New studies show how obesity amplifies long-term COVID risks and why the effect of smoking might be limited to memory problems, providing new insights into post-COVID fitness challenges.
In an article recently published in the journal Frontiers in Medicine, Spanish researchers investigated the effects of smoking and obesity on the sequelae and threat of hospitalization following coronavirus disease 2019 (COVID-19).
The COVID-19 pandemic has had a significant effect on fitness formulas globally. It basically affects the respiratory formula and its symptoms appear within one or two weeks. Additionally, there are concerns about lingering symptoms that persist for weeks or months afterwards. the initial diagnosis of COVID-19, a phenomenon known as long COVID. These symptoms can last for years, with some patients experiencing persistent consequences on their physical condition more than two years after diagnosis.
Prolonged symptoms of COVID include, yet are not limited to, fatigue, difficulty concentrating, reminiscence loss, loss of smell/taste, and headaches. Obesity has been thought of as a threat thing for serious results from COVID-19. Likewise, smoking is a meaningful threat thing for breathing diseases, adding COVID-19. However, there is little evidence on the have an effect on of obesity and smoking on the progression of extended COVID symptoms and related threats.
In the existing Array the researchers verified the effects of smoking and obesity on post-COVID-19 sequelae and the threat of hospitalization. The population included patients with COVID-19 proven by polymerase chain reaction (PCR) testing in November 2020 in the Castilla y León region of Spain. Eligible participants were former or current smokers and Americans who were overweight or obese (body mass index > 25 kg/m2).
Additionally, an organization was established that aggregates non-smoking and non-obese/overweight people. Information on the threat of hospitalization within 12 months of COVID-19 diagnosis was also required to be included. People with a history of chronic conditions, such as dyslipidemia, hypertension or diabetes, prior to COVID-19.
The researchers obtained data on participants’ age, gender, cardiovascular disease status, long COVID sequelae, memory loss, memory disorders, chronic conditions, and hospitalization. Women represented a higher proportion of participants in all groups: 59.9% of the obesity group, 56.3% of the smoking group, and 54.3% of the control group. Descriptive statistics were used to characterize the sample. Odds ratios were calculated to examine the relationship of obesity and smoking with post-COVID-19 sequelae, cardiovascular disease, chronic conditions (hypertension, dyslipidemia, and diabetes), and hospitalization risk.
In total, the smoking, obese and obese teams included 918, 1,285 and 14,216 subjects, with a mean age of 42. 6, 34. 3 and 36. 3 years, respectively. The most common sequelae after COVID-19 infection were cough, myalgia, headache, taste/smell alterations and fatigue, observed in 1. 34% of smokers, 3. 42% of obese people and 1. 8% of smokers.
Memory disorders occurred in 0. 98% of smokers, 1. 1% of obese patients, and 0. 42% of controls. In addition, there is no statistically significant correlation between the prestige of obesity and the presence of chronic diseases or between smoking history and the presence of post-COVID-19 sequelae. On the other hand, there is a significant correlation between obesity and post-COVID-19 sequelae.
Furthermore, the team identified potential interactions between smoking and obesity in the development of post-COVID-19 sequelae, suggesting that patients with a history of smoking and obesity may have a higher risk of these sequelae. A significant association was observed between smoking history and memory disorders, indicating that patients who smoke may be at a greater risk of experiencing memory disorders post-COVID-19.
Similarly, there is significant agreement between obesity and reminiscence impairment, suggesting that obesity would possibly increase the threat of reminiscence impairment after COVID-19. Notably, there is no significant interaction between smoking, impaired reminiscence and obesity, suggesting that they were independent of each other. Additionally, the researchers did not discover a significant relationship between obesity and the threat of hospitalization.
A comparative study between obese patients and smokers showed a higher risk of long-term COVID sequelae in overweight or obese people than in smokers. The odds ratio study found that obese patients were 1. 9 times more likely to develop long COVID sequelae than non-obese patients. patients and had a 1. 11 times higher risk of memory impairment than smokers. Furthermore, smoking and obese patients had an approximately 2. 65 and 2. 38 times higher risk of memory impairment and memory loss, respectively, than non-smoking and non-obese patients.
Taken together, 1.9% of the cohort presented cardiovascular sequelae, and 1.31% showed long COVID sequelae. The findings suggest that smokers had no higher risk of long COVID sequelae than non-smokers, challenging prior studies suggesting a link between smoking and long COVID. Notably, obese patients had a higher risk of experiencing long COVID symptoms. However, contrary to previous findings, obesity did not increase the risk of hospitalization within 12 months post-COVID-19.
