As little as one hour of exposure to tobacco smoke per week can increase the risk of having respiratory symptoms, such as shortness of breath and a dry cough at night among teenagers, warns a study.
“There is no safe level of second hand smoke exposure,” said lead author of the study Ashley Merianos, Assistant Professor at the University of Cincinnati in the US.
“Even a small amount of exposure can lead to more emergency department visits and health problems for teens. That includes not just respiratory symptoms, but lower overall health,” Merianos said.
The study, published in the journal Pediatrics, involved 7,389 non-smoking US teenagers without asthma.
The findings showed that teenagers exposed to just one hour of second hand smoke per week are 1.5 times more likely to find it harder to exercise and two times more likely to experience wheezing during or after exercise.
They are two times more likely to have a dry cough at night and and 1.5 times more likely to miss school due to illness.
“Healthcare providers or other health professionals can offer counselling to parents and other family members who smoke to help them quit smoking, and parents should be counselled on how to prevent and reduce their adolescent’s second hand smoke exposure,” Merianos said.
“Also, health professionals should educate teens on the dangers associated with tobacco use to prevent initiation,” she added. (IANS)
Facebook-owned Instagram has announced to restrict people under age 18 from viewing posts from celebrity influencers that promote cosmetic surgery and various weight-loss products.
Certain posts will be hidden from users under age 18 while others will be removed from Instagram as well as parent company’s platform Facebook, Instagram’s public policy manager Emma Collins said in a statement on Wednesday.
“We want Instagram to be a positive place for everyone that uses it and this policy is part of our ongoing work to reduce the pressure that people can sometimes feel as a result of social media,” Collins was quoted as saying in a report on cbsnews.com.
Social media users including actress Jameela Jamil have long been criticizing influencers like Kim and Khloe Kardashian and Kylie Jenner for promoting fat-loss products.
“If celebs and influencers were actually honest with us about some of these diet/detox products…” Jamil had tweeted in November last year which went viral.
Instagram will remove posts entirely if it “makes a miraculous claim about certain diet or weight loss products, and is linked to a commercial offer such as a discount code”.
The updated policy is part of Instagram’s work to “reduce the pressure that people can sometimes feel as a result of social media,a said Collins.
Earlier, in an interview with the London Evening Standard, Collins said Instagram worked with external experts to make this change without ruining the spirit of the platform.
“We want Instagram to be a positive place for everyone,” she said.
Several studies in the past have suggested that Instagram may be a contributing factor to eating disorders and depression among teenagers.
A recent study published in the journal Pediatrics showed that children who view unhealthy snack images on social media platforms like Instagram are likely to consume more calories from unhealthy snacks.
“The results are supported by celebrity endorsement data, which show unhealthy food endorsements increase children’s unhealthy food intake, but healthy food endorsements have little or no effect on healthy food intake,” said researcher Anna Coate from the University of Liverpool in Britain.
The study was conducted with the aim of examining the effect of social media marketing of snack foods (healthy and unhealthy), via vloggers’ Instagram pages, on children’s snack intake.
Children in the group that viewed the unhealthy snack images consumed 32 per cent more calories from unhealthy snacks specifically and 26 per cent more calories in total — from healthy and unhealthy snacks — compared with children who saw the non-food images, the findings showed.
The results suggest that the marketing of unhealthy foods, via vloggers’ Instagram pages, increases children’s immediate energy intake. (IANS)
