Fathers, take note! Taking too much stress may affect the brain development of your kids, a new study has claimed.

According to the researchers, the stress changes the father’s sperm which can then alter the brain development of the child.

Previously, the researchers including Tracy Bale at the University of Maryland School found that adult male mice, experiencing chronic periods of mild stress, have offspring with a reduced response to stress; changes in stress reactivity have been linked to some neuropsychiatric disorders, including depression and PTSD.

They isolated the mechanism of the reduced response; they found that the father’s sperm showed changes in a genetic material known as microRNA. MicroRNA are important because they play a key role in which genes become functional proteins.

Now, the researchers have unraveled new details about these microRNA changes.

In the male reproductive tract, the caput epididymis, the structure where sperm matures, releases tiny vesicles packed with microRNA that can fuse with sperm to change its cargo delivered to the egg, they said.

The caput epididymis responded to the father’s stress by altering the content of these vesicles, the researchers added.

The result of the study, presented at AAAS 2018 annual meeting in Austin, suggests that even mild environmental challenges can have a significant impact on the development and potentially the health of future offspring.

Weigh Gain in Women Can Be Cause Due To High Stress Jobs: Study

Efforts to reduce work-related stress would likely achieve a decrease not only in weight gain but also in the incidence of ill health

Are you gaining weight suddenly? Blame increased stress at workplace, say researchers who found that heavy pressure at work predisposes women to weight gain, irrespective of whether they have received an academic education.

The findings, led by the University of Gothenburg in Sweden researchers, showed that long-term exposure to high job demands played a part only for women. In just over half of the women who had been subjected to high demands, a major increase in weight took place over the 20 years.

This gain in weight was some 20 per cent higher than in women subject to low job demands.

On the other hand, women and men with a low degree of control in their work more frequently gained considerable weight, defined as a weight gain of 10 per cent or more.

“We were able to see that high job demands played a part in women’s weight gain, while for men there was no association between high demands and weight gain,” said lead author Sofia Klingberg, a researcher at the varsity.

“When it came to the level of demands at work, only the women were affected. We haven’t investigated the underlying causes, but it may conceivably be about a combination of job demands and the greater responsibility for the home that women often assume. This may make it difficult to find time to exercise and live a healthy life,” Klingberg added,

For the study, published in the journal International Archives of Occupational and Environmental Health, the team included 3,872 women and men who were investigated on three occasions over a 20-year period with respect to such variables as body weight and demands and control at work.

They were followed either from age 30 to 50 or from 40 to 60.

Efforts to reduce work-related stress would likely achieve a decrease not only in weight gain but also in the incidence of ill health, including cardiovascular disease and diabetes, the researchers noted. (IANS)
