Physical immobility of children is quite serious and children who do not engage in regular physical increase their chances of putting on excess weight. Researchers studied the physical activity of 133 children over a three week period using an accelero-meter to measure each child’s level of physical activity. They observed that obese children were 35% less active on school days and 65% less active on weekends as compared to normally lean children.This proves that staying physically inactive leaves unused energy in the body and most of which is stored as fat.
Physical sluggishness as a child usually follows physical inactivity as an adult. In a fitness survey of 6,000 adults, researchers found out that 25% of those who were considered active at ages 14 to 19 were also active adults, compared to 2% of those who were inactive at ages 14 to 19, who were now said to be active adults. Researchers studied 16 men over a 14 day period and fed them 50% more than energy daily energy requirement through fats and carbohydrates. They discovered that carbohydrate overfeeding produced 75–85% excess energy being stored as body fat and fat overfeeding produced 90–95% storage of excess energy as body fat.
Many children fail to exercise because they are spending time doing stationary activities such as computer usage, playing video games or watching television. TV and other technology may be large factors of physically inactive children. Researchers provided a technology questionnaire to 4,561 children, ages 14, 16, and 18. They discovered children were 21.5% more likely to be overweight when watching 4+ hours of TV per day, 4.5% more likely to be overweight when using a computer one or more hours per day, and unaffected by potential weight gain from playing video games A randomized trial showed that reducing TV viewing and computer use can decrease age-adjusted BMI; reduced calorie intake was thought to be the greatest contributor to the BMI decrease.
Technological activities are not the only household influences of childhood obesity. Low-income households can affect a child’s tendency to gain weight. Over a three week period researchers studied the relationship of socioeconomic status (SES) to body composition in 194 children, ages 11–12. They measured weight, waist girth, stretch stature, skin folds, physical activity, TV viewing, and SES; researchers discovered clear SES inclines to upper class children compared to the lower class children Childhood inactivity is linked to obesity in the United States with more children being overweight at younger ages.
