Fit for School, Fit for Life

Over the last 30 years childhood obesity rates have nearly tripled. This is a troubling trend as children who are obese are at risk of developing a range of problems. Growth and weight changes in early childhood may even impact school readiness and school achievement.
 
Other child health and developmental factors may play a role in emerging school readiness as well. Physical activity, sleep, and nutrition are all very important.
 
Fit for School, Fit for Life is a new study that uses the EDI to explore the impact of these early life factors on child development at school entry. The study features researchers from the Offord Centre for Child Studies, the Hospital for Sick Children, and St. Michael’s Hospital.
 
Fit for School, Fit for Life includes children from TARGet Kids!, a large research study of over 8,000 healthy children between 0-5 years of age. Children join through their pediatrician or family doctor.
 
When children visit for a scheduled appointment, doctors measure the following:
 
  • height
  • weight
  • waist circumference
  • lifestyle (nutrition, physical activity, and amount of screen time)
  • and collect a blood sample
 
Once these children enter kindergarten, the researchers ask their teacher to complete an EDI questionnaire. Teacher participation in the project is voluntary.
 
The main goal is to find out if there is a link between growth trajectories in early childhood and EDI vulnerability in junior and senior kindergarten.
 
The secondary goal is to examine whether other health factors are related to school readiness, including:
 
  • physical activity
  • sedentary behaviours
  • sleep
  • nutritional risk
  • cardiometabolic risk
  • risk of developmental delay
  • emotion regulation
 
If they are, do these affect the relationship between growth trajectories and school readiness?
 
This study is important as young children and their families regularly attend primary health care. This is a great time to provide preventive care. Finding early factors related to school readiness can help develop interventions and prevention strategies early, before children enter school. This means helping to set children on a healthy development path as early as possible.
 
The researchers plan to complete data collection in 2019.

EDI data show kids with late birthdays struggle compared to peers

Kindergarten students born between October and December are more likely to be vulnerable across all EDI domains.

The Globe and Mail published an article highlighting the problems young children face by the time they enter kindergarten. The article was based on EDI research from the Toronto District School Board.
The data raises questions for families registering their children for kindergarten. For children born in October, November, and December, is it better to wait a year?

TDSB is reminding principles to tell parents of their option to hold their late-birthday babies back a year.

Kindergarten is voluntary, but children must attend Grade 1 when they are six. But children who turn six after the first day of school can wait another year. That gives parents the option of holding their children back if they are born later in the year.

EDI in the News
EDI results question FDA warning on anesthesia
A new U.S. Food and Drug Administration warning that general anesthesia may harm brain development in children under 3 is being questioned by Canadian doctors, in part because of two studies using EDI data.

The Globe and Mail published an article citing two studies that show the relationship between early exposure to anesthesia and later EDI scores.

“Likely, the impact of delaying surgery is far more significant than any effect of the anesthetic on neurodevelopment,” Dr. Jason Maynes told the Globe and Mail.
EDI informs NWT Early Child Development Action Plan
Children in Northwest Territories are lagging in key areas of their development, especially in smaller communities.

CBC News reported on EDI results in the territory as leaders use the data to update their early childhood development action plan.
Cape Breton workshop spurred by EDI results
Communities in western Cape Breton, Nova Scotia came together to talk about how to better care for children in their early years.

CBC News reported on the event, organized by councillor Jim Mustard, who cited high EDI vulnerability rates in his community as a catalyst for the event.
Impact of chronic illness may have snowball effect
Research from Telethon Kids Institute shows children with a chronic illness have a 35% increased risk of being developmentally vulnerable compared to their typically developing peers.

The research was based on results from the 2009 Australian Early Development Census.

"If chronic illness interrupts a young child's development, they may start school not ready to learn, and they will struggle to meet the demands of school," lead author Megan Bell told ScienceNetwork Western Australia.
EDI at SRCD 2017
The Biennial Meeting for the Society for Research in Child Development (SRCD) was held in Austin, Texas on April 6-8, 2017. The conference featured over 6,000 child development professionals and researchers connecting and sharing information and ideas.

The EDI team traveled to Texas to present three posters at the conference. PDF copies are available on our website.
EDI at Psychiatry Research Day
McMaster’s 29th annual Psychiatry Research Day took place on May 3, 2017 at Mohawk College. This year’s theme was Innovations and Controversies in Education Research.

The EDI team contributed six posters to the event. PDF copies are available on our website.
