TL;DR: Rinitis and wheeze were associated with elevated FeNO in this rural, agricultural population of women and children, and smoke from waste burning as well as para-occupational pesticide exposure may contribute to elevatedFeNO in rural communities. (via Semantic Scholar)

Fractional exhaled nitric oxide (FeNO) is a marker of airway inflammation. Elevated FeNO has been associated with environmental exposures, however, studies from tropical countries are limited. Using data from the Infants' Environmental Health Study (ISA) birth cohort, we evaluated medical conditions and environmental exposures' association with elevated FeNO.
