Middle-class kids ‘likelier to be obese than poorer counterparts’

Friday, February 15th, 2013

Middle-class children are more likely to be obese than those from poor families, according to new research.

Researchers say the new findings contradict the conventional ”deprivation theory” which suggests childhood weight problems are linked to poverty.

By charting youngsters” obesity levels and where they lived, the team at Leeds Metropolitan University found that those in ”middle-affluent” areas of Leeds were more likely to be very overweight than those in very poor or very wealthy postcode areas, the Daily Mail reported.

The trend was particularly high among girls.

Claire Griffiths, who led the study of 13,333 schoolchildren over three years, concluded that children living in the most deprived and most affluent areas of the city are at the lowest risk.

Losing hope of good night’s sleep may lead to suicide

Friday, February 15th, 2013

When people lose hope that they will ever get another good night’s sleep, they become at high risk for suicide, according to researchers.

Insomnia and nightmares, which are often confused and may go hand-in-hand, are known risk factors for suicide but just how they contribute was unknown, said Dr. W. Vaughn McCall, Chair of the Medical College of Georgia Department of Psychiatry and Health Behavior at Georgia Regents University.

The new study reaffirms that link and adds the element of hopelessness about sleep that is independent of other types of hopelessness, such as those regarding personal relationships and careers, said McCall, corresponding author of the study.

“It turns out insomnia can lead to a very specific type of hopelessness and hopelessness by itself is a powerful predictor of suicide,” he said.

Indian neem tree could hold promise for cancer patients

Friday, February 15th, 2013

Neem tree, which has been used for centuries to treat inflammation, fever and malaria in India, could help kill cancer cells, according to scientists at the Georgia Regents University Cancer Center.

Cancer cells typically avoid death by hijacking molecular chaperones that guide and protect the proteins that ensure normal cellular function and then tricking them into helping mutated versions of those proteins stay alive, said Dr. Ahmed Chadli, a researcher in the Molecular Chaperone Program at the GRU Cancer Center and senior author of the study.

Drug development has focused on the chaperone Hsp90 (heat shock protein 90) because it plays a key role in assisting mutated proteins, making it an attractive cancer drug target.

However, the clinical efficacy of Hsp90 inhibitors has been disappointing. Most current small molecules targeting Hsp90 have inadvertently resulted in the expression of proteins that protect cancer cells from programmed cell death and compromise the Hsp90 inhibitors in the clinic.

Vitamin C halves incidence of common cold

Friday, February 15th, 2013

Vitamin C is beneficial against common cold particularly for people under heavy physical stress.

In five randomized trials of participants with heavy short-term physical stress, vitamin C halved the incidence of the common cold.

Three of the trials studied marathon runners, one studied Swiss school children in a skiing camp and one studied Canadian soldiers during a winter exercise.

Furthermore, in a recent randomized trial carried out with adolescent competitive swimmers, vitamin C halved the duration of colds in males, although the vitamin had no effect on females.

Regular doses of vitamin C of one gram per day or higher have reduced the average duration of colds in adults by 8 percent and in children by 18 percent.

Although these findings unambiguously show that vitamin C has a biological effect on colds, taking vitamin C every day to shorten infrequent colds does not seem reasonable. On average, adults have only a few common cold episodes per year and children have some half a dozen colds per year.

How mindfulness meditation prevents depression and cuts chronic pain distress

Friday, February 15th, 2013

Brown University scientists have shed light on why does training in mindfulness meditation help patients manage chronic pain and depression.

In a newly published neurophysiological review, the scientists have proposed that mindfulness practitioners gain enhanced control over sensory cortical alpha rhythms that help regulate how the brain processes and filters sensations, including pain, and memories such as depressive cognitions.

The proposal, based on published experimental results and a validated computer simulation of neural networks, derives its mechanistic framework from the intimate connection in mindfulness between mind and body, since standardized mindfulness meditation training begins with a highly localized focus on body and breath sensations.

This repeated localized sensory focus, the scientists said, enhances control over localized alpha rhythms in the primary somatosensory cortex where sensations from different body are “mapped” by the brain.

Hi,
I am student in university and I want to lose weight, currently 76kg and I am 20 years old. I don’t cook often but eat readymade meals or pizza, fish finger, chips or chicken fillets.
Thanks

Hi Chandar Lal,
Thank you for writing to me,
You have mentioned that you eat a lot of junk food, pizzas, burgers etc- i understand that you are away from home, but unless you make some radical changes in your diet, this problem will persist, Please try and have healthier food such as the local cuisine , fresh fruit , yoghurt( dahi,0 plenty of water, i cannot tell a 20 year old to stop fast food all together, but have it as a treat once a week, if you follow a healthy diet the other days of the week. You also need to start some physical activity, i suggest a 20 minute walk atleast 5 days a week to begin with.
i hope this helps you, yours in fitness- sonali
