London, Sep 14: Adhering to a diet rich in fruits, vegetables, whole grain bread, nuts, olive oil and canola oil may help you live longer, a new study has found.

The findings, published in the Journal of Internal Medicine, suggest that those who closely follow an anti-inflammatory diet have an 18 per cent lower risk of all-cause mortality.

The researchers also found that those who follow the diet experience a 20 per cent lower risk of cardiovascular mortality, and a 13 per cent lower risk of cancer mortality, when compared with those who followed the diet to a lesser degree.

“Our dose-response analysis showed that even partial adherence to the anti-inflammatory diet may provide a health benefit,” said lead author Joanna Kaluza, Associate Professor at the Warsaw University of Life Sciences in Poland.

It was also found that smokers who followed the diet experienced even greater benefits when compared with smokers who did not follow the diet, the team said.

For the study, the research team involved 68,273 Swedish men and women aged between 45 and 83 years. The participants were followed for 16 years.

The anti-inflammatory potential of the diet was estimated using the validated anti-inflammatory diet index (AIDI), which includes 11 potential anti-inflammatory and five potential pro-inflammatory foods.

Anti-inflammatory foods consist of fruits and vegetables, tea, coffee, whole grain bread, breakfast cereal, low-fat cheese, olive oil and canola oil, nuts, chocolate, and moderate amounts of red wine and beer.

Pro-inflammatory foods include unprocessed and processed red meat, organ meats, chips, and soft-drink beverages, the team said.

Air pollution cuts average Indian’s life expectancy by over 4 years: Study

Concentrations in Indian states of Bihar, Uttar Pradesh, Haryana, Punjab, and the National Capital Territory of Delhi are substantially higher, and the impact on life expectancy exceeds six years.

Air Pollution in India

New Delhi, Nov 19 : India is the world’s second most polluted country, slightly trailing only Nepal, the Energy Policy Institute at the University of Chicago (EPIC) said on Monday.

Particulate pollution is so severe that it shortens the average Indian’s life expectancy by more than four years relative to what it would be if World Health Organization (WHO) air quality guidelines were met.

This is up from about two years in the late 1990s due to a 69 per cent increase in particulate pollution, it said.

Concentrations in Indian states of Bihar, Uttar Pradesh, Haryana, Punjab, and the National Capital Territory of Delhi are substantially higher, and the impact on life expectancy exceeds six years.

Its new air pollution index, known as the Air Quality Life Index (AQLI), finds that air pollution reduces global life expectancy by nearly two years, making it the single greatest threat to human health.

The tool gives figures like — for an average resident of Delhi, gain in life expectancy if the WHO guidelines are met, could be up to 10.2 years.

Likewise, it gives numbers of years lost to pollution for every district of India for a span of 18 years between 1998 and 2016.

What makes AQLI unique is that it converts pollution into perhaps the most important metric that exists — life expectancy. It does so at a hyper-local level throughout the world.

Further, it illustrates how air pollution policies can increase life expectancy when they meet the World Health Organization’s (WHO) guideline, existing national air quality standards, or user-defined air quality levels.

This information helps informing local communities and policymakers about the importance of air pollution policies in very concrete terms.

Loss of life expectancy is highest in Asia, exceeding six years in many parts of India and China; some residents of the US still lose up to a year of life from pollution.

Fossil fuel-driven particulate air pollution cuts global average life expectancy by 1.8 years per person, according to the pollution index and accompanying report produced by the EPIC.

“Around the world today, people are breathing air that represents a serious risk to their health. But the way this risk is communicated is very often opaque and confusing, translating air pollution concentrations into colors, like red, brown, orange, and green. What those colors mean for people’s wellbeing has always been unclear,” Michael Greenstone, the Milton Friedman Professor in Economics and Director of the EPIC, said.

Greenstone also noted: “My colleagues and I developed the AQLI, where the ‘L’ stands for ‘life’ to address these shortcomings. It takes particulate air pollution concentrations and converts them into perhaps the most important metric that exists, life expectancy.”

The AQLI is based on a pair of peer-reviewed studies co-authored by Greenstone that quantify the causal relationship between long-term human exposure to particulate pollution and life expectancy.

The results from these studies are then combined with hyper-localised, global particulate matter measurements, yielding unprecedented insight into the true cost of air pollution in communities around the world.

Seventy-five per cent of the global population, or 5.5 billion people, live in areas where particulate pollution exceeds the WHO guideline.

The AQLI reveals that India and China, which make up 36 per cent of the world’s population, account for 73 per cent of all years of life lost due to particulate pollution.

On average, people in India would live 4.3 years longer if their country met the WHO guideline, expanding the average life expectancy at birth there from 69 to 73 years.

In the US, about a third of the population lives in areas not in compliance with the WHO guideline.

