for urban girls is earlier than that for rural girls.

The reason for this is that it is generally believed that among people with a higher standard of living, good nutrition and health, girls not only grow faster physically, but also have their first menstruation earlier. Some people also believe that because the urban lifestyle increases contact between the sexes, some have more opportunities to come into contact with sexual knowledge, which in turn causes the nervous system to regulate the endocrine glands, causing the sex-related endocrine system to become active prematurely, thus bringing forward menarche.

After understanding the age at which menstruation occurs, parents should explain things to their children when they have their period, to avoid them looking for answers on their own, which may lead to other problems. After their period begins, their diet should be properly matched, which will help their physical growth in all aspects.
