Final answer:
Obesity rates have tripled in children aged 6-19 since the 1980s, presenting significant health risks like type 2 diabetes and heart disease. This trend is linked to poor diet and lack of physical activity.
Step-by-step explanation:
Obesity has tripled in children aged 6-19 years old since the 1980's. Obesity is a condition defined by having excess body fat, and it is different from merely being overweight, which pertains to weighing more than what is considered healthy. Since the 1980s, the rise in childhood obesity has been a significant health concern, indicating a trend where children today are considerably heavier than those from previous generations.
This increase in childhood obesity is worrisome because of its association with various health issues, such as type 2 diabetes and heart disease, indicating a shift in the metabolism and dietary habits of the younger population. The factors contributing to this alarming trend include the widespread availability of high-calorie, low-nutrient processed foods and a decrease in physical activity among children.
