Why did we need this survey?Why did we need this survey?
Peel Health’s Child Health Report 2002 revealed:• In 2001, one-third of Ontario students in grades seven to
13 used an illicit drug in the past year.
• In 1996/97, 28 per cent of Ontario teens had two or more sexual partners.
• As of 1996, 29 per cent of Canadian girls and 35 per cent of Canadian boys aged 7-13 years were overweight.
But the data in the Child Health Report relied heavily on sources across Canada… not Peel.

Do Peel children experience the same Do Peel children experience the same health risks as children across Ontario health risks as children across Ontario and Canada?and Canada?
We were not sure, and we needed to know.
The School Health Assessment Survey 2004 gave us a Peel-specific picture of the health of our children.
Peel Health
The sample…The sample…
• Estimated we would need approximately 6,000 students in Peel – or about 1,000 students per grade (7 to 12).
• 56 schools in Peel were randomly selected -33 elementary and 23 secondary schools.
• Randomly selected 2 to 3 classes per grade in elementary schools and up to 4 classes per grade in high schools.
Peel Health
The survey included questions on…The survey included questions on…
• eating habits and physical activity• tobacco, alcohol, marijuana and other drugs • self-esteem, mental health and relationships • dental health • injuries• sun safety • safety and bullying in the community and at school• height and weight (as measured by a Public Health Nurse)• student’s age, sex and grade• Plus… sexual health for secondary-age students.

What happened in each classroom?What happened in each classroom?
• Public Health Nurses (PHN) checked consents and gave out
incentives.
• Instructed students and distributed surveys.
• Helped students with survey, if necessary.
• Took one student at a time to private area for
height/weight measurement.
• Wrapped up survey and provided support to students.
Peel Health
Data AnalysisData Analysis• Data were weighted to population data based on a post-
adjustment method which adjusted for under-sampling and over-sampling particular grades in Peel.
• Data collected from the survey were analyzed using the SPSS statistical software package Version 13.0 and Epi Info 2000 version 3.2.
• Blank responses and multiple responses (when only one response was required) were excluded from the analysis if both totaled less than 5%. If higher than 5% these were noted in the report. “Don’t know” was included in the analysis if this was part of the question.
Peel Health
The results were released on The results were released on May 19, 2005May 19, 2005• General results in specific
topic areas across Peel overall and by sex and grade.
• Can compare Peel to the rest of Ontario and Canada, where applicable.
What’s not available:
• Data by individual school or family of schools.
Peel Health
Response RateResponse Rate• 11,960 students were invited to participate in the
survey.
• 7,853 (66%) completed the survey.

• Approximately 2% of students either refused to have their height/weight measured or were erroneously recorded by the Public Health Nurse.

Body Mass Index and Body ImageBody Mass Index and Body Image• BMI-for-age and sex charts created by the United States
Centers for Disease Control and Prevention (CDC) were used to describe body weight.
Underweight BMI-for-age < 5th percentile
Normal (healthy weight) BMI-for-age 5th percentile to < 85th percentile
At risk of overweight (overweight) BMI-for-age 85th percentile to < 95th percentile
Overweight (obese) BMI-for-age > 95th percentile

Data LimitationsData Limitations• We could not adjust for clustering because of our
agreement with the participating school boards to not identify any schools in any report or data set.
• Comparison with Ontario data was not always possible as survey questions were modified, different grades were sampled, and different analysis methods were used.
• Seasonal differences. The survey was conducted using students sampled from two different cohorts. One survey occurred in the spring and the other in the fall in two different school years.

What are the benefits?What are the benefits?
1. Peel-specific data means Peel-specific solutions.
2. Less time and money spent on initiatives that don’t meet our students’ needs.
3. Happier, healthier children with brighter futures.
Peel Health
ConclusionsConclusions• In Peel, information about health and health-
related risk behaviours of the adolescent population aged 12 to 18 years is not always available at the Regional level.
• The survey was the largest of its kind at the regional and provincial level.
• We now have some Regional level data on several health behaviours for youth aged 12 to 18.
