1 hour of watching TV shortens your life by 22 mins


Sitting on the couch and staring at the idiot box could be taking years off your life - 4.8 years to be exact, scientists have warned.
Australian researchers have found that for every hour of television viewed by a person over the age of 25, their life expectancy is reduced by 22 minutes, News.com.au reported.
The study was based on an average six hours viewing per day, compared to a person who watches no television.
Using data from the National Bureau of Statistics and the Australian Diabetes, Obesity and Lifestyle Study, the researchers generated life-expectancy tables based on the viewing habits of average Australians.
The results were alarming.
“TV viewing time may be associated with a loss of life that is comparable to other major chronic disease risk factors such as physical inactivity, smoking and obesity,” the study found.
“These findings suggest that substantial loss of life may be associated with prolonged TV viewing time among Australian adults.”
The research also revealed that in 2008, Australians aged 25 and older watched a total of 9.8 billion hours of TV that year alone.
Recent studies in the US also concluded that the average American spent 35.5 hours a week watching TV.
The study is the first of it’s kind to analyse the impact of television viewing on life expectancy, and has called for a public health case to warn adults of the risks of watching too much television.

About 10 per cent of Delhi’s population suffer from mental illnesses: Study


The Capital is seeing a rise in the number of people suffering from mental health problems, particularly suicidal tendencies, even among the economically weaker sections, doctors said.
On World Mental Health Day, they said the city needed more psychiatrists to address the issue.
Dr Nimesh Desai, Director of Institute of Human Behaviour and Allied Sciences (IHBAS), said: “In Delhi, 8-10 per cent of the population suffers from some form of diagnosed mental illness. This includes depression, anxiety disorders, bipolar disorders, alcoholism and phobias, among others.”
He said 50 per cent of patients suffer from depression. “Of the patients diagnosed with depression in Delhi, around 10-15 per cent are likely to commit suicide at some point, while 40-50 per cent attempt suicide,” Desai said.
A community-based study, conducted by the Indian Council of Medical Research (ICMR) in the city, to assess suicidal behaviour from 2004-2010, found a life-long prevalence of possible suicidal tendencies in 11.1 per cent of the population.
“What’s more surprising is that more than one third of them have no previous history of psychiatric disorders. Almost 40 per cent of suicidal thoughts are not associated with any psychiatric disorders — unlike the belief common among mental health practitioners and the public,” Desai said.
This, experts said, indicates the role of other risk factors like “stress of daily living, including issues related to urbanisation and other social changes.”
The study was spread over 11 colonies of different socio-economic strata. Data was collected from 100 households in each colony.
Two colonies were from South Delhi — Sriniwaspuri and Gautam Nagar. Two were unauthorised colonies from East Delhi with middle income groups — Pandav Nagar and Ganesh Nagar.
Two colonies were from Walled City with low- and middle-income groups — Nai Sarak and Jama Masjid. One was a slum colony from East Delhi with a low-income group and two were from Southwest Delhi with middle-income group — Vikaspuri and Hari Nagar.
Shalimar Bagh from North Delhi with a middle- and upper-income group population and Pitampura from Northwest Delhi with a middle- and higher-income group population were the other colonies studied.
According to government estimates, Delhi has only 250-odd psychiatrists, against an estimated requirement of at least one lakh.
In another three-state ICMR study from 2004-09, spread over a sample size of 10,600 people in Delhi, Lucknow and Chennai, doctors found that between 77-82 per cent of patients with diagnosed mental health problem, who needed clinical help, do not seek treatment.
“There is a problem of shortage of specialists and there is a total lack of awareness. The study found that, among the urban poor, the treatment gap is because of a lack of awareness about their affliction as a health problem and the availability of mental health services,” Desai said.
IBHAS to train docs to handle psychiatric cases
There are only 3,500-odd registered psychiatrists in the country, against of an estimated requirement of 6 lakh. To address the problem, IHBAS, together with ICMR and the Indian Medical Association (IMA), has prepared an 18-hour module for training around 4 lakh general practitioners to treat basic mental health problems. Experts feel this resource pool can play a huge role in addressing the rising number of mental health cases. The first batch of doctors is expected to be trained from Delhi soon.

Depression a key cause for suicides


The underlying cause of 70 per cent of suicides is depression. For every suicide, around ten more attempted suicides would have occurred.
M. Chandrasekharan Nair, city-based psychiatrist, speaking to The Hindu, said that a government directive on treating a patient jointly by a general physician and a psychiatrist for every attempted suicide case could perhaps help in detecting depression and bringing down cases of suicides.
The stigma of getting treated by a psychiatrist continues to be the hurdle in people reaching out for support and care for better mental health, said Dr. Nair.
Depression is a worldwide phenomenon and about 30 per cent of patients reaching for primary care and specialty care have this problem, he said. However, the patients never realise it nor are the treating physicians oriented towards understanding depression in patients.
Intervention at the right time can help morbidity and mortality of attempted suicides.
The attempt is actually a call for help which goes unnoticed, Dr. Nair said.
There are various socially accepted reasons that people attach for suicides — like failure in examinations or broken relationships. Depression hides behind a mask of bodily symptoms like abdominal pain or other body pains and when investigated they reveal nothing, he said.
He said that it is purely lack of awareness on the part of the primary care physician that depression goes undetected at these stages.
The Indian Psychiatric Association had been asking the Medical Council of India to include an examination paper in psychiatry in the MBBS curriculum, said the president of the Association, Roy Abraham Kallivayalil.
The World Health Organisation has said that the treatment of mental health should begin at primary care, he said. Unfortunately, the primary care physicians are not trained to recognise such symptoms, he added.
Depression is a disease that can be treated, said Dr. Nair. Expression of depression comes through the brain. Recognising it early and treating it would help prevent suicides.
