People with allergies such as hay fever, rhinitis, and atopic eczema may be at lower risk of COVID-19 infection, especially if they also have asthma, and a large population-based study of adults in the UK has been put into the respiratory tract. Journals published online rib cage..
And contrary to the findings of recent research senior citizen, Male gender, and other underlying conditions are not associated with an increased risk of infection, studies show.
However, Asian ethnicity, obesity, overcrowding of households, indoor relationships with other households, and curbing the role of dealing with people other than health and social care are all independent of the increased risk of developing COVID-19. The findings show that they are related.
At least some of the ever-increasing evidence Risk factor Researchers say the methods for developing COVID-19 may differ from those that predispose to severe illness and the need for intensive care.
To further investigate this and collect how demographic, socioeconomic, lifestyle, diet, medical care, and underlying disease contribute to the risk of developing COVID-19, researchers 2020 We have collected detailed information on potential risk factors for infection in British adults in May of the year. And February 2021.
All participants received information on age, family status, work, lifestyle, weight, height, long-standing medical conditions, drug use, vaccination status, diet and supplement intake, and when they participated in the study. I was asked to offer it in the following months.
Of the 16,081 eligible individuals, 15,227 completed at least one monthly follow-up questionnaire at least 30 days after participating in the survey. And 14,348 people answered the final questionnaire before February 5, 2021.
The average age of the participants was 59 years. 70% were female. And 95% identified their ethnic origin as white.
In total, 446 participants (almost 3%) experienced at least one confirmed episode of COVID-19 infection, as determined by a swab (PCR or lateral flow) test during the study period. And 32 people were hospitalized.
Researchers have described a set of potentially influential factors. Age: Gender: Period of participation in the study: Ethnicity: Test frequency: Ethnicity. Education; Deprivation; Household income; Housing type; Number of people per bedroom. Home schoolchildren; Pet dog ownership; Shields; Socializing with other households; Visits to shops and other indoor public places. Travel for work or study. The status of frontline workers. Physical activity; Alcohol intake; Body weight (BMI); Asthma; Allergies; Use of immunosuppressive drugs, inhaled corticosteroids, and bronchodilators; BCG vaccination status; Fruit, vegetable, and salad intake. Use of dietary supplements.
The results revealed that certain factors were independently associated with an increased probability of developing COVID-19.
Asian / Asian British people were more than twice as likely to be infected as white people.
Similarly, overcrowding of households. Interact with other households the previous week. Number of visits to indoor public places.The role of facing people other than health Social careOverweight / obesity were all associated with increased risk.
The findings also show that the more people who share a household and the more visits to public places indoors, the more likely they are to get infected.
However, atopic (allergen-induced) diseases, including eczema / dermatitis and hay fever / allergic rhinitis, are independent of the 23% lower chance of developing an infection than patients without atopic or asthma. Was related.
And among people with atopic dermatitis and asthma, the risk was even lower, 38%. This association was true even after considering the use of steroid inhalers.
Taking drugs that suppress the response of the immune system (immunosuppressants) was also associated with a 53% lower odds for COVID-19 infection, which increased protection from infection by these patients. It may reflect what was done.
However, age, gender, other medical conditions, diet, and supplement use were not associated with infection risk.
Since this is an observational study, the cause cannot be determined. And researchers admit that their research has some limitations.
These include reliance on the results of routine tests, which would normally be driven by symptoms, without the monitoring of swab tests, so you may miss the asymptomatic ones. infection..
Participants also participated voluntarily, so some ethnic minorities, especially blacks, Africans, and Caribbeans, were underestimated in the survey.
Nonetheless, the researchers said, “This large population-based prospective study, as reported in the inpatient cohort, is a risk factor for developing COVID-19 and of hospitalization and death in the intensive care unit. It shows that there is limited overlap with risk factors. ”
