AllerGen CHILD Study Findings Connect Infant Sleep Duration with Cognitive and Language Skill Development

AllerGen CHILD Study researchers have found that infants who regularly sleep less than 12 hours total in a 24-hour period have poorer cognitive and language skills by two years of age compared to infants who sleep more.

“Short sleep duration and symptoms of Sleep Disordered Breathing (SDB) ranging from snoring to sleep apnea have been associated with multiple health, learning and behavioural problems in children,” says Dr. Piush Mandhane, an associate professor of pediatrics at the University of Alberta and leader of the CHILD Study’s Edmonton site. “We were interested to find out if limited sleep time and sleep disruption affected cognitive and language development in preschool children. Our study found that short nighttime sleep was associated with a significant decrease in cognitive development using a standardized test of mental and motor development."

In a second study, Dr. Mandhane and the team of CHILD researchers identified four distinct types of SDB that occur in infants, along with unique risk factors associated with each.

Both studies were published in the August 2018 issue of Sleep Medicine.

CHILD Study: 3,500 Children Could Change Canada's Approach to Fighting Chronic Diseases

Canadian Healthy Infant Longitudinal Development (CHILD) study examines how a child's environment during pregnancy, and in the first few years of life, can interact with genetics to affect the risk of developing allergies, asthma, type 2 diabetes and other chronic diseases

If just 24 children can help scientists discover that Caesarean sections and formula feeding may deprive babies of the protective gut bacteria needed for lifelong health, just imagine what will be discovered by collecting a wide range of health information from some 3,500 children. Scientists believe it will influence everything from health policy and building codes to parenting decisions for decades to come.

Those 3,500 children, along with their mothers and about 2,600 fathers from Vancouver, Edmonton, Toronto and several communities in Manitoba, are on the front-lines of the Canadian Healthy Infant Longitudinal Development (CHILD) Study, a national birth cohort study funded in part by the Allergy, Genes and Environment Network (AllerGen).

AllerGen researchers awarded CIHR grants

CHILD research team awarded five-year CIHR grant


Dr. Malcolm Sears, an AllerGen research leader and a professor of medicine at McMaster University, together with a team of CHILD researchers from across Canada, has received a five-year operating grant, valued at over $1 million, from the Canadian Institutes of Health Research (CIHR) Institute of Circulatory and Respiratory Health. The CHILD Study application was ranked first among 65 proposals reviewed by the respiratory committee in the March 2014 competition.

The Sandbox Project calls for support for the CHILD Study

The Sandbox Project's Environment Working Group writes a letter to encourage the continuation of the Canadian Healthy Infant Longitudinal Development (CHILD) Study

Dear Honorable Minister,

On behalf of The Sandbox Project, we wish to draw your attention to, and encourage your support for, the continuation of the Canadian Healthy Infant Longitudinal Development (CHILD) Study, an internationally recognized, longitudinal population-based birth cohort investigating the origins of chronic childhood illnesses.   The CHILD Study represents a key tool for understanding the impact of the environment on children’s health, and the epidemic of asthma, allergy and many other chronic diseases of later childhood and adulthood in Canada. The mission of The Sandbox Project is to make Canada the healthiest place on earth for kids to grow up – what can be learned from the CHILD Study is critical if we hope to succeed.
