Feb 14: Chemicals used in food wrappers, non-stick pan coatings and clothing may boost body weight by interfering with metabolism, especially in women, US researchers said Tuesday.

These chemicals -- known as perfluoroalkyl substances (PFASs) -- have previously been linked with cancer, hormone disruption, immune dysfunction, high cholesterol, and obesity.

"Now, for the first time, our findings have revealed a novel pathway through which PFASs might interfere with human body weight regulation and thus contribute to the obesity epidemic," said senior author Qi Sun, assistant professor in the Department of Nutrition at Harvard University T.H. Chan School of Public Health.

Researchers found that PFASs -- also known as "obesogens" because they interfere with body weight regulation -- were linked to a slower resting metabolic rate.

People with higher levels of PFASs in their blood also had more sluggish metabolisms after weight loss. The study tracked data from 621 overweight and obese participants in a clinical trial on weight loss conducted in the mid-2000s.

The study looked at the effects of four heart-healthy diets on weight loss over a period of two years.

Participants also had levels of PFASs in their blood measured.

On average, those in the program lost 14 pounds (6.4 kilograms) in the first six months, but regained six lbs (2.7 kg) over the course of the following year and a half.

"Those who gained the most weight back also had the highest blood concentrations of PFASs, and the link was strongest among women," said the report in the journal PLOS Medicine.

"On average, women who had the highest PFAS blood levels (in the top third) regained 3.7-4.8 lbs (1.7-2.2 kg more body weight than women in the lowest third."

Researchers also discovered that those with higher blood concentrations of PFASs "were significantly associated with lower resting metabolic rates."

PFASs have been have been around for 60 years, and have contaminated drinking water near some industrial sites, military bases, and wastewater treatment plants.

The chemicals can accumulate in drinking water, persist for a long time in the body, and are difficult to avoid.

"We typically think about PFASs in terms of rare health problems like cancer, but it appears they are also playing a role in obesity, a major health problem facing millions around the globe," said study co-author Philippe Grandjean, adjunct professor of environmental health at Harvard Chan School.

"The findings suggest that avoiding or reducing PFAS exposure may help people maintain a stable body weight after they successfully lose some weight, especially for women."

With the sales of chicken and mutton going down due to the coronavirus scare, it is the humble 'Kathal' (jackfruit) is emerging as an acceptable alternative.

'Kathal' is now selling at ₹120 per kilogram -- an increase of more than 120 per cent over the normal ₹50 per kilogram.

The jackfruit, in fact, is now priced higher than chicken which is selling at ₹80 per kilogram due to poor demand.

"It is better having a 'Kathal' biryani instead of a mutton biryani. It tastes reasonably good. The only problem is that 'Kathal' has been sold out in the vegetable market and is difficult to find," said Purnima Srivastava whose family savours non-vegetarian food on a regular basis.

The corona scare has hit poultry business so hard and the Poultry Farm Association recently organized a Chicken Mela in Gorakhpur to dispel the misconception that birds are carriers of the deadly virus.

"In fact, we gave away plateful of chicken dishes for Rs 30 to encourage people to savour the delicacies. We cooked one thousand kilograms of chicken for the Mela and the entire stock was sold out," said Vineet Singh, head of the Poultry Farm Association.

However, the Mela did not do much to dispel the fears about chicken, mutton or fish consumption amid the virus outbreak.

The lockdown forced by the coronavirus in India has had some unexpected but positive fallouts: It has brought families together and reduced corporate politics, says an expert working in the field for the past decade.

"Today the whole world is on lockdown because of COVID-19, and all that we read, talk and hear is about life and death. We can't deny that the times are tough and the future is uncertain. But I would like to turn the coin and see the other side: the positive side," Shikha Mittal, Founder Director of Be.artsy told IANS in an interview.

Be.artsy is one of India's leading social awareness enterprises which deals with emotions at work and promotes arts as a communication tool for workplaces.

"In the 21st century, personally and professionally, people are practising politics over humanity, competition over collaboration, and have lost touch with themselves due to materialistic desires. During the lockdown, we are forced to confront our existing daily lives, and two interesting things that we can ponder upon, have emerged.

"First, have we ever looked at our family with the same lens as we are using today? What is it that we are doing differently with family today, and what can we do to carry our actions of today into our tomorrow? This is the premise of the #aajjaisakalcontest" that Be.artsy has launched across India.

The aim is "to encourage people to share one habit or life skill that they never practiced earlier, but post Covid-19 would like to continue and enjoy".

How did Be.artsy come about?

"I used to be in the corporate world, earning promotions and greater responsibility. However, the work conditions in those days were unfriendly to women and I had faced many instances of sexual harassment and workplace harassment in the six years of my corporate career. And that's when I had an epiphany."

Be.artsy's most popular programmes are on Prevention of Sexual Harassment (POSH) and on Financial Literacy which makes young people financially independent and better prepared to face the corporate world. "We know that a stitch in time (of planning for the future) saves nine (debt trap, dependence, health emergencies, expenses exceeding income, no savings, families without support, retirement in poverty, lost dreams, extravagance). This can only be achieved by sensitisation," Mittal explained.

Toronto, Feb 4: People who text while walking face a higher risk of an accident than those listening to music or talking on the phone, a study has found.

The study, published in the journal Injury Prevention, found that smartphone texting is linked to compromised pedestrian safety, with higher rates of 'near misses', and failure to look left and right before crossing a road.

Researchers from the University of Calgary in Canada call for a more thorough approach to exploring the impact of distracted pedestrian behaviours on crash risk.

Worldwide, around 270,000 pedestrians die every year, accounting for around a fifth of all road traffic deaths, according to the researchers.

'Pedestrian distraction' has become a recognised safety issue as more and more people use their smartphones or hand held devices while walking on the pavement and crossing roads, they said.

The researchers looked for published evidence to gauge the potential impact on road safety of hand-held or hands-free device activities.

This included talking on the phone, text messaging, browsing and listening to music.

From among 33 relevant studies, they pooled the data from 14 -- involving 872 people -- and systematically reviewed the data from another eight.

The analysis showed that listening to music wasn't associated with any heightened risk of potentially harmful pedestrian behaviours.

Talking on the phone was associated with a small increase in the time taken to start crossing the road, and slightly more missed opportunities to cross the road safely.

The researchers found that text messaging emerged as the potentially most harmful behaviour.

It was associated with significantly lower rates of looking left and right before or while crossing the road, and with moderately increased rates of collisions, and close calls with other pedestrians or vehicles, they said.

Texting also affected the time taken to cross a road, and missed opportunities to cross safely, but to a lesser extent, according to the researchers.

The review of the eight observational studies revealed that the percentage of pedestrians who were distracted ranged from 12 to 45 per cent, they said.

It also found behaviours were influenced by several factors, including gender, time of day, solo or group crossing, and walking speed.

The researchers acknowledge "a variety of study quality issues" which limit the generalisability of the findings.

"Given the ubiquity of smartphones, social media, apps, digital video and streaming music, which has infiltrated most aspects of daily life, distracted walking and street cross will be a road safety issue for the foreseeable future," the researchers noted.

"And as signage and public awareness campaigns don't seem to alter pedestrian behaviour, establishing the relationship between distracted walking behaviour and crash risk is an essential research need," they said.
