The study, published in the Journal of Epidemiology and Community Health, examined data from 18,171 mother-child pairs from the Taiwan Birth Cohort Study.

Multidomain developmental vulnerability was defined as delays or lower performance in two or more developmental domains. The researchers clarified that this was used as a population-level screening measure, not as a clinical diagnosis. The study found a reverse J-shaped association between maternal age and developmental vulnerability. Children born to younger mothers aged 20–24 ye
