A College of Oxford-led examine hyperlinks a wholesome pre-infection way of life to a 36% decrease danger of lengthy COVID, a 41% decrease odds of demise, and 22% decrease probability of hospitalization.
The researchers assessed the affiliation of modifiable way of life components (eg, smoking, alcohol use, physique mass index, bodily exercise, time spent in sedentary actions, sleep period, weight-reduction plan) with lengthy COVID, demise, and hospitalization amongst 68,896 adults within the UK Biobank cohort who examined optimistic for COVID-19 from March 2020 to March 2022.

71% of advantages attributed to way of life
A complete of 5.5% and seven.8% had long-COVID indicators or signs in a minimum of one studied organ system throughout and after an infection, respectively. A wholesome way of life was tied to a 36% decrease danger of lengthy COVID (absolute danger discount [ARR] at 210 days, 7.1%) in contrast with an unfavorable way of life. And an intermediate way of life was linked to a 20% decrease danger of lengthy COVID, in contrast with an unhealthy way of life (ARR, 3.9%).
