Risks of e-cigarettes to respiratory health

The investigative team conducted a survey University of Southern California and published in the magazine ‘Chest’ The risks of young people consuming e-cigarettes have been shown. Studies have confirmed that people who consume these substances are at greater risk of developing bronchial symptoms or difficulty breathing.

This study shows that substances such as cigarettes or marijuana can cause lung problems whether they smoke or are around smokers.A large percentage of studies analyzed symptoms after using these devices, but not their effects Simultaneous consumption Cigarettes and/or marijuana.

Some 2,097 students (mean age 17 years) completed a survey on tobacco product use and respiratory symptoms in 2014 (first wave). Additional survey information was collected in 2015 (Wave 2), 1,502 in 2017 (Wave 3), and 1,637 in 2018 (Wave 4).

In each survey round, participants were asked about their past and previous 30-day use of e-cigarettes and traditional cigarettes.he marijuana use It was added to the questions for the third round.

Wheezing is defined as wheezing or whistling in the chest within the past 12 months and shortness of breath from running fast on level ground or climbing small inclines

this bronchitis symptoms Defined as daily cough or bronchitis for three consecutive months previous 12 monthsor congestion or phlegm unless accompanied by a cold. Wheeze was defined as wheezing or whistling in the chest within the past 12 months and shortness of breath while running fast on level ground or climbing a small incline.

The final analysis included 2,094 young people, almost half of whom were women. In the first wave, 23% of respondents reported a lifetime history of asthma.

Current wheeze and shortness of breath vary According to cyclebronchial symptoms were the most frequently reported symptoms in each cycle: 19.5%, 22.5%, 23.5%, and 26%, respectively.

this E-cigarette use prevalence Over the past 30 days, this was slightly under 12% for waves 1 and 2, 11% for wave 3, but increased to over 15.5% for wave 4.

They were twice as likely to have bronchial symptoms and 78% more likely to have shortness of breath.

81% more likely to wheeze e-cigarette users The usage rate in the last 30 days is higher than that of users who have never used it. Likewise, taking into account the surge in the number of surveys, the odds of experiencing bronchial symptoms doubled, while the odds of experiencing shortness of breath increased by 78%. thisParents’ age, sex, race, and education.

Additional adjustments used at the same time cigarettes and marijuana Exposure to second-hand vaping, cigarettes and/or marijuana decreased slightly All observed associationsbut still statistically significant except for wheeze.

Estimates of the effects of vaping were slightly stronger for those who had not used potentially affecting cigarettes or marijuana in the past 30 days, the researchers noted.

The association also insists follow-up analysis This excluded those with lifelong asthma, suggesting the observed associations held for all participants, not just those with asthma, the researchers added.

Although the findings of the Experimental Studythis is still an observational study, so firm conclusions about cause and effect cannot be drawn.

“This study adds to new evidence in humans and toxicology studies that e-cigarettes cause respiratory symptoms that warrant consideration in e-cigarette regulation.”

However, research has some restrictions Because, unlike cigarettes, which can be quantified by the number of cigarettes smoked per day, researchers did not have a valid questionnaire-based method to assess smoking frequencyplus vaping products come in many different forms, strengths and flavors, all of which may have played a role in the reported respiratory effects.

“This study adds to new evidence in humans and toxicology studies that e-cigarettes cause respiratory symptoms worthy of consideration in e-cigarette regulation, and suggests that regulatory assessments underestimate the effects of e-cigarettes, marijuana, and tobacco products on late adolescence and effects on young adults. Adults,” the researchers note.

The finding prompted U.S. researchers to call for Respiratory effects Electronic cigarette products are included in the scope of supervision.

The latest estimates in the US suggest that 14% of high school students will still use e-cigarettes by 2022, even though we know that e-cigarette aerosols contain: damage the lungs.
