Finding F-0706

“The odds of previous COVID-19 infection were 1.21 (95% CI: 1.01, 1.51) times higher for those exposed to AN; the odds of self-reported long COVID-19 disease were 3.69 (95% CI: 1.11, 16.6) times higher for those exposed to NO2.”

Structure

Factor
Nicotine
Outcome
COVID-19
Population
members of multigenerational Tribal households
Setting
home, US
Study design
community-engaged cross-sectional study in a Great Plains Tribal community (Cheyenne River Sioux Tribe): 290 multigenerational households, week-long passive monitors for airborne nicotine and nitrogen dioxide, saliva serology for SARS-CoV-2 and a questionnaire on COVID-19 outcomes; multilevel logistic regression grouped by household, adjusted for age, sex, household income and household size (class 4)
Effect
OR 1.21 (1.01–1.51)
Sample
545 participants
Caveat
nitrogen dioxide was not significantly associated with previous infection, and airborne nicotine was not associated with long COVID-19 disease
