The researchers used an adapted version of a mood induction task called the Trier-Social Stress Task, intended to cause feelings of stress and anxiety in the subject. During the study, 71 children aged 3 and 8 were asked to tell a short story within 3 minutes. They were told that they would be judged based on how interesting it was.
To analyze children’s speech, scientists used a machine learning algorithm. The algorithm proved to be very successful at diagnosing children.
Study senior author Ryan McGinnis says: “The algorithm was able to identify children with a diagnosis of an internalizing disorder with 80% accuracy, and in most cases that compared really well to the accuracy of the parent checklist.”
A new study from Sweden finds that obesity in youth increases their risk of anxiety and depression.
In the course of study, a team of researchers analyzed data from over 12,000 children and teenagers aged from 6 to 17 who were treated from obesity. These data have been compared with the data from 60,000 kids and teens without obesity.
The scientists concluded in their paper that the girls with obesity were 43 percent more likely to have anxiety or depression compared with their age- and sex-matched counterparts. The risk of anxiety and depression was also 33 percent higher among boys with obesity, compared with their peers without obesity.
A new study by Hiroshima University, Japan, suggests that people who blame themselves when things go wrong are at higher risk of developing obsessive-compulsive disorder (OCD) or generalized anxiety disorder (GAD).
OCD is an anxiety disorder in which people have unwanted and repeated thoughts, feelings, ideas, sensations (obsessions), or behaviors that make them feel driven to do something (compulsions).
GAD is a long-term condition that causes a person to feel anxious about a range of problems, not just one specific issue.
The scientists point out that the study was small but they believe the same results would likely occur with a larger number of participants.
A new Irish study finds that vitamin D deficiency can increase the risk of developing depression by up to 75% in senior people.
The study included data collected from 3,965 people older than 50 years who participated in The Irish Longitudinal Study on Ageing (TILDA). The people were followed for 4 years, and by the end of the study period developed depression. People with a lack of vitamin D demonstrated a 75% higher risk of depression.
One of the researchers Eamon Laird from Trinity College Dublin comments: “Given that vitamin D is safe in the recommended intakes and is relatively cheap, this study adds to the growing evidence on the benefits of vitamin D for health.”
A recent research from the US finds that people who go to bed and wake up early have a lower risk of developing depression.
A team of researchers analyzed the relevant medical data of 32,470 female participants who were aged 55 years on average. In 2009, at the start of the study, all participants were depression-free. In the course of the study, they reported changes in their health in questionnaires after 2 years.
Having analyzed the gathered data, the team concluded that early birds had a 12–27% lower risk of depression than other participants.
Lead study author Céline Vetter says: “Alternatively, when and how much light you get also influences chronotype, and light exposure also influences depression risk. Disentangling the contribution of light patterns and genetics on the link between chronotype and depression risk is an important next step.”
