Finding F-0701

“Higher household NO2 was associated with greater odds of chronic cough (OR 5.51; 95% CI: 2.21, 13.7).”

Unraveling the impact of indoor air pollution on respiratory health in people living with HIV within a high-prevalence HIV cohort (2025). BMC Pulm Med. Page 7. CKB 1096

Structure

Factor: Nitrogen dioxide (NO₂)
Outcome: Respiratory symptoms
Population: persons living with HIV and persons at risk for HIV
Setting: home, US
Study design: Baltimore cohort of persons living with HIV and persons at risk for HIV (SHIELD): 1997 participants with baseline questionnaires and spirometry for reported household exposures, plus a 36-home pilot (SHIELD Home) with weeklong direct measurement of household PM2.5 and NO2; logistic and quantile regression adjusted for age, sex, smoking, race, HIV serostatus and lung function (class 3)
Effect: OR 5.51 (2.21–13.7) per 1 interquartile range of household NO2, 12 ppb
Sample: 36 participants
Caveat: chronic cough is filed under respiratory-symptoms because the register has no cough slug; the pilot has 36 homes, hence the wide interval
