Obesity in Children and Adolescents

Childhood Obesity Facts

Obesity means an excess amount of body fat. No general agreement exists on the lowest definition of obesity in children and adolescents, unlike standards for adults. Nevertheless, most professionals accept published guidelines based on the body mass index (BMI) -- modified for age, pubertal stage, and gender -- to measure obesity in children and adolescents. Others define pediatric obesity as body weight at least 20% higher than the healthy weight range for a child or adolescent of that height, or as a body fat percentage above 25% in boys or above 32% in girls.

Although rare in the past, obesity is now among the most widespread medical problems affecting children and adolescents living in the United States and other developed countries. About 15% of adolescents (12-19 years of age) and children (6-11 years of age) are obese in the United States according to the American Obesity Association. These numbers have continued to increase since at least the early 1990s. Pediatric obesity represents one of our greatest health challenges.

Obesity has a profound effect on a patient's life. Obesity increases the patient's risk of numerous health problems, and it also can create emotional and social problems. Obese children are also more likely to be obese as adults, thereby increasing their lifelong risk of serious health problems such as heart disease and stroke.

If your child or teenager is overweight, further weight gain can be prevented. Parents can help their children keep their weight in the healthy range.

• In infancy, breastfeeding and delaying introduction of solid foods may help prevent obesity.
• In early childhood, children should be given healthy, low-fat snacks and take part in moderate-vigorous physical activity every day. Their television viewing should be limited to no more than seven hours per week (this includes sedentary entertainment like video games and internet surfing).
• Older children can be taught to select healthy, nutritious foods and to develop good exercise habits. Their time spent watching television and playing with computer or video games should be limited to no more than seven hours each week. Avoid snacking or eating meals while watching TV, movies, and videos. Avoid consumption of sugary products, especially those high in corn syrup or fructose derivatives, such as regular soda, pop, or cola (which some regions call "phosphate" drinks).

Running

Baby, we were born to run." Those immortal words by Bruce Springsteen may be more than just rock and roll lyrics, they may explain our evolutionary past. In this article, I'll describe the biological and social history of running, the health and fitness benefits (and risks) of running, how to get started, how to run properly, and some training techniques.

History of Running

The conventional thinking among most scholars is that early man (hunter-gatherers) ran in short sprints as a matter of survival -- to catch prey and escape danger -- but that running, and particularly endurance running, was merely a byproduct of the ability to walk and not a natural part of our evolution. The argument goes that (1) running is less efficient than walking (you burn more calories doing it), and (2) humans are poor sprinters compared to four-legged animals (who run much faster), and so it is concluded that we were never designed, or "born" to run. In evolutionary terms, scientists would say that we were not adapted for running.

But University of Utah biologist Dennis Bramble and Harvard University anthropologist Daniel Lieberman suggest otherwise. In their research, published in the prestigious journal Nature, they claim that the "roots of running may be as ancient as the origin of the human genus, and its demands a major contributing factor to the human body form." In other words, the act of running helped shaped the way we look.

The evidence for this claim is based on their work, in which they examined 26 traits of the human body that contribute to running skill, and in particular, long-distance running. Among the 26 traits are

1. a ligament that connects the back of the skull to the vertebrae in the spine that acts like a shock absorber,
2. our shoulders, which are separated from the head and neck (unlike apes), that allows our body to rotate while our head and eyes remain forward,
3. a taller body than apes, with a narrow trunk and waist, that allows for a more efficient running gait,
4. independent body movement between the hips, legs, and torso that counteract the twisting forces between the upper and lower body while running,
5. tendons and ligaments in the feet and legs that act like springs, and
6. a strong prominent buttocks that propel and stabilize the body during running.

Based on the evidence, they claim, "Running has substantially shaped human evolution. Running made us human -- at least in an anatomical sense. We think running is one of the most transforming events in human history. We are arguing the emergence of humans is tied to the evolution of running." If Bramble and Lieberman are right, then indeed the lyrics are true -- "Baby, we were born to run!"

