The authors analyzed data from the Millennium Cohort Study (MCS), British Cohort Study (BCS70) and National Child Development Study (NCDS), whose initial cohorts comprised over 56,000 individuals. The goal of the study was to determine whether birth weight was associated with childhood/adolescent stuttering. The authors reported the results suggested birth weight is not a clinically useful predictor of childhood or persistent stuttering.