Those living in the country’s most polluted counties could expect to live up to one year longer if pollution met the WHO guideline.

Globally, the AQLI reveals that particulate pollution reduces average life expectancy by 1.8 years, making it the greatest global threat to human health.

By comparison, first-hand cigarette smoke leads to a reduction in global average life expectancy of about 1.6 years.

Other risks to human health have even smaller effects: alcohol and drugs reduce life expectancy by 11 months; unsafe water and sanitation take off seven months; and HIV/AIDS four months.

Conflict and terrorism take off 22 days. So, the impact of particulate pollution on life expectancy is comparable to that of smoking, twice that of alcohol and drug use, three times that of unsafe water, five times that of HIV/AIDS, and more than 25 times that of conflict and terrorism.

“While people can stop smoking and take steps to protect themselves from diseases, there is little they can individually do to protect themselves from the air they breathe,” Greenstone said.

AIIMS launches research project on air pollution’s impact on health

delhi air pollution

New Delhi, Nov 19: As the National Capital Region (NCR) battles poor air quality during winter, the All India Institute of Medical Sciences (AIIMS) has started a research project to study the effects of air pollution on public health.

“Delhi’s air quality deteriorates every year during Diwali owing to multiple reasons like stubble burning and bursting of crackers. However, last year, when the air pollution level escalated, we noticed a surge in patients visiting AIIMS,” Dr Karan Madan, Associate Professor, Department of Pulmonary Medicine and Sleep Disorders, AIIMS, who is part of this research programme, told IANS.

So the country’s premier medical research and referral hospital decided to conduct empirical research on the impact of air pollution on health.

For the study, titled “DAPHNE” (Delhi Air Pollution Health And Effects), AIIMS researchers have developed an air pollution sensor technology.

“This sort of study has not been earlier conducted in India. The device has been developed in a belt format which is very light and it gives clear continuous pollution data. The belt can be wrapped around the waist or on the arms,” Madan said.

He explained that the device is wireless and directly sends data to a monitoring system through a Global Positioning System (GPS). AIIMS is primarily focusing on children suffering from pulmonary diseases like asthma, bronchitis and other breathing troubles — as well as pregnant women.

The device, which is to be worn by children suffering from asthma or bronchitis, will give an idea of the exposure level of air pollution when one is travelling in the school bus, at home, when in school, or outdoors while playing.

“On pregnant women, we are trying to see how pollution might affect the unborn child. We are also trying to figure out the birth rate issue from this study owing to poor air quality,” Madan noted.

Funded by the Department of Biotechnology, Ministry of Science and Technology, and Medical Research Council, Britain, the project is a collaborative effort of the the two nations.

In India, apart from AIIMS, Sri Ramachandra University, Chennai, IIT Delhi and GTB Hospital are also associated with the research.

“While the data on asthma in children will be compiled at AIIMS, GTB Hospital will be following the cases of pregnant women,” Madan said.

The research process, initiated last year, began on a pilot basis two months ago. Dr Madan stated that around 10 children have been given this belt across Delhi NCR.

“So far, the project is going good and the readings have come accurate. The study will conclude next year and the report will be released,” he added.

Talking about the rise in health hazards among residents in the National Capital Region and its surrounding areas, Madan said that AIIMS has witnessed an increase of 15-20 per cent in the number of patients with cases of respiratory problems like coughing, heavy breathing, asthma symptoms, and burning sensation in throat and nose.

“People with respiratory problems are increasing. Apart from asthma patients, there were fresh cases who visited AIIMS owing to pollution,” he stated.

New York, Nov 17: People suffering from chronic dry eye disease are likely to have a slow reading rate, according to researchers.

The chronic dry eye is a common disease in which natural tears fail to adequately lubricate the eyes, thus drastically affecting its functioning.

The study found that the condition can slow a person’s reading speed by as much as 10 per cent and can make it difficult to read for more than an average of 30 minutes.

Those with clinically significant dry eye could read fewer words per minute — 32 words per minute less — than those without the condition, who read at the same rate of 272 words per minute.

“We suspected that people with dry eye were mostly unable to sustain good reading performance because their tears cannot re-lubricate their eye surfaces fast enough,” said Esen Akpek, from the Johns Hopkins Wilmer Eye Institute in the US.

For the study, published in the journal Optometry and Vision Science, the team included 186 adults aged 50 or older.

The participants had not used prescription or over the counter eyedrops in the 24 hours before testing.

Importantly, all participants responded to eye discomfort vision quality and environmental contributors to eye complaints, such as wind or smoke.

People who experience frequent dry eye symptoms such as stinging, fluctuating vision and dryness can try over the counter eyedrops, but will do best if they undergo professional testing and diagnosis, said Akpek.
