A new European study suggests that the age of which a woman begins her menstrual cycle may determine at what age her son will begin puberty.
The research was conducted at the Aarhus University in Denmark. The study was published in the journal Human Reproduction. Their study is the largest currently every that investigates the link between a mother’s first menstruation and the age puberty begins in her children whether boy or girl.
There have been previous studies on the subject of age in a woman’s first period and of it will occur at the same age for her daughter, but the results remain inconclusive.
To conduct the study, researchers looked at 15,822 children who were born between the year 2000 to 2003. They followed the children until 2016. Starting at the age of 11, they were asking the children to complete questionnaires every six months. The questions were about puberty. Their mothers were asked at what age did the first begin their menstruation.
European Study Shows Association With Mothers First Menstruation and Their Children’s Puberty
Researchers were able to find out that woman who began their periods at early ages had sons who began puberty at early ages. The older they were when they had their first period, the older their son would be to began puberty.
The same associations were also true with their daughters as well.
The largest difference in the study was the age at which they began to grow hair on their armpits. On average, it began to grow two and a half months earlier. Their voices began to change two months earlier, as well as their acne, came about two months earlier.
In over a century, it seems that puberty has begun to start earlier and earlier. Researchers attribute this to health and better living standards. Unfortunately, a younger age over puberty also has links to an increase in the risk of certain diseases later on in life. Those diseases include various cancers and cardiovascular disease. Also, diabetes.