Moving forward through the millennia to the ancient Olympic Games (776 B.C.) in Olympia, Greece, you find what could be the first documented competitive running event. It is reported that Koroibos, a cook from the city of Elis, won a 600-foot-long road race in those Olympics. But it was the ancient Greek messenger Pheidippides who set the stage for running in the modern era. In 490 B.C., Pheidippides ran 26 miles from the town of Marathon to Athens to announce the Greek victory over Persia in the Battle of Marathon. It was this event that inspired the running of the marathon (26.2 miles) in the first modern Olympic Games in Athens, Greece, in 1896, but organized running in the modern era had its roots earlier than that. The first collegiate races were sponsored by the Intercollegiate Association of Amateur Athletes of America in 1873, and in 1888, the Amateur Athletic Union held its first championships.

It was in the 20th century that the scope of organized and recreational running widened. The first NCAA national championships were held for men in 1921, and women's track and field became a part of the Olympic Games in 1928. Today, the International Association of Athletics Federations (IAAF) governs the sport internationally and includes more than 200 member nations. In the United States and Canada, track and field is one of the most popular high school sports with more than 950,000 high school students participating in events in each year. Recreationally, it is estimated that over 15 million Americans jog or run for fitness and health. In 2007, more than 20,000 runners completed the 111th Boston Marathon (the world's oldest marathon), and more than 39,000 participated in the New York City Marathon (the world's largest marathon -- and more than 90,000 applied to participate!). What do 15 million Americans know and love about running that you don't? Let's have a look.

Exercise

Exercise Overview

Exercise isn't a new idea. Records of people exercising go back to 1100 B.C., when the Greeks competed in the javelin throw, distance running, archery, and boxing. Hippocrates (460 B.C.-377 B.C.), the father of medicine, wrote that "eating alone will not keep a man well; he must also take exercise." Milo of Croton, in 6 B.C., discovered the Principle of Progressive Overload, in which he carried a calf every day on his shoulders and as it grew into a bull and got heavier, he got stronger (just like adding heavier dumbbells).

Skip ahead a thousand years to 1844, when the YMCA was founded and people started to do more formal exercise. Then, in 1896, the first modern Olympic games began, and by the early 1900s, gymnastics was mandatory for all American school children. In the late 1950s, things really picked up; Jack LaLanne had an exercise show on TV and the President's Council on Physical Fitness was created; the 1960s and '70s produced Jackie Sorensen and Jane Fonda exercise videos, Nautilus gyms, Ken Cooper coining the word "aerobics," and the running phenomenon started by George Sheehan, Jim Fixx, and others; and now today we have limitless types of exercise classes, technology built into every cardio machine, and all sorts of contraptions for building muscles. In this article, we'll take a more in-depth look at what exercise is all about.

The Benefits of Regular Exercise

Physical Fitness

Physical fitness is a measure of the condition of the body to perform during activities of daily living (light, moderate, and strenuous), formal exercise (like when you work out), and emergencies (as when you must escape from danger like a fire). The physical fitness of our nation is declining, proved by the rising rates of obesity, diabetes, some types of cardiovascular disease, and other medical conditions. To improve physical fitness, one must "practice," or work out. Emphasis should be on improving aerobic conditioning (stamina or endurance), muscular strength and endurance, and flexibility. The types of exercise necessary to do this are described next.

Breastfeeding

Introduction to Breastfeeding

Breastfeeding or bottle feeding your newborn baby is a personal decision. If you choose to breastfeed, it will be helpful if you are in a supportive environment and have resources to assist you with questions you may have or breastfeeding problems that may develop. The following breastfeeding tips may also be helpful:

• Consider attending a series of La Leche League meetings or reading La Leche League's book on breastfeeding (The Womanly Art of Breastfeeding) before the birth of your baby.
• Ask other breastfeeding mothers for advice.
• Join a supportive network including other like-minded mothers helps with the commitments of this style of feeding.
• If you are undecided at birth time, consider a one-month trial. It is easy to go from breastfeeding to bottle-feeding.
• The first month of breastfeeding is the most difficult, so if you get through that period, the rest will be easier.
