Children who are exposed to violence such as physical, emotional, or sexual abuse are more likely to experience faster biological ageing, including pubertal development and increased symptoms of depression, finds a research.

The study showed that in children who experienced early life violence, accelerated epigenetic ageing was associated with increased symptoms of depression.

This means that faster biological ageing may be one way that early life adversity “gets under the skin” to contribute to later health problems.

Conversely, children exposed to forms of early life deprivation including neglect and food insecurity were more likely to experience their puberty at a later stage compared with their peers, the researchers said.

“The findings demonstrate that different types of early-life adversity can have different consequences for children’s development,” said Katie McLaughlin, postdoctoral student at the University of Washington.

For the study, published in the journal Biological Psychiatry, the team examined 247 children and adolescents aged eight to 16 years.

The results indicated that accelerated ageing following exposure to violence early in life can already be detected in children as young as eight years old.

In addition, the team found that there is a need for increased societal investment in reducing the exposure of children to violence and for biomedical and psychological research to reduce the impact of these experiences throughout the lives of these vulnerable individuals.

The association between the ageing metrics and symptoms of depression may offer a way for doctors to identify children who need help, the researchers said.

“Accelerated epigenetic age and pubertal stage could be used to identify youth who are developing faster than expected given their chronological age and who might benefit from intervention,” McLaughlin noted. (IANS)

Loneliness And Depression Can Be Linked to Social Media: Study

It is unclear if the depressing effects of social media will cross generational lines to older or younger people

University of Pennsylvania researchers say that for the first time they have linked social media use to increases in depression and loneliness.

The idea that social media is anything but social when it comes to mental health has been talked about for years, but not many studies have managed to actually link the two.

To do that, Penn researchers, led by psychologist Melissa Hunt, designed a study that focused on Facebook, Snapchat and Instagram.

The results were published in the November issue of the Journal of Social and Clinical Psychology.

How study worked

The study was conducted with 143 participants, who before they began, completed a mood survey and sent along photos of their battery screens, showing how often they were using their phones to access social media.

“We set out to do a much more comprehensive, rigorous study that was also more ecologically valid,” Hunt said. That term, ecologically valid, means that the research attempts to mimic real life.

The study divided the participants into two groups: The first group was allowed to maintain their normal social media habits. The other, the control group, was restricted to 10 minutes per day on each of the three platforms: Facebook, Snapchat and Instagram.

The restrictions were put in place for three weeks and then the participants returned and were tested for outcomes such as fear of missing out (FOMO), anxiety, depression and loneliness.

Results of study

The results showed a very clear link between social media use and increased levels of depression and loneliness.

“Using less social media than you normally would leads to significant decreases in both depression and loneliness,” Hunt said. “These effects are particularly pronounced for folks who were more depressed when they came into the study.”

She calls her findings the “grand irony” of social media.

What is it about social media that’s just so depressing?

Hunt says that it’s two major things. The first is that social media invites what Hunt calls “downward social comparison.” When you’re online, it can sometimes seem that “everyone else is cooler and having more fun and included in more things and you’re left out,” she said. And that’s just generally demoralizing.

The second factor is a bit more nuanced.

“Time is a zero-sum game,” Hunt told VOA. “Every minute you spend online is a minute you are not doing your work or not meeting a friend for dinner or having a deep conversation with your roommate.”

And these real life activities are the ones that can bolster self-esteem and self worth, Hunt said.

What to learn

So what’s the takeaway?

People are on their devices, and that’s not going to change, she said. But as in life, a bit of moderation goes a long way.

“In general, I would say, put your phone down and be with the people in your life,” she added.

Hunt pointed out a few caveats to the study. First, it was done exclusively with 18- to 22-year-olds, and it is unclear if the depressing effects of social media will cross generational lines to older or younger people, Hunt said. But she expects her results should generalize at least for people through the age of 30.
