Final answer:
The best estimate of the percentage of children and adolescents with obesity, considering the given data, is approximately 18%.
Step-by-step explanation:
The percentage of children and adolescents with obesity can be derived from the data provided, which gives a range of obesity rates. Among these, the best estimate for the average percentage of people with obesity, specifically children under age five, seems to be in the range of 16-21.45%. Considering the information given about the rise in childhood obesity and the obesity epidemic in the United States, where over 70% of Americans are overweight or obese, the number that falls within the provided range is approximately 18%.
The percentage of children and adolescents with obesity is approximately 18 percent. According to the information provided, in the 1990s, most states reported less than 10 percent obesity rates, and by 2010, nearly 36 percent of adults over 20 years old were obese. These studies also find that the level of childhood obesity is rising. Therefore, the best estimate for the percentage of children and adolescents with obesity is approximately 18 percent.
