Study used data from cell phone apps and watches, brain activity and lifestyle factors to generate predictions of depression; results could lead to individualized treatment plans for mental health
According to the National Alliance on Mental Illness and the World Health Organization, depression affects 16 million Americans and 322 million people worldwide. Emerging evidence suggests that the COVID-19 pandemic is further exacerbating the prevalence of depression in the general population. With this trajectory, it is evident that more effective strategies are needed for therapeutics that address this critical public health issue.
In a recent study, publishing in the June 8, 2021 online edition of Nature Translational Psychiatry, researchers at University of California San Diego School of Medicine used a combination of modalities, such as measuring brain function, cognition and lifestyle factors, to generate individualized predictions of depression.
The machine learning and personalized approach took into account several factors related to an individual’s subjective symptoms, such as sleep, exercise, diet, stress, cognitive performance and brain activity.
A new study, by researchers Drs. Boers, Afzali and Conrod who are affiliated with CHU Sainte-Justine Research Center and the Department of Psychiatry at the University of Montreal, reveals that social media use, television viewing and computer use, but not video gaming, are linked to an increase in anxiety symptoms among adolescents.
The study, published in academic outlet the Canadian Journal of Psychiatry, shows that a higher than average frequency of social media use, television viewing and computer use over four years predicts more severe symptoms of anxiety over that same time frame. Over and above a potential common vulnerability to both sets of behaviors, the study demonstrates that if a teen experienced an increase in their social media use, television viewing and computer use in a given year which surpassed their overall average level of use, then his or her anxiety symptoms also increased in that same year. Furthermore, when adolescents decreased their social media use, television viewing, and computer use, their symptoms of anxiety became less severe. Thus, no lasting effects were found.

Must confess that I never expected to be posting about this. Usually I post about my own experiences, however, I ran across this study and my curiosity got the best of me. I have heard and read about sexting, but that’s as far as it goes.
Wikipedia says, “Sexting is sending, receiving, or forwarding sexually explicit messages, photographs, or images, primarily between mobile phones, of oneself to others. It may also include the use of a computer or any digital device. The term was first popularized early in the 21st century and is a portmanteau of sex and texting, where the latter is meant in the wide sense of sending a text possibly with images. In August 2012, the word sexting was listed for the first time in Merriam-Webster’s Collegiate Dictionary.”
A new analysis from the Texas Tech University Department of Psychological Sciences shows three different, equally prevalent purposes behind sexually based messages
In an analysis of the reasons people engage in sexting with their relationship partner, assistant professor Joseph M. Currin and doctoral student Kassidy Cox confirmed three main motivations found in previous research:
Getting the recommended seven to eight hours of sleep every night is a struggle for most people, but even those who do may not have the best sleep.
New research from Iowa State University finds more Americans have trouble falling asleep and staying asleep. The changes were independent of sleep duration, and difficulties were most prevalent in people with healthy sleep length, the findings show. The study, published in the journal Sleep Health, is one of the first to look at how multiple dimensions of sleep health change over time.
Besides the possibility of your personal information being sent to the dark web by unscrupulous hackers and sold to the highest bidder, it turns out that there are other, more mundane, risks to using social media, according to the Harvard Health Letter.
You’ve mastered the art of texting, emailing, and web surfing on your smartphone and computer. But along with that digital prowess, you’ve picked up an unexpected side effect.
“We get a number of patients who develop injuries from these activities,” says Dr. Tamara Rozental, an orthopedic surgeon who specializes in hand, wrist, and elbow disorders at Harvard-affiliated Beth Israel Deaconess Medical Center.
The repetitive motions of texting and typing can lead to general hand pain from underlying osteoarthritis (the wearing away of cartilage in the joints). “Using these gadgets doesn’t cause osteoarthritis, but if you’re prone to it, it can increase your symptoms,” Dr. Rozental says.

The times they are a’changin’ according to Bob Dylan. And, not always for the better, it seems. I must confess that, as an old man whose eyes ain’t what they used to be, I like the idea of making the print bigger on my screen when reading. I read my Wall Street Journal on a tablet and any books I can, so I like my screens.
Almost half of young children now have their own tablet, a new report says.
According to the report, which comes from Common Sense Media, those tablets are seeing plenty of use. Kids younger than eight are reportedly spending an average of two hours and 19 minutes per day glued to screens. Roughly 30 percent of that time is spent on mobile devices such as tablets and smartphones. Forty-two percent of youngsters have a personal tablet.
While screen use has held fairly steady over time—kids in 2011 spent two hours and 16 minutes per day looking at screens, for example—the medium of choice has changed dramatically, according to the Common Sense Census. Television is still the most popular screen, but daily time spent watching the tube has dropped by 11 minutes since 2011. During the same time period, meanwhile, mobile device use has exploded from five minutes per day to its…
Standing tall doesn’t just make you look better, it optimizes your health, too. Other studies have found good posture elevates testosterone and serotonin in the body, and also reduces levels of the stress hormone cortisol. Good posture has even been linked to personality traits such as tolerance for risk-taking.
Humans were designed to stand upright. And yet in this modern world, too many of us spend our days with our heads slumped over for a simple reason: we’re staring at the tiny screen of a smartphone.
People spend an average of 2 to 4 hours each day with their neck bent at this unnatural angle while shooting off emails or texts. That’s 700 to 1,400 hours a year. The success of social media is has led to an epidemic of bad smartphone posture.
The average adult head weighs 10 to 12 pounds when it’s in the upright or neutral position. However, because of that pesky thing called physics — gravitational pull — the cranium becomes heavier the more you bend your neck. Several times heavier, according to research from Dr. Kenneth Hansraj, chief of spine surgery at New York Spine Surgery and Rehabilitation Medicine, which will be published in…
