While the focus of the following research was overseas, the U.S. suffers from obesity and excess body fat to a large extent also.
Obesity and excess body fat may have contributed to more deaths in England and Scotland than smoking since 2014, according to research published in the open access journal BMC Public Health.
Between 2003 and 2017 the percentage of deaths attributable to smoking are calculated to have decreased from 23.1% to 19.4% while deaths attributable to obesity and excess body fat are calculated to have increased from 17.9% to 23.1%. The authors estimate that deaths attributable to obesity and excess body fat overtook those attributable to smoking in 2014.
Jill Pell, at the University of Glasgow, United Kingdom, the corresponding author said: “For several decades smoking has been a major target of public health interventions as it is a leading cause of avoidable deaths. As a result, the prevalence of smoking has fallen in the United Kingdom. At the same time the prevalence of obesity has increased. Our research indicates that, since 2014, obesity and excess body fat may have contributed to more deaths in England and Scotland than smoking.”
You really might call this the – so what else is new – post.
Each cigarette smoked a day by heavier smokers increases the risk of contracting some diseases by more than 30 per cent, according to a new international study published today.
The Australian Centre for Precision Health based at the University of South Australia led the study, which links heavier smoking* with 28 separate health conditions, revealing a 17-fold increase in emphysema, 8-fold increase in atherosclerosis (clogged arteries) and a 6.5-fold higher incidence of lung cancer.
The findings, published in EClinicalMedicine, analysed hospital data and mortality statistics from more than 152,483 ever* smokers in the UK Biobank to look how heavier smoking affects disease risks.
As if smoking weren’t bad enough for you, it seems the new coronavirus likes it, too.
The lungs of people who smoke may contain more of the receptors that the new coronavirus uses to invade cells. This could explain why people with the virus who also smoke appear to be particularly vulnerable to severe illness.
The majority of people who acquire SARS-CoV-2, the virus that causes COVID-19, experience mild-to-moderate symptoms and will fully recover without hospital treatment.
However, several studies suggest that people who smoke are significantly more likely than people who do not to develop a severe form of the illness.
For example, according to a recent study of COVID-19 cases in hospitals in mainland China, 11.8% of people who smoked had a nonsevere form of the disease, while 16.9% had severe disease.
To break into cells and start replicating itself, the virus latches onto a protein receptor called angiotensin-converting enzyme 2 (ACE2), which is present in the cells’ membranes.
As if smoking per se weren’t bad enough, now, it turns out that smoking significantly worsens COVID-19, according to a new analysis by UC San Francisco of the association between smoking and progression of the infectious disease.
In a meta-analysis of studies that included 11,590 COVID patients, researchers found that among people with the virus, the risk of disease progression in those who currently smoke or previously smoked was nearly double that of non-smokers. They also found that when the disease worsens, current or former smokers had more acute or critical conditions or death. Overall, smoking was associated with almost a doubling of the risk of disease progressing.
As regular readers know, I feel strongly that smoking is an unmitigated blight on our lives. We lose over 170,000 people to it every year – just in lung cancer alone – totally preventable. To be honest, I am surprised that anyone who can read would choose to be a smoker. Nonetheless, it is so. I have a Page on it – How many ways does smoking harm you? which I recommend you check out after reading this.
I am reproducing what follows from Medical News Todaybecause I like the way they spell out positive aspects of ceasing smoking. Jenna Fletcher wrote it.
Cigarette smoking is one of the leading causes of preventable death in the United States. Despite this, some smokers find quitting daunting. They think it will take a very long time before seeing improvements in their health and well-being.
However, the timeline for seeing real benefits to quitting smoking is much faster than most people realize. Health benefits begin in as little as an hour after the last cigarette and continue to improve. Continue reading →
