Recent research by Australian scientists has revealed an unexpected link between infant sleep quality and later development of autistic traits. The study, published in the journal Archives of Disease in Childhood, involved monitoring over 1,000 mother-child pairs, focusing on sleep patterns at ages 6 and 12 months, and assessing signs of autism when the children reached 2 and 4 years old.
The findings are significant. For instance, the study found that each additional hour of nighttime sleep at 6 months correlates with a 4.5% reduction in autistic traits by ages 2 to 4. Furthermore, there was a 22% lower likelihood of receiving an autism diagnosis by age 12 for those who slept longer.
The authors noted that "infant sleep may serve as an early indicator of autism." Similarly, at 12 months, infants who took longer to fall asleep had an increased risk of autism. Each additional 5 minutes required to fall asleep was associated with a 1.5% rise in autistic traits.
By the end of the study, 64 children had been diagnosed with autism, and the research revealed that 42% of these children had used melatonin in the preceding month, indicating that parents were already trying to manage sleep issues.
The researchers posit that infant sleep patterns, particularly nighttime habits, could serve as a crucial early indicator of autism, allowing for early detection and intervention opportunities. Autism affects 3.2% of children in Australia, making it the leading cause of disability among those under five years old as of 2016. While reliable diagnosis can be made by 24 months, Australian children are typically diagnosed at an average age of 45 months, missing the optimal window for early intervention.
This study emphasizes the importance of monitoring sleep patterns in infants as potential predictive markers for autism, highlighting the need for timely diagnosis and management strategies.
