Finding F-1755

“Exposures associated with LRTI were antenatal maternal smoking (incidence rate ratio 1·62, 95% CI 1·14–2·30; p=0·004) or particulate matter (1·43, 1·06–1·95; p=0·008).”

Structure

Factor: Particulate matter (PM₂.₅ and PM₁₀)
Outcome: Lower respiratory infections (LRI)
Population: infants
Setting: home, ZA
Study design: South African birth cohort: antenatal and postnatal home visits measured indoor air pollutants and maternal smoking by urine cotinine, with lower respiratory tract illness ascertained prospectively through the first year of life (class 3)
Effect: RR 1.43 (1.06–1.95)
Caveat: printed as an incidence rate ratio and recorded under measure RR; sibling row carries antenatal maternal smoking
