3. Management and prevention of obesity and its complications in children and adolescents
Abstract
- Obesity in children and adolescents has reached alarming levels — 20%–25% of children and adolescents are overweight or obese, and 4.9% of boys and 5.4% of girls are obese.
- Rates of obesity have increased significantly in Australia from 1985 to 1995, with the prevalence of overweight doubling and obesity trebling.
- Body mass index (related to reference standards for age and sex) is recommended as a practical measure of overweight and obesity in children, and is used in monitoring individual progress in clinical practice.
- Obesity in childhood and adolescence may be associated with a range of medical and psychological complications, and can predispose individuals to serious health problems in adult life, including type 2 diabetes, hypertension, dyslipidaemia and non-alcoholic steatohepatitis.
- Obesity interventions for which there is some evidence include family support, a developmentally appropriate approach, long-term behaviour modification, dietary change, and increased physical activity and decreased sedentary behaviour.
- Prevention of obesity in children and adolescents requires a range of strategies involving changes in both the microenvironment (eg, housing, neighbourhoods, recreational opportunities) and the macroenvironment (eg, food marketing, transport systems, urban planning).
