Poor grades? Blame your genes, scientists say

Houston, Sept 6: Children's ability to score better grades may be encoded in their DNA, say scientists who found that around two-thirds of individual differences in academic achievement can be explained by comparing genes.

For many years, research has linked educational achievement to life trajectories, such as occupational status, health or happiness.

However, researchers from the University of Texas in the US and King's College London in the UK showed that genes have a substantial influence on academic success, from the start of elementary school to the last day of high school.

The study, published in the journal npj Science of Learning, analysed test scores from primary through the end of compulsory education of more than 6,000 pairs of twins.

Researchers found educational achievement to be highly stable throughout schooling, meaning that most students who started off well in primary school continued to do well until graduation.

Genetic factors explained about 70 per cent of this stability, while the twins shared environment contributed to about 25 per cent, and their nonshared environment, such as different friends or teachers, contributed to the remaining five per cent.

"Around two-thirds of individual differences in school achievement are explained by differences in children's DNA," said Margherita Malanchini, a psychology postdoctoral fellow at the University of Texas.

"But less is known about how these factors contribute to an individual's academic success over time," said Malanchini.

However, this does not mean that an individual was simply born smart, researchers explained. Even after accounting for intelligence, genes still explained about 60 per cent of the continuity of academic achievement.

"Academic achievement is driven by a range of cognitive and noncognitive traits," Malanchini said.

"Previously, studies have linked it to personality, behavioural problems, motivation, health and many other factors that are partly heritable," she said.

However, at times grades did change, such as a drop in grades between primary and secondary school. Those changes can be explained largely by non-shared environmental factors, researchers said.

"Our findings should provide additional motivation to identify children in need of interventions as early as possible, as the problems are likely to remain throughout the school years," said Kaili Rimfeld, a postdoctoral researcher at King's College London.

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.

The practice of washing your hands for 20 seconds is one of the best preventive measures you can take to avoid the spread of any virus including coronavirus as recommended by the WHO.

The modern day concept of handwashing was introduced by Hungaraian doctor Ignaz Semmelweis, in 19-th century Vienna. Semmelweis proposed the practice of washing hands with chlorinated lime solutions in 1847 while working in the city's general hospital.

Decades later, in the modern times too the practise has not lost it's relevance. To connect with savvy consumers the message is being sent through social media? But social media can also be a dark place where misinformation is rampant; consumers can end up being misguided and compromised on sensitive issues like health and hygiene.

Dettol, recently kickstarted its #HandWashChallenge on TikTok aiming to raise awareness on four simple steps of handwashing. Strategically aimed at creating awareness among audience, a unique song has been created pairing it extremely well with the hashtag #HandWashChallenge. The hashtag filter has a branded Dettol strip across the top with the hashtag and names the steps involved in washing hands. The user can dance out the steps to the challenge and share it with their friends to further amplify the message on hygiene and safety.

Commenting on the same, Pankaj Duhan, Chief Marketing Officer, RB Health South Asia said, "We are elated with the response to the #HandWashChallenge, it has definitely become one of the most successfully led initiatives by any of our brands at RB. Understanding the consumer's mindset is of the utmost importance to us, therefore our campaign communication is built in a way that creates meaningful conversations to drive awareness amongst consumers. The participation by TikTok users across India has helped deliver the right message in a more engaging and interactive manner.

"I personally would like to encourage more and more people to join this global health & hygiene educational exercise. Together, let us all build a healthier nation, four steps at a time."

He further said, "Over the past couple of weeks we have witnessed a lot of misinformation floating around hygiene practices, especially over the internet. Realizing the gravity of the issue and being the responsible brand, we felt it was our prerogative to initiate this awareness campaign."

The campaign witnessed several quirky activities on each day leading to increased consumer interest. Joining the force were some of Bollywood's popular celebrities like Kartik Aaryan and Urvashi Rautela among several other TikTok influencers who have millions of followers on the platform. As part of Phase II, Dettol plans to take the challenge global by encouraging more users to participate while the audience worldwide.

The challenge has witnessed over 18 Billion views and generated over 123K user participation videos in one week of starting the campaign.

Europe, Jan 11: Researchers have revealed the people who drink tea at least three times a week have healthy years of life and longer life expectancy.

The research was published in the European Journal of Preventive Cardiology, a journal of the European Society of Cardiology (ESC).

Dr Xinyan Wang, who is the author of the study, said: "Habitual tea consumption is associated with lower risks of cardiovascular disease and all-cause death. The favourable health effects are the most robust for green tea and for long-term habitual tea drinkers."
The analysis that was conducted included about 100,902 participants of the China-PAR project2 with no history of heart attack, stroke, or cancer.

Participants were classified into two groups: Habitual tea drinkers and never or non-habitual tea drinkers and followed-up for a median of 7.3 years.

The analyses estimated that 50-year-old habitual tea drinkers would develop coronary heart disease and stroke 1.41 years later and live 1.26 years longer than those who never or seldom drank tea. Compared with never or non-habitual tea drinkers, the habitual tea consumers had a 20 per cent lower risk of incident heart disease and stroke, 22 per cent lower risk of fatal heart disease and stroke, and 15 per cent decreased risk of all-cause death.

The potential influence of changes in tea drinking behaviour was suspected in a subset of 14,081 participants with assessments at two-time points. The average duration between the two surveys was 8.2 years, and the median follow-up after the second survey was 5.3 years.

Habitual tea drinkers who maintained their habit in both surveys had a 39 per cent lower risk of incident heart disease and stroke, 56 per cent lower risk of fatal heart disease and stroke, and 29 per cent decreased risk of all-cause death compared to consistent never or non-habitual tea drinkers.

Senior author Dr Dongfeng Gu said: "The protective effects of tea were most pronounced among the consistent habitual tea drinking group. Mechanism studies have suggested that the main bioactive compounds in tea, namely polyphenols, are not stored in the body long-term. Thus, frequent tea intake over an extended period may be necessary for the cardioprotective effect."

In a subanalysis by type of tea, drinking green tea was linked with approximately 25 per cent lower risks for incident heart disease and stroke, fatal heart disease and stroke, and all-cause death. However, no significant associations were observed for black tea.
Dr Gu noted that a preference for green tea is unique to East Asia.

Two factors may be at play. First, green tea is a rich source of polyphenols which protect against cardiovascular disease and its risk factors including high blood pressure and dyslipidaemia. Black tea is fully fermented and during this process, polyphenols are oxidised into pigments and may lose their antioxidant effects. Second, black tea is often served with milk, which previous research has shown may counteract the favourable health effects of tea on vascular function.

Gender-specific analyses showed that the protective effects of habitual tea consumption were pronounced and robust across different outcomes for men, but only modest for women. Dr Wang said: "One reason might be that 48 per cent of men were habitual tea consumers compared to just 20 per cent of women. Secondly, women had a much lower incidence of, and mortality from, heart disease and stroke. These differences made it more likely to find statistically significant results among men."

She said: "The China-PAR project is ongoing, and with more person-years of follow-up among women the associations may become more pronounced."

In conclusion, the authors have found that randomised trials are required to validate the results and to illustrate nutritional guidelines and advice for lifestyle.
