Answer:
The number of overweight children in Australia has doubled in recent years, with a quarter of children considered overweight or obese. Causes of obesity in children include unhealthy food choices, lack of physical activity and family eating habits.
This rise in the number of overweight children is disturbing, because it causes health problems and can lead to social problems. Overweight children are more likely to be teased by their peers or to develop low self-esteem or body image problems. Once children are overweight, it requires a lot of effort and commitment for them to return to a healthy weight.
Overweight and obesity in children are among the most important risks to children’s long and short-term health. Overweight children are very likely to become overweight adults.
Risk factors for childhood obesity
Your body stores unused energy (kilojoules) as body fat. To maintain a healthy weight, you need to use (or ‘burn’) the energy from the foods you eat. If you eat more than you use, your body will store the extra energy as fat.
Factors that may cause children to become overweight and obese include:
- Food choices – these include choosing high fat and sugary foods instead of healthier options.
- Lack of physical activity – Australian children are less active than they were in the past.
- Spending a lot of time on sedentary pursuits – Australian children watch, on average, around 2½ hours of television a day, as well as spending time using computers and other electronic games. It seems that these pastimes are replacing active ones.
