The Icelandic Prevention Model will be adapted to reflect local data and community needs, officials with Southwestern Public Health told CBC News.

“Local health status data is clear: reported use of alcohol, cannabis, tobacco, and other substances among youth is higher here than in Ontario,” said Peter Heywood, director of healthy communities at the health unit, which covers St. Thomas, Woodstock, and Oxford and Elgin counties.

More than one in three young people in that region reported using alcohol, cannabis and smoking a full cigarette for the first time in Grade 9, according to public health data, and more than half of young people reported drinking alcohol in the previous year, about 10 per cent higher than the Ontario average.

High school students will be asked to take a survey from Nov. 24 to Dec. 5, asking about substance use. They’ll be asked about their experiences in school, their communication with parents and siblings, their friendships, what they do in their spare time, how they see their mental health and what substances they use and how they perceive that use.

The results will be analysed and will guide how officials apply the Icelandic model locally, said Jessica Austin, a health promotor with Southwestern Public Health.

“The Icelandic Prevention Model was developed in Iceland by social scientists in the 90s (who) looked at factors that influence youth substance use to inform their community that had high substance rates on where they could focus their efforts to lower those rates,” Austin said.

Iceland’s teenagers used drugs and alcohol at the highest rates in Europe. Now, their rates are among the lowest.

Approach adopted worldwide

The approach has been adopted in communities around the world, including some in Canada. It focuses on prevention rather than targeting specific behaviours. Using the local data, the health unit works with community agencies, recreational facilities, faith groups, police officers, and school boards to give teens a sense of belonging.

“We know substance use is a complex issue and it requires a complex solution,” Austin said. “We’ve done a lot of work using provincial data, but now we will be able to work more effectively with the local data, to come together and get into the root causes.”

It typically takes a few years for change to happen, she added.

“I think everybody gets excited when we see the Icelandic graph sitting at one per cent for smoking rates and six per cent for alcohol-use rates, when we are sitting in the nearly 50 per cent alcohol-use rates for our youth,” Austin said.

“We would love to get down to that under the 10 per cent marker. In the short term, we want to at least get to the provincial rate.”
