Auditory Risk Factors at Birth and Language Development at 2 Years of Age: A Longitudinal Analysis.

Aim. To analyze the relationship between auditory risk factors at birth and subsequent language development in toddlerhood. Methods. Participants are 136 children from a longitudinal birth cohort follow-up at age 2 years. They were divided into 2 groups: One comprising 105 children without hearing risk factors at birth and another comprising 31 children with auditory risk factors at birth but normal hearing. Results. In children with and without risk factors, the combination of socio-emotional, socio-economic, and auditory risk factors at birth significantly predicted language development at age 2 years. Family socio-economic status had a significant impact on overall child development, even after controlling for socio-emotional development and the presence of risk factors. Conclusions. The study was conducted in an upper-middle income country with a socialized health care system. It underscores the importance of a holistic approach to early childhood language development, taking into account biological, socioeconomic, and emotional factors.
