Parents, take note! A recent study has highly recommended reduced screen time for the well being of kids.

According to the findings of the San Diego State University, too much time spent on gaming, smartphones and watching television is associated with heightened levels and diagnoses of anxiety or depression in children as young as age two.

The study has been published in the journal Preventive Medicine Reports.

Even after only one hour of screen time daily, children and teens may begin to have less curiosity, lower self-control, less emotional stability and a greater inability to finish tasks, stated researchers Jean Twenge and W. Keith Campbell.

Twenge and Campbell were particularly interested in associations between screen time and diagnoses of anxiety and depression in youth, which has not yet been studied in great detail.

Their findings provided broader insights at a time when youth have greater access to digital technologies and are spending more time using electronic technology purely for entertainment, and also as health officials are trying to identify best practices for managing technology addiction.

“Previous research on associations between screen time and psychological well-being among children and adolescents has been conflicting, leading some researchers to question the limits on screen time suggested by physician organizations,” Twenge and Campbell wrote in their paper.

Twenge and Campbell found that adolescents who spend more than seven hours a day on screens were twice as likely as those spending one hour to have been diagnosed with anxiety or depression – a significant finding. Overall, links between screen time and well-being were larger among adolescents than among young children.

“At first, I was surprised that the associations were larger for adolescents,” Twenge said. “However, teens spend more time on their phones and on social media, and we know from other research that these activities are more strongly linked to low well-being than watching television and videos, which is most of younger children’s screen time.”

Among other highlights of Twenge and Campbell’s study:

-Moderate use of screens, at four hours each day, was also associated with lower psychological well-being than use of one hour a day.

-Among preschoolers, high users of screens were twice as likely to often lose their temper and 46% more likely to not be able to calm down when excited.

-Among teens aged 14-17, 42.2% of those who spent more than seven hours a day on screens did not finish tasks compared with 16.6% for those who spent one hour daily and 27.7% for those engaged for four hours of screen time.

-About 9 per cent of youth aged 11-13 who spent an hour with screens daily were not curious or interested in learning new things, compared with 13.8% who spent four hours on screen and 22.6% who spent more than seven hours with screens.

“Thus, there is an acute need to identify factors linked to mental health issues that are amenable to intervention in this population, as most antecedents are difficult or impossible to influence,” they continued. “Compared to these more intractable antecedents of mental health, how children and adolescents spend their leisure time is more amenable to change.”

Can Diabetics Eat Rice And Potatoes? Top Diabetologist Answers

The Kashmir Monitor

Published

on

Diabetes is not a battle in which we have to fight with ourselves and let win the part which makes us unhappy. It is a part of our life which we should enjoy by balancing our lifestyle. One part of enjoyment is through food, which is a very important game to play what to eat and how much to eat. If we talk about our Indian diet, the staple diet is carbohydrate based, which is rice, wheat, potatoes or sweet potatoes. These are the major sources of carbohydrate in our diet.

How to balance these important sources which gives us satiety?

As per guidelines accepted by most of the associations (FDA, ICMR, ADA, WHO, USDA), carbohydrate should be included in our major meals (Breakfast, Lunch & Dinner).

In each major meal, one- fourth of our plate should contain carbohydrate which comes from rice/roti/potato/sweet potato. The carbohydrate requirement is different for different individuals who are guided by a nutritionist depending on their Basal Metabolic Rate (BMR) and lifestyle.

Why we should consider portion size and follow food plate?

To understand the answer of above question we should know what glycemic index (GI) is and glycemic load. Glycemic index is a score given to different food item which indicates the effect of a carbohydrate rich food to raise our blood glucose level. It is scored between 0-100 which is categorized into 3 categories a. High (70 & above) b. Medium (56 to 69) and c. Low (55 & less). We should prefer taking low GI food. In today’s scenario, not only glycemic index of food is seen but glycemic load of a particular food is taken into consideration for example potato has high glycemic index but low glycemic load.

Glycemic load is to quantify the overall glycemic effect of a portion of food. The higher the glycemic index and glycemic load, higher will be the capacity of the food to elevate blood sugar level. One should know the glycemic index, glycemic load and carbohydrate content in our staple food sources. The table provides this information in 100g of these food items.

The glycemic index of our major carbohydrate sources is high but the glycemic loads of these food items are not high considering the portion size. Also, if we add fibre sources (Vegetables & fruits) it decreases the rapid digestion of glucose.

It is important to understand the quantity and quality of food that can be consumed as there are numerous myths related to diet in diabetes.

Obesity may cause depression even in absence of health issues

Overweight and obese people may be at increased risk of depression, even in the absence of other health problems, warns new research.

The research, published in the International Journal of Epidemiology, showed that the psychological impact of being overweight causes depression, rather than associated illnesses such as diabetes.

“Our research shows that being overweight doesn’t just increase the risks of chronic diseases such as cancer and cardiovascular disease; it can also lead to depression,” said study co-author Elina Hypponen, Professor at the University of South Australia.

For the study, the researchers looked at UK Biobank data from more than 48,000 people with depression, comparing them with a control group of more than 290,000 people born between 1938 and 1971, who provided medical and genetic information.

Hospital data and self-reporting were used to determine whether people had depression.

The team used a genetic research approach to explore the causal link between the two conditions.

They separated out the psychological component of obesity from the impact of obesity related health problems, using genes associated with higher BMI but lower risk of diseases like diabetes.

“These genes were just as strongly associated with depression as those genes associated with higher BMI and diabetes. This suggests that being overweight causes depression both with and without related health issues – particularly in women,” Hypponen said.

“Our robust genetic analysis concludes that the psychological impact of being obese is likely to cause depression. This is important to help target efforts to reduce depression, which makes it much harder for people to adopt healthy lifestyle habits,” said Jess Tyrrell of the University of Exeter Medical School in Britain.

Why music is used as a potential sleep aid?

Published

Besides its potential to help reduce anxiety as well as the negative effects of physical pain, a new study suggests that music might serve as a cheap, non-pharmaceutical sleep aid for people facing difficulty in getting proper sleep. Sleep loss is a widespread problem and poses serious physical and economic consequences. However, there is a lack of systematic data on how widely it is used, why people opt for music as a sleep aid, or what music works.

The study found that music both stimulates sleep and blocks an internal or external stimulus that would otherwise disrupt sleep. “The study offers new understanding into the complex motivations that drive people to reach for music as a sleep aid and the reasons why so many find it effective,” said researchers including Tabitha Trahan from the University of Sheffield in the UK.

Further, to understand why people opt for music as a sleep aid, or what music works, the team investigated music as a sleep aid within the general public via an online survey that scored musicality, sleep habits, and open-text responses on what music helps sleep and why.

They examined 651 adults, who provided new evidence into the relationship between music and sleep in a population that ranged widely in age, musicality, sleep habits and stress levels. The results, published in the journal PLOS ONE, showed that 62 per cent use music to help them sleep. Even those who do not suffer from sleep disorders use music in their everyday lives to help improve the quality of their sleep experiences.

Studies have shown that music has many promising neurological and physiological effects that may be indicative of its effective use in the fight against sleep loss.
The subjective psychological benefits of music have also been linked to chemical changes observed via hormone levels as music increased oxytocin and accordingly levels of relaxation as well as decrease negative thoughts, the study noted.
