The causes of overweight in children
Genetic Factors
Children whose family members are overweight may be at an increased risk of becoming overweight themselves. Although weight problems run in families, not all children with a family history of obesity will be overweight. Genetic factors play a role in increasing the likelihood that a child will be overweight, but shared family behaviors such as eating and activity habits also influence body weight.
Lifestyle
A child's total diet and his or her activity level both play an important role in determining a child's weight. The increasing popularity of television and computer and video games contributes to children's inactive lifestyles. The average American child spends approximately 24 hours each week watching television-time that could be spent in some sort of physical activity.
