Why is there a growing concern over the physical fitness of children and adolescents? a. children and adolescents are overly concerned with exercise and fitness. b. a combination of poor nutrition and a sedentary lifestyle are leading to greater occurrences of obesity in children and adolescents. c. children and adolescents are getting too much of the wrong kind of exercise. d. although the diets of children and adolescents have improved over the years, participation in exercise has decreased .

The correct answer is B.

A combination of poor nutrition and a sedentary lifestyle are leading to greater occurrences of obesity in children and adolescents. This is true, especially in first world countries like the US. Children and adolescents are not as physically active as they used to be around 20 - 30 years ago due to advances in technology. The diets tend to be high in sugar and processed food as they are cheaper and easier to buy and easier to feed the kids with.

1. cold turkey (no outside ). about 90% of people who try to quit smoking do it without outside support -- no aids, therapy, or medicine. although most people try to quit this way, it's not the most successful method. only about 5% to 7% are able to quit on their own.

2. behavioral therapy. this involves working with a counselor to find ways not to smoke. together, you'll find your triggers (such as emotions or situations that make you want to smoke) and make a plan to get through the cravings.

3. nicotine replacement therapy. there are several types, including nicotine gum, patches, inhalers, sprays, and lozenges. they work by giving you nicotine without the use of tobacco. you may be more likely to quit with nicotine replacement therapy, but it works best when you use it with behavioral therapy and lots of support from friends and family. and remember that the goal is to end your addiction to nicotine, not simply to quit using tobacco.
