Mother's menstrual age linked to son's puberty: Study, Pixabay

The age at which a young woman experiences her first menstruation is associated with the age at which her son experiences puberty, according to a latest research.

While it has been known for some time that mothers’ age at puberty is associated with their daughters’, much less was known about the link with their sons’ age at puberty.

The findings, published in the journal Human Reproduction, suggested that mothers who reported having their first menstrual bleed earlier than their peers had sons with signs of puberty starting earlier than their peers.

“The relationship between first menstrual bleeding in mothers and the first menstrual bleeding in their daughters has been reported in several studies,” said Nis Brix, researcher at the Aarhus University in Denmark.

“The novelty of our study was to include other markers of pubertal development in daughters, such as different stages of breast and pubic hair development. The relationship in sons has only been sparsely investigated,” Brix added.

For the study, the researchers examined 15,822 children and interviewed the mothers twice during pregnancy and asked them to fill in a questionnaire when their children were seven.

“The largest difference was when hair started growing in the armpits, which started, on average, approximately two-and-a-half months earlier; their voices broke nearly two months earlier, acne started to develop nearly two months earlier and their first ejaculation of semen was nearly one and a half months earlier,” Brix said.

However, in girls, the largest difference was seen in breast development, which started up to six months earlier in those whose mothers had experienced earlier periods than their peers, or up to four months later in girls whose mothers had started puberty later than their peers.

Children Prone To Disorder With Mothers Having Diabetes During Pregnancy

Children and youths whose mothers had diabetes during their pregnancy are themselves at an increased risk of the disorder, say researchers, including one of Indian-origin.

The study showed that a child or teenager whose mother had gestational diabetes — diabetes during pregnancy — was nearly twice as likely to develop diabetes before the age of 22 years.

The association was found in children from birth to the age of 22 years, from birth to 12 years, and from 12 to 22 years, said the study, published in Canadian Medical Association Journal.

“Although Type-1 and Type-2 diabetes in parents are well-established risk factors for diabetes, we show that gestational diabetes mellitus may be a risk indicator for diabetes in the mother’s children before age 22,” said Kaberi Dasgupta, clinician-scientist from the McGill University in Canada.

“This link of diabetes in children and youth with gestational diabetes in the mother has the potential to stimulate clinicians, parents, and children and youth themselves to consider the possibility of diabetes if offspring of a mother with gestational diabetes mellitus develop signs and symptoms such as frequent urination, abnormal thirst, weight loss or fatigue,” said Dasgupta.
