Childhood obesity is characterized by the accumulation of excess fat in the body of the child, which is diagnosed by calculating the body mass index. This indicator is the ratio of body weight in kilograms. The main factor in causing obesity is the imbalance between the intake of energy and material consumption.
Children are particularly rapidly gaining weight during prolonged bed rest and increased caloric intake. In addition, the developments of obesity are important genetic factors. Prerequisites for their implementation are usually physical inactivity and overeating. More often obese parents have obese children.
Obesity leads to a rise in blood pressure, sleep disorders, development of diabetes, cardiovascular disease, liver disease, skin infections, asthma and cancer. However, obesity has a negative impact not only on the physical body but also affects the mental health of the child. Obesity complicates communication and social adaptation of the child, lowers self-esteem and lead to depression.
In order to establish the relationship between obesity and cancer, American scientists have long-term study about the problem of obesity in children. After processing data the researchers found an obvious connection between childhood obesity and the development of colorectal cancer in later life.
