Association of Parental Socioeconomic Status and Newborn Telomere Length

Key Points Question Is parental socioeconomic status associated with telomere length at birth? Findings This cohort study found that early biological aging, reflected by shorter telomere length in newborns, was associated with lower parental socioeconomic status. A higher vulnerability was observed in boys compared with girls. Meaning Addressing socioeconomic disadvantages very early in life may improve molecular longevity and overall health for the next generation.
