We examined whether adults born preterm at very low birth weight (VLBW; <3.3 pounds) differ from term-born adults in autism-spectrum traits, and whether among VLBW adults, growth in infancy is associated with these traits.
A total of 110 VLBW and 104 term-born adults of the Helsinki Study of Very Low Birth Weight Adults completed the Autism-Spectrum Quotient yielding total, social interaction, and attention to detail sum scores.
VLBW adults scored higher than term-born controls on social interaction sum score, indicating higher autism-spectrum traits. In contrast, they scored lower on attention to detail sum score, indicating lower autism-spectrum traits.
