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.
