Ontario Student Drug Use and Health Survey (OSDUHS) [Canada]

 
Abstract:
The Ontario Student Drug Use and Health Survey (OSDUHS) is a population survey of Ontario students in grades 7 to 12. The OSDUHS began in 1977 and is the longest ongoing school survey in Canada, and the second longest in North America. This self-administered, anonymous survey is conducted across the province every two years with the purpose of identifying epidemiological trends in student drug use, mental health, physical activity, and risk behaviour, as well as identifying risk and protective factors. Typically, the OSDUHS surveys thousands of students in over 150 elementary and secondary schools across Ontario.

This survey is important because it provides current and reliable information about the health risk behaviour, attitudes and beliefs of Ontario adolescents, and tracks changes over time. Findings from the OSDUHS have been widely used by health, education, and government officials in setting health priorities and facilitating preventative policies, programs and services that address youths' needs.

The OSDUHS began as a drug use survey, but is now a broader study of adolescent health and well-being. Topics covered include: tobacco, alcohol and other drug use and harmful consequences of use, mental health indicators, physical health indicators, health care utilization, body image, gambling and video gaming behaviours and problems, violence and bullying, criminal behaviours, school connectedness, and family life.

Ontario Student Drug Use and Health Survey OSDUHS
The purpose of the Ontario Student Drug Use and Health Survey (OSDUHS) is to examine epidemiological trends in student drug use, mental health, physical health, and risk behaviours, as well as identifying risk and protective factors. The OSDUHS, now spanning over 30 years, is the longest ongoing study of a youthful population in Canada, and the secondlongest in North America.

Sampling Procedure:
The 2009 OSDUHS employed a stratified (region and school type) two-stage (school, class) cluster sample design, and oversampled schools in northern Ontario and in six public health regions.

The 2009 school sample is based on a longitudinal sample commencing in 2001. The school sample selection occurred as follows:

a) To select the initial 2001 sample, schools were drawn from Ontario’s Ministry of Education and Training’s enrolment data, and were stratified according to the four design regions.
b) Within each regional stratum, a random selection of schools was chosen, separately for elementary/middle schools and secondary schools. Schools were selected with probability proportional to enrolment size (meaning that larger schools have a greater probability of being selected). The schools that participated in 2001 were invited to participate in cycles since then, including the 2009 cycle. In addition, in 2009 new schools were also selected for specific public health region over-samples.
c) If a selected school could not participate, or if it had closed, a replacement school from the same region was selected. The sampling frame for new schools and replacement schools was based on the Ministry of Education and Training’s 2006/2007 enrolment data (most recently available).

Universe:
For all OSDUHS surveys, the target population is all students enrolled in the public and Catholic school systems. Grades 7-12 are included. Thus, it excludes those enrolled in private schools, special education classes, those institutionalized for correctional or health reasons, those on Indian reserves and Canadian Forces bases, and those in the far northern regions of Ontario (a total of about 7% of Ontario students).

Currently, over 150 graduate students and postdoctoral fellows pursue their studies under the direction of scientists in the four research departments: Clinical Research, Neuroscience Research, the PET Centre, and Social and Epidemiological Research. Our trainees come from a variety of disciplines, and go on to become very influential contributors to the substance use and mental health field.

Aggregate data is available in table form through CAMH's publications and reports.
