Developmental, sensory and behavioral outcomes among infants and toddlers with prenatal alcohol exposure

Background

Prenatal alcohol exposure (PAE) can disrupt children’s neurodevelopment and exert lasting influences on overall child well-being and family functioning. A comprehensive exploration of developmental outcomes in infants/toddlers with PAE seen for a diagnosis on the fetal alcohol spectrum can inform early identification and intervention.

Aims

To describe the prevalence and patterns of neurodevelopment, sensory processing, and emotional and behavioral functioning in a clinical sample of infants/toddlers with PAE.

Methods

In this retrospective analysis, clinical data from 125 infants/toddlers with PAE, aged 2–42 months, assessed at the University of Washington Fetal Alcohol Syndrome Diagnostic and Prevention Network clinic were analyzed.

Results

Seventy-four to 87% of infants/toddlers demonstrated delayed development in one or more domains of the Bayley Scales of Infant and Toddler Development (n = 125). Adverse developmental outcomes were significantly correlated with PAE and/or postnatal risk factors. All 93 infants/toddlers with a complete Infant/Toddler Sensory Profile obtained definite difference scores in at least one quadrant/section. Over half of infant/toddlers with a completed Child Behavior Checklist/1½− 5 had total problem scores in the borderline or clinical range.

Conclusions

Findings suggest that several domains of child functioning may be vulnerable to the teratogenic impact of PAE, and that these delays are evident in the first years of life. Early screening, ongoing monitoring and comprehensive assessment is needed to facilitate earlier identification and guide clinical intervention.
