Final answer:
Three long-term negative consequences of childhood obesity are the increased risks of developing type 2 diabetes, cardiovascular diseases, and a lower life expectancy, all of which illustrate the need for intervention and healthy lifestyle promotion.
Step-by-step explanation:
Three negative long-term consequences of obesity in children are an increased risk for type 2 diabetes, cardiovascular disease, and lower life expectancy.
Childhood obesity is a serious public health concern, involving excess body fat that negatively impacts a child's health. One major long-term effect is the significantly higher risk of developing type 2 diabetes due to obesity-induced insulin resistance. Additionally, obese children are more prone to develop cardiovascular diseases, such as heart attacks and strokes, as they grow older, often due to the accumulation of fatty deposits in their arteries.
Another troubling consequence is a lower life expectancy; obesity can shorten a person's life span due to the chronic health conditions it promotes. These risks underscore the importance of addressing obesity with effective strategies including regular physical activity and healthy eating habits.
