What is Mantra to Prevent Childhood Obesity?
Being physically very active is the mantra to prevent pediatric obesity!
Pediatric obesity means presence of obesity (and overweight) in infants, children and adolescents ranging in age from birth to the age of 17 or 18. Obesity, that is having too much body fat, is different from being overweight which is ‘weighing too much’. Children grow at different rates, so their BMI is not a specific number. BMI in children is calculated based on their weight and height taking into account their gender and age. It is listed as a percent. Children aged 2 and older could be obese if their BMI is at or higher than 95th percentile.
Previous researches pointed to the concept that diet and physical activity were two prime concerns as regards prevention of obesity in children. The researchers have previously believed that some children put on excess weight compared to others due to the genetic factor; however the environmental factors influence their energy intake and expenditure. This led to restriction of energy providing carbohydrate and fatty food in the diet of the child at risk of becoming overweight. Although diet restriction and exercise helps obese adults to lose weight, it was not found to work in young people. Most studies could not find a consistent link between diet, physical activity and body fat in children.
An interesting debate published in the International Journal of Obesity suggests that ‘we can help youths to develop healthy bodies if we focus more attention on promoting vigorous physical activity rather than restricting energy intake’. The new research focuses on the effect of physical activity on body composition rather than weight. The researchers found that vigorous physical activity (PA) ‘stimulates stem cells to differentiate into bone and muscle cells rather than to fat cells; that is, the ingested energy and nutrients tend to be partitioned into lean tissue rather than into fat tissue’. Researchers felt that BMI could not indicate the level of obesity in children since the use of ‘weight’ for calculating BMI includes both fat mass and fat-free mass. Vigorous physical activity increases muscle and bone mass and reduces fat mass, so the net BMI does not change significantly.
Since the area of research on stem cell differentiation is relatively very new, the complex mechanisms of its working is yet to be factually determined. Two things are however very clear – first, mechanical signals stimulating the deposition of energy (nutrients) into bone and muscle tend to direct nutrients away from fat, and secondly, mechanical signals that prevent development of fatness do not necessarily imply that they effectively reduce fatness of already obese subjects. Therefore, recent studies emphasize on prevention of childhood obesity rather than treatment of the same.
On the whole, what the scientists are suggesting is that pediatric obesity can be prevented if we concentrated more on making kids take up regular vigorous physical activities such as dancing, athletics, strength training and other physical sports rather than emphasizing on dietary changes that involve restriction of energy intake which can harm their growth and physical as well as mental development.
