The association between prenatal SHS exposure and AD
Although no statistically significant differences were noted in AD diagnosis, symptoms, and current AD between the SHS-exposed and non-exposed groups until 6 years of age, children with prenatal SHS exposure had a significantly higher risk of AD diagnosis (aOR 1.670, 95% CI: 0.995–2.804), symptoms (aOR=1.483, 95%CI: 1.021–2.155), and current AD (aOR=1.823, 95% CI: 1.051–3.161) at school age (7–9 years) (Table 2).
