Children whose mothers had a dog while they were pregnant were significantly less likely to develop atopic dermatitis, or eczema, as toddlers, a researcher here found.
At age 2, children with prenatal dog exposure had a significant reduced risk of eczema compared to children whose mothers were not exposed to dogs (OR 0.48, 95% CI 0.30-0.76, P=0.002), reported Gagandeep Cheema, MD, of Henry Ford Hospital in Detroit, and colleagues.
But the significance of this effect did not extend into older childhood. The reduced risk of eczema for children with prenatal dog exposure only trended towards persistence of this effect at age 10, but was still non-significant (OR 0.62, 95% CI 0.37-1.05, P=0.077). Click here to learn more.
