Sleepless babies grow up with temper tantrums
A study recently published in Developmental Neuropsychology found a link between poor infant sleep and behavior and attention problems in toddler age. The research discovered that one-year-olds who experienced fragmented sleep were more likely to have difficulties concentrating and to exhibit behavioral problems at three and four years of age.
The research was led by Prof. Avi Sadeh of Tel Aviv University’s School of Psychological Sciences and conducted by a team that included his TAU colleagues Yael Guri and Prof. Yair Bar-Haim; Dr. Gali De Marcas of the Gordon College of Education in Haifa; and Prof. Andrea Berger and Dr. Liat Tikotzky of Ben Gurion University of the Negev.
The team assessed the sleep patterns of infants at TAU’s Laboratory for Children’s Sleep Disorders, where Prof. Sadeh is director. The initial study included 87 one-year-olds and their parents. They revisited the lab when the infants were three to four years old. According to the study, “Night-wakings of self-soothing infants go unnoticed by their parents. Therefore, objective infant sleep measures are required when assessing the role of sleep consolidation or sleep fragmentation and its potential impact on the developing child.”
To accomplish this, the researchers used wristwatch-like devices to objectively determine sleep patterns at the age of one, and in the follow-up visits they used a computerized attention test, the Spatial-Stroop task, to assess attentional executive control. They also referred to parental reports to determine signs of behavioral problems.
The results revealed significant predictive and concomitant correlations between infant sleep and toddler attention regulation and behavior problems. The study points to significant ties between sleep quality markers (sleep percentage and number of night wakings) at one year of age and attention and behavior regulation markers two to three years later.
