what is one reason why the percentage of overweight teens increased over the past 50 year

Answer 1

One significant reason for the increase in the percentage of overweight teens over the past 50 years is the rise in sedentary lifestyles, largely driven by increased screen time and decreased physical activity. The prevalence of video games, smartphones, and television has contributed to a more sedentary lifestyle among teens, reducing the time spent on physical activities and exercise. Additionally, many schools have diminished physical education programs, further limiting opportunities for teens to engage in physical activity. This shift, combined with changes in dietary habits, has contributed to the rising rates of overweight and obesity among teenagers.
