Structure

Factor: Formaldehyde (CH₂O)
Outcome: Birth outcomes
Population: pregnant women and their newborns
Setting: home, AU
Study design: birth cohort in Western Australia: formaldehyde, nitrogen dioxide and VOCs monitored in the homes of pregnant women at 34 weeks of gestation, associations with birth outcomes adjusted for maternal age, parity, asthma, diabetes, hypertension and season (class 3)
Effect: beta -0.056 per 1 z-score
Caveat: head circumference has no slug of its own and is filed under birth-outcomes; the same paper reports a significant reduction in birth weight (Table 3, not a closed sentence)
