  • + Notes

    The indicator shows self-reported data collected through Computer Assisted Telephone Interviewing (CATI). Estimates were weighted to adjust for differences in the probability of selection among respondents and were benchmarked to the estimated residential population using the latest available Australian Bureau of Statistics mid-year population estimates.

    Mobile phone numbers have been included since the 2012 survey (using an overlapping dual-frame design) because of diminishing coverage of the population by landline sampling frames (<85 % since 2010). Associations between mobile-only phone users and some health indicators, even after adjusting for age, sex and region, were observed in 2012. Thus significant differences that were observed between 2011 and 2012 should be reported with caution, as they will reflect both real and design changes. LL/UL 95%CI = lower and upper limits of the 95% confidence interval for the point estimate.

      Latest available information

      Latest available data for adults in NSW

        • 52.3% of adults aged 16 years and over (59.0% of men and 45.8% of women) were overweight or obese as estimated from the 2015 NSW Adult Population Health Survey (self-reported using Computer Assisted Telephone Interviewing or CATI).

        • 61.1% of persons aged 18 years and over (68.3% of males and 53.7% of females) in NSW were overweight or obese as estimated from the 2011-12 Australian Health Survey (interviewer-administered questionnaire and measured weight and height).

      Latest available data for secondary school students in NSW

        • 20.6% of students aged 12-17 years (24.5% of boys and 16.1% of girls) were overweight or obese as estimated from the 2014 NSW School Students Health Behaviours Survey (self-completed questionnaire).

        • 22.8% of students in years K, 2, 4, 6 and 10 (24.0% of boys and 21.5% of girls) were overweight or obese as estimated from the 2010 NSW Schools Physical Activity and Nutrition Survey (measured).

      Latest available data for children in NSW

        • 22.8% of students in years K, 2, 4, 6 and 10 (24.0% of boys and 21.5% of girls) were overweight or obese as estimated from the 2010 NSW Schools Physical Activity and Nutrition Survey (measured).

        • 25.6% of children aged 5-17 years were overweight or obese as estimated from the 2011-12 Australian Health Survey (measured).

      Latest available data for adult Aboriginal persons in NSW

        • 57.5% of Aboriginal adults aged 16 years and over were overweight or obese as estimated from the 2015 NSW Adult Population Health Survey (self-reported using CATI).

      Overall trends in NSW

      Self-reported data on overweight and obesity have been collected for adults in NSW since 1997 through the NSW Population Health Survey and since 1977-78 through the Australian Health Surveys, National Health Surveys (from 1995). Measured data on overweight and obesity have been collected for adults in NSW through the National Nutrition Survey (1995) and the Australian and National Health Survey (2011-12 and 2007-08 respectively).

      Self-reported data on overweight and obesity have been collected for students in NSW since 2005 through the NSW School Students Health Behaviours Survey and measured data on overweight and obesity have been collected for students in NSW since 1985 through the Australian Health and Fitness Survey and the NSW Schools Fitness and Physical Activity Survey (1997) and the NSW Schools Physical Activity and Nutrition Survey (2004, 2010 and 2014).

      Parent-reported data on overweight and obesity have been collected for children in NSW since 2007 through the NSW Population Health Survey. Measured data on overweight and obesity have been collected for children in NSW since 2008 through the Australian Health Survey.

      Prevalence estimates, although differing slightly between surveys because of different sampling frames, participation rates and modes of collection (telephone versus self-completed questionnaires versus face-to-face personal interview versus measured) have all been increasing over time although the rate of increase has lessened.

      Hospitalisations attributable to high body mass

      A total of 39,289 hospitalisations were attributed to high body mass in NSW in 2013-14, which was approximately 1.3% of all hospitalisations. The rate of hospitalisations attributed to high body mass decreased by more than 18% in the decade up to 2012-13. This was chiefly due to the rate decreasing by more than 20% between 2009-10 and 2011-12 caused by a change in coding of diabetes in hospital data. This coding change was implemented in NSW hospitals on 1 July 2010. In the decade up to 2009-10, the rate of hospitalisation attributable to high body mass increased by 8% in NSW. The hospitalisation rate in males was 40% greater than the rate in females throughout the decade.

      Deaths attributable to high body mass

      A total of 2,693 deaths were estimated to be caused by high body mass in NSW in 2013, which was approximately 5.5% of all deaths. The rate of death attributed to high body mass has decreased in the decade up to 2013 and the decline was similar in males and females.

    • Introduction: Overweight and obesity

      High body weight as a health risk factor

      There are health problems associated with being either underweight or overweight. Although underweight can be a serious risk to health (leading to malnutrition and other health problems such as osteoporosis), public health focus is on excess body weight, as this is a much greater problem in the Australian population.

      Excess weight, especially obesity, is a risk factor for cardiovascular disease, Type 2 diabetes, some musculoskeletal conditions and some cancers. As the level of excess weight increases, so does the risk of developing these conditions. In addition, being overweight can hamper the ability to control or manage chronic disorders.

      Excess weight in children increases the risk of poor health, both during childhood and later in adulthood. Children who are overweight or obese are at greater risk of developing chronic conditions such as asthma and Type 2 diabetes and may experience negative social and mental wellbeing.

      Body Mass Index (BMI)

      High and low body weight categories are determined using Body Mass Index (BMI). BMI is calculated by a person’s weight in kilograms divided by the square of their height in metres (kg/m2). A person considered overweight or obese has a BMI of at least 25 kg/m2. For more details on the BMI, see the Methods section.

      For persons aged 18 years and over, the body weight categories are: underweight (BMI less than 18.5), healthy weight (BMI from 18.5 to 24.9), overweight (BMI from 25.0 to 29.9) and obese (BMI of 30.0 and over). Obesity was further classified into: Obesity Class I (BMI between 30.0 and 34.9), Obesity Class II (BMI between 35.0 and 39.9) and Obesity Class III (BMI of 40.0 or over).

      For children and adolescents, while the same categories to describe body weight are used, the BMI range for each category varies by individual year of age of the child and is different for boys and girls. These category ranges comply with an international standard (Cole et al. 2000; Cole et al. 2007).

      High body weight interventions

      The NSW Healthy Eating and Active Living Strategy 2013-2018 provides a whole of government framework to promote and support healthy eating and active living in NSW and to reduce the impact of lifestyle-related chronic disease.

      The Strategy has four key strategic directions:

      • Environments to support healthy eating and active living;

      • State-wide healthy eating and active living support programs;

      • Healthy eating and active living advice as part of routine service delivery; and

      • Education and information to enable informed, healthy choices.
