In 2011, the NSW Department of Health conducted the fourth NSW Secondary Schools Health Behaviours (SSHB) Survey. It was part of the triennial Australian Schools Students Alcohol and Drugs (ASSAD) Survey, which began in 1984.
The 2011 survey involved 7,966 students in Years 7-12 from NSW Government, Catholic and Independent secondary schools.
It was based on a self-administered questionnaire, which included questions on nutrition and eating, physical activity and height and weight (including perception of body mass). Trends in the results from the 2011 survey and previous SHHB and ASSAD surveys were examined.
- Around one in five (20.4%) students was overweight or obese, based on self-reported height and weight.
- Between 2008 and 2011, there was no significant change in the proportion of students who were overweight or obese.
- One in 10 students who perceived themselves to be too thin or about the right weight were assessed as overweight or obese, based on their self-reported height and weight.
· Less than half (45.5%) of the surveyed students consumed an adequate amount of fruit every day.
· One quarter (25.7%) consumed an adequate amount of vegetables every day.
· Over a quarter (23.4%) consumed adequate amounts of grain foods, such as bread, rice and pasta.
· Less than four in 10 (41.5%) students drank reduced fat or skim milk, as recommended for older children and young people.
· Trends over time show that there has been an increase in students meeting the minimum recommended intakes of fruit, vegetables, and bread and cereals. Similarly, more students are consuming lower fat or reduced fat milk.
· Over half (55.5%) drank less than five cups of water each day.
· A quarter drank soft drink, energy drinks, fruit juice or cordial on five or more occasions each week.
- Just over one in 10 (13.1%) had the recommended daily amount of physical activity.
- Just over nine in 10 (92%) were sedentary for at least two hours a day when not at school (not including doing homework).
- Between 2005 and 2011, there was no significant change in the proportion of students who did the minimum recommended daily amount physical activity.
- Between 2002 and 2011, there was a significant increase in the proportion of students who were sedentary for more than two hours a day when not at school (not including doing homework).
